Toy 2-LED Dragonfly for V911 night flying.

SIZE: The propeller part is the same diameter as the V911 blade diameter. The blade hub slides firmly down over the V911 flybar.

LEDs: Easily disassembled by gently pulling the plastic pieces apart. The electronics are two LEDs, one on each side, a core of three AG1 Button Cell Batteries (alkaline 13mah), and a very strong eyelet screw that turns into the batteries connecting one set of LED leads to the battery. Eyelet screw switch works very well to turn LEDs on and off, so precise it can even be set to switch on vibrations.

The LEDs are parallel with the battery and are actually blinding at arms length. They are the floodlight kind, 4 inch circle at 1 foot distance, another 8 inch circle at 10 feet, 3.14 volts across the LEDs, eyelet is (-). No resistor. Non-blink blue LEDs on the one I pulled apart. Two LEDs lit, no heat.

Each LED (+) end will slide out of the plastic leaving the other LED still functional. Each LED (-) end unwraps from the eyelet with a half twist.

NOW THE GOOD PART.
The LEDs must have internal resistors because they work fine across a V911 stock battery. No heat, just blinding light. And no damage if you connect backwards.

So, for $0.38 each, you get two floodlight LEDs with internal resistors and a 3 cell battery. Tape a few of these units to the v911 for night flying and when the battery is dead, wire the LEDs to the LiPo 3.7 volt battery.

Have not timed them, likely will last at least...Continue Reading

FS-CT6B Transmitter with V911 Helicopter
http://www.rcgroups.com/forums/showp...postcount=6240

The FS-CT6B transmitter is a cheap way (about $35) to try something other than the V911 stock transmitter.

One place has pre-order for $27 (Stock: -1017) buy Mode 1 or Mode 2 versions. "4-Model Memory" actually means "4 Mode Memory" as in Modes 1,2,3,4 selectable. No "Integrated timer". No "Contrast Adjustment" - no contrast to adjust.

It does not have Rudder Expo.

It does not have digital trim tabs. But the manual trims can be set instantly without delay and without looking at the transmitter.

This transmitter requires a PC to modify any of the channel variables, including mixing and servo reversing.

It takes eight AA cells. But may have more output power than the stock V911 transmitter.

No model memory. With a computer, you can save and load model types quickly.

On the good side, you can actually buy FS-CT6B transmitters and they are easy to program with little knowledge about how to do it. You can also fly the V911 to see what changes do while programming.

Posted here are my latest settings for the V911 and I am starting to like this FS-CT6B with the V911.

Rudder is set for about 50% of stock. Smooth rudder control that works well with the crazy way that I fly (wind surfing).

The two knobs control Elevation and Throttle starting points anywhere in the full range.

I set Throttle knob to just below...Continue Reading
