Hobbico Retracts
Controlmech, as weighed by my very accurate 4 pound digital scale. All three Hobbico Mechanical retracts weigh 7.0 ounces. But I did not have a retract servo on hand so you would need to take that into account. And I plan to operate my nosegear buy a Hitec HS 85 bb Metal gear servo that weighs less than an ounce. I hope that his helps. Now how about some ideas for which engine I should buy? I have a Macs header and pipe that will fit the OS 50 SX or I can buy a header for a YS 45 and use the same pipe on it?
