Yep. He was my father. I learned everything about silkspan, dope, free flight, and so much more from him.

I love wood structures and yours definitely looks impressive. Great work!

hi,

what software are you using for the 3d design?

thanks
alex

any updates from the builder? we are eager to know the final results!<div>

Alex,
Software is Solid Edge.
Chuck is still covering. I am further behind on my proto kit.:'(

Any updates on progress?

I'm sorry guys, I'm just finishing my new home and working out of town.

Hope to maiden this weekend. Will update as soon as I can.

Chuck

Maiden Day!

OMG, best plane I have ever flown, no mixes, probably illegal and will be banned from competition.

Chuck

OK... for the real flight report.

Liftoff was totally uneventful, needed some up trim and a little aileron trim, touch of rudder trim.

Winds were about 10 mph and slightly crosswind.

I set the timer for 5 mins and being this is a prototype I am focused on getting the airplane to trim to the best possible and I dont want to test the struture of the plane till then.


So... couple of passes... time for KINFE EDGE flight.

There was no noticeable roll coupling but I did have a pull the canopy.

Stall turns.. fantastic, downlines are straight with a little roll but I think that may be due to some twist in a wing or stab, or y wings my be off a little since there are FOUR different wings with individual adjusters and adjusters on the stabs.

So, I am very very pleased with the initital results and its on to more trimming. I will keep you posted.

Thanks for all your positive comments and encouragement.

Chuck

Chuck, I see no wing struts, will the plane survive a snap without it? You may have already covered this in an earlier thread but not sure i read that part, hence the question

I hope, wing tubes in top and bottom wing.

Way to go Chuck! What a fantastic project. Keep us updated as you get it dialed in.

From concept to 3D modelling and building process, very original, fast and accurate work. Congratulations for the maiden flight!

Following the trim process and setup most carefully!
What are the initial incidences? All 0-0-0?

Well, intended to be 0 thrust, 1 deg right thrust .

Wings all set to .5

Stab 0


Ended up with wings at 1 before I figured out we have 1 up thrust.

I'm going to return wings to .5 and remove up thrust and this should remove most of the canopy pull.
