Status: offline 		Probably about an 18x8.......Its a good place to start anyway.The Q35 is not a performance engine and you might as well go for easy starting,and smooth operation rather than try for every last RPM.....IMO.

Status: offline 		As mentioned, an 18x8 prop is among the acceptable prop sizes for this engine.

One thing that used to cause a lot of grief when the Quadra Q-35 was king was a lack of pitch in the props available in those days. It is easy to forget that these engines turn at roughly 1/2 the rpm of contemporary glow engines. As a result, many models met their demise because of a lack of airspeed. The engine/prop combination just wasn't up to the job.

My suggestion would be to try an 18x10 or 18x12. This will help move the model along a little faster. Don't forget to reset the carb's high speed needle for each prop selection, or you will not be happy with the results. It is a nice engine. Good luck.

Status: offline 		I have flown a Bud Nosen Citabria 1/4 scale with a Quadra 35. The props used were a Master 18-6, and a 18-8. I have also used a Zinger wood 18-6/10. This one has variable pitch and runs well as well.

My recommendations, if you want to run a plastic prop, the Master 18-8. For wood, the Zinger 18-6/10.

I am currently flying a Dynaflight Decathalon with a Quadra 35. Using a Master 18-8.

Status: offline 		canflynow, i had one of those giant hots. if it's the same plane you really want a 62 . a q-35 is no where near big enough. i had a q-42 in mine and it was a slug. my hots had a 8' wing. what size is yours? hope this helps , ron

Status: offline 		my hots had heavy alum. gear. it was like 3/16 thick . if your going to just putt around with your hots then a g-45 would be the least i would go for an engine. hope this helps , ron
