Dox,

I fear Jim may be right but I'll check with Don anyways to see it there's interest. If there's no interest then maybe I will build it and submit it to the classic pattern image base.
I agree, it's possible that Don might not go for a 32 size model what with all the 60 size designs he has now made molds of. However, if you find interest in folks here who might want one, then it might be doable. You could drum up the buyers and then see if Don would take it on for a given number of sales up front.

It looks like a simple fuse to copy w/o the vertical tail.
The complexity is not so much an issue for Don, it's the cost of materials and time to make the mold. The nice thing about this fuse is that it is finless so that makes it more compact and easier (lower cost) to ship. Alternatively, the fin could be built, installed with an eagle eye and then the mold could be made of the fuse and fin. But maybe this is not possible due to the location of the stab.

It weighs in at 8.7oz or 248g but it has been cut for a side mount engine. Uncut would be 9-10 oz I think.
That's pretty good. I guess it is a 42" fuse without a fin. 55" fuses with fins weigh 16-20 oz. An 8 oz fuse would be ideal for a sub 4 lb model.

I agree it should be as light as possible but don't you think this was meant to be a missile?
Sure, it's meant to be fast but also smooth and graceful. 45's and 50's carry 5-7 lb models so I can't really see a sub 4 lb model with a 42" fuse and 49" wing having a 45 shoehorned in there. IMO, the wing just doesn't have the squares to carry 5 lbs or more in a classic pattern style. What are the root and tip chords of the wing? I have a glass/foam Blue Angel kit with practically identical specs. The model is designed to fly with a 25. I plan to put a piped 25-32 in it with retracts.

Note that if the model is built to sub 4 lbs, you can use light 5 oz trike etracts on it. Either way, I'd build a very light core wing, stab and fin and see how she turns out weight wise. You can always build a wood fuse if you want to preserve this one. I'm fairly confident that you could wind up with a finished 2 lb airframe - painted fuse/fin and covered flying surfaces.

I have a Magnum Pro 45 which is 2.5oz lighter than the YS45FR. Maybe this would be the way to go.
How much do they weigh?
