Hey Gee, thanks for the reply. I am using the nitro version with the stock servo. I think its weird that they use a piece of tubing to keep the dogbone in place. They could have used a longer dogbone. But it does explain why i lost the second dogbone soon after the first one.

I am using 4 Sanyo 1600mAh NiMH rechargeable AA batteries for the receiver and servos. What servo can you advise me as a replacement? Is it better to use a humppack instead of AA's?
