thunder tiger titan 50 se

[dubehigh]

just picked this up for kicks

[Jerrymac]

Very nice. Wish I had some extra heli funds "just for kicks" ;D

Is that your first nitro bird? Mine are all electric, and probably will stay that way. Not too sure that I wanna mess with any nitros.

[dubehigh]

no jerry this is my 2nd nitro. i got rid of my trex 700 for this one. its all most done. and so is the gaui. i will be selling my belt cp to finish the gaui.. buy & sell sell to buy. i think i am down to 8 helis from 14.

Well, I think I am up to 5 1/2 helis from none.

I think I am gonna try to sell all the King 2's and parts for them though, and get a Gaui 255.

[dubehigh]

the only reason i had so many is, well i crashed alot, so i would buy another one while i was waiting on parts to fly the one i crashed. it just got out of hand there for awhile. i have a mentor that had the 700 nitro, and he started to build that ttt50se, and he real wanted his 700 back, so we did a trade. he,s happy and i am happy. its all good. he teaches me alot of things.

Welcome, Max!!!! Congrats on the new bird! I know you'll have a blast with it!

[maxmax77]

thanks Scott!

[dunkonu23]

So, Max... how is it going with the new bird?

Scott

[maxmax77]

pretty good Scott 6chs are the best! It's nice to actually know what you guys are talking about on the Struggling thread, lol

, I've got it all figured out except the tail not giving out sufficient power to turn the heli right and the gyro issue we're talking over on RCU; I'm hoping to figure out the gyro today though!

[Jerrymac]

Hey Max, just wondering what your throttle curves are. I don't have a Mini titan, but I do have a Blackhawk 450. I use a cheap telebee gyro on it with a hs-50 tail servo.
With a linear throttle curve in normal mode the head speed is too low at lift-off to give the tail any authority. I use a throttle curve of 0-40-80-90-100 in normal mode. That way I have a high head speed at take off and the tail holds great even with the cheap set-up I am using. I actually use a similar throttle curve on all my helis.

Just a thought.

[maxmax77]

Jerry, that's something I hadn't thought of...unfortunately my radio (JR-xp662) has only three reference points for the throttle curve, which I have set at 0-65-100 (that's what the heli manual suggested)
pitch curve is at 40-75-100

are these right, and will the tail naturally spin out (with the gyro) if I keep it just below takeoff speed for awhile?

thanks

[dunkonu23]

Max, does your radio have different flight modes? I'm talking Normal/idle1/idle2? Reason I'm asking is this. I noticed your pitch settings had something other than 50 in the center position. The collective knowledge on this is that the center position should be 50 if at all possible. If it's not possible, set all your pitch curves identically.. Just sayin'.

Scott

[Jerrymac]

Max, I have to agree with Scott that the pitch curve don't look right.

You should have 0 degrees of blade pitch at center stick. I know some manuals say otherwise, as does my BH450 manual, but, you end up with too much torque from the main blades before the tail has enough rotor speed to hold.

As an example, my Blackhawk 450 manual says to set pitch in normal mode at -3 low stick, +5 center stick, and +10 at high stick. The problem with this is that the heli would get light on the skids below mid-stick, and with not enough head speed the tail would spin out before even lifting the heli off the ground.

I set it to have -3 at low stick, 0 at center stick, and +10 at high stick, in normal mode, and it takes off, and flys great.
In stunt mode you want 0 at center stick and then the same +- at high and low stick. ( Example ) -10, 0, +10.

[maxmax77]

thanks guys, I'll change it. For pitch curve I have normal flight mode, stunt flight mode, and throttle hold mode; they're all now set to 0-50-100. Should that work better now?

-Max

[dunkonu23]

Much, Max! One thing, though... for your normal pitch curve, you may want to bring the low point up to about 40 or so. That way, if you lose it and dump collective, it won't slam into the ground as hard. If you fly mostly in normal mode, do the same thing for your hold curve, for the same reason. Once you get out of flying in normal mode, just make the hold curve 0-50-100 as you have it now.

Scott

[maxmax77]

Scott; awesome! So, will that stop the issue of the tail spinning out wildly as well, since the pitch-to-headspeed ratio is better?

-Max

[dunkonu23]

I don't think so, Max. I'm thinking either your gyro is bad or you need to flip that reversing switch. Can you put up a good closeup picture of the gyro? I'm asking because what doesn't jump out at you might jump out at us over here.

I can tell you, my first helicopter had a rotten gyro on it. I replaced it and never looked back.

Scott

[Jerrymac]

Hey Max, what exactly is the problem with the tail. Kinda hard to follow sometimes over on the "struggling" thread at rcu as there are so many posts over there every day.

One thing I can tell you is that some of the cheaper gyros will "creep" when in HH mode, even sitting on the bench. I ran the cheap telebees on my King 2's and my Blackhawk 450 and they actually held the tail pretty good once they were set up right.

But, they would creep causing the tail to turn all the time. I set them up on the bench by adding some sub-trim till the creep stopped and they worked fine after that. Does your radio have sub-trims?

If so, set the gyro to HH mode, then push the rudder stick to full left or right, then put it back to center very slowly while on the bench. The tail slider should stay at the full left or right position. If it creeps, add sub trim till it stays in the stick position that you gave.

[maxmax77]

Scott; I think the reverse switch is faulty, it doesn't change the servo direction...either way it's flipped, when you rotate the heli in your hand CCW the horn moves towards the tail, not towards the frame. I figured putting the gyro up front would fix that, so that's what I'm going to try next. Here's the pic...should I take one closer up?

Phil; the tail doesn't creep, just at random times the heli will totally spin out. It's never at a certain throttle position, either. I'm confused about the tail-slider position thing. Are you saying that in Headlock mode, when you give full right or left input, then go back to center, the servo will stay at full right/left?
