Hey Joe,
Funny with the receipts...I'm in the same boat, hehe.
I just picked up the Kontronic setup that Greg used too. I am balancing the plane right now.
It is a 3.2 mm dia. shaft on the motor, I picked up one of these...
MJ4702 COLLET PROP ADAPTER 3.2MM from
www.hobby-lobby.com
If you cut the stock number and paste in the search box on the site...it should come up; otherwise look under prop adapters.
I am still a newbie but I recommend picking up a few wing tips too, I already broke 2 they're kind of brittle.
I think the prop is a 5"X 4.3 but check the writing on the stock prop to be sure. Any prop that size should work.
Also had problems with servos getting loose. And I seem to need alot of weight in the nose to balance wing.
I think that it is due to the lack of weight of the Kokam 11.1/1500mah batteries.
I had a Himax 2025 in the wing and it was insane, 70-80mph. I can't wait to see it now.
Good luck,
Joe
