Hi Guys,

Ok after my 500 crashed into a tree a few weeks back now. I destroyed all my servos and been looking to replace with z3650. However no body has these in stock been waiting a while.

However RC Hover got the new JR DS 3421 in stock. Great service and helpful guys over at RC, always been pleased with their service.

.15 seconds is very slow for a cyclic servo, wait for Z3650s, or if you see 3517mgs any where those are the new Z3650s.
