which prop makes my heli have foward movment??
 

does the rear prop move my heli foward? it seems to be because i have a 3 channel heli the rear prop moves when i move the right stick foward so since this is a 9101 29 inch double horse people have told me to heat the rear prop and change the pitch to be more agressive, which i did but i dont really see the heli going any faster foward?? should i change the pitch so the blades are flat? but mainly i am asking which prop moves a 3 channel heli foward, details please and which way do i change the pitch on the rear prop( if thats the prop thats moves it foward) thanks all

If it's a co-axial heli, i.e. one with two main rotors on a single shaft, and if the rear rotor is facing upward (as opposed to sideways as on most real helicopters).. Then 'yes' the rear rotor is the one that makes the heli go forward and backward.

this is my heli is this sideways or upward? will the rear prop in this pic make it go foward or is it the main blades.

The rear rotor/prop is pointing upward so yes, it will lift and lower the tail and cause the model to move forward or back.

ok thanks, now my next Qs is this, i heated the rear blades with a pencil torch and gave the blades more pitch but didnt notice a differance, which way should i pitch the blades so it goes faster foward, cause from the factory it moves very slow if any movement at all. thanks again, details please

You may be better off finding a similar rotor with a larger area (larger diameter) instead of changing the pitch. Changing the pitch may help, but a larger diameter would probably more effective.

ok guys i tried all sorts of pitch with no result, how about if i turn the rear bade to be under the bar rather than on top, will that make a differance, another words reverse the blade assembly, i will have to reverse the pitch of the blades but do you think it will fly faster under the bar rather than on top? thanks

Coax helis are very stable, by nature, because of the big flybar.
This flybar tends to bring the heli back to a level attitude.
Your helicopter isn't meant to fly real fast, and the only way you
will likely get it to do so is to increase the speed of the tail motor, or
to increase the pitch but if you try to bend the prop, you have to make
both sides the same and that is difficult.

Also, is your heli gyro stabilized? If so, that may counteract the forward motion. I could be wrong, though. I've been known to be...

The gyro only works in yaw, so wont have any effect on forward motion.. The comments about these co-axial helis being very stable is spot on.. They are designed to be stable and easy to fly (even i can fly one!). If you want fast and manoeuvrable then you probably need to move to a more advances single rotor type. Moving the tail rotor top the bottom wont increase performance at all but will make the rotor easier to damage.

i dont want to fly fast but most of the time it just hovers in one spot and i have to lower or raise it to even move a little bit (very slow) i just want to make it do more than hover i have a double horse micro heli that is also co-axial and it goes very fast foward, why doesnt my big one do that, it is all the same phisics as mymicro? just asking and thanks for al the help

Try unplugging the main motors and then plug in the battery.,
Now the only motor that should work would be the tail motor.

When you move the stick forward and backward, does the tail
motor speed up (forward) and slow down (backward) ?

You would probably need to have the throttle stick up some to get
the tail motor to actually turn at all. If the motor isn't turning
much, then maybe you have a bad tail motor.

great info thanks i wil try it but guess what i did!? now this might sound crazy but being that the radio isnt high tech. and that i am limited to trimming the foward movement i dremaled the casing on the top were the right stick stops to buy more real estate in the foward movement and it worked! i now have better foward speed (not fast) but it moves alot better, after all this is only a 80 dollor 29 inch rtf heli. i wouldnt do this to my align helis radio.

ok, the top rotor has a mecanical gyro, not a flybar. it is what gives it stability, the faster you move forward the more it will fight backward.
and since you are pitching the heli with the tail it will counter act against that as well.
spin the blades up and tilt it, you will see the weight move out of plane(horizontal as in a hover).
the electronic gyro balances the rotor to each other to keep it straight. if you twich it in yaw you will here one motor try to speed up to counter this.

MORE over , need to move to a single rotor for more speed. a blade msr or sr 120 has the cobo of a flybar/mech gyro on the main blade for good stabilite but will move faster.. but it still fights it i forward flight.

These type of helis rarely move forward very fast. Stick a small (marble size) lump of bluetack or plasticine in the canopy nose and that will aid your forward flight speed.
