Rev, go ahead and do it, you will have lots of fun building

Nice going with the building cession, looks like you are well on the way with the chippy reconstruction, I wish I could get a bigger Chippy in the near future, how about some pictures when you get a chance.

I have been under the weather for the past three days ( no work for me ) but feeling much better today, I had a chance to keep working on my Chipmunk, had to move the battery about 10" forward to get her to balance at the recommended CG, the CG was about 3/8 behind the recommended point ( no wander she flew tail heavy the first flight [] ) the battery ended up under the fuel tank and against the fire wall, also I clear some of the screws wing mount as the flaps torque roads were pushing it at full travel.

I did a quick check on the wing/stab incident and it looks like when the horizontal stab is at 0 degrees the wing has +1/2 degree of incident, now that I change the CG by moving the battery forward I like to see if the downward elevator goes away if it doesn't then I will have to take a closer look at the wing incident ( tomorrow Thursday test fly with new CG )
