    ok so im thinking ill be able to get out n go flying this weekend
    so im looken arround for some spare parts (i know ill crash so better save on down time by pre ordering)

    now for the stupid question lol
    the stock blades for this heli are main blade :315 mm
    or i can go Carbon Fiber Main Blade for electric 450 helicopter(335mm)

    so wats the difference tween 20 mm?
    dose size matter (lol)

    and stupid question number 2
    i spooled the heli up and it seems i have a small kink in my flybar, i bent it back by hand ( so now its only slightly kinky lol) will this mean im grounded till i can get a new one, or is close enough good enough?

    Hey man, I have a belt cp also :)

    OK.. so question number one. The 20mm longer blades will work fine. You might need to stay with the shorter ones if you were going to do crazy 3D stuff, just to keep up the rpms, but I'm assuming thats not what you're doing.. The real issue that you have to watch out for with the belt cp is, the stock blades (the part that goes into the blade grips) are *thicker* than the normal 450 replacement ones... So when you go to install the 450 blades, you will have a little slop, or space in between the blade grip and the blade itself. BUT, you can remedy that by going to your local hardware store and getting a couple washers that will fill the gap, and put them in with the new blades... It will work fine.

    Question two. This is where opinions sometimes differ... Most heli guys that I talk to say replace it if its even SLIGHTLY bend or damaged... And that goes for every part on the heli... But, I have gotten away with straightening a flybar by hand on many occasions. You just have to get it REALLY close. and after you straighten it, you have to make sure your paddles are flat and level when your blades are at 0 degrees pitch. If you haven't already, buy a pitch gauge. You will need it after every wreck.

    Here is the site that I get my parts from: New Belt CP X Thats the belt cpx page. Good luck!

    P.S. Question number 1.5.... Of course it matters. ;)

    I agree with the Beast. As a heli guy I'm one of the ones that say replace but you'll be fine with a heli this size. You wanna keep an eye on excess vibrations and make sure your blades are tracking perfectly. Like Beast said you'll need a pitch gauge, I would also recommend a small ruler or the micro measuring tools (brain fart, can't remember the name) so you can measure the distance of your flybar paddles to the shaft, they should be exactly the same.. You will get really good at doing all this fine work after a few crashes, we've all been in your shoes so we will always be here when you need help.

    Enjoy

    got me a pitch gauge and some new blades today
    and when i was there i saw flybar weights (this aparently makes the heli more stable and easyer to handle, says the shop assistant)
    had a lil look round and so far have found 0 proof of it

    you guys ever hear of flybar wieghts to make the heli more stable?
    or did i just donate another $10 to the im a dumbass fund?

    Actually he wasn't lying. Flybar weighs were an old school way of toning down your controls to make the heli react slower, giving the illusion of more stability. It was a training method used for generations, nowadays with computerized radios we can imitate the same thing by slowing servo throws, expo and so on.. Weights will still help regardless but digital radios sorta illuminated the need unless you don't have one. so it's still $10 well spent.
