Well, UM...'prop savers' are nothing more than a collar with 2 screws to hold it to the drive shaft and an o-ring holding the prop to the screws. You can make your own, and they do work very well.....unless you hit the wrong rudder while attempting a KE at 15 ft. Then you need a 'plane-saver'.

UM...so I've heard.

OH....and get some Lipos. Yes you need a different charger and Yes you may need a new ESC, but as you advance in electrics you will need them anyway. You can get a brushless motor for $20 and an ESC for like $35.

You can get an entire plane combo with everything but a transmitter for under $200...and they fly great!!
