Hi all. I would like to get anyone's input on the size prop I should use.

Global Freestyle
10cc or .61 Webra
6 lbs.flying weight

I would like to be able to hover in the least. Not necessarilly after speed. Any help is appreciated. thanks

I have a Webra 61 on my clipped wing GP Trainer 60. (Not to be confused with a 60 size trainer. ) I run a 12x6 APC. With a tuned pipe and 15% CoolPower it turns 13,400 rpm. My Webra is an older version that takes a strap on muffler. Not sure about the new ones.

Thanks Deputy,
I am running a 12/8 on mine. My engine is the "old" Webra 10cc.
I noticed today though that in climbing, engine seems to bog down. Thought it was too lean and richened it , but it didn't seem to help. Any suggestions on maybe installing a pump or pipe?
It takes the strap on muffler also. Right now using a straight muffler. It seems to me to be fuel or adjustment problem. Any thoughts ?

Don't know about the pump, never used one. I have a Macs header and pipe on mine and it increased the power a good bit. I don't remember how much of an increase I got with the pipe. My suggestion is start by trying a little less prop. The 12x8 may be too much. The Webra likes to turn high rpms.

Thanks for the suggestion. I was getting 7.5 #'s of thrust with a 11/6 . May try that again. What is your input on using this engine with a 56" Global Freestyle 3-D . Weighs in around 6 #'s. Thanks again.

I know nothing about that plane but my Webra is on a plane that weighs about the same and I love it. This Webra is one of my favorite engines.

What do you guys think about the APC 12.25 X 3.75 for your webra? I used it on my ST .61 w/bris muff on a H9 Cap 232 and the motor really liked it and I was able to at least hover it. No major pull out power. But it did improve vertical and hovering.
