I assume you meant the 4*60? I have several engines on the shelf I could use, but I have settled on my just broken-in Magnum 1.08. So far, I have it mounted on the firewall with a Hayes motor mount - inverted, at about 1/4" higher than the thrust line drawn on the plans. This way, I can use a fully enclosed cowl if I choose, and the carb would be high enough to mount a 16Oz. tank centered to it.

The 1.08 is a little heavy for this plane, and even with it almost butt up against the firewall, I expect the plane to come out quite tail heavy. I'll be sheeting the turtle deck and mounting the rudder servo (and elevator servo, if necessary) in the back to compensate. I don't want to add lead.

I have replaced the stock landing gear with a larger heavy duty aluminum one I bought at a swap meet, so prop clearance shouldn't be a problem. I didn't know it at the time, but two of the three holes on the gear actually matched the 4*60 LGM perfectly.
