RE: Gohbee stinger 50
Yes,
many parts works on Rappy under the head assembly, just verify the web site Gohbee.com. Also you can improve your Rappy wth Gohbee underslug "flybar" head -"more responsive". The advantage its the price and good customer service from David.
for example - you can replace your Titan boom by Stinger 50 boom+belt for le$$
best regards
