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.
