Align T-REX 600N 700N > My new trex 600N

I just got my Tres 600N the other day and finished yesterday and put MS comp. blades on it wit the stock trex paddles. I rolled wit ali. and ele. and foward ele. stick was like doing a loop when both direction of alieron and back ele. is fine as far as speed. But i cant figure out how to make it loop faster foward, ive went throught and made sure everything was to book and it is, i just cant figure it out, it is the trex 600 sport version, i just put curtis 600mm blades on it and v paddles and 95mm curtis tail blades on it today and it was doing the same thing, plus it says you can get 12 to 14 collective, i can get only 11.5 both ways before it binds wit controls. so what can i do? anyone had this problem. Thanks for the help

check all your link lengths, make sure everything is 90 deg at center stick.

What is your head speed?

Have you measured your cyclic deflection? Your fore/aft is probably less than your aileron. It should flip pretty quickly. I have about +- 7.5 or 8 degrees of cyclic pitch on the main blades for both aileron and elevator

Edit: Also, are you binding with the cyclic stick in the corner at 11.5 degrees of collective? If so, you can probably increase your cyclic atvs a little, because you really shouldn't push the cyclic into the corner at full collective pitch anyway.

Have you checked where the heli balances? If it flips slower on way than the other you are not balanced under the main shaft.

I like to balance my heli with half or third tank of fuel and then plan my flight for the best results. If you have a heli that is not balanced move some stuff around NEVER add any weight to balance it defeats the purpose.

ok, my balence is actully just ever so slightly nose heavy, but it rolls slower foward like i said, everything in is 90 degrees like i said as well, thats what i went through and checked. i am running 1980rpm on head because i have plastic blade grips and dont want ton to break, i ordered metal ones cause they are pretty cheap. At 11.5 neg collective, i am hitting the main shaft bearing bluck, i dont know what that is called, i can think of name at the moment, but i have so it is barley touching in all direction trying to maake in roll quicker. So what else? Thanks for the help

Oh and also my elevater atv is almost bottomed out in my radio, maxed out i mean. my arms are 29mm or what ever across, the arms are the length they need to be, i mean i am ecaxtly to book, thats what i have been ajusting on for past few days, and i relized i had it set up in the stable 3d flight whole on seesaw so i put into nimble 3d just now and now i have less collective, less cyclics, i just dont understand, i set up my trex 450 wit no probs in january. I am kinda disapointed right now. i am going to order the align 3d paddles everyone says i should try, but i dont see how that is gonna help from my v paddles.

i havnet flown it yet but, moveing that arm on the seesaw might help, somthjing it does wit moving the flybar more thern before, is this true, i should go fly it but i would stuill like to know if this arm has been my problem.

Have you measured how much cyclic pitch you have? How are you changing your pitch percentages? You should be using the CCPM mix to adjust how much pitch you get, not using your ATVs. I'm not sure if that's what your doing or not so please ignore if you're not doing this.

If worse comes to worse, I'd suggest you check out Bob Fin-Less's videos on Heli-Freak.com (take out the hyphen) and compare your setup to his. You should easily be able to get tons of pitch on the TRex 600, sport or pro.

well, i dont under stand what you mean, i cant get any more pitch, it is botoming out on top at 11.5 and bottom when i give it the cylics, now i understand that it is rare to use full neg and cyclics but it is still only 11.5 on thos sides top and bottom. the peace that the two pins slides through, it hits the main rotor housing. i am not sure what to do, i have ajusted the linkages on that connect the blades all over to try to get max collective, im just pussled right now, ill look at the vid or what ever it is.

I'm with docjoe, swash menu should be used, not ATV.

Here's the link. Take out the hyphen. It's the CCPM 1 and CCPM 2 videos

If properly setup, you should be able to get 14 degrees of collective pitch.

What's your radio again?

R/CBOONE72.....The linkage instruction on the manual is pretty dead on...When I put mine together, it automatically gave me +16-16..All I have to do is lower it down to +13-13...Do not use ATV's....ATV's are only used if your servos are not in the same speed going up or down. In other words, you sinc the servos travel with ATV's..... On your Swash AFR, the value you are supposed to start is 60 degrees all around. Meaning Aileron, Pitch and Elevator...The only thing I had to adjust in this menu is my pitch to get my pitch setings. ....My elevator and aileron stayed the same since I want my cyclic to be fast at 8 degrees....But before doing all this, make sure that you servos arms are exactly 90 degrees on mid stick. if not, you will not have equal throw on both directions...Just turn that servo arm around until you get 90 degrees. Hope this helps.........

ive noticed today as i was flying that when i have ful negitive collective, when i put my ale/ele stick foward and left or right it hits my main shaft collor, the black collar, it is messing up the inside of my swash plate. but what i think i will do is pop all links from swash and head off, go to book, put back to book specs, then take arms off my servos and center them like the ccpm video says, i dint do it that way, i was in a hurry and forgot to go back and do subtrim part even tho they barley off. And, it seems that this trex is heavier then my rappy 50, is it supposed to be? and on the collective, when i give neg collective then give pos collective it fals some more then goes up. its not snappy, is it because the chopper is to heavy, im using JR 8717 servos. and my radio is 7202 but i hope to get a 12 fgh when it is out. i did start with everything like the book said, all the links and agin still, i bottomed out at 12 degrees but then cyclics bound it up, and if i buy a 440mm flybar and put it on, do you think it will help the roll speed?

ok, i got it all figure3d out, the movie helped me alot, i have 12.5 collective now, i can have 13.5 safley but i want 12.5 for now, and i have 8.5 degrees cyclic, so it flies good now. Part of the problem was my radio setup and the other problem was that the mixing arms were way off and the arms on the servo were off abit as well. so thanks

when seting up your heli, you need to reset all the values on your radio to stock setings.Meaning, NO Subtrims,NO ATV's....If you have value in these, seting up your linkages and servo arms center or 90 degrees would not do you any good.....My swash did not come close to the main shaft colar even when it gave me +16-16......
