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.

Don't through away those old motors. Some are collectable, although
they aren't really worth much.


we never could afford to get into RC

The radio gear was expensive and finicky back then, but is amazingly
cheap and bulletproof now. I was in the same boat as a kid.


The one time I got my U-Control balsa and tissue model airplane in the
air I got so dizzy I puked. This was when I was 12 or 13. Were there RC
flying models in those days? I don't remember them.

I flew a lot of U/C back in the day. I started with the little string
line 0.049 Cox motor planes, and graduated up to stainless steel lines
on 50" wingspan stunters with Fox and McCoy motors at just under 0.50
(yes, 1/2 cubic inch) motors. I still have a couple and fly them
occasionally. The R/C guys just watch and shake their heads. :-

There was R/C back in the timeframe I beleive you're talking about,
but it was experimental and rare. Guys had to build their own
transmitter and receiver equipment in the beginning, and the control
was crude. It took the transistor becoming common and cheap in the
'60s to have multi-channel, proportional control equipment, and it was
very expensive.

Now you can buy a nice 6 channel R/C transmitter and receiver with 4
control servos, rechargeable TX and RX batteries, and a charger for
around $200.
