I've been doing some indoor flying this Winter using gear from Plantraco. The radio is an HFX900 tx is on 900MHz with the speed control built into the rx.

The first pic is the radio, rx, motor and actuators. The Mustang is from Plantraco as well, it flew OK, but was a bit quick indoors and I didn't care for the profile foam look.

The last few pics are a plane I built to use the gear from the Mustang. It has nearly twice the wing area and weighs 8g without the radio gear - 14g flying weight. I plan to try it out tomorrow.

The last pic is with a COX .049 product engine for size comparison.

Nice looking model, if the direct drive motor/prop combo is not up to it, Hobbyking has some nice 6mm and 7mm motor/gearbox combinations also a 3.9gram brushles/gearbox unit for larger indoor model all at reasonable prices.

Thanks for the heads up. I know what's going to be added to the list next time I place an order from Hobby King.

Arent they a blast. I have the Butterfly and with just the slightest breeze I can make it hover LOL

Now that is pretty cool.

The Plantraco is stuff is pretty small and lightweight. There are several local fliers using their equipement. The new 2.4 ghz reciever/servo blocks are making these micro fliers even easier than it was even 5 years ago.

Here a couple of photo's of something I built about 4 years ago so it uses "older technology".

Wingspan is about 16 or 17 inches (I think) and loosely based on the "Double Whammy" penny plane design. Power is a motor from a Zip Zap RC car geared about 5:1 or there abouts, the prop is mounted on a 1 mm steel shaft that runs in 2 1mm ball races (contained in the black carbon fiber tube alongside the motor). Prop is carbon fiber and about a 5 x 3. Battery is (was) a then new 90 mah Lipoly and control is motor and rudder. Radio initally was a "bang-bang" arrangement made from the RC unit from one of the micro RC cars and later replaced with a RFFS-100 (no longer made) on 50mhz.

The design is grossly overpowered and flies at a fast walking pace at less than 1/2 throttle.

I called it Sixpence as it's all up weight is a wee bit less than 6 pennies (about 17grams). Construction is all balsa - rolled tube fuselage, stick and tissue wings and somewhat over built, 3/32 square for much of wing structure just to make it a little more robust for our rather rough air indoor flying site.

Still flies very nicely.

cheers, Graham in Ottawa Canada

So Bipe how does it fly ?

It flies, but a gearbox would really help a lot. I tried a few props and not surprisingly the largest diameter/lowest pitch flew the best. It's kinda cool that it will ROG on cement though.

I'm gonna order a few of those gearboxes from Hobby King when they're back in stock.
