Default very hard takeoff, control crazy

alright, today i have finally been able to get the heli into the air, it has been about 4 weeks since i have got the honey bee cp2 and it has been unliftable lol.. trimmed nice and balanced to a point.. Ok, the the new problem.. When it went into the air and even before, it skids alot of the left, not just a tad bit, but quite a lot and i have no clue on how this is happening or why!!! I want to beable to take off from a standstill or maybe even just have to correct it alittle with the right stick to the right, but when it hits the air, it shoots off left.. I found the old training gear didnt do much for me, so i have fabricated gear using a hanger for baby dresses(the one that is kinda square) and zip tied braces in the middle for the skids to make it wider, yall think it will work alittle better that way, its wider than the training gear and i am hoping for promising results.. Anyone know why its going left so harshly though?

It's simple the CP2 tail rotor is blowing a lot of air to the right to counteract torque. Take a look at where the tail rotor is pointing. The side effect is that the helicopter will want to drift left (newton's 2nd law). Helicopters actually always hover slightly tilted to the right in order to counteract this force. Even full sized helicopters land with 1 skid first.

You can take off from a standstill as you say the trick is to leave the ground with the right skid last (your intentionally tipping it over a little) But this is a hard technique. Most pilots just raise the throttle until it's almost at flight speed and punch it hard until about 1 or 2 ft from the ground then we begin to correct for the force.

When trimming out your helicopter, full sized helicopters have the swash adjusted slightly to the direction they would need to counter. For us it would mean leaving your swash down a few turns to the right this helps center the sticks in a hover.

If you have any other questions don't hesitate to ask the CP2 is nearly identical to the Blade CP which I fly.

Hope this helps,
