RE: Electric Actuators vs Air?
I am just starting to build the TF P51 1/5 scale. I have the Lado electric conversions for the retracts and they truely are a "drop in" replacement for the air cylinders. I chose the DA-50 with the Keleo scale exhausts and I picked up a full fiberglass cowl and air scoop along the way. I am building mine as a "B" model using the Great Planes "B" conversion kit. I am not yet sure how much I will "tweak" the design as I have no intentions of attempting to build to anything except "stand off" scale at best.
