Just a couple of shots of my third in a series designed around that little Cox production engine. 25" span, 140 squares, profile fuse, full flaps. Whatcha think?

Is anyone else having a problem viewing pictures here?
-
Yeah, here's the deal, I found you have to be registered AND LOGGED ON to view any pics. I don't know why, never saw this particular setup before, but there it is.

That is good. I have the permissions set right. Thanks

Works great for me, now.

Thats a neat plane Ray, way cool. how does it balance with that film canister fuel tank? I have seen only one canister tank in action, and it worked pretty good. I still think its a bit big for an .049 sized plane, personally.
My other question is....like you couldnt guess, how is that Little Ax coming along ;)
he he he

if you are getting sick of me buggin you about it, I'll stop bugging you, for now ;D

Hey Greg,
Nah, you're not bugging me...I'm just glad to see your continuing interest in the LittleAxe.
The film cannister on this plane (LilGeo) is used as a container for a floppy balloon tank. I've found them to be the least trouble with a weak-drawing reed engine. No vents, the balloon just collapses as the fuel is drawn out. Just have to be sure to keep all air out when fueling, and not overfill and begin stretching the balloon...this is not a pressure tank.
Balance on the LilGeo falls just behind the LE, maybe 1/2" back or so. I think that'll be just about right. If a guy was to use a Black Widow, for instance, the nose would need to be shortened about 1/2". And you could throw away the cannister. But this was designed with the "non-tanked" Cox production engine in mind.

Ahhhhh, the ol "ballon in the film canister" trick, clever. I have heard the ballon tank works good, but have not tried it yet myself. Neat that you are making planes for the cheap Cox .049's that are out there. Heck, it might not be prohibitive to sell your kits "ENGINE INCLUDED".
I was wondering what tail weight was required to balance the little beastie, but I bet you have that all figured in. The plane looks good from here, better in the air. cant wait for those pics.
Well, PM me when my AX is ready for shipment, Thats gonna be awesome.

No tail weight, Greg, I try real hard to get the nose length right on my designs for balance with no added weight. Usually hit it pretty close; if a different engine is used than it's designed around , of course adjustments have to be made then. I just hate to add static weight to a model.
Hmmm, I hadn't thought of doing the "engine included" thing...might be a possibility there. "Everything you need to fly included"--lines, handle, engine...Cox even used to include a battery and 1/2 pint of fuel. I think the old Jim Walker Firebaby did too, first plane I ever owned. But then you get into hazardous materials shipping. Something to think on, anyhow.

Yea, I agree the haz mat on fuel included would make the idea less atractive. But having an engine installed, Or included, that will balance the airplane would be a good thing for a beginner kit builder.
Of course, this is your project, but I see me buying these for my nephews after they fly thier Cox plastic planes and are wanting to move up.
I tried to balance everything on a plane I built, before it was built, it didnt work out, and it wasted lots of my time. I have enough of everything, except money and time. and I can do without money, well, no, I cant, but I wish I had more time.
I'm babbleing, time for bed, midnight shift can get in the way sometimes.
