Zenoah 20EI Engine Speed
My project of putting a Zenoah 20EI into a Blitz Avro (600-620mm blades, shortened boom, new side frames, bottom plate) is coming along. Time to finally decide on gearing.

I'd like to know what engine speed I should target for mild sport type flying. I'm thinking around 12,500rpm?

My target headspeed would be around 1750rpm.

Good advice appreciated.

Thanks,

Ian Burns

I have run the stock Zenoah 20EI at 12,500-13,500 RPM. This seems to be the "power band" in my opinion. 12,800-13,000 is a good range to shoot for.*disclaimer: These are my opinions. Agree or disagree, Your Call :)

Thanks Sparx. Much appreciated.

I forgot to mention it will be a stock 20EI that I will be using.

I am saving my "allowance" for a dual jewel... I run mine at 12,500. It is too warm down here in FL to run any higher rpms right now. I'm at 240f on the nose at 12,500, with the 6.42 gear ratio, 600mm wide chords, and 2050 head speed.what does a dominatrix have in common with a heli? Both beat something into submission!
