RE: Question about Retracts (Corsair Gold Edition Kit)
The 615s get a lot of bad press, I've used them in a couple planes and they can be made to work just fine,,
I have not used the RS 333, but I do have their actuators in my p-47 and love the "no air" features,, I'd never go back to air unless that was the only option
By the time you buy a Servo, Air support kit valve lines etc., A pump??,, you spent close to the same as the E-retracts cost,, it's really a no-brainer IMO
