Bob Martin already did. It's called the Mystery Ship. Well not really. Bob didn't have the hi tec materials and the better understanding of structures to design from.

About lift: You will always find lift in two places; behind the sun and over the tow lines.

Where's the lift?

I agree. It seems to like those two spots best.

I agree. I would reduce the dihedral a bit.

How about a brushless motor setup?

I would not reduce tip dihedral in this model. In fact, I have found that increasing dihedral or adding tip dihedral makes most sailplanes much eassire to fly. I recently increased the dihedral from the stock 2.5 degrees to 5 degrees (changed to a 10 degree wing rond) and found roll stability to be much better without affecting controllability. I also added tip dihedral to a Grand Esteem to improve it's lateral stability because it used a carbon fibere wing rod.

ChuckA,

Well, I also agree with you when talking about a RES ship. I was responding to a question of fitting the Hawk with ailerons. In that case, I would prefer less dihedral. Pilot workload would increase, tho, as would the weight.

My Hawk outperformed my BoT yesterday in light lift.

And you'd REALLY think of making an ELECTRIC out of it????

My challenge was to make a full house Houston Hawk, not a wood fuse for the Legend. And, no one has taken me up on it AFAIK. AJ did seem to be somewhat interested in the concept.

My reference to the Legend was to my earlier musings of building an RES wing for it. It seemed to provide some chuckles to a few of the forum members.

I'm just about finished with the guitar project. I have plans of building another but it will be after a few models. The finish on this thing has to be seen to be believed. I put on 2 coats of sealer, sanded between and after. Next (last night) was 5 coats of finish. Today, said hello to George Bush at Texas A&M (son-in-law graduation) and back to level sand everything with 600 and add 5 coats tonight...1 hour apart. I'd be a decent luthier... This is coming out nice... BUT WHAT A PAIN IN THE @$$!!! I stopped in the middle of the Houston Hawk and the WileyHawk to get this done before Christmas. I hope my youngest son appreciates it for that fact, alone... and I think he will.

Speaking of which..... Merry Christmas everyone!!!

Would that waterbased lacquer be any good on obechi? You going to be at the field tomorrow?

Happy Holidays to you, my friend!

Spruce


To keep it on topic, I have to say something about the spruce. Airplane mongers have nothing on luthiers when it comes to spruce quality. I think I was just lucky with this guitar kit, but the spruce is fabulous. It's close grained, anout 20/inch at the widest I can find. The grain is just about perfectly straight. The cross-grain silking is there but not enough to be a problem. Anyhow, the white plastic binding got thrown out for some alternating rosewood/maple bindings... much prettier, and more indicative of a handmade guitar.

Enough ramblings...

Coupla pics......

confuselage say...
I'm going to keep us solidly off topic because my interest is piqued. How much is a guitar kit like that? How long does it take? When you finish it, tickle the strings a little and let me know how the sound is. If it's anything like my Seagull in sound quality and looks, I'll have to give it a go.
