RE: How 2 use Profili?

BMatthews,

You may very well be right. I do have ACAD and can easily produce the wing with it. I think I will give your suggestion a try to see if I can use the ribs produced by Profili. After...

RE: How 2 use Profili?

BMatthews,

I thought about that but due to a design feature I have in mind, I don't know that I can get away with that.

I want to create a 1/5th scale drawing, using Profili for the ribs,...

How 2 use Profili?

Does anyone know if Profili 2.2 can be used to draw the wing and ribs for a P-51D? I see it can be used to draw ribs (with your choice of airfoil) that all the same chord but see no feature for...

RE: Price of Doss Steed's P51?

No, I didn't buy the parts from Doss. Doss passed away the next year in 2006, I believe.

I did however buy Doss' plans from Bob Holman for a good deal less than Doss was charging. After...

That makes 2 of us. I haven't heard anything about the model per se but know Don's plans require much patience and determination. I guess that's just Don.

I'd like to hear anything about this...

I know of a guy who is developing a 9 cylinder oil-cooled, gas engine that has radial gear reduction in order to turn a scale sized, multi-bladed propellor.

Price of Doss Steed's P51?

Short of calling Doss Steed himself, can anyone tell me how much the plans, canopy, fiberglass cowl and fiberglass intake scoop will cost me if I call him this week?

The reason I ask is that I...

RE: Doss Steed Mustang

Roger,

You don't seem to be getting any response from your post.

Why don't you drop by RCScaleBuilder.com and ask the guys there under the Other Designers forum.

Hey all,

I understand about about washout and such.

I also understood MinnFlyer's idea and probably wasn't clear in communicating my understanding of his concept.

I haven't covered the wings yet. The wings are from the Super Sportster 90/120 planset (71 inch WS) available from RCM that have been blown up 18% to an 84 inch span. I like MinnFlyer's idea about...

RE: bent wing - no not corsair

Just so you gentelmen know - and anyone else who might trip over this thread - I was able to fix that "bend" by adding the sheer webs.

I did do something a little differently though. I flipped...

RE: bent wing - no not corsair

I forgot about the sheer webbing and the plans do call for it. I'll give it a try and see what happens. I'll dampen the spars too.

Thanks, gents ...
