A B29 model powered by 4 chainsaw engines... Complete with a mid-air

I've seen that thing fly twice, and watched him crash it once. *After
the X1 landed, he spun the B29 down from way up high, where he'd been
circling while the X1 did it's thing. *Then he flew down the runway
doing slow rolls, and during one of the rolls the outer third of one
of the wings folded up. *That was several years ago, and I understand
it's been crashed and rebuilt more than once since.

The original B29 was built by a guy who didn't get a chance to finish
it before he passed away. *The family gave it to Mac Hodges, and he
finished it and began flying it at RC events.

BTW... those aren't exactly "chainsaw" motors. *They are purpose-built
for RC aircraft use. *The current B29 has four DA-100 motors that are
twin cylinder, 100cc and cost $1000 each. *Yes, with all the motors,
radio gear, and airframe it's probably $6000 - 7000 in the air. *Just
the props can be over $100 each.

Here's the motor used: *http://www.desertaircraft.com/engine...hp?Page=DA-100

I passed on the info as I recieved it.

Thanks for the correction.

It was not meant in any mean-spirited way. *

Deffinately understood.

How would you know unless
you were into R/C? *Besides, many R/C planes acrually *do* use
converted chainsaw motors... they just aren't as light and powerful as
something like the DA motor, but are a whole lot cheaper! *And gas&oil
mix is far less expensive than the glow fuel that the traditional R/C
motors use.

no I haven't been into the model air plane stuff since I was a kid.
Some where around either my brothers place or here, we've got a box of
04 cox and wen-mac engines left over for destroyed string fliers.

we never could afford to get into RC

I've thought about it, as I used to do a lot of u-control modelling. But a
friend who is into it has had a rough time finding a place to fly around here.
He's got to drive a long ways to find a place that allows RC flying. It used to
be that almost all the military bases had an RC club. Don't know what happened
to them. Nowadays, if it doesn't have a touch screen and show videos, the kids
aren't much interested.

There are some really nice electric park flyers and slightly larger
electric planes that can be flown in an open field or even a large
parking lot. The new electric motors and speed controllers, along
with the new battery technologies, have made the electric RC airplanes
perform very well, and they are nearly silent.

The biggest barrier to the big gas or glow fuel planes is noise. I'm
a member of a club with 80 acres out in the country, and we can fly
what we want, but we still always run mufflers on everything and are
aware that flying sites can be taken away in a flash. It's an issue
that everyone is dealing with.
