AX-O's Fastback RV-4

I now understand your painting strategy.

It's going to take a long time to finish at this rate.

(Sorry for the thread drift Axel...back to you now...)

Axel,
Thanks for posting all the updates to your RV4. I think you have the perfect setup now for an RV4. I had an RV4 with a carbureted O-320 and a Catto prop that was the nicest flying RV I’ve had (I’ve had four) - and the most affordable. The best improvement would have been a constant speed prop, but that would have involved making those blood thirsty cuts in the firewall step. I built another RV8 instead. I just installed a Whirlwind 200RV on our new RV8 (my third on an RV), and I also recently installed dual E-Mags.
My question for you is, what benefit have you realized by having the EI Comander? I’m not racing my plane, and don’t plan on any competition aerobatics. Is the standard B curve sufficient? I have an IO-360 with 9:1 pistons and an Av star FI system. Event though I can’t adjust my timing in flight, I don’t know if I need to. Maybe you haven’t flown yours yet, but if you have, please let me know the advantages of the EI Comander.
Thanks

Thank you, I hope all this work is worth it.

I have not flown yet. will let you know how it goes. I can tell you that it was very easy to send a curve compared to the previous way of doing it.

Hopefully this wont start a thread drift. These types of questions are like asking what kind of primer to use

Not to drift this cool thread, check your PM's.

What is the advantage of a CS prop for racing? Or did you add it for a different reason? I would have thought that for a race there is only one speed range...balls out!

(Ps...balls out is a reference to the brass balls on a steam engine governor. Nothing to do with anatomy, just in case anyone might be offended ��)

I did not do it for racing. I expect to loose 2-3 knots top speed. That been said, One of the things that killed my speed around the track was exiting the pylons with low RPMs. The RPM would drop and i would loose a lot of speed. It would take some time to build the RPMs back up. and by then I was in another turn. So my time around the track may be slightly afected now that the RPM would remain constant.

Not sure I will be racing at Reno with this plane any more. The plane just gets beat up and a non-boosted or non-nitrous RV in the sport class is not guaranteed a spot in the field of 36 now.

I have mixed feelings about this convertion. However, All this may go away once I satrt flying. TBD at this moment.

I think you will love the constant speed prop!

Having gone from planes with, to planes without, I agree. What keeps me away these days is simple: Money. Just can't justify the expense the complexity brings with it, for the amount of flying I do.
