RE: 4*60 build question
Iwould offer this advise. Side mount the engine. Fiberglass Specialities makes a cowl that should accomidate the engine on it's side. You can the rotate the carb 180 to change the spray bar height. That is my plans for my third 4*60, the kits on the shelf, but has slipped back on my list for now.
Other bashes for it would include a built up aileron on a clipped wing. Round the belly a bit. Really bash the canopy. Iwould also add a half inch to both the rudder and elevator. I've seen them with a curved outline and they look great. You could carry that to the wing tips also. The list goes on and on.
Don't forget though that you need to re-enforce the landing gear mount as well as the fuselage sides at the former at the TE of the wing. Those are two weak areas of the design. Ialso snapped the tail off on a bad landing. I dipped a wing and when it clipped the runway, the plane started a cartwheel. The tail snapped off right at the LEof the horzontal Stap from the snapping action of the cartwheel.
The engine is a good choice for that plane also. Prop it with an APC14x4W prop and you will have all the vertical you want.
The kit builds tail heavy, so you could space the engine forward about 3/4" to 1" to eliminate needing the 8 or 9 oz of weight for balance. with the cowl, it would clean things up nicely.
Photos when you get started please.
