RE: Radios?
I just bought a Servo City Hitec Flash 5 radio with a glider flight package(3 hs81 metal gear servos, 555 rec) to use with the Unicorn wing I'm building. Buying a radio with a flight pack usually yeilds big discounts.
An expert flyer told me to get the top of the line Futaba, but he looked at the Flash 5 and felt it would be an acceptable alternative. The Flash 5 upgrade over the 3 ch focus radios seems to be a good enough jump for me now.
One big thing is the Flash 5 has dual rate switches and the Flash 4 does not. Dual rates are helpful in that you can instantly "tame" a highly acrobatic Wing/Terry Graupner for landing or switch to gentle controls for a new flyer.
I figured out how everything works on my Flash 5. It's well designed, easy to use, and real slick.
