Done a little more work on it this evening.. Sanded out the stuffing tube hole in the radio box, sanded out the exhaust pipe opening in the rear of the hatch, and made a hole for the plug cap to sit in.
Space is very limited in this boat, hence the need for the plug cap hole (engine sits too high), the slot in the rear deck for the pipe (manifold doesn't go high enough), and the radio box slot, which will be reshaped when the stuffing tube is in the boat. There was only about 1/4" clearance between the bottom of the box and the hull, to be able to get a quarter scale servo in I'm having to use a deep V box.
There's going to be two problems with this boat, which I can do nothing at all about. Firstly, it's going to have quite a high center of gravity, owing to the fact the engine has the magneto pickup on the side of the engine. This is as low as it can go while the engine is still able to rock, but the engine is still quite far up. Second problem is quite obvious, it may have the center of gravity a bit too far forward. Nothing that can't be solved with a bit of lead as it's not out by far, but I'd rather not have to.
Other small issue is that I may have to have the radio box lid made out of aluminium, to stop it melting. There's a good half inch of clearance though, any thoughts? The pipe physically cannot go any higher...
I'm currently waiting on postie to bring me the throttle servo mount, throttle servo (Savox SC0252MG), twin 500ml fuel bags and the stuffing tube.
Shaft support will be moved a bit next, then I'll get the stinger on then it'll be time to paint
