Trex with stretch boom and Align "Carbon" blades.
AON 3500 11 tooth pinion
CC 35 esc
TP 3s 2100
GY240
Hitec HS56 X 3
Futaba 3108 on tail

Prior to this motor I tried the Align 400s, Chili 3200, and Mega 1615-3. The Mega was close but still got too hot. The AON is only warm after a flight.

From reading on RR I guess I'll buy a Lehner 1020/17.
500 watt/ 750 grams.....

Himax 2815-3000 13 tooth pinion
Phoenix 25
Kokam 2000mah 15C

I am very happy with this combo, I ran a Himax 2025-4200 from my Shogun before this motor (weak). Now the climb out is comparable to my sceadu/hyper 50. The Kokam 2000s never get over 94 degrees and the motor runs 120's with a heat sink. My head spead with the 13t pinion is 2500 rpm on the ground in idle 1 and it maintains very well during extended climbouts. I would highly recommend this combo. The motor costs $79 and comes with the the male connectors already soldered on and you also get the female connectors for your speed control. This motor has a 3.17 inch shaft so you can use the 13t pinion that comes with the T-rex kit. :glasses2:
I run fixed throttle mode, idle 1 throttle curve 90-80-75-80-90. Idle 2 90-90-90-90-90.

929pilot- do you know the current draw on this setup?

[929pilot]

mudbogger- No, I set my timer for 6 minutes, when it goes off I usually do one or two more things and land. When I charge the pack with my Triton it takes 1300 to 1370 mah. Considering the temps I'm getting this setup will last a long time. If I'm using 1370mah in 6 minutes wouldn't that be like averaging 13.7 amps? According to himax this motor requires a 25 amp controller.

Before I put on the heat sink I was getting 145 degrees with it on I'm getting 124. The battery has never reached 100.

I think a large key to the perforance is the battery pack (Kokam 2000-15C). When I tried my old packs (Kokam 1500-6 or 8C) the performance drops off big time and the pack gets hot. When I first used the 2000-15C pack with the 2025-4200 motor it helped alot but when I install the 2815-3000 I new my search was over. :shock:

Tower sells this pack with the deans plug on it for $68.99. It flies great but won't fit in the canopy unless you lose the servo frame by going ccpm.

My Kokam will go under the servo frame but not through the sides of the frame. I can get my canopy on.
