Blade CP pitch change

[desertman]

Here is something that helped me out. Take it for what it is worth. I went down to my local hobby store (Discount Hobby Warehouse) and asked if they could see if my CP was setup right. He (the sales guy) messed around hovering it for a minute and said it needed more pitch. He gave the pitch adjustment links on the head 1 turn each then brought it into a hover. Since then it has behaved much better in a hover.

I am a brand new RC pilot so please be kind with the replies.

For the guys that have been flying for a while please tell me what you think.

Good flying!

well i havent flown long at all but heres what ive found works great..for me anyway :)

make sure both paddles are in line with stab bar, may need to loosen set screw to adjust, also make sure distance from shaft to paddle is same on both as well as total length from shaft to tip of paddle..

im still fine tunning my preffered head speed but right now i run 1 degree pitch at full down stick and 11 at full up, factory set is 0 and 10. and i usually run pitch trim at the midway mark and never hit the iddle up mode as im far far far from 3d flight..lol

I've had to adjust the tail servo gain on the 4 in 1 unit due to the extra torque associated with increased pitch, any changes to pitch, blade set up or head speeds will likely require to adjust gain.. my trusty micro flat head never leaves my pocket..lol

hope this helps and happy hovering :D

I'm a raw beginner too and have to adjust my tracking and pitch. The manual doesn't have any instructions on how to turn the pitch linkage, it looks like you just pop the ball out and turn it as needed and push it back into the ring but I didn't want to break it if I'm wrong. Is that how the hobby shop adjusted it? Is there a tool to pop the ball in and out?

Thanks for your help,

I forgot to mention I have a Blade CP too. The pitch guage didn't come with any instructions, do you know of a web site that tells how to use it properly? Or any web site on Blade CP repairs and adjustments?

Thanks,

Yes, there's a tool to pop the ball links out, the ball link pliers. It took me a while to get mine, had to order them online. If you're just getting into rc helis, or just curious about what else is out there, I highly recommend all the back issues of RC heli mag.

A great site for information on the Blade CP is www.bladecprepair.com. There's more information than you need and the forum is extremely helpful.

Cool little web site Motions. I didn't know it existed. The pitch gauge doesn't come with instructions but is very easy to use.

1. Attach the pitch gauge to the main blade - preferrably close to the head.

2. Align the top of the pitch gauge with the flybar so it is level - eye ball it.

3. Tighten the knob on the pitch gauge to lock in the measurements.

4. Voila! You have the pitch.

Don't feel bad - I had to read up on how to use it as well :D

I picked up a pair of ball pliers but they were too big for the blade CP, the hobby shop said they don't think one is made for micro heli's.

Hellian, where did you order yours from?

I got the tracking clean and the pitch good, now if I can only figure out why it wants to lean to the right as soon as it lifts off. A breeze came up so I tried to set it down quickly and caught a root on one of the skids, that caused the Blade to flip over and it's wanted to lean right all the time ever since. I don't see anything that looks damaged or bent or moved but if I pick up the Blade by the flybar it leans slightly forward and to the right. I can adjust out the forward by adjusting the battery but there is nothing but the trim to adjust side to side ballance.
Being a newby here I don't know if I should start a new thread for the leaning problem, any suggestions?

That's what I thought I had to do but needed the conformation.

When you crash check to see if the spindle is bent (the shaft that the blade grip screw to) or the main shaft (the main gear is attched to) check to see if there is any play between the blade grips(will they pull from one side to the other ) I had to add spacers to mine and check to make sure the washer are installed correctly. (the washers should be flat one side and raised on the other from center hole to half way) Mine were installed backwards. Starting from Blade grip one small washer then the slightly raised washer.(the raised part should always go towards the bearings) This should take some of the slop out of the head assy.
You should unplug both motors (write down orintation of motors as to top plug and bottom plug and which way the red is facing)
Then In idle up mode trim and throttle set to center, then adjust your pitch.
IMOP see what your blade likes first, check the pitch and write it down as a base line.Then make adjustments. Every blade is different depending on who built it and flew it.
