Default Motor mounting problem

I am putting together a World Models J-3 Cub 48. I purchased a Saito FA-56 for this plane and no matter what I do, I can't seem to get the motor to mount in the proper place. I have distroyed one nose cone trying to cut to fit. I can't seem to get the motor centered with the nose cone. I had to oblong the hole in the nose cone to center the cone to the motor. Nothing I do works. Any help would be great. [:@]
Thanks

Thanks, I am ok with that, but do you always have to cut the cowling up like that? I would think they would make it pretty universal so most motors would fit decent and the cowling would stay somewhat "stock" appearing.

yea, usually you have to do a fair amount of cutting, the muffler, needles, and fueling holes, but you shouldnt have to cut up the prop hole, maybe just a little but not much and you should always keep it in line with the spinner.

Gary's absolutely right. You have to put the engine where it's supposed to go and fit the cowl to that. I just finished up a Funtana with a Saito 91. The 91 is a little bigger than some of the engines that fit in there but still works just fine. What works for me is to use a piece of acetate (clear plastic) and tape it to the side of the fuse. I just use a single piece of tape and it acts like a hinge. I then transfer the different points to the acetate with a sharpie and also mark the edge of the fuse. Then take the acetate off and add it to the cowl and tranfer the cut out points. I like to drill into the cowl and then use a tappered reamer to size up the holes to the size I need or make them big enough to get the cone sander for my dremel into the holes. Here's a couple of pictures but it really does look better in person.

how ya like that funtana there Rob? that was one of the first planes i almost got before i decided on the 60 size ucd!! but i still may one day but i think it may be similar to my edge, but i thin my 66in edge may be a bit heavier at 8lbs[X(] but man is she fast and really surprised me with the flatspin she does, i bet the funtana will do a great flat too! looks great

MK7,

I had a WM Clipped Cub. It was a nice lil plane but I got rid of it last year. I had the same problem with the cowl lining up. I finally just took a Dremel and opened it to fit the shaft. Here are a couple of pics showing how it looked.

In the shot from the front you can see how the cowl was closer on the left then the right. This was before I used the Dremel to shave it down a tad.

I had a Magnum 52 FS mounted in the nose. I miss that lil Cub, but not enough to buy another one.
