My motor and battery seems to get too hot after a full flight. My tp2100 got way too hot just flying the rex at about 60% throttle and full power for a split sec.. I didn't notice the hot temp because it was kinda chilly outside when i was testing out the motor for the very first time. Not what i expected. Im thinking the problem might be because im still using auto calibrate mode and not using gov. Where should the timing be set at? High or low?

Is it me but the aon motor seems to have very little clog. I can spin the shaft by hand. is this normal?

run it in fixed pitch mode or governor mode. In auto calibration mode the esc will see 60% as full throttle if that is the most you increase it to....

I always thought that should be normal in a motor? All the brushless motors I've had you can spin the shaft of the motor and it moves smoothly and easily. The AON especially so. I think a motor with "clog" would not be a good thing?

Like richie1967_uk says don't use the Auto Calibrate mode.

Cheers

I used auto calibrate on the 400sf motor before and it worked fine. The align 400sf had some clog and was hard to turn by hand.

I would try the Fixed Throttle mode and see if that helps your situation. My AONs don't overheat at all. I use Governor High mode and it works great for me. I've read that Governor Low is the correct setting for these motors but it hasn't worked for me so far so I've stuck with high. I also use the High Advance.

My understanding of electric motors is that there should be no binding or "clogging". They should spin nice and freely in your hand. When you say "clog" do you mean with the motor out of the heli and you spin it by hand or when the motor is installed and you spin the rotor head with all the drive train engaged? Just want to confirm.

I have noticed with my align 400S that it doesn't turn anywhere near as smoothly as the AON outside of the heli, you can certainly feel a little resistance every half turn but I do believe that is normal for the align motor. I still can't believe I threaded those screws in so far as to cause damage to my aon motor! and now it's been so nice and sunny out! it's terrible I tell ya...

Hey Mark
aon sells just the mounting plate by itself so you can replace it. It's like only 7 bucks.

The motor is easy to turn by hand when the motor is out of the heli. I guess htis is due to the motor being an inrunner motor. My friend has a 400dh and its hard to turn by hand. Well I think this is normal now.

Going to try the motor in gov when i get home today.

Ok just tried the aon in fix mode and I don't like it too much. The motor doesn't spin till the stick is almost half way up. I trim out the throttle so now it's working perfect in idle 1 (set at 0-65-85) but then in idle 2 the motor has plenty of power at top stick and not enough power at low stick (set at 80-70-80)
Im still getting the heat problem. I found out that the motor should run at about 60% headspeed. Anything over that the motor and batts get hot. I also reduce my pitch at half stick and now the motor runs a lil cooler but it's still hot since i can only hold my finger on it for about 4 seconds. Im not really happy with this motor right now. Should I need to upgrade my CC25? I still have to try gov mode but with the current setup heat shouldn't be a problem. I wonder if the pitch is the problem. Maybe I have too much pitch. Is +12 too much?
One more question now with the new aon my tail sometimes doesn't hold when i punch it full power. Must be the pitch huh?

I am starting to miss my old align 400sf motor. Seems like with the 400sf motor the head speed was way up but than it didn't have that much torque. Im not saying the aon is a bad motor but the heat problem is getting to me.I think the aon has too much power. I can give 80% throttle at -9 degrees and I can't hear the motor bog down.

TonyTypeS,

Don't know what to suggest. I'm sure someone else will read this and have some suggestions. You may have to fool around with your pitch and throttle curves a bit.

I know with my CC35 in Governor High with the end points adjusted correctly I can run my motor at around 80% to get a nice flyable headspeed and my motor and battery are not too hot, that's using an 11T pinion.

As far as your tail not holding mine does that as well if I punch it. Just for a second though and I can usually anticipate it and give the necessary correction. I think it's just a matter of the gyro catching up to the increase in rotor pitch and engine speed?

I know it gets frustrating and because everyone runs different setups it's hard to just give a fixed method to make everything work. It's a lot of experimenting and adjusting.

Hopefully you get it sorted out soon and can enjoy some flying.

what pinion ?
My experience has been very good with the 11T pinion. I find that it ran warm~hot when I had a linear pitch curve, and after getting the throttle position higher up, like 80% on my CC25 it ran just barely warm. I also use their heatsink and don't fly with a canopy. I think that it ran more efficiently at a higher rpm atleast with my CC25 in the fixed mode.
