3-D Flyer,
If the ARF is built the same as the kit, and the initial pics look that way, then the mod for the bigger engine is pretty simple. My kit was completely framed and ready to cover when I decided to go with the MVVS.
The engine rails are too thin to bolt through if you widen the cutout. The solution is to add an additional rail above and below the present rails. So, after some looking at the plans, I cut out the balsa cap strip above and below the present rails in the size of my rail to be installed. I then got a flat scrap of iron about 1/8" thick, long enough to extend as far as I wanted to insert the rail, and narrow enough to fit inside the fuse, heated it with my propane torch and simply melted out the foam to the desired dimension. Very easy, but be careful not to remove too much. Takes literally seconds. The existing rails act as a guide to slide against and once cleaned up give the glue something to bond the next rail to. Then, I simply got some oak hardwood from Lowe's, I think 1/2 x 1 1/2 x 12" or something like that for about $1.50, cut it to dimension, spread on some Elmers poly glue and clamped it. Once that was done, I used my band saw to cut out the spacing for the MVVS making sure to maintain centerline. The rear hardwood spacer between the two existing rails needs to be removed and pushed backwards if you don't want the engine too far forward. I simply cut it out at the glue joints, relieved the foam, applied glue, and reinserted it. Balsa and filler replaced as needed. I think I left the rails nearly flush to the nose. No pictures while doing this, unfortunately.
Total time, less clamping time, about two hours, and I'm slow.
Haven't yet flown it, but have complete confidence in it. Should fly by next week.
