RE: Nuance

Neko,

I wrote about this a long time ago and some use my technique with great success. Here's how I do it for medium sized gas engines, up to60cc (overkill for an electric motor BTW, but very...

RE: Nuance

I agree with Chris...no need for expensive epoxy. There are several good, inexpensive epoxies that are reasonably thin and are made thixotropic with fumed silica. PolyEpoxy from AS$S, CJ Composites...

RE: Nuance

Never did understand the need for rear rake of landing gear on Pattern models. I don't think I have ever seen it on full scale aerobats, with good reason...

RE: Nuance

The cradle looks good.

I make mine from PVC tubing from local home repair stores. The key for me, since I've used a minivan for transport since their inception in the early 80's, is to custom fit...

RE: Nuance

The new wing should be able to start and most importantly, stop snaps and spins more crisply. But I suspect that's about all the benefit to be had. The AC position of the panels isn't changed enough...

RE: Nuance

Of course you can. It's simple!There is one other element of course so please think about it and you will figure it out

I don't use prepreg; just too expensive for my tastes. And I don't have a...

RE: Nuance

Vacuum does several things.

Primarily, it exposes the joint toreasonably high clamping force. Typical vacuum in this app is around 22" Hg or around 10 pounds per square inch clamping force....

You're quite right! Any business operating at slim margin will not operate long. I love Pattern and myallegiance is set on the health of the sport. So any one that does what Chris Moon has done (and...

RE: Nuance

Fellas,
Sounds to me like it's a common fuse with different wings. Why buy 3 "different" planes? Why not just get the wings or (God forbid) build your own wings? Or even better, build wings to fit...

RE: Nuance

If the amount of vertical area is small, I tend to agree, it wouldn't matter much. But if it's rather large, say greater than 10 sq inches or so, angled surfaces induce dihedral/anhedral effect...

RE: Nuance

Lightness is in the foam used. Let me suggest that next time one has wheels with extremely lightweight foam tread, simply add a rubber ring to the foam. I cut mine from bicycle inner tube. Wash the...

RE: Nuance

Ha, ha.... Excellent Mike! Works for IC just the same.

The reasoning is simple: some of the most distrubed air happens right at the hub and does almost nothing to create thrust. Why not have...

RE: Nuance

Oh, aplogies; that sounds right. But I wouldn't call it "stolen" since I gave the idea freely to several guys back then. And of course, the several dozen gear sets I sold, all had it stock. I think I...

RE: Nuance

Wayne Galiger? It should be very similar. If I recall, he was one of the early ones asking what I did.

Eventually I used the technique in the custom gear sets I was building for people circa...

RE: Nuance

Moving a gear mounting block forward 2-3" is the key to the nose overs. OR, eliminating the rear rake of the legs. If these are wood planes, then the block move should be straight forward when...

RE: Nuance

Tony,

Suggestion....If you have a height gauge, establish zero of the stab. Then measuere the difference in heights of LE and TE on your wing and calculate the AOA. While you are at it, take a...
