Hi, On mine I used Volts Wing Max HP on the ailerons and the 2721 metal gears on the elevator and rudder in the trays provided,Any thing more is over kill the plane will weigh in less than the ducted fan version due to the light weight of the Bee, I upgraded to 4-40 pushrods for the rudder and elevator!!! dont forget to glue and glass the rod sleeves in several places so the dont move,I would use the Thrust augmenter pipe!! you will pick up another 1 lb with the JF 50 Bee Only! We have over 50 flights with no problems with this radio set up, for fuel I used 2 round cylinder tanks of 8 0z each under turbine to each side and a 32 oz in-between the intakes If you can get a 40 it will exstend your flight time but not really needed (you will need to cut out some of the intakes) with the uat on top, don't forget to also bolt the main hatch also it could blow off with the ram air pressure, And you must use 6 volt receiver pack with the Bee! Also Good luck, and use spring air retracts milled for the 3/8 robo struts, bvm 2 1/4 wheels and brakes smaller nose and use the scale yellow nose strut you will have allot of fun with that scooter!!!

you can see video type in Yellow A-4 in the Rcu search to find the link!
