I am tracking blades on one of my helis getting ready to hover,and I found that as I spool up,that at around half stick or so both blades don't fly even until positive pitch starts then the blades fly together perfectly tracked and the the thrust is smooth,as the heli starts to pull up

So are blades supposed to be perfectly in unison at full or above mid stick or are they supposed to be tracked through the entire range???

On my 450, I hold it and do it at mid stick. Is it the right way, probably not. On my 500 and 600, I will check them while hovering eye level. Since I have gone fybarless and use a digital pitch gauge, I haven't had to to redo the pitch at all.

Hello rcpilot1982, I am not sure of your experience level but this video should answer all your questions about tracking and vibrations on spool up. I'v been flying 3 years and I watched it a few months back to keep up on my basics. If you watch these 13 minutes, it will save you HOURS of headache.Tape works well in the beginning, after you've done it over 100 times, you won't need it anymore.

Watch at YouTube

On my 450, I hold it and do it at mid stick.
Haha, same way I did it and I was taught by my instructor who also did that, and liked to drink / fly his helis.

I didnt look at the video but this is my opinion

If ever thing on your Heli is tight like links, servos, blade grip bearings, swash your blades should track perfect at zero pitch. It's not always tracking true with pitch applied and its hard to tell sometimes.

Yeah what I do is wrap a towel around my neck,and put on a pair of safety goggles,and hold the heli in my left hand Znd spool her up....the 500 scares me thoug while doing this....

Yeah right.....the 500 that was funny huh? I do like my head where it is.

I learned full ccpm setup last summer after coming back from a defeat in 2005 when I had an ergo 60, a JR E voager,and all, my GMP cobras and king cobras.

I was young and the lead guitarist of a heavy metal band...still am,but all the lingo intimidated me like pitch curves and throttle curves and expo,and dual rates'and centering the servos at mid stick.

I had no way of knowing if I was correct,so after crashing my GMP cobra 50,and not being able to get my Ergo 60 off the ground or my JR E voyeger....(god I loved those helies) and after trying a ready to fly Eflight blade cp,and not being able to hover it,as it was wildly of control...ready to fly.....lol...I gave up and sold my e voyeger and ergo 60 but kept all my crickets and king cobras and cobra 50s

God I wish I knew then what I know now,I would still have the Ergo 60 and Voyeger e especially

Now I'm ready to install my cobra 50 in my original GMP jet ranger fusalage.

I just have a few more questions regarding the ccpm setup,as in how to get al three servos exactly the same at 90...I do pretty good with my verneas measring from the top of the main gear to the control ball but I want even more accuracy since main gears are usualy warped.

Also how to know when your swash is in the exact middle of travel when you have a flybarless heli with no lower mixing arms.

With my Beam e4 advance fbl,I have a set of mixing arms on the bottom,so when they are at 90 is when I know,if that's the correct way? But my mini titan does not have them

By the way is the new mini titan v2 fbl a DFC head?? All I have is control rods coming from the swash to the head

if I ever track blades the helis on the groud and I have a good distance between heli and I and my butt in the air.

don't know any good way to get them dead on perfect but I would think your not far off doing them your way for 90 degrees. if you want to use the main gear mark a spot on it with a marker and measure from that spot on both sides so you make up for wobbly gears.

for swash level i'v always tried to use the measurements that the company gives for the link rods, and then see if you blades grips are centered and just go from there and adjust to zero pitch.

just look at the picture of the titan and no its not dfc but its doesn't look far off. the good thing about that setup it still can pivot at blade grip and swash.

hope this helps a little.

I have found that if I take an extra min or so and get the blades EXACTLY at 0 pitch mid stick on the bench,the blades track perfectly,at the most one blade may need a half turn.

In my opinion tracking the heli with blades spinning on the bench or in your hand is a waste of time as neither are real world conditions.

As said, I set the blades to 0,then hover,if it needs an adjustment,land and adjust.Once set its good to go unless me or the ground makes a change.

Its not complicated,dont over think it.0 pitch at mid,hover and check,adjust if needed, go fly.If it takes more than 5-10 min,you're doing something wrong

Yes you know I actually am able to it by making sure both blades are exactly zero pitch at mid stick.

With my expensive helies that have no slop anywhere,like my Beam E4 Advance FBL,Mini Titan FBL,Miniature Aircraft Furion 450,but the cheaper ones like my erazor???? I mean

Yeam come to think of it,my blades do track perfectly at all stick levels on those big money birds,but the erazor has a lot of slop in the center swash hub so it tracks perfectly at above mid stick and so on.

I do the same as Fenderstat,set both blades at 0 degrees half stick,i cant see how the tracking can be out if both are at 0 degrees,in the video he has adjusted one of the links,so that means one blade will be not at 0 degrees half stick and how do you know which blade to check every time you might want to change pitch setting,marking it i guess

blades have alot to do with tracking. not every blade is perfect. if one is warped itll track bad. ive had bad blades before. just get them close and fly. if ur heli is properly setup and u need more then a turn or two to track blades may be to blame

all bets are off if theres a lot of slop.If you dont have that precision and consistency,being able to get 0 deg every time,you'll never have solid tracking.On a small heli a small bit of movement can translate to 1-2 deg of pitch and thats a LOT when it comes to tracking.

if each blade can be +/-2 deg.One side could be -1 and the other +2.that will drive you nuts trying to set

As you follow the procedural posts on blade tracking, do not entertain the idea or engage in clamping the skids or the heli in a vice. This behavior has the potential for being dangerous.

If your heli mechanics and Tx are set-up correctly, your heli will not ascend at mid-stick.

Good luck.

Yes the heli starts to lift after mid stick once positive pitch starts in.
