Default RE: Set up question

Would be a very good idea to have someone experienced help you out with the set up. No two setups are exactly the same, because there will be some small diferences in the birds and personal preferences, but the basic idea is that you set travels fo the servos so you have 0 pitch at mid stick (left stick) and -9 to + 9 degrees at bottom and top position. Might be a good idea to start with lower pitch, maybe 8 degrees? Heli TX's allow you to define "Curves" to alter the responce between stick movement and pitch change, but most folks use a straight line for pitch. For example, if your TX offers 3 point curves you would have a pitch curve of 0, 50%, 100% or if you want to reduce the pitch range temporarily, 10%, 50%, 90%.

For throtle, you use a throtle curve to mix your throtle range to the pitch. What you are trying to achive is idle at low stick, somthing around half throttle or maybe a little less for that bad boy, and you will want a seting close to full at high stick. if you are using 3 point curves, the settings would be somthing like 25%, 40%, 70% it would be a good idea to start a littel low for your throtle settings. what this curve is for is to help keep the head speed constant thruought the pitch range. what you are looking for to start is 1500 or 1600 RPM, when the stick is at 50% or higher. Maybe a little faster 1700-1800 once you get into aerobatics. A good way to get the throtle curve dialed in is to put a board thru the skids and load it down with bricks then fire the beast up and measure the head speed with your airplane Tach. Just prop the tach up against a rock or somthing so it points at the blades. before you do this make sure your throttle is at idle setting! it is a real pain in the ***** to start one up and find you are at full throttle, so be very sure that idle is low stck and that you can shut it down.

Be sure to have a firm grip on the head when you start it up just in case. if you need to shut down, pull the fuel line loose.

Once you have the pitch and throtle set, check your cyclic. if you push forward ont he right stick you should see the disk and heli flex nose down, do the same for back and left and right. you can set your cyclic rates to just about anything, but a low rate that goes maybe 4 or 5 degrees on the paddles would be good to start.

there is lots more, curves for normal and aerobatic flight, tail set up, tuning, a heck of a lot of new stuff to learn. take your time.
