Either 11T or 12T will probably work ok, you just need to find your preference. With less oxygen to your brain though, it may be tough to make the right decision.

Ok, since we are talking about too little oxygen (living in Colorado Springs) I need this explanation spelled out a little slower. Sorry, I have a double whammy. I used to live in Alabama. yea, I know.

So at 6,000 feet do I need more head speed or less head speed for my novice flying skills? I really do not need some super 3D acro heli. Just one to hover around my house without killing someone.

Not too sure since I'm also new to helis, but usually when flying planes people will increase the pitch of the prop at higher altitudes. At higher altitudes, the air is much thinner. You're going to need more "bite" into the air to achieve what you can at sea-level. You can achieve this by increasing pitch, choosing longer blades, or increasing headspeed, or a combination of all three. Just experiment with these options until you hear from someone who has tried out high altitude heli flying. If you mess up with these options, and your heli can't even get off the ground, well then you really have nothing to worry about If your heli feels a little sluggish in main blade pitch, like when you jam the throttle up and the heli doesn't immediately climb, then you'll probably need to change your pitch curves around so you have some more bite into the air. If you find you need more than 12 degrees of pitch for any given situation, I'd try increasing the headspeed. You don't want to go with too much pitch because you don't want the airflow separating off the surface of your blades. At roughly sea-level, I'm hovering at about 3.75 degrees of pitch, with 2700 RPM headspeed.

anyone flying this with the HK 6ch.also should i keep the endpoint of the servos 100 or backing them down a little.i just want to hover for awhile.
i added the flybar weights does this help any for stabilaty.sorry about the 20 questions.
i see they have the all metal now i must have got lucky and they sent me one by mistake

Karl,

I live and fly at about 5700- 6000 ft. It'll fly fine with about 27-2800 rpm headspeed if you're not trying to really throw it around. I find it more stable at about 29-3000 though. Also more responsive with a higher headspeed. Not as mushy. For more stability, leave the flybar weights out as far as they go on the flybar. For more manuverability, take the flybar weights off.

I used to live at 9300 ft. and work at 11000ft. This air is pretty thick down here....

Mountain sherpa?

No, I worked at a hydro electric plant in the mountains. Now I work only a mile hi, in Denver (hence the move down here too) but I fly at our club near the foothills which is a little higher. Never flew anything way up there. I'll have to try it one of these days.

I found some great setup videos for the HK (or other FlySky re-labeleds) 6 channel 2.6 GHz radio and a Trex clone like the HK450: http://www.mikeysrc.com/Low-Cost-450-Heli.html

thank you, this is GREAT information. I am right at the point where I needed this.

I just got done with my first hover and used these videos and the manual for a first time build for me. Not sure what I would have done without these videos .

I used an simple rate gyro (PG-03) I had sitting around and it worked ok but didn't stop the slow drift, still an easy hover though. I'm waiting for my HH gyro before I attempt any real flying.

I ordered the MT version with the Typhoon 2215H motor just now. Should be a fun winter project getting my head back into CP setups. Maybe since this one cost less than one lipo did on my Voyager E, my knees won't knock..... Now to sell my mCX

which battery are you using and what flight times are you getting?
this is my fav motor but it eats amps

I use the Zippy FlightMax 2200mAh 30C packs. Hovering and flying circuits I fly for 8 minutes. I've never had to put back more than 1650 mAh into the pack. When I fly fast and do sport aerobatics, I'll fly for 6-7 minutes.

that's pretty good, i'll have to look into those flightmax. i get about 4-5 mins

20C 3S 2200mah $15.00 turnigys with the Typhoon 2215H and 11T pinon, if I'm just hovering around I can get about 10 1/2 mins of solid hovering with little power loss... I fly for about 8 mins of sport with mild 3D (couple tictocs, flips, inverted, piros,etc..).

Nice flight times. What is your headspeed?
