A brand new Raptor 30 V2 with OS32 is only U$375. A Futaba 7C (lightyears better than the 662) with digital servos about U$275. Add a nice gyro for U$100. Total for a brand new state of the art setup = U$750


The used R30 is worth U$ 200. The radio and servos is worth may U$100. The gyro is worth nothing, maybe U$5.
Add it all up and you should offer no more than U$325.
