I made a couple more flights on the Sam-Rai today. I believe it will be a great 426 design.


Here are a couple things I found out:

1) When taking off mine does best with just a small amount of rudder and no elevator. If it doesn't take off straight then check the thrust line.

2) I moved the Center of Gravity forward a little more than the comparable 66012 winged model. Don't go back further than 2 7/8" on the initial flights.

3) For elevator throw use about 3/32" each way on low rate. On high rate mine is set with about 3/16" to 1/4" each way.

4) Low rate on ailerons is about 1/8" each way. High rate should be around 1/4" each way.

5) The gap on the ailerons must be covered on the bottom. I flew the model a couple times without the gap being covered. The model whistled as it flew by. This was corrected by applying a Gap Seal tape that is common for high performance gliders. The tape has adhesive on the front half. It is taped in front of the gap and the remaining half covers the gap.

Here is a link for the Gap Seal tape:
