RE: Honda GX-31 and Giant Eindekker??

Try a heavier nylon prop, mine runs better, higher revs and better low end with a cheap heavy prop.

My GX31 is going in a 1/4 scale SE5a I'm in the process of building.

RE: Briggs and Stratton 34cc Fource?

I have a vid of my Honda GX31 in a 91" Volksplane, prop was a 20 X 8 Menz but it appears to prefer heavy nylon props so I expect to get more pull from it once I get some other props to try.

RE: 1/4 scale SE5a Wing Loading

I would imagine you have plenty of power, I flew the DB 1/4 scale with a Zenoah 22cc which had adequate power. I'm planning on building another and fitting a Honda GX31cc fourstroke petrol.

RE: Honda GX-31 and Giant Eindekker??
