I suppose it's all a matter of weight, expense and complexity which mitigates against a constant speed prop. I guess it is like the glass/steam cockpit argument but I wouldn't pass by the extra efficiencies and benefits of a CS prop. It certainly would have negated some of the issues you have seen. Of course, it may have thrown up other problems........

I'm building a -10 so won't be doing aeros but that would seem to me to be an extra good reason for a CS prop. In the meantime, I am flying Warriors and Arrows with a club. I find the CS prop in the Arrow makes the aircraft much more stable in speed in cruise apart from any other benefits.

It sure did, I took it out again yesterday and flew another hour over the airport, the temps are reading much better already. At full throttle and mixture at 3200 ft, cylinders 3 and 4 are both reading 365 and 1 and 2 are reading 380. I think with some modification to the air Dams on 1 and 2 I can bring them all down within a few degrees of each other.

I'm not to happy with the Propeller however, It is a fantastic Cruise prop, once you hit 125kts it will accellerate like you wouldent believe however getting to 125kts takes to long in my eyes. I am going to talk with Craig today and see what we can do to maybe loose a few MPH on the top end but gain it in acceleration and climb.

Overall however, it is a fantastic airplane, simply amazing with what you can do with it.

I see in one pic, it appears your gearleg is exposed....do you have all your fairings in place?

As long as you aren't overheating your engine, I wouldnt fuss with prop pitch. Get a little time on the motor then get all the legs and wheels covered up...including upper and lowers. She'll fly different

Default Final conclusion

David, thanks for sharing your experience.

I'm interested to know if while troubleshooting the lack of fuel in cylinder #1, did you guys come across some FOD in that injector or do you think the obstruction just cleared itself.

Thanks.

We were unsuccessful in finding any FOD in the line or injector, however the injector is so small that i doubt you would be able to see it. Also the data shows that it cleared itself and the power came back, it fluctuated a bit when it did come back on line but there was power there.

I put another 2 hours on it tonight without a hitch, the machine is amazing.
