Needed help deciding on new airplane

The SIG Akromaster is also a good choice: simple, inexpensive and easy to build and fly.

SIG Akromaster

I agree with the akromaster. Good cheap kit. No full size plan but there's not many parts so you can easily trace the out lines OR photocopy the parts sheets.

Jim

Fast Eddie (Lazer Works) has a short-kit for the Jetco Shark .15 that includes ALL the shaped parts (you provide the balsa sheet and hardware).

Mine is still going strong after several years, though it IS a bit over-powered with the Enya .19 that's bolted to it's nose, so it's mostly a hot dog-show off plane.

Also, Ed doesn't include plans, but they CAN be found and I'm pretty sure that I can find my set if you decide on this plane.

I have this in PDF, but cannot post it on this site --- can email if anyone is interested.

I'll give it a little time but I trust you guys in knowing what is and is not a good flier . I have a shoestring and another 29 size model that need moving around repair , but take longer lines and my field doesn't have that room + I need fling time before going there . Will this model fly right out of the box or will it need mods.to get it right ???  Eric

If you order two from sig shipping goes way down.

Eric, the Akromaster is completely capable of flying stunt. The only mod I would recommend initially is to sweep the gear slightly forward. I just sold mine recently so I can't give you the dimension I used. Many stunters have the wheels just lined up on the leading edge. I would move the wheels forward 1/2" from there. If not, the plane trips over it's gear on landing and flips over. Engine choice is critical. The Akromaster was designed around the old Fox  .15 and not a modern .15. I always wanted to use my Cox Medallion .15. If the modern .15 like the OS  LA is to be used, I would certainly add an additional rib bay on the inboard and outboard wing. This is also going to require about 3/4 oz of tail weight. Tanks are another consideration with the Akro. You don't have much real estate on the nose between the back of the engine and the leading edge. A 2 oz. tank would be sufficient, but many times it's going to require some plumbing changes especially if you choose a wedge due to the fuel pickup being directly into the back of the cylinder head. It would be much better to re plumb the tank with the pickup exiting the bottom and plug the pickup hole where it exits the front of the tank. This also keeps the fuel line very short rather than looping down the back of the cylinder and back up into the spraybar. That is always a major flaw when routing fuel tubing. Somewhere through the run, the engine is not going to be happy. This is usually overhead maneuvers. The end result is not a good one. Ken

Just curious about your engines Eric.. Is the OS a .15 FP-S? I think OS made one.. and the Fox.. is it the older .15 Like I have?

Here's my Fox .15.. I have second one of the same vintage that needs a piston.

That Fox is the .15 X slant plug. I like those engines and they work very well when propped with a 7" prop. I like MA 7x6's and APC 7 x 6's. Let them wind up and go. Many don't like the Fox .15. Certainly not Fp power, but they're very light compared to a FP. Good power for a JR Flite Streak. Ken

How's the Shark as a stunter? I've never flown a Junior sized plane, and I have Thunder Tiger 15 that needs a job as well as a Tee Dee .09 that I've never cranked.

I'd imagine that one properly built, would be a great plane. Mine is powered by the Enya .19, given to me by Wayne, is rather fast. I just hot-dog it around without any serious pattern work...

Is this plane going to take a handle with a 3" line spread ? I hope to get soon and get started on the build , maybe get in the air before it gets too cold , Also PM sent to Andrew for plans for the Shark15 I would have rather had a built up wing but this will build a lot faster  Thanks again everone . Eric 's Christmas Present to me  

You may find the .015 lines a little draggy. I like .012's for .20 or less engines.

I agree, but keep the .015s, you'll be needing them sooner or later. The AMA rules are overkill, at least according to the FAI. They fly the big ships on .015" lines.

Akromaster with Cox Medallion .15 on it. Seems to pull well. More like the pilot is like me and doesn't want to break the plane doing stuff he's not comfortable with.
