General Western Meteor Monoplane


Just had the maiden flight of my new Meteor monoplane. Geared (2.3:1) 6V Speed 400 on 8 old 500AR cells. Weight is 26 oz, wing area is 300 sq. inches. Covering is aluminum Litespan (BOO!) with black craft tissue and Sharpie pen trim.

Was a bit slower with an APC 8X6E than I expected, but showed no bad habits. I only flew it for about 3 minutes, then landed as the Sun was right off of the approach end and made visibility miserable. I'm thinking of putting in a geared brushless, but it has to be able to fit where a Graupner gearbox does -- any suggestions?

I've been shooting photos during the build and have drafted an article on it for submission to Jim.

Another shot, catching Micki, my wife as she takes photos of the plane for our scrapbook (I'm not allowed to fly anything until she has a picture of it).

Any ideas on a brushless?

Very nice model. If you want some more speed, do as I have done and install a SAITO 53 cc 5-cylinder radial engine.

(Just kidding, my model is quarter scale)

If I bought a glow engine, I'd better have a fast car, too, so I could get away from my wife, because she hates glow engines

Very pretty plane.

I'm guessing here but a Mega 16/15/7 or /8 would probably be about right as they can swing a pretty big prop and use your batteries. You might want to ask in Power Systems.

Will a Mega motor fit in a Graupner gearbox?

Hi Bill
Cute little model - hope the plan escapes into the Great Wide World. Parasols just have a certain 'something'

But if Sue found me publishing shots of her from that angle - I'd be out of hospital around Christmas

Ah. I THINK that you can use an MPjet25/35 with teh adapter kit that clamps on teh motor to get a beam mount.

Actually, a better upgrade would be a long can 480, and a 9x6 or 10x7, in fact you would probably find a 9x6 on it as it stands would improve matters a lot.

Your original combo is more right for a 22oz plane ...

Shaft is wrong at least - 3.2mm v 2.3mm

I think the Mini AC range has the right mounting holes and shaft diameter.

But the FG series box is pretty poor frankly. I'd change the box and make up a new mount.

With the Mega you wouldn't need a geabox if you went for a high wind (7+). This would also make the plane quieter.

you could also go for one of the outrunners, I here they swing a pretty big pop with authority.

Just a quick update. I decided to go the easy way and replaced the 6V S400/Graupner 2.33:1 gearbox with the 7.2V equivalent. Since I just happened to have on hand two 10-cell packs from my wife's Miss 2 that fit fine AND keep the CG good, I thought I'd try it.

Result: I gained almost 10 watts/lb, with only a 2 oz. overall weight increase. The Meteor flies much better now, and doesn't show any sign of the increased weight.

p.s. Yes, Dereck, I know this is what you've been preaching for some time!

he other option would have been to put a long can 480 in the same box. More power, better efficeincy, and not so much extra weight.

In fact you could drop to 7 cells on that setup...

Good thought. I went with the 7.2V as I know it works -- it's what's in my wife's Miss 2 as the stock 6V is neither powerful enough nor heavy enough.
