It is just some tank from an old kit. What is the exact width and height of the opening. If I recall The tank for you plane is close to 3" wide and about 2.5" high but is is installed on edge.

The opening to move it up forward is 2.5"wide and the it's 3.25" high. The "bay" in front of the wing tube is 5.5" X 5.5" and approx. 4" high.
I can find one to fit if I lay it on it's side but, afraid it would leak fuel in that position. Was your's that way?

If it will work an Aeroworks 750cc fuel tank is 3" x 2 1/4". You can phone Jeff or Mark at Aeroworks in Colorado and they could get one to you allot quicker. It will come complete with gas stopper, cluck and brass tubes.


BTW 750cc is about 25 oz.
Hey, that looks like what Ineed. Doesn't look like it cares whether it's on it's side or laying flat.

The AW tank will work perfect for you. It is around 6" long. It is supposed to go throught he former into the next bay in front a bit. Give AW a call and the tank will work just right. It doesn't matter if it is on it's side or not. They can be installed either way. Ph 303-371-4222 Here is a link. It is not exactly like the one in the picture. The one in the picture is a smaller rounded tank.

I've tried to order that item a few times but, it won't go in the shopping cart. Guess I'll have to call them tomorrow.

Persistance pays off. I completed the order and will have it next week.

Thanks for all of your help. I'd still be pulling my hair out without you.

No problem, enjoy your plane. A guy I know has one and it is one of his favorites.

Which engine is he using? I've decided to put my DLE55 in a 30% Edge 540T instead of the 25% GPYak. I think it's too much engine for that bird. It's too nice to shake it apart and over-stress it with an oversized engine. I'm thinking a 30cc engine with about 4hp should do the trick for IMAC but, curious as to what you're buddy is running.

Thanks,
Garry

He has a MT 50 in it. Quite a bit less power than the DLE.
