Will I got my extra in yesterday man was that fast shipping ordered on Saturday and got it Wednesday I still have not made up my mind on the engine yet so I would like to hear from some of you guys that have four strokes in them would like to see some pictures also if you got them. I was looking at the instructions and it said to put some pieces of balsa on the tail to reinforce the glue joint but did not see where vectorflight had supplied any for this so I guess I will have to use some that have laying around but I don't have any covering to cover up the balsa so what did you guys use.
