RE: Baby Bee ARF by Clancy

I have one. It IS small enough to fly indoors however mine has only seen the outdoors. In stock form, it was really lacking in power. It took a while to gradually climb high enough to attempt some...

RE: RX Ant. Length

The formula is 2952/Freq (in MHz) = 1/4 wave antenna in inches. The wire size doesn't matter because there is immeasurable current flow in the wire. The antenna may be wound around a non-conductive...

RE: CELL PHONE BATTERIES

Tom91,
If you are charging those batteries straight off of a wall power supply with no Li-Ion charge sensing circuit attached, make sure those batteries are outside, on a non-flammable surface and...

RE: Floats for a micro heli

I was thinking of that too. The plan was/is to use some styrofoam rods (probably around 1-1/2 to 2" diameter) and mount it to the skids on the Hummingbird. I haven't been able to find any styrofoam...

RE: Futaba 6xhs

I am using that setup. I modified the GWS receiver to add channel 6 for a CP heli... No problems at all. Besides having both RX and TX on the same channel, make sure the receiver you have operates...

RE: Hitec 555 and Futaba 8uas CCPM

The pitch servo for CCPM is usually on channel 6. Unless you can change the assignment in your TX, the 555 won't work.

RE: Dragonfly main motor alternatives?

I have been using a 6V Graupner Speed 300 for months. It's still going strong. Rather than re-time the thing, I just hooked up the wires backward (red-black, black-red) at the motor. Probably...

RE: Fead Dragonfly Li-Poly?

Yes. I had to move the Li-Polys a little forward to maintain CG. Work out well however. Set at that angle (which it just naturally falls into), the batteries tuck nicely under the canopy. ...

RE: Fead Dragonfly Li-Poly?

A 2 cell Li-Poly pack (2s) measures 8.4V. Just right for our little birds. Here is how I mounted my Li-poly pack: http://www.sparerib.net/pix/batt1.jpg. Many of the hobby suppliers that advertise...

RE: Fead Dragonfly Li-Poly?

jarose,

For charging a 2-cell pack, a 12 volt power supply should be sufficient. I use a 12V 2A bench supply for my 2-cell packs and it works just fine. Look at...

RE: Hummingbird - Mind of its own...

Is your transmitter on and functioning? Glitching of that sort can certainly be expected if the receiver is powered up without first powering the transmitter...

RE: Humming Bird goes outside.... (then bits fall off...)

I had the same thing happen one time. I used a small drop of CA glue on the replacement. So far it is holding fast. I do check it periodically just to be sure however.

carbon fibre

Carbon fiber is strong however it is brittle if it's properties are exceeded. The stuff I got from the kite shop appears to have linear fibers(all laid in a row from end to end) where as the stock...

There is carbon fiber and there is plastic (of one sort or another). To replace my landing gear struts, I went to a kite shop and bought some 2mm carbon fiber rod. This stuff seems tougher than the...

I believe he is talking about changing the rudder from right to left stick. The only approach I can think of to fix the aileron stick is to go back through your work. Heat may have melted a couple...

How did you mount your Li-Polys on your HB??

If you scroll a little further down the page on the link provided above, you'll see how I mounted my Li-Polys. My canopy fits fine and you can't even see the battery when it's on. Better yet, it...

Feda Spins CCW

I have had to put a small drop of light oil on both ends of my tail motor before. I have had the bushings dry out (or collect enough dust) that the motor couldn't reach full speed.

You might also...

Main rotor and Tail rotor balancing on Hummingbird

Feda Pitch Problems

Good. Then try this: http://www.rcuniverse.com/showthread.php?s=&threadid=956784&forumid=185. BTW, no. You don't jam the throttle. Ease it up and gradually lift off. A little bit of right roll...
