I've got one out of four that is notchy, either ball bearings or bell housing it touching the stators occasionally.

 RonRC 2112 points

larry, I have not seen a kit, but I had a PDF of one I designed until I accidentally reformatted my external hard drive. I can retrace the template I made and post it if you like? It is a little of a beast to handle but lots of fun. You need lots of expo just to keep it from twitching! Happy flying!

Hi RonRc Thanks I would greatly appreciate any information that you would like to share. Template , prop info foam type ,Cf size and anything else . Great design thanks for your time..

 RonRC 2112 points

larry, I found an extra 300 profile views by doing an image search. All I did was print it on graph paper and scale it to my full size 300 (39in wingspan) and to this one (16in wingspan). This ran on a 2S lipo, a Red Brick 10A ESC, the Orange 415 micro RX, 3 HK-5320 Ultra-Micro Digital Servos, and a 5x3 prop. The only thing I changed when making my template was widening the horizontal fuse just before the tail section. I will trace it again and make another PDF. My micro Extra 300 is beat up pretty badly and I've been wanting to rebuild it. Ha ha! Happy flying!

 larry 9 points

Ron, Thank you for the info and for tracing it. What foam did you use so I can get some on order? Thanks for your time. Larry

 RonRC 2112 points

I used 3mm depron and it doesn't take much! Ha ha!

 kyrre 312 points

6/3 is too much for this motor.

 Dave 9 points

GWS5030 works very well with this motor

 sharpflyer 12 points

if you use 5X3 prop and 2S you can get 150grams wth it :)

 scruffy1 39 points

you'll be limited by clearance to a 4" prop, or at best 4.5" the gws4025 is a good choice (~23w), although the tgs 4.1x4.1e should also do okay (~31.5w)

 RonRC 2112 points

Thika22, I used a gws 4x2 prop on my scratch built Extra300. It worked quite well with a 500mAh 2S. I'm building a pusher F-18 and will use a 350mAh 3S.

 scruffy1 39 points

beware that a 3s will smoke the motor unless you are using a small prop* it certainly went fast for a brief time using 3s on a 5043 :(

 RonRC 2112 points

Scruffy, I've already bench tested it with a 3x2 prop and it has an AMAZING amount of thrust. Should make my lil pusher prop jet scream!!

 felixrising 16 points

Hi RonRC, what amount of thrust? 80g, 100g?

 scruffy1 39 points

i whacked it with a hammer (no, really !) - the shaft will slips required as long as you support the rest of the motor on the mount over an appropriately sized hole be gentle and it works fine - rustic but effective :)

 0Mica0 62 points

Yes, but you will have to use smaller prop (I'm using 4x2.5 prop with this motor on my MiniSwift).

 SunnyTurtle 20 points

Yes but the prop shaft is not long enough for the prop in wobbles if you try it. An the screws came out of the back because of the vibrations (in flight) Thank goodness the Mini swift is a good glider

 0Mica0 62 points

This one is not strong enough for AXN. It's much more smaller than default AXN motor. AXN spare motor product ID is AXN-2208-2150

 0Mica0 62 points

I've lost original grub screw and I replaced it with M2x6 screw

 RonRC 2112 points

Syamil, dunno about the pinion, but the shaft is 2mm and that is the size you will need to fit.

 Syamil17 24 points

Thx, also what about the wires? Does it come with the housing?

 RonRC 2112 points

Not exactly sure what you mean, but the wires are bare on the ends and you will have to put connectors on them. I used servo connectors so if the motor wasn't spinning in the correct direction, All I had to do was take the plug out and flip it to make it spin in the correct direction.

 Syamil17 24 points

Can I push the shaft to the other side of the motor? Also how long is the shaft? Can I use it on lama v4?

 RonRC 2112 points

Race, Yes it does. It's in the photo on the back of the motor. Loosen the set screw and it will come off to mount where you want it. You may want to drill the holes out a little so you can use screws that are easy to obtain. I used screws that were designed for sub-micro servos because they were the only ones that would fit. Hope this helps and Happy flying!

 Vionnet 1051 points

yes but not when you have an esc which is under 11A

 RonRC 2112 points

If you overload this motor with an ESC over 10A max, you will fry the motor. This tiny motor isn't rated for that much power. Good luck!

 comicflyer.de 279 points

Sorry! But... You can't overload a BL-motor with a ESC! You can only overload with a propeller. A Propeller is load, an ESC is no load. comicflyer.de

 RonRC 2112 points

coomic, correct, but if someone puts a larger ESC on, some may try larger props. Also, a larger ESC adds weight that isn't needed by such a small motor. Just trying to keep everything in perspective.. Ha ha! Take care.

 RonRC 2112 points

never mind.. I've tried them.. some were way out of balance and would not spin fast enough (without vibrating like a jackhammer) so it was a loss.

 nomedmon 38 points

i wired to 8 apm esc with solder light and clean

 scruffy1 39 points

there's a 3 pin female connector on the motor - but i don't know what it is called as an item

 RonRC 2112 points

A light easy way to make a three pin connector is to use male and female servo leads that will allow you to flip the connector over in order to reverse the rotation. Hope this helps!

 RonRC 2112 points

Please award the first person that sufficiently answered your question.

 Commander Clumsy 23 points

Hi Scruffy1 :) Mine came without the 3 pin connector, must be an older motor. Maybe you mean these? PRODUCT ID: 6pin M-plug.

 RonRC 2112 points

Commander, No, I was using JR servo end connectors. They work great with these little motors. That way, if it is turning in the wrong direction, all that must be done is take the plug out and flip it over.

 nomedmon 38 points

wow what a great way to connect small motor to esc RonRC, i would never think of that thanks for sharing

 RonRC 2112 points

nomedmon, Did you try it? I just leave the sleeve off of the side with the pins and use that for the motor side. Works great for these little motors.

 rapmoz 2 points

Sorry but I'm afraid it will burn after a few seconds but maybe its 5A esc will burn first!
these tiny outrunners are outstanding but designed for 2s lipo and 4025 props or slightly above.
For a fistful of GR more, the 11gr Turnigy 1811 Brushless will support a 6030 prop on 3s...Chris

 FrYakaTKoP 76 points

the c10 is save to GWS-5030 on 2s but i mostly fly 4540 for more speed, don't recommend run it on 3s get hot quick even on a 4025

 Derek 6 points

i have the micro 2000kv motor from the bixler and modded it with 6x4 prob, 14.8v and upgraded ESC, what is the maxx this motor can handle?, (new to flying and the numbers for things)

 con244 50 points

Don't think it is up to 1s applications. Very short flights would be the order on the day

 bz1mcr 233 points

It could be used with 1S. Remember a 2900 Kv motor on 1S will turn the same speed as a 1450 Kv motor on 2S. So you will need to use a larger prop. I would say start with a 5x3 and you could probably go to a 6X3 or 6X4 if needed.

Have Fun!

 RonRC 2112 points

Thanks, I know that with a 1S (3.7v) it should turn the shaft at (2900 x 3.7) 10,730, which should be fine for what I intend... a micro Extra 300 plane. I just didn't know if it would function under 7.4v.

 RonRC 2112 points

Hey, I just got this mounted to a small 3mm depron foamy I built. I'm using the Orange Spectrum micro receiver with the Hobby King XP 3A 1S ESC and 3 micro linear servos. I put a GWS 5x4 prop on it and spun it up to see how it pulled. I will pull it's weight vertical with a 1S 25c 350Mah battery. Now to get it in the air and get some video.

 RonRC 2112 points

Well Ladies and Gentlemen! I built a micro Extra 300 with 3mm depron and used a 4x3 prop powered by a 1S 350mAh battery and it will hover and pull out. I was very impressed with this motor's capabilities. The plane is a little nose heavy with the prop adapter, but I'm ordering prop savers that will lighten it up considerably.

 bz1mcr 233 points

Nice work! Are plans available? Can you post a link to the receiver and servos used?

 RonRC 2112 points

I can scan what I used. I only printed out a real Extra 300 on graph paper and then played connect the dots. Each square is 1/4" on the graph paper and I used it to scale up to my full 6mm depron size (39 1/2"). It flies like a dream and the small one flew well too... until it crashed. LOL.

 bz1mcr 233 points

What is span of this one "micro Extra 300 with 3mm depron and used a 4x3 prop powered by a 1S 350mAh battery and it will hover and pull out."
Also interested in howand where the gear was mounted and where carbon or wood dowel were used.

Can you post a link to the receiver and servos used?

 RonRC 2112 points

The wing span is 16" and the attached pdf if printed on graph paper is what I use to scale the foamy to. The red on this drawing are the modifications I added for strength, to protect the rudder, and to see some lines that were not very clear in the drawing I used. The CG is perfect on all models if set at 7/24 back from the leading edge of the wing. Set all control surfaces flat and it will be very easy to trim. Hope this helps

 RonRC 2112 points

 bz1mcr 233 points

Thanks for the drawing. CG at 7/24 of the chord? ==29%? Receiver? servo? location of gear?

 RonRC 2112 points

The receiver is the Orange spectrum micro 4ch. The servos kinda sucked so I'm getting the little HK-5320 micro servos to replace them. Also, I ordered some 2mm prop savers. These should be much lighter than the prop adapter I have on it (too heavy). For placement, I put the battery where I wanted it and checked to see where I could place servos, RX, and ESC using scotch tape to hold in place temporarily until I mounted them solid. After I rebuild it (when my local store gets more 3mm) I will upload some pics to show. The new servos should work much better I'm hoping. If you want to see one of my projects, go to YouTube and look up ron lampman and stopsign. Pretty funny. Take care brother.

 bz1mcr 233 points

Look forward to your pictures.
I purchased some of the 1.7 g HK single chip digital servos but was suprised to learn the connectors do not fit the ones on my Assan micro receiver. They are both small and white but the pin spaceing is just enough different that they are not interchangeable....***mer. I ordered one of the Orange receivers with small white connectors. I hope those match up to the new servos. I have a good supply of very light weight 2mm prop savers. If you can get me a shipping address I'll send you a couple.

 RonRC 2112 points

Thanks but I just ordered a bunch. I did order the male and female connectors for the Orange micro RX. I had to use one for the ESC only. Just found out my local hobby store will not be getting more 3mm depron until after the new year. Oh well...

 bz1mcr 233 points

Where did you find the connectors? I can't find them any where. Been looking!

 RonRC 2112 points

Here is what I www.link are on backorder now, but when they come in, get some.

 bz1mcr 233 points

links are getting blocked. If you use RCgroups send a PM or email to bz1mcr.

 RonRC 2112 points

Look up "Micro Servo Connector Lead 1.25 Pitch - Female Plug" on this site. These fit right in the Orange Micro 4ch RX.

 bz1mcr 233 points

Found them here Put wwwdothobbykingdotcom then "/hobbyking/store/uh_viewItem.asp?idproduct=19565"

 RonRC 2112 points

bz1mcr, my local hobby store finally got some more 3mm depron... Yeah! Now I'll build it again with SOLID depron instead of trying to piece it together. Photos to come.

 RonRC 2112 points

bz1mcr, I did a template of the micro Extra 300. When I printed it out, it was slightly smaller than the original, but not that much and it was proportional to the rest of the pdf. Interested? If so, write a question about it and I will answer with it.

 bz1mcr 233 points

The C-10 should be a good replacement for a 2600 Kv motor using a 2S 500 mAh battery. The C-10 will have slightly more power available.

 beilbyc 31 points

You need to give more info, this motor will most likely be too big for some micro models, you also need to look at the voltage, most micro run on signal cell batteries - I would be looking at A05 motors or 3.1gm motor designed to run on signal cell before using the C10.

 bz1mcr 233 points

 Rus 11 27 points

there is a 4mm in stock here, just go search for it and you will find it.

 CUEREL 1 points

Find what ever loose screw you got or just glue the thing- superglues good

 RonRC 2112 points

If you have a harbor freight in your area, they have a box of assorted set screws. one should be the right size. If not, try an automotive parts store, they may have it and if not they might be able to tell you the size and thread count of the missing set screw. Hope this helps!

 rchopper 78 points

opps C 10 comes with round mount.

 GooberSB 25 points

The shaft on the C10 motor is reversible. It comes from HK ready to be mounted in the back.

 AndyGray 97 points

I don't think this motor would last on 3s. It's quite a small motor, and I think you would find it would burn out on 3s. I have not tried it, but know it works well on 2s with a 5" folding prop.

 Alexander 5 points

i think no, take this prop (Turnigy Mini-Swift Replacement Folding Propeller & Spinner) My Multiplex Fox flight with 2 Zells super with this prop (ca. 5 A current)

 Jetsam 14 points

The C10 works best on 2S. I have found she overheats very quickly on 3S.

 GooberSB 25 points

It looks like a 3S with a 4025 prop is doable. That's very close to the max limit of 5A though. It seems like it is even slightly over-amped at WOT so I wouldn't go WOT with it at all. Maybe set the Tx to limit the throttle at 95 if you can.

 scruffy1 39 points

yep, i smoked mine on 3s :( shouldn't have pushed it with the gws5043 though... predictably it died (but it went vertical first)

 AndyGray 97 points

I would like to know as well actually. The shaft sticking out the front of the motor is actually quite short, and I think you would need a shaft adapter to mount a decent prop on this thing. The motor is equivalent to what is in the "mini swift" glider, but the prop for that wont fit this motor since the shaft is way shorter than what is in the motor of the "mini swift".

 Loopy 6 points

I took a prop saver from a Turnigy T1400 Brushless Indoor Motor 3000kv and drilled out the hole to fit. Works great. Now if I could just find more of the same prop savers like came with T1400 I would be happy.

 GooberSB 25 points

I think this would work for you PRODUCT ID: 019-00501-2M 2mm Prop Saver

 Todd 67 points

Search C10 prop saver. Or this link, www.link

 JustSomeGuy 9 points

Ive been wondering that myself. I was going to try a 6030 or a 7035 on 1s

 all4smallrc 12 points

Yes, but thrust will be extremely low. I would not recommend it. I tried it once, and the plane wouldn't even fly due to low thrust. You will need a higher kv motor for single cell use.

 Todd 67 points

Ditto to all4smallrc. For small props look at 7500kv to 10,000kv motors and 1cell.

 RonRC 2112 points

Yes it can, and with an Extra 300 with a 16" wing span, it will pull vertical on a 350mAh 1S.

 swessels 59 points

Hi, its about 17mm.

 znarfcram 92 points

17.88mm

 RonRC 2112 points

Specs says 18 and it's pretty close to that. Please give credit to the first person that sufficiently answered your question.
