What a cool little engine. I've posted the figures for my ST G20 .23 for comparison. I thought this one was strong.
HB PDP .21
Temp: 51°
Powermaster GMA 5/22
Fox Short R/C plug
APC 9x4:
13,562
3.13 lbs. static thrust
.42hp
And...
Super Tigre G20 .23
APC 9x4:
12,768
2.55 lbs. static thrust
0.35hp
I guess PDP is for real.
