Thought I could build two as easy as one, well..........almost. I started on them Oct. 28th.
They will be powered by PA.75's, one with pipe and the other with header muffler. The batch of Sig contest balsa I ordered was prompt, and great light wood. Most everything is in .002 carbon with 6 coats of clear, the open bays are covered with polyspan. The noses are covered with fiberglass cloth and z-poxy. Both wings are constructed from a Bob Hunt SV 23 "lost foam" cradle. (Bob, this is #12 & 13 wing I've pulled from the cradle you sent me in 2002). Controls are, 4" bellcrank 7/8 to 1 1/4 front horn and 3/4 to 3/4 horn to horn. Tip box, motor mounts and sliding leadouts are all from Tom Morris. Final sanding in progress and I hope to lay some automotive gray primer (lacquer) the first of January. Completion date.......Feb.? Going to Indy to see Roger Wildman and put them on his "official scales". More later.

Blessings
Allen

Just out of curiosity....is the fibre glass stronger than carbon matt and is that why you used it on the nose?

Very purposeful looking Allen and they both look like they deserve a speeding ticket for just standing there!

Glenn, I've always used Z-poxy and fiberglass for two reasons, for straight and durability. It seams like the nose takes more punishment than other parts of the airplane, at least mine do. I started glassing the nose and the cow ever since I built my first Randy Smith SV-11, (1990?) because he included the glass cloth with the kit. I just copy all the good things the "in the know" stunt guys do.

Blessings
Allen

oh ok. Now another question....why Z-Poxy and not regular epoxy?

Sands MUCH easier.

Outstanding beginning, I know these two will end up great models.

Another edit.

Tell us more about your fiberglass cloth system. What weight fiberglass cloth are you using? What time Z-Poxy are you using? It is epoxy and not finishing resin?

I have a Nobler on the board and would very much try your idea on it.

Thanks

Very nice work.

I thought that once. All I found out was that it was twice as much work.

Looks GREAT Allen, both of 'em!

Jay, I'm sorry I cant give you the weight, I just used what was left over from some Randy Smith kits I built long ago. Ask Randy.
It is finishing resin. I put on one light coat then lay the cloth on and brush on one more coat. Then heat it with a heat gun and take a rubber squeegee and squeegee the excess of. You will find a lot will come off. Don't worry about the cloth hanging off the edges, it will sand off. Then lightly sand then apply a filler coat of dope/filler, lightly sand then several coats of clear, lightly sand. Your ready for primer. My airplanes have always scored 15 or 16 at the Nats, so you might want to quiz a front row guy like Howard Rush, Bob Hunt, Kenny Stevens, etc. They are the people who know how to finish. Hope this helps.

You are right Mike, it sands easier.

Blessings
Allen

They look like winners to me.

Do these things have a name?

Allen Brickhaus · « **Reply #16 on:** December 20, 2012, 09:24:37 AM »

Petra ? and Petra ??

Another alternative to the Z-Poxy for fibreglass is the 20 minute "finish cure" epoxy from Smith Products. It's the glue line that most hobby shops sell with their shop name on it. I've used it on glass and as a fillet material when mixed with micro balloons. Sands nicely when you need to.
Type at you later,

Does anyone know what fiberglass clothes Randy uses?
Thanks

Z-poxy is a Finishing resin that hardens to a solid state.
Reg. epoxy just never gets there. It usually will gum up your sandpaper unless your willing to wait months.
