It was windy, about 15 mph winds, and it was cold, about 30 degrees, but I figured what the heck, if I crash it, I will have all winter to rebuild, so I went for it. I had 2 808 cams on my hat and one onboard the T-rex. The video plays them in series, then all in sync.

I was amazed when I saw how small some of these heli's were getting. Sure the 2 channel IR birds were small, but they weren't that controllable without any cyclic. I was intrigued by how small these things may actually get and still be controllable. I bought the Gaui Hurricane 200 when it came out and was pleased that a bird this small still flew as well as a 450 (which flew as well as my .30 nitro birds). I then found the Walkera 64#C, which was even smaller than the Gaui. I think this was the start of my collection and from here it grew pretty quickly. Here's a list of the current birds in my collection, they are pretty much 4 channel and up, no co-axials:

Kyosho Minium Caliber 120,
Walkera 4#3,
Walkera 4#3B,
E-Flite Blade mSR,
Nine Eagles Solo Pro II,
Precision Heli Micron V2,
Blue Arrow Dexterity V2,
Walkera 4G3 Double Brushless,
Walkera 4G3 Custom Double Brushless,
Walkera 4G6,
Walkera 52,
Walkera 64#C,
Walkera 64#C Brushless,
E-Flite HoneyBee CP2
Ele Firefox EP100,
SJM 180C,
Gaui Hurricane 200,
Copter X 200,
Align T-Rex 250,
Art-Tech Genius 250,
Guanli GL-EP200,
Skyartec Wasp V4,
Align T-Rex 450SE,
Align T-Rex 450SA,
Wing 450 V2

I've got a bunch of coaxials too, like the walkera 38, and some of the micro's too, but I still consider those toys.....

I remember seeing electric helicopters back in the '80's, like the Skylark and later the eco and the kalt. The technology didn't come of age until the introduction of brushless motors and LiPo batteries, and now electrics challenge nitro as a source of power. I was intrigued and wanted to try electrics.
I became hooked on heli's again around 2006, and picked up a T-rex 450 and a DX-7. I was pleased with the quality of this heli and radio for the price. It already had the cnc aluminum and carbon fiber parts that I had paid hundreds of dollars for on my nitro birds. I picked up a back up rex too, and then got a clone 450(wing) at iHobby for cheap just as they were closing down the show and the reps didn't want to take it back on the plane with them.

The Hirobo Shuttle ZXX was highly upgradable, and tons of aftermarket parts were available in anodized CNC aluminum. Wood, carbon, and glass blades of all types were available, as were canopies. I used a G10 frameset from Hel-X in my main Shuttle since I put a O.S. .46H in it and the composite frame was really designed to only handle the loads from the O.S. .32H. By the time I was done adding fast servos, Piezo gyro, and digital tail servo, my shuttles were worth almost $2,500 each. I prefered lexan canopies over the plastic stock shuttle ones, and the Ninja shaped ones were my favorite.
Although I flew my fixed wings with Futaba for over a decade, when I got my first heli radios, I switched to JR, starting with the 622, then the 347, then the 388. Heli's require more transmitter programming and I found the JR radios much more intuitive to program resulting in easy field programming.

Around 1992 I purchased a Hirobo Shuttle kit and put a .28 with a tuned pipe from my chipmunk and my 4 channel airplane radio (with y connector joining the collective and throttle servos) into it to learn to hover. Now I had a Gyro! It actually had a spinning gyroscope inside but worked well compared to my SuperMantis experience. I learned to hover little by little. I upgraded the engine to a Supertigre .34, got a JR 622 radio, and a Piezo gyro, and started to progress. I soon bought a Kyosho Concept 10, a cool little heli with a pull start, but not near as stable as the 30 size Shuttle.

Well I started flying heli's about 1983 when I bought an American R/C Helicopters Mantis .40 along with the upgraded collective pitch rotor head (essentially a SuperMantis). I used my K&B .40 and my Futaba 6channel from my GreatPlanes/Bridi 15-500 to try and fly it. I had no gyro. I bought the Heli-Ball muffler thingy after my blades got soaked in oil from the exhaust. I was able to get it in the air at least once, and at the most for about 30 seconds before losing control. Every change in throttle stick would cause the tail spin and I would lose orientation. So I sold it after a season of messing with it, and continued to fly airplanes until about 1992, when I got back into helicopters.
