Sa342 high tourqe when increasing fuel

[Jackbanan]

Hello i just got the S A342 and am trying to cold start it. I do exactly as i am told in the training mission but when i pull the fuel switch the tourqe just goes to max and starts beeping. then the engine seems to stop after a little while. I am waiting more than 20 seconds after turning on the pump. I also pull the fuel switch to just the point where the rotor starts spinning. I wait for the rotor rpm to match the engine rpm and the verry carefully add fuel little by little but no matter how carefull i am i can never get the fuel beyond a certain point withouth tourqe going to max. I also tried outside of the training mission and the same thing happend

TL;DR:

Can you share a short track or video of your engine start procedure - this will greatly help in diagnosing why you are having an issue(s). Thanks.

Detail:

Common fuel control lever issues are duplicate (axis) control bindings and/or a lack of dead zones at the end/start of the fuel control lever's movement (when bound using an axis).

... sounds like you are starting the rotor spinning with the collective lever "FULLY UP", rather than "FULLY DOWN".

This causes the centrifugal clutch to slip under load (as the rotor and engine RPM aren't in sync) and it will quickly overheat/disintegrate both IRL and in DCS.

So also check you flight control control bindings/settings when starting i.e. using RCTRL+ENTER to display the DCS controls indicator.

Tested using the SA342 Caucasus Cold Start Tutorial in DCS 2.9.18.12899

Test start up in current DCS version and add a list of potential pitfalls that may cause an issue.

This fixed it! i was messing with binds and must have had it upp thank you!
