RE: Sam-Rai Build Thread
The clear coat was wet sanded first.
This was followed up with a polish and wax.
I'm planning to make some test flights this weekend.

The edges of the landing gear were rounded with a file.
Pizza cutter wheels were installed on the gear.
The gear was attached to the fuselage.

I temporarily installed the receiver, battery, and other equipment.
The wing was attached and the CG was checked.
The receiver Velcro was glued in place with Shoe Goo.

The engine kill, tank, and tubing were connected.
The Sullivan 3/32" ID (3/16" OD) diameter tubing is the perfect size for the engine kill.

The completed 426 model weighed a little light (59.65 ounces). Sixty ounces is the minimum weight for a Q500.
The wing was actually relatively heavy (21 ounces) due to a painted finish.
The fuselage and engine were light and resulted a lightweight model.

Very nice build Scott, lots of info and great pictures as always! 
I think it looks great and I hope it flys as good as it looks.
Good luck on the test flight.

RE: Sam-Rai Build Thread
Thanks,
There must be a few more models being built. Please share so that we can all learn and pass on the hobby to others.
FYI- I am using a Canon PowerShot A3000 IS camera. Set the picture size to small. I've found that it takes great pictures as well as movies. I bought it for around $120.
I'm planning to make it to the October 1st and 2nd KRC race.
See you there!

RE: Sam-Rai Build Thread
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.
