Help! Fastest Airframe for 6 inch prop?!

[Houndpup Rc]

Do you just guess the speed or do you have a speed meter? (or what ever its called)

Educated guess.

 

[Mr Man]

I got a feel for it when he let me fly it.

I'm considering buying a digital gps speedomer though.

Oh okay. I was just wondering if there was one you recommended.

I wonder if making a thinner airfoil on a FT Arrow would add speed.

Less drag, so yeah.

I wonder though if it would make that much harder to fly and how much of a difference in speed it would actually make to change the airfoil. Might try it.
