Status: offline 		Ok, so I listen to everybody and upgrade the lipo from 7.4 to 11.1 on my #36, setup my rd8000 to be right and have been flying the 36 for about 12 flights with nothing but good times until now, My headspeed at hover is about 2300 on the tach and max out full pitch is about 2700. Well I'm just hovering around with my 36 (full metal head w/ swash) and all of the sudden I see parts flying in every direction and a blade goes winging by my head. Apon post crash inspection, the cross shaft for the grips broke after the main body, there is no vibrations on this heli and the blades tracked perfectly. So I would say this turd really can't handle high head speeds for long before something gives, unless the shaft was defective I really don't trust the aftermarket parts or this heli running at those speeds, I'm putting the motor and esc into the mx400 and someday put the 36 together or in the trash. I don't see taking the risk of injuring or seriously hurting a bystander by flying this junk,in the process of trying to make it work properly. The parts seem to be too sub-par that it's a hazard to anyone flying one. Why should I waste more money on this heli when it has nothing really going for it except constant repair or upgrades, so far I guess the only origonal parts on it are the frame,gears,tail and landing gear, all electronics and head parts have been upgraded and it's still not reliable enough to fly more than 20 times without something giving.
Just my 2 cents

Status: online 		i know exaclty what you mean, these heli's are very cheap and with the speed the blades go on these, a heli is the last thing you want to be skimping on quality, ive had a pair of cheap blades snap and im lucky i didnt get hit. My WK60 is constantly falling apart to the point where im not going to bother with it anymore and just get rid of it cause it might self destruct mid air, not to mention the cost of parts just to keep it flyable. I tried some slightly larger blades on it that were a bit heavier than what id been using and after a very short hover it all went wrong, im not exactly sure what happened but the blades went out of track for no reason, and the metal head has started to loosen up and wobble in places where it just shouldnt, so the heavier blades must have started pulling it apart.
After seeing a trex450 for the first time, i see that the quality on the walkeras is shameful and not worth the bother. I have spent so much money repairing my walkera without having even crashed it, the trex just keeps going and going without any sign of wear.

Status: offline 		I hear you, I went to put the spare main shaft back into the #36 and straighten out all the parts but then realized that the main shafts are longer on the stock heads from the aftermarket, and after refitting the shaft and getting it all balanced in the same set-up I had before, I realized the slot in the main is in a different location. Now I have to readjust everything back to zero before I can try this turd again. I don't know why I even bothered fixing it. Maybe I'll just shoot it up to 200' and try going inverted to see if it self destructs. The #36 is a good stable heli to learn on, but when your skills exceed the heli's ability, forget it, buy a real heli and save yourself the money you'll dump into a sub-par walkera heli that will never fly the same two times in a row. I have a MX400 I'm putting together and I plan on getting a align or a beam also, I'd rather go down to the hobby shop and buy blades or parts than waiting a 1/2 month for the brown truck to show up, get my drift.

Status: offline 		I gave my Walkera 36 to someone for free minus the tail which I used on my FP 300 class belt drive custom.

I did get the headspeed up there though it never came flailing apart but yeah I know what you mean. Course I crashed mine to cause the repair bills.

Status: offline 		So I put this thing back together( don't ask why), took it to the field with no training gear and it does fly again, but the pitch servo is all screwed-up(eratic), plus when the blade went flying it did some damage to the align bl430 motor, the poor thing shutters at anything past 1/2 throttle. As I see it, this cheap heli wiped out my $100 dollar plus brushless system in a single flight. It's a good thing that I'm building a mx400, or should I say a mx/t-rex 400-450 heli. I finally got a chance to spool up the mx today, all I can say is it's so much better that the #36 will ever be, the drivetrain sounds and runs smooth, the head is smooth and feels solid when I add a cyclic command to the swash with 0 play or delay. So much better than the 36 will ever be, I should have gone with the mx in the first place and paid less in the end-run, I fly planes that track like their on rails, I give a input and it does it. If anyone thinks the #36 flies great, try flying a t-rex or mx series and see how you feel about the #36. To me the faster and more accurate I get the 36 to react to my imputs the more I feel in control, being a docile flier is the worst way to learn I think, at least with helis. My 36 feels like a pile of poop flying compaired to the reaction time my christen eagle has. I guess all I'm trying to point out to everybody is coaxials and cheap fixed and collective pitch helis are good for newbies who have never flown anything at all, but for well experienced fixed wing pilots, slow and sloppy helis feel out of control all the time. I will admit, the heli thing is new to me, but I'm quickly learning the difference between a cheap heli and a good heli since I bought the mx and put it side by side next to the 36. Christ, I can bend the walkera aluminum parts if I snap a ball link on without using pliers, freakin cheap garbage.
