Guys,

I have a CHP E300, it is fitted with a DA100, CHP cannister pipes, fuel mixed at 40:1. Now that it has been run in on a 27x10 I have put it on a CHP 28x10 prop, due to the 27x10 'barking' too much.

I ran the set up yesterday and got 5400rpm on the ground with the CHP 28x10. This was after optimising the mixture with a tacho. This is too low, does anybody else have any similar experiences with a DA100 with the CHP cannister pipes?

Mine has had about 5 gallons of fuel through it and was run in well on a CHP 27x10.

Thanks in advance

Rob

A 28X10 I THINK IS USUALLY THOUGHT OF AS TOO BIG FOR A DA 100,MAYBE A 27X12 OR A VESS 27 WHAT EVER HIS PITCH THING IS WOULD BE BETTER.I KNOW I RUN A 28X10 ON MY 3W 106 AND IT IS A MONSTER

I ran a 28x8 Biela on my son's plane ;35%sd,DA 100, headers, and KS 86 pipes(rear exhaust),and it rips the heck out of the prop.

A mejzlik 28x10 is not too much load for the DA100. Most wooden props are way too much load though.....

To get best performance, let the engine rev and don't fly full throttle unless going vertical. This way you get MAX Hp out of the motor and quietness due to the prop not ripping.
