I've seen reference to APC 7x4, 6x5.5, and 6x6 props for E36.  Has anyone done a comparison of climb performance?  I'm using a Cobra 2203/28.

Neil, it really depends on the motor you're using. The Cobra motor you mention is the same I'm using on my MUTT E36. Finished 5th at this years nats. using an APCE 6 X 4 prop. My new MUTT II (increased wing area) is pwr'd by a drone racing motor with quite a bit more torque and I'm flying it with an APCE 6 x 5.5 prop. On it's first competition is took first place. I think the 6 x 5.5 will work on the Cobra motor but it's been my experience that on the lower torque motors that you get more for the buck with a smaller prop turning more rpm's.

Thanks Scott.  I was thinking along similar lines. By the way, how did your electric Geef work out?

Hi Neil,

I have compared various props and got the best climb with a 6 x 5.5 on my E-36 Maverick with the 2203/2800 Cobra. Graphs in the thread somewhere below.

Thanks Paul.  I looked at your thread and am very impressed by your performance.  I'm not sure whether I will achieve your low weight but it's a goal.  I am building a BMJR Witch Hawk E-36.
