Default Hot! HB PDP .21

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.

I'm using Pe's spreadsheet:

If you don't have Excel, you can use OpenOffice like I do:

http://www.openoffice.org/

It's 100% free open source software and does everything Microsoft Office does.

Thanks Dave, I have Pe's software also. I was just wondering if you had something else I could play with.
