If i used two of these motors, would it work for an 800mm boat
 ShamrinHM 504 points
Yup it will work but it will be too much work for the motor with this size(small) on 800mm boat..possibly it will not last longer too..normally people will use 36mm size motor on that size of boat..

sorry ross but what prop do you use in you boat? thanks for the info!
 Ross 23 points
No worries. The impeller in the jet unit is 20mm diameter. This motor could run a 30-35mm prop. That would be the maximum I would run in a boat that size with this motor.
bingen  3 points - 5/6/2013
 
what ESC would you reccomend me if i want to run my boat of 500mm large with 2S lipos? and how many Cs of the lipo?
thanks
 Ross 23 points
I use the 50A birdy water cooled esc. I have run the same motor in a 500mm home made Jetboat with the 50A Esc and it runs really well. Read the reviews on the esc before buying, I here many have had their esc burn out. However I have 2 that are still running realy good. I have tyed both 2 cell and 3 cell. 2 cell run better in a jet boat, but there is a hell more power on the 3. hope this has helped. Cheers.

Would this work as a replacement motor on a the HK centurion??
 ShamrinHM 504 points
Yes it is, same specs as stock Centurion's motor, just different on kv tho..hope this help.
Hayden  1 points - 4/24/2013
 
Is this a good replacement motor that does not need any modifications for the HK small bolt? thanks
 waterlogged 2280 points
This little motor really screams and would be a good motor for your boat. Just be careful fitting the cooling hoses. If you put too much pressure on the especially sideways they will snap. Try soaking your hose end in hot water before fitting. It will just slide on easily.

Would this motor fit directly to the NQD rc jet boats stock coupler, or would you have to drill it out?
 ShamrinHM 504 points
Im not sure about the NQD Jet, but i read some forum about it and saw there is someone using these motors on it..may be it suited/fitted the stock coupler since these BL motor has the smallest shaft diameter in the market as far as i know. Hope this help.
 Ross 23 points
Yes, the orignal srews, and coupling fit staight up. I have run it in three of the NQD boats and it is prefect. May vibrate alittle, all of mine seem to. Hope this helps.

Hey sharim , i think i have esc issues it starts very fast and quits an then you hear the beeps as the motor or esc resetting it had a hk 30 amps esc do you think im falling short of amperage or i still have programming issues it does not quit while not under load
 ShamrinHM 504 points
Hye Bryan, my esc behaved like yours too..my boat suddently stop like the Rx dosen't received any signal from the Tx and the motor beeping a lot..i tried with new Rx and even another Tx and still the same..may be this is the bad things about that esc..
 ShamrinHM 504 points
Btw, if i were you i will use these esc PRODUCT ID: TR-M-35A very reliable, waterproof and very easy to programmed and it has reverse too..i have these on my Centurion mini..
 waterlogged 2280 points
The ESC could be cutting out due to overheating. Try increasing the water intake by fitting a transom intake. I've seen a piece of copper tubing and even a piece of carbon fiber pipe cut a 45 degrees and epoxied to the transom to pick up water. Run the two intakes through a T piece and always go through the ESC first then into the motor then over the side. Make sure you wire tie the hose fittings to stop blow out from pressure.

Well thank you got it programmed I think but I have to reverse the polarity on the wires cause it runs backwards of the prop and I soldered the wires :(
 ShamrinHM 504 points
Glad to hear that, good for you, you soldered the 3 wires? hehe..normally we use the connectors and for these it is 3.5mm..anyway have a nice day and good luck.

So basically when it stops beeping I'll should let go the throttle ??
 ShamrinHM 504 points
Hi Bryan, Sorry for my poor explainations below..How is you doing now?
bryan  2 points - 4/15/2013
 
What then Sharim it keeps beeping will it ever ? When do I let go the trigger ? How do I know is ready ? I. Used to the old school electronics on rc sorry man thanks for the help by the way I'm in puerto Rico where r you give me your e mail so I can post a picture iPad won't let me post it here for some reason
 ShamrinHM 504 points
Once you let go the trigger it will enter to the program options, this will be difficult..just change the 1st options only so that your esc can responded to all..
after the single tones let the trigger go and you will hear another tones, Then put ther trigger on Full Speed again after another single tones.
THEN SWITCH off the TX
 ShamrinHM 504 points
Disconnect your lipo and esc, then
try Reconnect it again, it should be bound already..
Hope everything alright. Good luck pal.
bryan  2 points - 4/15/2013
 
Sharim I'm stuck with the programming how do I do it can't get the instrucctions they r not on the web can you give me a basic set up with the control peaseeee heeeeeellllpp. Thank you
 ShamrinHM 504 points
Sorry to hear that pal, anyway basic programming is using Tx/Controller..my steps as below:-
1- Connect your Motor to the Esc
2- Switch ON you Tx and put/push your trigger on FULL SPEED
3- Then Connect your Esc and Lipo together
BEST ANSWER CREDIT AWARDED
 ShamrinHM 504 points
Make sure your Trigger still at full speed after these 3 steps..
After that, you can hear programming tones..after 3 musical tones, there will be another tones (optional tones, 5/6 different tones)
If i were you i will only change the 1st setting, which is Movement (forward and reverse options),
 ShamrinHM 504 points
Wait pal, there is still another steps, i need to type it step by step..to make it simple, try download manual from Turnigy Marine ESC on a File Tab, from there you will get what i mean.
bryan  2 points - 4/14/2013
 
Also have to play with the wires if I hit forward it I'll go the other way at least against the prop an vise versa
 ShamrinHM 504 points
Yup, you are right..need to play with the 3 wires and just make sure when you hit forward your boat/motor move forward too..hehe..anyway, have a nice day and happy boating.
bryan  2 points - 4/14/2013
 
Sharim just got around installing everything on the miss geico 17 just got a couple of questions got a hk item number 9261000008 esc and bought an octura 427 prop , regarding the esc if you hit reverse I will keep running on reverse until you hit forward is this normal
 ShamrinHM 504 points
Regarding the HK esc, i owned the 50A version and it's hard to understand the programming and i just change the running mode. Anyway, how did you programmed your esc? Make sure to use only 25% Reverse Force only.
ramon  1 points - 4/10/2013
 
can u put this in a miss geico 29 cat and how fast will it go?
 ShamrinHM 504 points
MG29 with these motor is way too small..you should look for 36mm or bigger so that you can play with the prop size and get better speed..these motor cannot handle bigger prop tho..hope this help..
bryan  2 points - 4/4/2013
 
Sharim nh might be a dumb question but will this prop fit the factory shaft
 ShamrinHM 504 points
Do not worry about the stock MG17 shaft..fyi i owned the MG 24" version and it has 3.17mm prop shaft..im sure the 17" version has the same or slightly smaller diameter too..if smaller, you just need to put shrink tube on the prop shaft for adaptor..Hope you get me..

I put it in a redbird hull from H&M with 2S LiFe and it go very fast. With a 2 lipo it can go more than 50 km/h !
The cooling is very effective an with a k29 the motor is cold.
I have more than 10 min of run with 2300 LiFe.
Je l'ais mis dans une coque de Redbird de H&M
avec un pack de 2s Life et il va trs vite !!
Avec un lipo je peu aller plus que 50 km/h.
Le refroidissement est efficace.
J'ai plus de 10 min d'autonomie avec un 2300 mA.

The given engine is ideally suited for boats ECO mini. Never use without water cooling. Use a propeller of 25-28 mm.

Wow, this is the most ideal motor for a nice micro boat build!

I tested this with 7.4v 1800 mah lipos and a 25 amp speed control and it rocked! super fast and consistand power.

I got 50 watts at 8.2 amps and lots of thrust.

The motor got a bit warm with the 30mm prop and 6 cells but with 27mm and 3 lipoly, it should run cooler and higher RMP at the motor shaft.

Lots of applications for this motor at this price.

The runs really smooth.

I highly recommend this motor for weight saving and very good power to weight ratio output.
