I got my Al swash from Horizon today! But NOT the Bell/Hiller, It's on backorder.

It's dark when I get home from work so I only have about 5 mins. of flight. The disc looks like a still Picture, no floating around any more.

I set Zero pitch and I was getting sudden dropping. I have about 3/4 inch of play at the blade tips when I hold the main gear and move the tips. Going to replace the center hub and set in a little pitch. That will be on Saturday in the daylight.

I've had a blade cp since the end of August. AEK kit, DD mod, and six sets of blades and three booms. Been having the sudden drop syndrome for about two months.

Last night when I installed the new metal swash from Horizon the disc looked fantastic, Rock steady. But, the dropping was much worse. Went to work on removing the play in the head. New center hub, and fly bar links to the swash. this helped some.

The main thing was the pitch. I have used the 'Align' micro gauge to set it at zero with the throttle and trim all the down. The trouble is this gauge has most of its weight aft of the blade, this pre-loads the play to the positive side of pitch. If I lift the gauge to pre-load the blade play to negative side there is two degrees negative. This means when in the air any movement of the sticks can cause sudden negative pitch from the play, and a sudden dorp.

Well, I put in one degree of positive when the play is pre-loaded to the negative. What a Differance! It's a whole new bird. Easy to fly, and hover. Did a full battery in the rec room tonight, NO DROPPING. I could keep her six inches off the rug in one place as long as I wanted.

Now I can't wait for my new 'Spectrum' to come so I can loose the interference.

I don't have a pitch gauge but I totally agree with you. I've been flying my Blade CP since July. I've done a lot of tinkering and rebuilding. I've had my pitch range from way to high to way too low. High head speed is great for many things but you can get too much with this little heli. If you encounter the sudden drop syndrome, increase your pitch a little. Seems to take care of it every time.
The Blade CP is really my only heli. I'm wondering: Do most RC helis have this much slop in their rotor heads?!

I would be hovering at three or four feet and make a correction for whatever, nose left or right, drift any direction. And, WAM, uncontroled sudden drop into blacktop. Mostly when moving nose right or moving right. The result was damage to boom or blades. Thats why I went back to wood blades from the carbons, woodies don't chop the boom in half.

This is mostly my fault, You have to be careful when setting blade tracking when You replace blades. That 's why I got the pitch gauge. Can You tell this is my first heli?

When installing the new blades and getting ready for flight, are you supposed to leave slack in the blades so that you can move them easily with your fingers or are they supposed to be tightened down hard? I leave them tightened down.

I also had a problem with sudden drops, it was obviously my blades from smacking into things. Once I put the new blades on I had no problem with lift or dropping. One crack of the wooden blade and its pretty much no lift off. Thats why I am thinking of trying out the carbon fiber blades to see what happens. They are about $39 from my local hobby shop. Does anybody not recommend them? Or should I go with a different blade?

I don't know if much of your are familiar with this site, however they offer great upgrades for the Blade CP (this is what I ATTEMPT to fly). I am thinking about purchasing the complete CNC head unit. Check it out: http://www.helihobby.com/html/blade_helicopter.html

For the price I think its a great thing to upgrade. I was also thinking about changing the base and upgrading the a twin tail motor setup.

If you decide to upgrade your tail go to the URL below. This is the upgrade most are raving about.

The main blades should be tightened until the blades do not move if you hold the Heli on its side. The should move slightly if you give the Heli a little shake. If they are too loose you risk boom strikes. If too tight you will have vibration and poor flying as they cannot sling out to their correct lead/lag positions.

Thanks for the tip! I will try it once my battery is charged up. At my local hobby shop on Thursdays from 6-8pm they have free heli lessons. Next week I will go to see what its all about. I was told by one of the employees that its well worth going because they will help me with the basics and check to make sure my heli is adjusted correctly.

Got my new swash and lg upgrade yesterday. The lg upgrade was not ready for the bcp but it worked. I hear they have a BCP specific kit, holes predrilled for attaching to the BCP frame. I had to drill mine and the fit was really tight.

The throw on the new swash arms is actually about 2mm wider e.g. the arms on the swash are actually 1.5 mm longer than the stock ones. This means that it will actually slow cyclic down if you simply mount the new swash on and snap on the ball links.

Fly's good though.
