I think front and rear halfs go for about 45.00 a piece. plus shipping. I may be wrong. Just shoot them a bell and get a firm quote. All of my screws were stripped and the front case was cracked. It cost me 109.00. That's the one thing I don't like about the Helios EX-10 is the plastics they use are very fragile. I guess they do this to keep the weight down.
When I ran the Hitec CRX. My son twisted the steering wheel off and Hitec replaced the entire transmitter for free including shipping. This happen twice. I love Hitec's customer service.
