Status: offline 		My control throw meter measures in inches...I found this formula in another thread on how to convert degrees into inches:

quote:

ORIGINAL: scratchonly

Double the width of the control surface; eg 2" surface = 4"; multiply x 3.14 =12.56. Divide by 360 =.035. this is your inches per degree. 20 degree throw=..035x 20 = about .7 inch or between 5/8 and 3/4 inch. This will certainly be close enough.
This is all based on the circumferance of a circle which is 3.14xdiameter. Be sure to double the width of the surface.

So for me wanting 8 deg low rates and 12 deg high rates on the elevator I came up with:

Elevator Chord = 4" (I used the largest chord...Since it's tapered you want to be sure and use the same spot to set your gauge that you measured for the calculations... )

8 x 3.14 = 25.12 / 360 = 0.0697 (inches per degree which I rounded off to .070)

.070 x 8 = .56" for 8 degrees of throw

.070 x 12 = .84" for 12 degrees of throw


I know this is very basic Trig but I'm dumb and I couldn't remember way back to school so I had to go look it up...

Hope this helps...

Chuck

In post #1469 the last picture weigh the fuse by itself with no mount or any equipment inside, just the bare bones fuse ready for glass. I started around 27 ounces and by the time I'm finished and sanded ready to spray primer you should be about 30 to 31 ounces. That's using balsarite sealer, glass and micro balloons. If you have not, go to CAA's website http://www.customairframes.com/, to support and set up a user account. It's free and there is a world of info about this plane. He has a whole section on glassing and finishing that works great. I follow his methods and my last VF3 is below 10.5 with a DZ160. Just remember to think light keep track of you weights as you go. If you use single stage paint it's not necessary to clear coat your plane and it fuel proof. Also PPG Concept paint is what I use. It's more expensive but it has lots of pigment and it takes very little to get the cover you want. Less paint less weight. I'm just lightly touching the subject here and if you want send me a PM and I'll go in more detail with you.

I would like to post a small message just to congratulate the creator of the Black Magic and all the constructors. Because I think that nowadays, only few people have the courage to construct a pattern themselves.

I invite you to have a look on my constructions: the Graviton and the Anti-Graviton

Just a little update on the plane my dad is finishing up for me. As of right now the fuse is in Primer but the wings are covered. It was our goal to have this plane ready for Nationals this year but with my Dad's work load at his day job kicking up he hasnt had much time to finish the plane. But he was nice enough to let me fly his brand new VF3 that he finished this past spring as long as I dont mess it up.

This particular plane is stupid light!! the fuse was framed by the Man himself Mike Hester and he used the best and lightest possible wood in the shop to construct the whole plane.
The wings are really light weighing in at about 10.4 oz per wing panel after covering and thats with carbon Veil added under the wood for a little extra strength and stiffness. . so should be about 12 to 13 oz per panel after all the hardware and wiring.
The fuse itself weighs about 30 oz before paint and Im not too sure about the weight now after primer but it couldn't be much.

I would just like to thank Mike and Melissa for putting so much effort into this plane and you have done more than enough to help me out through the years and I couldn't ask for better friends.

as for the scheme on the wings, I would like to thank Jason Shulman for helping choose a good scheme that would show up well in the sky but also look great on the ground. Thanks Jas!!

here are the wings after covering.

Thanks everyone. More updates to come after Nats.

Now moving on to the fiberglassing the airframe.

Okay you have taken note on the weight of the plane before the balsarite. You might pick up an oz or less with the blasarite but it should be minimal.

the fiberglass is a 3 stage job. using west systems 105/205 mix up a small batch and reduce it 50% with acetone. The first stage consists of laying the .5 oz cloth on the fin post and 2 oz cloth on the belly area behind the firewall. Cut your cloth to fit, using a small brush apply your resin/acetone mix. then take a small handful of microballons and rub it into the cloth filling the weave. Your done for a soild 12 hours while it cures.

I'm of the understanding that when epoxy resin is thinned, it doesn't cure very hard/stays rubbery. Does this not happen with this particular epoxy or am I missing something here?

Note they are thinning with acetone , not alcohol. That is the difference.

Status: offline 		This is my new Black Magic VF3 for the 2011 season. There are a few small things to complete before the plane is finished. I have it setup with all airtronics servos and a YS 1.70 ( 1.75 by spring time ).

I'm sorry if the picture is bad quality it was taken with my cell phone.

Status: offline 		Mike was approached and he did pass the rights along to another party, no I am not at liberty to divulge, and that party is working on the logistics of getting the line of planes available again....BUT just as with most people....this person has a day job and a life outside of RC. Once the logistics have been worked out I am sure there will be an announcement but until then you have all the info available.

How much rudder deflection should be built into a VF3?

Thanks for the info.

I've put together 2 of these planes and they all had around 20 to 25 degrees of throw in the rubber. The last one I did for Chris I was able to get about 30 degrees for it. This plane does not require a lot of rudder for knife edge, stall turns or snaps and you will love the way they fly.

You'd better not fly it. Instead send it to me, I'll take one for the team on this. JK!


Looks AMAZING with that yellow/green scheme. Love the black pinstripe! Is that overlaid or put in between the trim colours (i.e. overlapped on one side)?
