Default RE: DL-50 engine
I took my Ultra RC Yak 54 out to the field for some tests, Ves 23a, vess 22b stock exhaust and KS canister. DL 50 ks canister Vess 22b = 6700 rpm 22 lbs thrust
ks canister vess 23a =6990 25lbs thrust. I then switched to the stock muffler (very loud) and what a difference. Vess 22b 7200 28lbs Vess 23a 7590 35lbs thrust.
Wow, I never thought it would be that much difference. I didn't fly due to the bad weather. It is now a must to fly this plane with the stock muffler, that gives me 2:1
power to weight ratio. It ought to be quite lively.


Has anyone tried the mt can and header on this motor?
