What I really want for a 3696 motor
A full power motor that runs right around 9K without resetting the ATV/end points to 36% on an 8C battery
<ul><li>for singles on a 9x6 gas prop </li><li>for twins on a 7x6 gas prop </li>
</ul>
Looking for suggestions/recommendations

Ed, the motor I run in the Brewster and Bearcat is the Electrifly 35-36-1000. I'ts rated at 40 amps constant with a 53 amp surge, but I'm pulling a bit less than 16 amps at 8900-9000 rpm, with no limiting of the ATV or subtrims. So far the motor has landed cool every time. It's a bit pricier than the 2908, but it's an Electrifly product, and it comes with a nicely made cross mount and a good prop adapter that is 1/4-20 thread. The motor shaft is 4mm...been good so far!!

Ed, I will let you know what an Eflite 10 will do after I get it in.
My 2908 tossed a front bearing on my 1st flight [:(]
It was a funny sound at full power, checked the shaft and clearance. Looked OK.......
Reflew this AM, not so it was the bearing.
So with some luck from FedEX and Horizon should have it before this weekend and will give you the data after its installed.

<br />I would contact the motor supplier and see if they will exchange the motor for you. I have had good experience with mine, other than the fiddly bits with the power settings.

I did email rchotdeals and they are shipping me a NEW one.
Just have too send the old back. Im just leary about the 1st run.
As for my power settings the only time I have had problems before was with A 20amp Caslte creation. It would drop the programing,and I would have too reset it on the PC link.
Other wise no problem so far with my ESC or motor settings

I don`t have a problem with the 2908`s either when used with the Tower Pro ESC, but some folks don`t like to use their computer options on their radios. Or they don`t have them. For a class that dictates a specific rpm, you either have to use the radio to set the rpm, or fly a little back of the max by playing with gear ratios and such. Talk about diddleing, gear boxes are diddleing.

I re-mounted the NEW 2908 today after weighing the difference of the E10........
The E10 is heavier and the mount was different.
Stuck with the 2908 and re flew this afternoon.........[:D]
The STANG flew well.....not much for inverted flight but I can add some down throw for that.
Here I can fly at HALF stick and NO probs. or just PUNCH it too FULL and go vertical.........[}:)]
I rechecked the tach and is holding 9K with a slight drop.
Amp pull is low , the batt was barely warm........... after a 5 minute flight.
This NEW motor sounds so much better than the 1st one.
A side note is the E10 is heavier and a touch longer in the case.
ps : My EPA is set at 18 % too cool plenty of power too play when not in combat.......only with the correct C rating on the batt, of course.

Good report. Glad the new motor is working well. I felt bad that you had probs with the first one. All of mine have been great.
That is one nice thing about the 2908, you do have to dial it back, but with better 3s batts, you can really hot rod if you want to. With a lower kv motor, you are stuck at 9k no matter what you do. You can go with an 8/8 prop or something like that, but rpm will get you speed every time.
