Or you could try to make a copy of one, mill it and cover it in Mylar film, tissue paper, of plastic bags.

They are fun to build, sometimes frustrating, but make GREAT projects.

P.S. If you make another one, put it on a table.

Haha I would make one but I am not going to have any time this week and I wanted it for this weekend. I found them for $80 new online but the website wont give me the shipping price until they ship it out, which I am not too fond of. Ah well maybe one will come along.

I posted to the classifieds before I posted this I just remembered seeing this thread and thought I would give it a shot

Thanks guys

Velie Monocoupe

Don't know if this qualifies as the radio and motor are from a Hobbyzone Champ...

Just finished my scratch up of a Flyline Velie Monocoupe. The build was fun, but the plane ended up needing an extra 8gms of lead (56gm RTF weight) in the nose. Hasn't flown yet; it's been dead calm around here all month until now!

Thinking about starting build #2 to incorporate the necessary changes to have the CG in the correct place without adding nose weight. I think it could be done and the benefit would be a lighter plane over all.

Stats: WS = 21 3/4", cord = 3 3/4", WA (usable) 70.31 sqin. RTF weight w160mah 1S = 56gms, WL = 115gms/sqft or just over 4oz/sqft.

Nice plane, round motor, tail wheel, how can you get any better? I wouldn't worry about the extra weight, you got a five cylinder radial!

I do hate to add weight though, could you "bump" the wing back a little? Or put the battery next to the firewall?

Beautiful plane, did you total your Champ?

P.S. It looks like a tail skid, not a tail wheel.

Disclaimer: No Champ was harmed in the making of this plane. On one of the RCG threads I found this link... http://www.wholesaletrains.com/Detai...p?ID=200841116 The Champ fuse comes with radio, motor, prop/spinner, pushrods and control horns (already mounted in the tail feathers) for $38US. The only drawback was the $15 handling/shipping fee. That's still only $53 delivered, which is cheaper than my LHS wanted for the radio alone.

dbacon The sad part is that the battery protrudes through the cowl to help balance the plane. I really don't want to build another, but there is so much that I could try to improve the plane that I almost have convinced myself to do it.

Test flights today. the Champ radio gave me some problems, but after switching batteries back and forth a few times it worked so I was able to run 4 batteries through the 'coupe.

First flight ended with a hard landing and a broken strut... I was sure I had checked the controls, but... After reversing the rudder servo I removed the non-structural struts and tried again. Ran the battery out and played with the controls trying to figure out the balance.

Second flight I decided to try to "shoot" a couple of pictures so with trans in my right hand and camera in my left, I got a couple of way-too-far-away pics. A bit of a rough landing, but the plane survived. I thought the plane had flown tail heavy so for the...

Third flight I pulled the battery about 1/4 inch forward... This is the flight when I shot the video. As you can tell from the video, the 'coupe was way nose heavy.

Before the forth flight I checked everything out and found that I had a bunch of up elevator cranked in so I reset the controls to neutral and set the battery back 3/8" from the last flight. This was what it needed! flew around on 3/4 throttle and turns were nice and flat with just a little control input. The flight ended with me clipping a weed and knocking the wing off on landing! Not a big deal as I had only tacked the wing on with 6 drops of tacky-glue so I could remove and change its location/angle of incidence if needed.

EDIT:  Took about 10 min. to glue the wing back on (no other damage...  Guess I'm lucky it didn't pop off mid air.  Fixed the broken wing strut, but don't think I will use them until I get everything worked out (or decide to jump straight into the next one).

Nice Video, I have to do a science fair project so I decided to build an ultra micro ugly stik with changeable wings. He has not flown yet but I will have a video posted shortly and tell you how the science fair went

UM Seawind

This is my little Seawind. It flies great, and very slow & easy. It is build with the original AR6400 from an SU-26, with a su26-xp gearbox and corsair prop.

Absolutely love the plane. Wingspan is about 16.5" & all up weight is 38 grams.











The UM Seawind with its bigger Electrifly brother(not mine)



And fully painted and cowled



For complete build photos, images of inside layout and the modified plans to make this plane please see my build log

Here is my Wing using the UM Stryker guts and a Multiplex Fox wing.
Maiden flight today went pretty well, but it needed some vertical stab area,
so I cut the tips off, beveled them and put them back on.
Try again tomorrow. 35 grams w/o battery, Flew mostly at 1/3 throttle.

Very nice, did you have any pitch problems?
