I/VE HAD TWO UPROARS AND LOST FIRST ON DUE TO A FLAME OUT LOW TO GROUND ON WRONG END OF RUNWAY. DIDNT MAKE IT BACK AND CARTWHEELED IT IN THE DIRT. IT IS REPAIRABLE BUT FOR 40 BUCKS AND BOUT ANOTHER. THE/RE LIGHT BUT NOT REAL STURDY. I ADDED AN INCH TO RUDDER ON SECOND ONE AND IT DIDNT SEEM TO CHANGE IT MUCH. HAD A ST 51 ENGINE ON IT AND ITS A ROCKET WITH THAT, SO A 46 WOULD BE PLENTY OF JUICE. CAN/T BEAT IT FOR THE PRICE.
