    Status: offline     		Cold weather can affect the plastics and other materials (making them brittle) , will lower the output of the battery (effectively a moderate to HUGE reduction in capacity + voltage under load (really the latter but effectively the former)), can alter the fit of pieces due to different coefficients of expansion for various materials (aluminum vs Glass reinforced plastic vs steel (tail, frame, screws effectively). The cold can and will also alter the viscosity of various lubricants, cause humidity issues with wood blades etc.

    I tend to fly a lot in the cold but haven't had a lot of experience with the 36 yet. I have found that I needed to progressively tighten the belt as the temps dropped and lower my flight times as the power fades quicker. Almost any flex in plastic will turn into cracking and breaking at -30 deg c more often than not. Generally though I haven't had a lot of problems flying my hummingbird or various planes when it is cold out other than the odd cheapo prop destructing due to flex (and that was relatively rare).

    I am concerned about the 36's belt loosening at the cold temps, the GYRO being very hard to temperature stabilize w/o taking it out of spec in the cold temps (I don't believe these are rated anywhere near -30 deg C, probably more to -10 if anything but I should check the manuals again), and in general an increase in resistance as all the lubricants stiffen up. The lube issue may be resolvable by finding a suitable "dry" lube that has a broad temperature range (to the downside).

    One last point is that it can be hard to keep one's fingers warm enough to fly while having enough control on the sticks Often this is the first reason for me leaving the field; the need to warm up!

    P.S. - Has anyone checked the workable temperature range for commonly used adhesives and loctite?

    ..what kind of consequences are you lookin at??..


    I go along with what thecheatscalc said, plus the plastic would be brittle so more damage is likely in a smaller crash.

    Status: offline     		It almost makes you want to overload the battery to keep it warm in the cooler weather...


    OK now I've decided it's time to replace my mangled tail boom. What is the CORRECT legnth, and will a trex (XL / non XL) work? also would a shogun V2 tail shaft work? hmm and where can I get a titanium main shaft? I'm thinking about making/inventing a MAGNETIC swash plate as well as a few other parts so it would lessen the blow when the heli takes a hit acting like a shock absorber, plus it never needs lube, and you clean off the magnetic dust with tape. what think ye of that?

    Status: offline     		I would go for the Trex tail components, the 36 is essentially the Trex tail plus the Shogun V2 head with a Walkera body. You may need to trim the tail if it is longer (I haven't broken my walkera boom yet) but all the T-rex tail components seem to fit.

    Status: offline     		Hi all, i have just bought a 36 secondhand. I think the gyro is not working correctly.
    Would someone be able to tell me how to test it, or would it be better to buy a better one?
    And what sort of gyro would be the best to buy.
    Thanks guys Jay

    ok I'll get that then though what should I get for a tail shaft? the titanium looks pretty nice but it doesn't have holes in it (trex) like the walkera one... oh well, I'll look into it I bet they're the same legnth anyways.

    but i have been reading all your posts keeping up with ya.
    Hi mate I have a bad walkera gyro two, it is very sloppy oneside of the stick.I can spin the tail round easily one way not so easy the other it seems slow to return to center.I have disconected the gyro and the tail seems fine and the tail servo worksfine, so i am sure its my gyro.I am looking to buy thr 240gyro as people seem to talk high of it.

    Who else has had this.

    Status: offline     		Good question as I was thinking of buying a new gyro as well, didn't get the copter yet but want to start the upgrade list ahead of time, what is "the best", and most stable gyro that will work with the 36?

    Have you hover without using the gyro? I never did it and wonder how it hover without using the gyro, is the tail steady or very sensitive?

    Status: offline     		I put a futaba GY401 on mine. and have never looked back. The tail lock is superb! I can place the tail right where i want it and it stays put every time. I can violently reverse backwards and the tail is still locked. This is my recommendation if you have the bucks.

    Status: offline     		sounds good to me , maybe it'll prevent some crashes and up my learning curve lol
    Any suggestions on where to get one for a decent price?? and preferable in US or Canada.

    yes I have hovered (and do) without a gyro, it's not that hard as a gyro is usless without tail lock anyways. yes it's a little harder to handle, but I tell you it's worth it. the tail IS more sensitive though so it takes a little more of getting used to, as well as putting the arm to the lowest hole.
