Status: offline 		Finished the fuse for the wing tonight. Its a partial payment for the benefactor of the molds. I think it will fly good, can't wait till the test flight.

The fuze is glassed and painted. It contains 3 servos and a Heavy Duty JR switch. No fuel tank, battery, or receiver.

The weight is a RCH under 1 lb.

With the wing at just over 17 oz, and the addition of the engine and radio, I think this will be very close to weight.

The weave is not perfectly filled in the glass, but it is VERY smooth. Other than cosmetic, I think this will be a very fast plane.

Wet Sanded with 1500 grit, then 2000 grit.

After that, rubbed down with rubbing compound, then polishing compound, and finally a couple of coats of good Carnuba wax.

This slightly takes away the glossy finish, but gives an extremely smooth surface, which I feel is more important to speed that gloss and glitter.

Status: offline 		We had a great day of flying today, strong wind, but right down the runway. Got some Q40 flights in anticipation of the Champ race at the end of the month.

The seeker above made its first two flights and it wasn't pretty. I spent a good hour plus setting the tail, and bypassed the coldies, but I definately have the LE of the tail too low. It climbed very bad, but Jerry E made a great landing after shutting it down. We moved the CG forward, and shimmed the TE of the wing, but it still climbed liked crazy.

I am going to crack the tail loose and fix the incidence problem this week, and hopefully get a couple flights on it next week.

Very frustrating, after spending so much time on this plane.

BTW, final weight was 3 lbs 9.5 oz. Not bad for a fully fiberglassed and painted plane.

Status: offline 		I took a good look at the tail this morning, and think I have identified the problem.

Yesterday, Lee noticed the tail was warped, and sure enough it is. One side is a little worse than the other, but it has a nice warp on both sides where the tips at the TE are twisted upwards, giving the tail a bit of washout.

This explanes why the bubble level was perfect at the center of the V, but still climbs.

I cut out a wedge shaped notch just under the V-Tail on each side and lowered the TE of the tail by an 1/8". Just about CA'd the linkage, but its moving smooth now

I cut off the top sheeting behind the tail and smoothed out the transition. Just gotta clean off the wax and airbrush, and hopefully it will be as good as new. Will add a couple rudder clicks to even out the extra twist on the one tail half.

Not optimal, but should still be flyable. We will see next week.

Status: offline 		I have read this thread and am curious how things worked out in the end, perhaps there is a supplemental thread elsewhere?. In particular I am trying to decide if I should make a mold or continue to vacuum bag my wings. I have done 5 vacuum bagged, paint on mylar, skinned hinge wings and am getting comfortable with the methods, and am just starting to get a wing into the right weight range (16 oz ). This year I am making a mold for my fuse and tails and am undecided on the wing. I do not intend on selling, just want a good product for the least amount of effort.

I am interested in knowing the effort required to do bagged wing vs. molded wing, I will cast my own mold from a new wing if I decide to go this way.

Thanks in advance for opinions

Kevin M

Status: offline 		Kevin,

I am happy with the molds, as long as I stick with PVA. Molding wings has a large learning curve, but there are many people out there that are willing to help. I would suggest to anyone getting into this to start with a tail before doing a wing. It is much easier to learn on a small scale as opposed to a wing.

I pulled a wing out of the molds the other day, and just put a mist coat of PVA on them this afternoon and will be painting shortly. Pulling wings out of molds is easier, once you know what you are doing.
