Title: What might be an ideal electric
Post by: jim gilmore on September 18, 2010, 09:12:35 AM
I think I've got the ideal electric profile in mind. Even as a half a model, I'm considering a scaled down carl/goldberg shoestring . Scaled down to 28" wing span the nose cowl will work as a place to bury the battery. and I thinl It could even take a 7 inch prop and work to take off and land without the prop hitting the ground.

i'm reffering about a profile shape that gives a place to hide the battery an such.

the Ol Tiger would also be good for that

edit: should be Big Tiger

Not sure why the tiger , or shoestring have such cowls.
Were these aircraft that had opposed cyclinder engines ?
But seems that the wider fuselage nose would be good to hide the battery and equipment.

one thing to keep in mind, if you put the battery on the inboard side of the fuse, you will have to add extra tip weight to compensate for that hunk of electrons on the inboard side. On my Profile, I put the battery on the outboard side of the fuse and actually did not need any tip weight at all, works out to a savings of a couple ounces over all. Just something to keep in mind

but if the battery runs thru the fuse sois shows on neither side ?

Jim in a profile plane there are a lot of vibrations from the IC motor due to the flat fuselage. Those cheeks create a good way to dampen the vibrations and add a little bit of personality. It happends that now it will make a good way to hide and control the air flow to the battery and the electronics.

The shoestring is based on a real racing plane. But I'm not sure why the real plane had cowls that way?
There are a number of real racing planes that had the configuration.
The shoestring,cosmic wind,cassult special,sharp nemisis,Zivko Edge 540 just to name some that I see.

Flat motor configuration.

I finished a profile electric model about two months back and done just that, its and Eze-Pro from Keith Renecle, I just modified the fuselage to look like a Yak and made a semi cowl as you can see in the pics

The "Goodyear" designs were built around the Continental 0-200 4 cylinder opposed engine.  These designs
were built for the then new class of Formula One. 300 plus mph with a 100 hp engine.  Sponsored by the
Goodyear tire co. in the 40's...after WWII.

Lionel,

That is a neat looking model!
