Hi Ron,

Thanks for the kind words. Since the last posting, I have built the horizontal stabiliser and elevators and will try to post some photos in a couple of days.

I agree that maybe I should have glued the wing tips on before separating the aileron / flaps from the wing but since I had some problems with my last build (read careless with glue), I decided to leave the tips off till last. This way, I have to do a bit more careful sanding but the upside is that now I can accurately match the countour of the tips with the ailerons once the Robart hinge points are in.

On my last build, the wing tips came out slightly shorter than the combined wing / aileron width due to the hinges and a slight hinge gap, so I had to shape the aileron tips a bit to compensate for it.

The Pennzoil has the Moki 1.8 on a Moki radial mount with the vibration isolators from Apache. Frankly, I don't see much benefits in the isolators, even though they are good quality because the Moki runs quite smooth and has very little vibration.

I did use a single servo for both elevators on the Pennzoil but didn't quite like the joiner and made one slightly thicker and longer. I will probably use a separate servo for each half on the Pepsi and then some pull-pull for the rudder.

I know the rear mounted servos offset the heavy nose, especially because I will be using a G38 in the Pepsi (the Pennzoil balanced exactly with everything in stock position) but I am willing to put a bit of lead in the tail to compensate for the servos being inside the fuse. I don't like the look of the rudder and elevator servos exposed, so I will most likely take this approach.

Good luck with the RCAF - maybe it will be my next Chipmunk.

Best regards

Ari
