Yea Shane, I would really reccommend you getting with another experienced nitro guy. I know you say this is your 7th heli, but you make me nervous (that you might hurt your equipment or yourself) with all these tuning/starting problems and not knowing how to adjust throttle curves to achieve a consistent head speed. I'd be more than willing to talk ta ya over the phone, but you really need someone to give you hands on experience.

There is a throttle and pitch curve setup in your radio. In my optic 6, he default throttle for normal mode was 0-25-50-75-100. Idle 1 and 2 defaults were 100-75-50-75-100. Essentially what you first want to do is set up your pitch curves in normal for -2 at the bottom, 0 in the middle, and 8 at the top. In idle one i would set it at -10 bottom, 0 middle, and +10 at top. I would do the same for idle one as idle 2. For pitch settings, all radios are different. My radio took 0 as full negative with 100 be full posotive. Ensure that the percentages you imput at each point allow for smooth transition throughout the collective range and that you have the pitch values i suggested at each stick point. Now for the throttle curves. Usually, 0 represents idle and 100 represents full throttle. In normal mode, usually you are targeting a lower headspeed. I don't have experience with a 90 so i am not sure what hs you should be running. Find other throttle curves on the internet for .90 helis wich will get you in the ballpark of what HS you should be running.

No trust me this helicopter was setup by pros or people that knew alot more then me. If not I wouldn't be flying it or trying to. It was setup by local hobby shop owner and his and my new flying buds. I wouldn't have tryed flying if I hadn't had help setting it up. I just flew my first tank threw today or full tank well almost full don't like to fill to top most of time. But it flew great still think head speed is probably high but so was my other one for like aa year because I don't have a tac. But this is my first belt drive tail heli and the tail belt got los today. It was tight before flight but as I flew seemed tail trim was getting off and tail wagged some what could tell if I was doing the wagging or not. Then I landed after it ran out well before and heard something but I think I hear stuff sometimes lol. So I flew more and tail got worse long story short tail belt was getting lose. I hear thats normal thats only thing that was going wrong. Also boy it is responsive with the Radix blades my first Radix blades and like then maybe to touch lol. But also it was running way rich didn't care needs that to break it in. But sure goes through fuel lol compared to my 30 but still love it.

If it is cold out when you fly it is normal for the belt to become loose.
With the temperature difference between your house where you set the heli up and out doors in the cold the aluminum tail boom can shrink by 1/8 (.125) inch.
This is just something that happens to ALL helies with a belt drive and aluminum boom.
The bigger the heli the more noticeable it is.
That is why all of my helies have a BOOM mounted tail servo. this way I can adjust the belt tension with out messing with the rudder trim.

Ok well I have flown it I think like 2-3 tanks threw it lost track when I took out half a tank because it had grass in it maybe. But I love the way it fly's. I love the power I love the feel and stability it has. I just hate how fast it eats fuel lol compared to my 30 but I expected that just not this much lol. I can't even do but a few circles around me before at least half a tank is gone if not more. Flying time seems like not much at all maybe like 10mins or seems that. On my 30 I fly tell I was ready to take it in most of time on one tank. Tank on this thing is huge to and I have flown probably have a gallon or close in it. Oh also I have video's of me flying it now. Video's quality suck because of the cam used sorry. But you can see them at http://youtube.com/shanee86 . I flew the heck out of it one time but no one was around to record it. I almost crashed it because it died in the air and then turned noise in and I don't like to fly noise in or can't or won't. But I got it down good check out the vids if you want thanks.

Well no I can say this heli has its first wounds or maybe its first crash. Not really a crash but I broke some parts. I was out flying hovering it fine then I started yanking the throttle up and down up and down a bunch and then was in a hover. Then it started spinning like tail broke oh no. So I brought it down and found out the tail or one tail blade was broke off opps and the tail support beems were on one side a screw broke. I have had only trouble so far with this helis tail being it my first belt drive tail and belt keeps losing up etc. But it scared me more then anything really I have had helis tail start spining before and landed fine. But those were small electric. So I guess I did my first Piro with this heli lol. But now I am going to buy some Radix tail blades and put a new screw in hope that is all it needs. I smelled something burning or think I did hope thats not broke maybe it was the belt not sure. Here's some photos:

Be sure and pay close attention to the tail shaft and bearings. My Stinger 90 pitched a tail blade about a year ago and got the shaft and bearings also. Last week my 50 broke a tail hub. I autoed it down but the vibration killed everything from the frame back.

It is obvious.
On Xmas eve you should be opening presents, not flying.
You obviously did not get enough presents to keep you busy.
You'll have to have a talk with Santa about that.

Lol we opened presents today or Christmas Day but yea I was off both days so flew Christmas Eve. But I am not sure what happened but it happened and now I need parts. But I flew it a few times just fine before something happened and the tail started spinning on me. I was having problems with the belt though getting lose. I am not sure why it started spinning maybe the belt but don't think so just know tail spoon and I brought it down kind of hard because I freaked when it started spinning and landed it. But maybe I made is spin or it was intereference or maybe the tail blade broke in the air not sure. To me it looks like I hit the tail and broke the tail blade and bent the shaft at same time. But that doesn't explain why it started spinning so I am thinking it might have broke in air then I hit and broke rest not sure.

Sorry for your bad luck . There is nothing wrong with a belt as long as you keep an eye on them . Your 90 sounds alot like the Gohbee90 i had and it was`nt good . The tail blade that is missing where did you find it ? If it was right there with the heli then it did`nt come off in the air and make the heli start to spin . I would look for something else.

I am not sure were it came off when it was on the ground it wasn't on the ground by it or I didn't see it. I looked some but not that hard and didn't see it but even if it came off on the ground it would have been spinning and could have went far off. But I am not sure what happened. Right now I am trying to figure out what parts I need. I am trying to figure out what tail shaft I need I see 2 on the gohbee site. This one http://www.gohbee.com/Merchant2/mer...egory_Code=1450 and this one http://www.gohbee.com/Merchant2/mer...egory_Code=1450 the one I broke or bent is the one the tail blades go around or go threw the tail blade holder on and around the tail belt pulley on the back of tail. Any idea's witch one it is anyone? If I have alot of problems I will get Raptor and put all my parts such as servos etc on it and sell this one or keep for parts. But as for this tail blade break or whatever I think I may have broke it not being carefully caring it threw the house etc so it may have been crack already from a bumb in the house etc.

Yea I looked at the manual and not sure still. I haven't took mine all the way apart yea not sure exactly the best way still thinking on it. But also I now notice I need a new strut to dang it. I know why I brought it in to hard when it started spinning I brought it down hard to hard looks like also a plastic piece around fuel tank is gone like a button thing no big deal. I am now wondering if something with main gear didn't slip or something main gear has some black on it but not worn not sure. I am so unhappy about this now keep finding more. I can fly helis good and was doing good not sure what happened only secound time crashing a nitro heli in years.
Also I will admit the guys at local hobby shop told me to take it easy on my new bird. Well I wasn't I guess but still I wasn't doing anything it shouldn't have been able to handle if it can't then I want something else. What was I doing well I was playing with the throttle alot because I loved the power it has meaning I was playing like I was on G3 jerking throttle up and down making it climb and fall fast up and down over and over but not that bad. I mean I was going up and down a few feet punshing gas and letting it fall and then again. But when this happened I was in a hover about to do some more and it started spinning. I am not sure what happened but I know it could have been worse that is only thing I am thinking. I heard that is the way to test your tuning and so I was but I did to the extreme maybe because I did if fast sometimes. But it should be able to handle that wasn't even close to what I seen some do with there Trex 600 lol. I also can't say I won't play with throttle again once I fix it I am sure I will and did this the days before to and no problems just died once because wasn't tuned right that was what I was testing to.

Shanee, if you have a bent shaft you can use a dremel cutoff wheel to get it off
