Default RE: CPP trim and weights

Hi swixtt, I used the the forums to pick up on tips and trimming advice, a properly trimmed heli makes all the difference when hovering. Also last month when I started I was wondering how I'm going to get this thing off the ground, how do I set it up and how do I fix it, all these questions were answered by reading threads on this forum and from hands on rebuilding and setting up the heli after every mishap. Now I know the heli like the back of my hand, can fix and setup the heli really good so when I go to fly there is no vibrations and hovering is easier. The biggest things I look for when setting it up are the mainshaft/gear is straight, spindle straight, swashplate level, blades balanced, blades tracked, flybar straight, check the CG of heli from the flybar and adjust your proportional and gain pots. If all these things check out then you will have a vibration free heli that will seem more stable when hovering. When I track the blades I use a different color grease paint on the tip of each blade(the kind you use for kids face painting), put weights on the landing gear to hold down the heli, spin it up to 3/4 throttle then using a folded sheet of paper carefully while holding it level and flush to the surface of the table slide it towards the spinning blades until they nick the paper. If the two colors are different in height you need to turn the pitch link of the low blade a half a turn at a time until they both nick the paper at the same height. If your pitch is off you might need to lower the top blade but so far I've only needed to raise the lower blade. I know it sounds like alot to do but it should be done after any repairs to the heli and now after a few times I can completely rebuild my heli in the time it takes to charge a battery. There are also a few mods I have done from reading this forum, extra weights on flybar, sym plasti-blades, super skids, fuse mod, paper clip mod and I put a piece of fuel line tube on the throttle tab inside the TX to stop the ratchetting effect. I do have a DD tail upgrade on order. Hope this helps, Good Luck and Happy Flying. Rick
