Legal for Profile ?

[Allan Perret]

OK, a profile twin scale design like Don Hutchinson's P-38, would it be legal for the Profile event if the main fuse was profile construction, but the two engine nacelles were built up with motors enclosed in cowls ?

Go read some of the rules in the different areas of this great land.  I would say no to the engines being enclosed.  I have an RC kit that has the P-38 engine booms in profile but the center pilot pod is built up to enclose the radio system that I was thinking of building for profile scale.  The rules I read said the center pod would not be legal.

 Not sure why you would want to build it that way but I would say no, not legal unless the nacelles remain as a profile.

    Probably not, but there are a bunch of different versions of the rules, so there's no general answer to the question.

Why not just change the nacelles to profile construction?

 Don's P-38 design is a profile, completely profile legal as drawn.

[Mike Keville]

No.

There's no unified national set of profile rules.  So what's going to be allowed in one spot may not be considered legit in another.

If you tried it in the Pacific Northwest you'd get ruled out on the cowls, but I suspect that the twin fuselages would stand, with much grumbling.

[Steve Helmick]

No, I don't think there would be any grumbling at all about the twin booms, as long as the engine exposure and fuselage/booms thickness rules are complied with. If there was a shear web or diagonal braces between the booms, there would be a problem.  Steve
