Propeller Test Citroën 2CV ultralight aircraft engine

[leneanderthalien]

35hp with the actual configuration? (the original car engine as 29hp DIN)

This engine is not interresting with direct drive: the power and torque are to low: much better with a reductor: this allow a big propeller= much better efficiency and more power

But the Visa 652cc engine is much better (alu-nikasil cylinder=better cooling and better efficiency) :is use on some ultralights like the german motor glider ULF2

Hi Renaat - just a guess, but try a little back pressure instead of those straight pipes to get that extra few hundred RPM. I am always surprised how a little back pressure makes an engine run a little better.

Buy two "supertrapp" clamp on motorcycle silencers, at least that's what I'm going to try here soon. You can really tune those types of silencers and I can send a link if you want.

Half a world away we were doing pretty much the same thing this weekend!

@FPVandotherprojects Those pipes are actually VW Kever silencer pipes, not straight pipes. Is this good the way it is?

@iRenaatsouvagie Oh, that should work well for a little back pressure. Sounds like it is running real well as it is, good job!
