I CANT GET THE PITCH RIGHT. TRIED FOR HOURS BUT IT IS GETTING FUSTRATING. I CAN GET ONE BLADE RIGHT BUT NOT THE OTHER. SOMEONE HELP. thank you.

[Mike_117]

mark one blade grip to adjust. and leave the other alone.. you'll be going back and forth all day trying to adjust both.

if you have another set of blades.. throw them on . might have a warped blade if you can never get them to track.

Havent measured (I should) but my blades track perfect. While on throttle hold and I raise and lower the throttle I do notice one blade reacts more than the other. It flies fine so I am not messing with it. See how it flies and go from there....

[stevenlogin]

K. ill take your advice

[LockMD]

Just take it SLOW.......and remember where throttle hold is, its your friend.

[stevenlogin]

this is a very noobie question but wat does bog and warp mean?

[LockMD]

use it in a sentence....LOL

bog is your motor is bogged down from too much pitch (I think) warp ???

oh someone said your blade could be warped (twisted) not true...

I know you've mentioned that you don't use any subtrim and that's why most people do.
Leveling the servo arms at half stick increases the chances that the servo movement, on all three cyclic servos, is the same for a given stick input.

It's also the reason for leveling the swashplate at high and low stick by using end point adjustment or Travel Adjust on the DX6i.

Making sure that the servo arms are level at center (sub trim) and then adjusting the swash to be level throughout the full collective movement (travel adjust) ensures that cyclic response and pitch are as consistant as possible.

This is all per Finless Bob in the CCPM videos.

Building up from a solid foundation is the key to a spot on setup.

VERY GOOD ADVICE!

Thank you.....even though my subs are zero, my blades are not true - fine for normal but would prob be disaster if I tried to flip in this condition.

ye. i've seen that video and most others but he uses an align heli and it is kinda different from the b400 so some parts i cant exactly understand what to do.

steven,

Watch the videos posted by sokal they are very good and B400 specific.
I don't remember if he covered using end points to level the swash at high and low stick positions.

Here's the short of it, I used to do this by eye but now I use a swashplate leveling tool:
1. Use Subtrim to level all cyclic servo arms at half stick. You want them to be at 90d to the linkage attached to them. Once these are set you don't touch them again.
2. Level the swashplate at half stick. To do this adjust the length of the push rods.
3. Check that the swashplate is level at full (high) stick. If it is off use Travel Adjust to increase or decrease the servo(s) throw that is off.
4. Check that the swash is level at low stick. If it is off, again use Travel Adjust on the appropriate channel(s).

After doing so, your swash is as level as it's going to get throughout the collective range.
Now you can proceed with checking and adjusting pitch at the various stick positions.

This all assumes that your swash is in the correct position so that it will not bind at the high and low stick positions. But that's a different thread and way too long for me to peck out with two fingers.

Hope this helps.
