Mixing level setup?
Any tips on the head setup? Are you setting up the mixing levels per drawing in instructions? I fly pretty aggressive. At least until I hit the ground.

if you want fast and snappy, put the balls on the mixing arm thats on the blade grip (both closer to the center where it attaches to the blade grip) and on the flybar, put the link on the one closest to the headblock

oh, and dont hit the ground, lol...

ground = BAD!!!

Thanks. What type of cyclic pitch are you running? I like the way build is going. I can't wait to see how she fly's!!

if i remember correctly, im running about 8 or 9 degrees. i would also suggest that you replace the stock dampers with the red 80 durometer dampers from the raptor 50, really seems to smooth the heli out a bit as the tock ones are almost like hard plastic.

Note on the Dampeners. I had a lot of binding and switched to the raptor dampeners. The raptor dampeners did great. I crashed due to the tail exploding and got a new rotor hub because it was bent from the crash. The newer hub has a larger diameter hole inside the head (toward the head button) allowing the stock dampeners to compress a little further when you tighten the blade grips and the flap collars push against the dampeners. The head now works the way I expected it to with the new main rotor hub and stock dampeners.

As far as swash mixes and collective, I am dying to see the bell crank kit. I'm hoping it will allow for smaller servo horns, thereby allowing for higher resolution mixing. I have mine set to around 42% in the swash mix right now for Ail and Ele. I'd like to see at least 60-75 to regain some of the resolution of the servos. A cyclock would do this well, but I want to go flybarless on this machine by the end of the year. So the cyclock would go back in the toolbox after a few months.

I have some of the 80 durometer dampers laying around.
The head actually gets to stiff. The xtreme dampers I use for my aligns are almost like plastic too. Very hard. I'll have to compare them.
Does the bellcrank kit relocate the servo's so you can change the ratio of the servo movement by having a bellcrank between the servo horn and the head?

exactly, with the bell crank setup, the servos are all mounted in the frame, but from my understanding is that it will still be the same ratio 1:1 that translates from the servo to the head. alex is right though, you will be able to change to location to get a higher resolution, but your gonna sacrafice a little bit of speed by doing so.

Jeez..... You weren't kidding when you said the dampers are like a piece of plastic.

If you decide to use the stock dampers, you will most likely need to coat them in silicone, then coat the spindle in silicone. I used a drill to insert the spindle through the dampers. Be careful with the drill speed. Just bump the trigger or the dampers will start to melt.

I didn't have any trouble with the stock dampers, just made sure that the dampers and feathering spindle were well coated in silicon grease before assembling. Went together fine with no binding. You will not get them fully seated without some lubrication (that sounds wrong but you know what I mean).

Think I'm running +/- 10 on mine pitch wise. Seems to go well, but still running motor in.

Cheers,

Simon

I ended up setting the dampers in hot water. Then installing them. The spindle went in nice after that. I wanted to see how it fly's with the stock dampers. My thinking is the stiffer the better. But we will see.

while true, this can also cause unwanted vibrations (was the issue with both my competitions). switching to the r50 red dampers took care of that problem

True.. I've had bad vibrations at slower speeds with the the hard xtreme dampers. But usually smooths out at higher rpms.
You still had issues when in idle up?

yep, with a hs of 2000, there was still some vibrations, but as soon as i swapped out the dampers to the r50 red ones, smoothed right out

Not had any problems with mine. I always make sure there is grease on the feathering shaft etc. No fuel foaming, slight buzz on the vertical tail fin, but I think this is due to the motor still running on the rich side.

Cheers,

Simon
