Tonight, we finished pinning the ailerons and elevators with 1/8" stock. Also sheeted the L.E. of the last wing. We then glued in both fiberglass tubes and the balsa stock that accepts the stab & elevator. We made the decision tonight, to mount the DLE-55 with the cylinder pointing straight down. We think it looks better that way. When I'm able to find some time over the next day or so, I'll make up the rudder..

FWIW the plane will fly fine after cutting off the lower chin. I, know that the original designer of this plane played with a balance of areas so the plane would fly the best in the knife edge position. For example, if you made the rear area of the fuse very narrow it would affect KE properties just as if you made the rudder really small... Missing area in the front may or may not detract in flight characteristics... Food for thought. BTW, I would imagine that if you cut off the top and bottom chin in the engine area that the difference would be noticeable for sure.

As mentioned before, it is a kit and the builder can do anything including making it a Guppy shape.... Part of the building process.

Thanks Richard.
We didn't really consider that part of the equation. Just the looks part of it. I do have to wonder though, just how much the loss of that small amount of front fuse would affect the KE characteristics. However, as you know, my experience with these planes is zero, so I suspect you profile guys would be in a position to know better than me about that. In any event, we'll still have the chin part, so if being without it negatively impacts flight we'll add it back on later.

Going by placement and some knife edge theory. By aiming the cylinder down and filling almost all the chin that your taking off your knife edge even by the best if pilots should not feel any different.

My engine points straight down and KE and KE loops are zero problem. Don't know why you'd want to put it sideways

50cc WrongWay next to a 100cc Carden Edge540


I was to cheap to buy a new muffler that's why I cut the chin off mine.

I like that idea. I also like the way James has the muffler sticking straight to the side on his 30cc.
