Tail Rotor

[Jannik]

Hello I build an own helicopter and all works but not the tail rotor. Always my helicopter turn to the left and i dont know why. I changed it so often but it never works. Help me please

Make sure you are using the actual Tail Rotor component. I believe it is the only rotor that can receive a negative collective/blade angle.

I use: Rotor(tail) thats the name of it i mean.

Jannik make sure you have power coming from the engine down the fuselage tail into that rotor if you do verify the block you used if you used them are all facing the right way. Also make sure you have it hooked up to the electric and you have enough power to it in the system to operate all of it.

How are you driving the tail rotor, check the connections, especially enclosed pipes for correct rotation, too easy to have an incorrectly rotated elbow or T. If all else fails upload to the workshop and we can take a look.

Does it turn slowly or does it turn fast?

[Jannik]

It turn fast.

[Jannik]

I looked and i didnt found any wrong connections.

If you upload it to the workshop someone could perhaps take a look at it and tell you what's wrong.

[Jannik]

Yes I would upload it to the workshop .

A few pointers to start with:
1. Use a two bladed rotor (main and tail).
2. Use one or two gearbox(es) to increase rotor rps. Target rotor rps depends on what capabilities you're looking for but should probably be in the range of 45-65. You'll have to test and see what works for you.
3. Make sure main and tail rotor are connected to the same power and spins at the same rps. This means that you'll have to divide the power pipe after the gearbox.
4. Move your main rotor so it sits right above your craft's center of gravity (COG). You can enable a visible COG in the right hand menu. It shows up as a pink transparent cube.
5. Move your tail rotor a bit further back (beware of changes to your COG. Main rotor should always be right above the COG.
6. It drifts to the left because of main rotor torque. You'll have to work your way around this or live with it. It'll still be flyable. You'll have to counter the rotation with small yaw inputs.
7. It would probably be enough to use 1 small engine for this helicopter, or at most 2, depending on what you want it to do.

First thank you so much :) and 2 yes i first build it with a small engine but i cant turn it on so i thought it doesnt work with a small egine but now i know it works also.

I found out that the tail rotor needs 2 gearboxes with the same ratio as the one for the main rotor has to get it working. Don't know why, but it works for my helicopters

[Jannik]

But i dont have a gearbox on the helicopter. Sorry but Im new in this game.

If you use gearboxes with the arrow facing towards the engine you can increase the RPM of the rotors. Try to add a 3x3 gearbox to the tail rotor and set it to 3:! 😉
