LFO's (lightweight flying objects)
Jim,
I've returned a couple of these helicopters that were bad out of the box.
One wouldn't get out of ground effect no matter what. The other wouldn't
trim.
The little biplane is fun, though, and I can fly it in my hangar. It can
even crash into a 1/1 scale ASH26E with no apparent damage to either
aircraft.

Bumper,
The batteries were in great shape. I did the nose weight routine, but
that was not all the effective. It would try to move forward, but the
stabilizing effects of the rotor fought it. And if it did move forward,
it lost the hovering capability.
I had actually bought this as a thank you gift for a buddy that's letting
me fly his J-4. Now that he's bought abouth 4-5 other helicopters, all
improvements over this one, I'm going so see if I can get the old one from
him so I can rip out the innards and migrate it to an indoor penny plane
design.
Amazing to think that we even have these micro miracles. Just five years
ago, they were a dream. I can't wait to see what the next two years
bring!

There are three ways to gain forward flight. Add about 2.5 grams of
weight to the nose, twist the tail rotor clockwise maybe 10 degrees
(looking from the rear), or add a "canard" sort of wing at the front and
the downwash will tip the nose down. I did the first two.
As to no cyclic, what do you expect for 30 bucks? I'm amazed it flies!!

I bought one of the helis. It never went into forward flight. The
aeromechanics are pretty lame. There is no cyclic, so no way of inducing
real forward flight, especially since the Bell Hiller rotor head promotes
stability. Later generations now have little props, similar to a
blimp's, to provide forward motion.

Or what to do when the weather says, "no soaring".
For those who don't get out enough (no rude comments directed towards
me,
please), you may not have heard of the following aviation related
items (no
financial or other connections with this, but they sure is fun!):
"AirHogsHavoc" helicopter
"AirHogsAero-Ace" plane
Both are $30 or less, and available at Wal-Mart, or Target, or maybe
on-line. Wal-Mart seems to sell out quickly but they restock just as
quickly - - these items are going like hot cakes.
Both are powered by a built-in lithium polymer rechargeable battery.
The
transmitter / charger is powered by 6 AA alkaline batteries (I'm using
NMh
rechargeable in thehelixmitter with no problems).
Theheliis recommended for indoor use only, has an infrared remote, and
is
great for strafing the wife in the kitchen while she tries to prepare
supper. Remote controls up/down (main rotor speed) and a tiny
anti-torque
tail rotor is both trimmable and provides turning control. Theheliwill
hover still with little forward movement as received. Putting a small
weight
under the nose (included) or slightly twisting the tail boom clockwise
(looking from the rear) about 5 degrees, will provide forward speed
(though
thehelidoes not go fast enough to go into transitional lift). The IR
control can be overwhelmed in bright sunlight, so it really is an
inside
toy.
The Aero-Ace biplane is also lightweight and can be flown indoors or
out (in
calmer wind conditions). Remote is RF (27 Mhz) and if signal drops,
the
planes two counter-rotating props will stop. Remote control provides
up-down
through an increase or decrease in throttle, and turn by
differentially
changing prop speed. It's easy to fly as well. Like theheli, the light
weight means you can do multiple crashes with no damage, though I
recommend
releasing the throttle when you know a crash is imminent!
Oh, and please remember, "You only grow old once . . . but you can
stay
immature all your life!"
