Hello,
I have spent a lot of time flying in real helicopters (A-Star, Bell 212, Jet ranger, H500 and Alouette III) while heliskiing. I really enjoy the flying in helicopters, so I have been thinking of getting into RC helicopters.

I recently picked up a copy of RC Helicopter magazine. There's an article about "30 Choice Choppers for all skill levels." The artical seems to cover most information you'd want to know before making your first purchase. But, I'm wondering about buying a micro RC helicopter, because of where I live. I live up in the mountains outside of Denver. My house is at just under 8,000 feet. Is this too far above the maximum operating altitude for these machines? Any info would be appreciated...

Thanks,
HJ

I dont think 30 is "micro".. but i have a raptor 50 and i live in Durango and its at 7400 feet and i fly fine with a os 50 hyper in it.

But you do loose alot of power with more altitude, i flew down in albuquerque a couple weeks back which is 1000' lower and heli had quite a bit more power..

But still 8000' is flyable...

Osiviper, I think he meant 30 x heli's that they recommended, not a 30 size.

For the love of the hobby

I don't think the electrics would suffer as much from altitude as the recips. Electrics would have to put up with the blades spinning in thin air. Recips have this problem, plus reduced horsepower as well.

If God had meant for man to fly, he would have given him more money

You should be OK at that altitude. Models don't have the same weight to rotor lift ratio as full size helis have. If you have the pitch and power you won't have a problem. Now, the control of a micro could present a problem. They are much harder to control than a larger heli such as a 30 or 50.

Experience is something you don't get until just after you need it!

Thanks for the information guys.

It makes sense that the power to weight ratio of micro helicopters can overcome the altitude problem. I hadn't thought of that.

Of course, colder air tempreture would also help with air density. How does the cold affect these micro helicopters? Does anyone fly outdoors in the winter?

Cold air is denser and it can only help. That is if the motor doesn't freeze. I'm sure someone has tried it. Being from sunny California I don't have that problem.

Well, a Raptor 50 can lift 2 Kg or more at about 1000m ASL.
I think it will scoot around quite smartly on it's own at 2500m.

The cold weather WILL affect the batteries on an electric- and their ability to work. I would think if you kept them warm inside a vehicle immediately before use you may be ok, but cold batteries will not be a good thing on an electric heli.

So.....

Which would you guys think would be better for cold weather and "high altitude" flying, the Eco Piccolo V2 by Ikarus USA or the Caliber M24 by Kyosho corp. of USA?

I once took my old shuttle up to Westcliffe. (not sure of the altitude), but it barely got off the ground with a new os 32sxh in it.

Walk on water long enough, eventually you will get your feet wet.
