$124 for the kit, and all you need is covering, radio and motor, along with some glue and building essentials, I think its a fair price.  All hardware is included, wheels, tanks, fuel line, motor mount, etc. 

There are more expensive kits out there that you still need to buy all the extra parts for, there are less expensive kits out that you need to buy all the parts for.

Find an ARF in this size for $124 that all you need is a radio and engine for. There aren't many choices unless you get the chinese ones that have no spare parts for. And those aren't very good quality.

Mine is almost done, just finishing up the radio install, need to hook up the rudder and elevator, and install the switch and RX once I decide on which one to use. I will be firing up the motor today.

Since I installed a 4 stroke OS 52 on it I did need to get a throttle cable instead of the one that came with it, and that was my only additional hardware I had to buy. The tail wheel mod was spare parts from my P-51.  If I went with the tri gear, then the cable would have been the only non kit part.
