Beleive it or not, the PT models props are right in line with wood props for weight, I think the 22X8 is something like 4 ounces before drilling. I'll bring one for you to try out. At such a low oil ratio at 90 or 100 to one, you definitely do not want to load the engine too much during breakin. Oil is most of the cooling the engine gets.

the Cap is the Great Planes 27% with a DA50 with over 200 flights now and the Yak is the Aeroworks 50cc Quick Build with some custom graphics from BadBradGraphics at right at 100 flights.

I gave the Aerotech one away as I could not stand it. It had way too many issues. If you think back I had given it to whaturi and he tore all the covering off of it, repaired the incidence problems and installed a MVVS58cc and then promptly got it too fast and fluttered it to little bitty pieces.

The Yak is powered by a 3W55i on a header and KS tuned pipe at 18.75lbs minus the smoke system I'm installing. It's got JR8611's everywhere.

Here is what I will bring to help you out with, we may not need them all but ya never know.

PT Models 22X8 predrilled for the DA50
New spark plug
Carb gasket kit
Infrared temp guage
Fuel at 50:1 using Motul 800. This fuel mix leaves not mess at all and keeps the engines at a nice 175 degrees.

I got away from 100:1 for both the Da and 3W engines since I fly mine pretty hard and was seeing temps in the 220 degree ranges with the needles set correctly.

Don't worry, we'll get it running good for you
