Going through my old video's and came across one taken back in 2005. I've been heavy into fast edf's and pylon racers, but still haven't beat my DS PB at 212mph. Nothing beats the rush from Dynamic Soaring! Sorry for the terrible video.

opus 212 mph (0 min 48 sec)

Almost ready for maiden.

AUW around 12lbs (used cheap fish scale)
Stumax 110-45
Neu 1524/1.5y
CC160hv Medium timing
Gens Ace 30c 12s 5300
A123 rx pack. No regulator. No switches.
Airpower electronic valves for retracts and brakes.
CG 150mm

Full throttle static results with 82mm exhaust diameter:
6375 watts peak. 6kw after 5sec. 5.8kw after 10sec.
Gens Ace pack holds at 44.4v (3.7v/cell) at 131 amps.
CC160hv with cooling fan peaks at 137F after six 10 second runs with 20 seconds breaks between each run at half throttle. Used 3000 mah.

I used a large 5v cooling fan on the controller to avoid cutting vents in the plane. It seems to be doing a good job and only weighs .5 ounces. While running, I can feel the air exit out the tail of the plane. In the air, it should run even cooler. I'm shopping for a non LED fan as this one is obnoxiously bright.

Speed was the focus of this build and I believe I chose the right fan for the task. Hoping to maiden in a week or so. I'll try to get video and radar.

Powered by Neu 1512/2y, 10s 5000, TJ100 fan, CC110. This is a 3200 watt setup drawing 87 amps. Considering going to 11s and run controller on low timing.

Motor temping at 94F on 10s.

Highest motor temp is 100F so far. Wondering how much I can trust this tepm probe. Switching from 10s 5000 to 11s 5800 soon. Hope it cg's ok.

1kw setup is good for mid 170's.

1.16kw goes 180 even (Neu 1115/1Y 4s 5.2x5.2 graupner, 60F ambient)

1.3kw goes mid to high 180's (ARC 28-58-1 on 4s)

1.55 kw goes low to mid 190's (Neu 1112 2.5d on 5s) Fried controller on hot day


Fried the cc80 pushing the Arc 1300watt setup hard on a hot day. Didn't competely fail, just cogs at high rpm.

Swapped the ARC 28-58-1 and put in a Neu 1115 1Y. Both are same size, Neu heavier and lower kv. Neu motor draws around 82amps 1160 watts at 65F room temp on 4.75x4.75

update: 1115/1y
Warmer weather really increases battery performance. This setup pulls 87 amps 1300 watts on a warm day. Identical performance to the higher kv arc motor. I Puffed the 4s 3000 pack and motor hit 200F. I guess I won't be going to 5s. Maybe during winter.

Update: 1115/1y Rhino 4s
Got some graupner props in. 4.7x4.7 draws same as apc at 65F room temp around 82 amps static around 1160 watts.

5.2x5.2 draws 87 amps, but the rhino 3700 25c pack sags heavily down to 3.3v/cell after several seconds at full throttle. Resulting in similar wattage to the 4.7 prop around 1160 watts.

Update: 1115/1y Rhino 4s
5.2x5.2 does consistent level laps at 179-180mph. Ambient temp was 60F and wattmeter showed 87amps 1200 watts after 5second burst. Watts were still dropping. Probably would have leveled off at mid 1100's like previous test. Very easy to launch at half throttle. Tons of thrust.

Latest plane is a funjet fully glassed. 5s 3000 on Arc 2t makes for a great setup. Good speed with lots of runtime on 6x4 prop. Very fun to fly.

Clocked it at 127mph today on the 6x4 which draws 1kw.
