Gary,
I also would lean to the Viperjet if you want to go turbine. I also have a BVM .96 aermacchi which I flew before the Viperjet. I think the Viperjet is easier and more stable than the aermacchi. Landings are easier and smoother as well. Both jets fly really well slow and fast. The Viperjet is a big glider on landing it likes to keep going with that clean wing unlike the aermacchi which has to be slowed down a lot to keep from bouncing.
I built the nose gear door as well and have it on an air cylinder from Tam. Had 3 gear up landings from air leaking out of the BVM micro valve I had set up to retact the door after the gear. What a pain in the butt that has been> I have now purchased a Ultra Precision UP2 valve and it works flawlessly. I wish I would have known about that gadget from the beginning but it is a learning hobby. Get yourself one of the UP2 or 3 valves if you want to have the door sequence. It also runs the retracts all in one mechanical unit for $89.
It sounds like you are not in that much of a rush...if so wait and get one of the new ones from Tam.
Glad to answer any other questions you come up with.
If you want a Aermacchi with a brand new rebuilt BVM .96 and VioFan I will sell the one I have. I love my ViperJet now that I can use the brakes when the wheels come down
Also If you want smoke, Tam's smoke system is awesome two seconds of smoke on the ground will obscure a house!
Pretty simple to install and really makes the whole experience a blast flying.
All the best
