Hobby King Pitts Special Plug-n-Fly - 4 Aileron version (AUS Warehouse)
The HobbyKing Brushless Pitts Special is as exciting to look at as it is to fly! Its scale details complete with wheel pants and Pitts livery make it a very attractive plane, however the excitement doesnt stop there! This little foamie is equipped with 4 ailerons to give spirited aerobatic performance and the included oversize outrunner and 10x4.7 prop gives more than enough power for all aerobatic flight, and when you feel the need to turn it up a notch just switch the 10x4.7 for a 11x4.7 propeller for hovering capability! All this and still this little foamie is very controllable at slow speeds. This plane loves a walking speed fly-by. A combination of scale looks, excellent flight characteristics and great power plant make this fomie a real winner. The Pitts comes 97% pre-built and will take you around 10 minutes to attach the main wing and include your own receiver.
I've just assembled this great little biplane but fitting a 1300 3s battery is challenging to say the least!
I assume that it should be installed in the aft compartment ...... But it doesn't fit, do you need to start carving out this little beauty or can you install the battery vertically in the forward compartment?
What does this do the CoG if you do?
I put a 1300mAh 3S in the front compartment by inserting it vertically and aligning the widest side fore and aft. I insert it with the leads at the bottom (with the plane upside down) and then pull the leads up into the aft compartment to connect to the ESC. You might want to put a loop of tape around the battery so it's easier to pull it back out.
I thought the performance with the original motor was pretty lackluster so I installed the Donkey 1100kv. Wow, what an improvement. However, now I've gone one better and dropped in the Turnigy L3010C-1300kv (420w). This is almost a direct swap for the original DAT 700kv but you do have to swap the mount as the L3010C won't plug in to the original DAT mount. Anyway, at a claimed 1650gm of thrust the performance is absolutely spectacular! Take off is instant and it climbs straight up until out of sight. However, even with a 50amp ESC the 1300 3S was very hot at the end of the flight, even using low to medium throttle for half the flight.
I'd love to get this plane However will 2 soccer ovals be big enough to fly this plane?,Can you fly this plane on a 2200 mah batterie? and I can easily fly and land the hawksky however I'v never ever flown a aerobatic plane before, do you think I could fly this plane
I use the 1500 Zippy compact. the weight is perfect for the CoG. It is a snug fit. (remove the stickers from the sides) but they do go in. Keeps them in place during the flight. Try and stay within those specs. i.e. size and weight and you will have no problems
ive never flown planes before, this plane handles so well and has enough power that i was able to prevent a stall even when i accidently sent the plane vertical after launching.
on my second attempt i even did a stunt! i performed a roll. great plane can fly slow or fast
ESCs …* Faulty Manufacturing Hobby King 2*10A ESC (Blue Heat Shrink wrapper).
Be warned! The ESC that came with my Pitts special failed upon about the fifth or six power up! It burned up the motor windings as well. At the time, I didn't know whether it was the ESC or a faulty motor, so I swapped it into a working motor circuit and burned that motor out as well! (Duh !! .. oh well .. 'twas a 50/50 bet 'test' at the time ..)
The culprit? Upon a microscopic post mortem of the "Hobby King 2*10A ESC", I noticed two big blobs of solder splashover bridging two tracks on the middle row of the "65PO3 1BG2G" power FETS(?). Not much wonder .. the surprise is that it worked at all (the few times that it did work) ...
Beware these ESCs!
I notice my problem is shared with another on this discussion list.
Love this plane! Firstly added a second servo for the Ailerons, running the throws as far as it will let me! Also added a 20 amp speedy and a Turnigy Park480 Brushless Outrunner 1020kv(1300mah 3s). Fantastic fun! Great fun to fly, knife edge, loops and rolls really well. I would buy another.
I swapped out the original motor for a Donkey 1100 and put in the HK 50amp ESC. I had to make up a 3/8" plywood motor mount which attaches to the original plastic mount. Then the Donkey easily screws to the plywood mount and spacing is perfect for the cowling. Running an 11x4.7 prop and 1000 - 1300 mAh 3S pack. Performance is absolutely phenominal but set your timer for max of 4.5 minutes on 1300 pack.
Since writing the last reply I've stacked my Pitts and stuffed the Donkey. FrankenPitts is flying again but with the original DAT 750 motor...ho hum. However, I've found another replacement...Turnigy L3010C-1300kv (420w), available from Int Warehouse. This thing supposedly puts out an unbelievable 1650gm of thrust!! And it is a direct drop in for the DAT 750 but you will need a 50-60Amp ESC. I'll write more once it arrives and I do a test flight.
My final configuration is Turnigy L3010C-1300kv (420w) spinning an 11x4.7 prop, 50amp ESC, and NanoTech 1300mAh 3S 45/90C. Performance is absolutely spectacular! Take off is instant and it climbs straight up until out of sight. You can hover on 1/2 throttle. The Nano doesn't get hot.
This motor is almost a direct swap for the original DAT 700kv but you do have to install the supplied mount as the L3010C won't plug in to the original DAT mount.
If you want absolutely blistering performance go for it.
Nice plane, but mine came with no instructions. Is there supposed to be any? I really only have two questions right now, where's the CG supposed to be? And where do the two little thumbscrews go? Through the small holes in upper inter-plane strut mount points? Also can I assume the throws are correct for the flight surfaces?
The thumbscrews go where you thought they should. The CoG is approx 10mm ahead of the rear wing bolt [top wing]. As for the throws, I have flown 2 Pitts' before [ic power] and they do not need a lot of throw. They can be twitchy little devils so keeep it soft until you work it out.
Have just test flown my Au pitts.with the battery as designed it flew fine but needed slight down trim.Building without plans straight forward.I could not find C of G details except the blogs on the U.S. version referred to same aircraft different brand with c of g hints.
Matthew you have had a lot of help but still you have not credit any one. Any how the manual can be found under the heading FILES. Just down load then and print. This is the way Hobby King does it half of there planes. I hope this helps
Here's something else that isn't obvious...before you install the landing gear look at the flat tabs at the top of each white plastic V panel. There is a piece of white tape on each which is pretty much invisible. Peel off the tape and it leave a sticky surface on the tabs for attaching to the fuselage. And no, it doesn't work very well anyway.
2*10A ESC lasted less than a day. Suggest you buy another 20A ESC with this plane as a backup. Otherwise, it is a really good looking model.

For only $106 delivered in 4 days, how could I not give this little beauty 5 stars. This plane is actually very nearly perfect out of the box with very few mods required. One modification I would recommend is to cut around the single aileron servo and replace it with 2 of the legendary HXT900 servos so each servo drives 2 ailerons- 4 ailerons is a lot of aileron for one little 9G servo so go for 2. For my maiden flight I used a 1800mAh battery I had handy which fitted vertically into the front compartment. I fitted the receiver into the second compartment. That first flight was less than impressive the plane was sluggish and appeared nose heavy and struggled to loop. I purchased the Turnigy 1600mah 30C 3S packs which were about 20grams lighter. They are a tight fit inserted flat so don’t forget to tie the ribbon around them so you can drag them out. To move some weight back I carved away some foam such that I could angle the battery from the front hatch towards the back thus moving some weight back to push the COG back. The other mandatory change is to a 10 x 7 TGY Slow Fly prop and this gives realistic scale aerobatic performance (not 3D). No additional weight required anywhere. With these mods this plane is a gem with no bad tendencies whatsoever - you could consider it as a scale Acro advanced trainer. Note on my maiden flight I set the dual rates switch to low for ailerons

I wrote a review last week on arrival of the Pitts, since then I have assembled and flown it, I purchased a smaller 3C 1300 Battery (from local H/Shop) to fit as it would take too much butchering to get the Turnigy in and I think the front Battery housing is kind of useless, if you put anything in there it just falls through and more mods would be necessary.
I was concerned about the quality of some of the parts and I still stand by that, two of the aileron clips broke off in my hand with hardly any pressure, the undercarriage is pretty weak.
Anyhow the proof is in the flying, so with what I think are the best throws needed and an unknown CofG off she went, it was obvious pretty quick that the tail was too heavy so I got it down quick with no damage, I added about 6oz of weight to the nose and off again (CofG now 25pcnt in top wing), I did a few circuits, rolls, loops etc and surprise surprise it was great... in the air it looks quite authentic and the chequered decals work well, I used the standard setup prop etc.. it took off from the ground well and flew scale like.
I have purchased other props and will experiment (as per other reviews), anyhow second flight and I had hardly any aileron so brought it back into land and found one of the aileron wires had come astray inside, so make sure you put tape or something to stop them coming apart.
So finally my verdict is,

Received mine five days after ordering. Was double boxed and well protected. Will assemble then go for the maiden flight. Only issue I see is the battery suggested does not fit in the compartment. Oh and no assemble instructions. Will write again after first flight.

Flew mine today for the first time and all i can say is what a hoot, is a little tail heavy but i'll some how jam a bigger battery in there to fix that. All in all the best 100 bucks i've spent lately, incidently this is my first foamie coming from a glow backgound, glad i made the change.
