Thank you for your appreciation. It is pilots like you that make the extra time to do this thread worthwhile. You have made a good decision, leaving out the retracts. Not only does it simplify the build it reduces the wing loading, important for new pilots. I add for others to check the vertical location of the nose wheel retract. I am not sure it is correctly located.

Be sure and read the Twins section of the forum, there is a lot of good information re: Twins. Check threads by "Twinman"
