Has any one compared the 2 motors the Mega And the Aon 3500 in flight ,for performance, flight times and heat build up of the motor and battary????
trex tuning did bench testing but i would like to here from some of you that have actually tryed both motors.

Thank you for the help on this.

for 11T pinion
I have the following motors:
ACn16/15/3
V2815@3500
V2815@3000

I flew all three in the same Trex, stock woodies, ccpm, 11tooth pinion on 3S1P packs of 1800, 2000, 2100 from Dymond and a 2100 from Polyquest.
CC25 controller in fixed throttle mode, no-current limiting

The 3500 AON is the rocket of the bunch and everything is cool~warm
The 3000 AON is a cruising motor, didn 't measure it but it seems to get a minute or two more flight time. I am currently using this motor in the governor mode.
The Mega ran the warmest, but that was many flights ago. At that time I was just getting use to my Trex, and as such I was hovering most of the time. The last two are definitely less powerful than my friend's 400DH@ 8T pinion. But the 3500 kV Aon seems stronger than the 400DH.

I didn't bother to try, all the possible pinion combinations as my motors all had 3.2mm shafts, I could not try the 10T pinion. I was also too lazy to try a 13T on the 3000kV AON nor the Mega. For my non 3D type of flying, perhaps the best comprimise motor is something with a kV between the two, ie about 3250 rpm/V ? I am now curious about the Astroflight 803T ?

Have you looked into it ? Have you also looked a the the threads talking about the new Aurora 480TX motor ?

I hope my ramblings are of help.
For the money I would say the AON 3500 kV motor with the heatsink is the best deal. Some say that the 3000 rpm/V AON is best on 4S, but I want to stay with 3S packs. Who knows, perhaps the Neu motor or the Mega 3T and AON 3000kV motors might be in a completely different class when on 4S ?
Perhaps, if you are starting heli's the lower kV motors would be good to start with, and then progress to 4S packs when you need more power ?

Well thank you for the info , i ended up buying the AON 3500 the only real issue i see is flight times seem to be shorter then the other motors. does it matter much if you are hoovering around vs flying 3d as far as flight times???
Thank you Marke

I have the Aon 3500 and get 12-13 minute flights mostly hovering.

Astroflight has a new motor specially designed for the T-Rex. Ten minutes of 3D flying is typical. The motor has gobs of power and runs fairly cool. Try it and you'll like it.

flipflyer do you have one ?
Flipflyer:
Do you have one ? What pinion are you using ? What esc setup are you using ? Fixed endpoint throttle or governor mode ? what HS are you running at hover and during a climbout, max pitch ? Lastly, AUW of your set up ?

Sorry for all the questions.

Yes, I do. The thing climbs out like a 30 on 315MM blades. Walt Ferar has one on his T-Rex and to watch him do 3D is just amazing. I'm talking the whole routine including continues flips with the motor hardly slowing down. Just about everyone in our club that have a Trex has switch to the Astroflight motor. The motor cost about 90 bucks but you can use the Align controller which is not as expensive as the CC.
