Hi again Bob,

First of all the tests are done on the test stand. I got my extensions yesterday and I have gone with 1/2 inch rather than 3/4 inch.

I will work on the engine tomorrow as I have it mounted and ready to go. If I have any problem I will take it back to the test stand and work with you on it!
The plane that I really like is the basic Morris SU DO KOI. Although not stock anymore it basically looks the same as the orgional. This is #9 build out of the 12 that I have scratched built. Each one is better than the last. I usually get between 200 and 250 flights before they show the stress of what I put them through,so I retire them and "fire up" a new one. (It takes about 4 days from stick to ready to fly)
The tank is in the wing and covered with foam. Do you think that perhaps I should mount it on the Fire Wall?
I'll get back to you tomorrow!
