A B29 model powered by 4 chainsaw engines... Complete with a mid-air
launch of an X1 rocket! Here's where a lot of work pays off.

http://users.skynet.be/fa926657/files/B29.wmv

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. 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.

I made a boat powered with a weed eater motor when I was a kid. It was
a lot of fun!

Theres' several vids on u-tube that show 'em. That is kinda cool. I'd
thought of it also, but eh, too many other projects.

I saw some R/C boats at Perry, GA at a R/C swap meet and show they
have there every year. There are groups that race them, and some of
them will do 70+ mph. There was a guy that was selling one a few
years back that was a twin-engine model, and it had been clocked over
100mph.

I looked into it thinking it woiuld be fun when we're out on the
lake. Up in a quiet cove, fire up and toss out an R/C boat and let
'er rip! They do make smaller electric powered ones that would be OK
and the costs are reasonable, but one of those gas powered fast ones
can approach $1000 real quick.


Thus fulfilling the prime rule of boating...POAT...peel off another
thousand.
