im having problems with my new cb100..the rudder, throttle, ailerons are fine..but when i push forward-backward (elevator) it doesnt quite go forward and backward..its very slow and looks like its taking the heli too much for it to go ..what could the problem be?

Obvious I know but check for binding. Take the horn off the servo and see if the servo giving full throw. Perhaps you changed a radio setting inadvertently. Possible Walkera Gremlins.

well a friend of mine just said to me if i dont use throttle use with the evelator and ailerons it wont move the heli..i mean the problem i told him about was (if i hover and move the stick forward backward it wont move..will only move slowly) could this be becaues im not using the throttle?

well, if you tilt forwards (or any other direction) enough and give it no added throttle/collective, you'll go into the ground, but you won't do it slowly.

When the heli is stationary and engine turned off, how does the swashplate respond to your cyclic commands? is it binding on anything? is it getting full travel?

check your travel limits in your transmitter. What Tx are you using? Ideally, you should set your travel limits in the transmitter as close to 100% as you can without any mechanical binding. Also, check your dual-rate settings and switches. it is possible you accidentally switched elevator to a lower rate (same effect as travel limits) and so you are not getting full length of travel.

everything seems to be good except when i check the swashplate movement and the aileron is perfect..and the elevator is a bit not too perfect..how do i change this. and the servos are perfect..a friend of mine tried to switch it to see..he worked on the swashplate because it wasnt moving when moving the stick on the radio..its not perfect though..what should i do?

you should start by telling us what radio you are using.

you should also check mechanical travel. Take the linkage rod off the elevator servo wheel and operate it by hand. can you get full travel that way? Is it relatively free of resistance? If you can get fully travel, and the travel is smooth and easy, the problem is with the servo, that particular receiver channel, or your radio setup. if the travel is stiff or you cant get full movement out of it, problem is mechanical.

Hi shurugal im using wk 2402 tx..and i think i know the problem..after i take the linkage off the servo..move the servo hand a bit down and lock it in place and re-attach the linkage to the servo??? will this work ..because a friend came yesterday and moved the servo hand a bit down because it wasnt getting full mechanical travel..should i try this.. or should i take it to my buddy again and he can fix it for me and i can also ask him to show me how to fix it..let me know soon
