Im flying with throttle curves? How do yours look like??

 

I use a govenor on the vbar, works great. The revs are all over the place without a gov on a nitro. Also, especially when tuning a motor, after the first 20 or 30 flights, change all the fuel lines. They can develop very small holes which will lean your engine out. If your motor is pumped (nipple on the back plate) then it should be all good. It just looks on the pic of your heli it looks like you have the back pressure from the pipe, not the engine, my mistake. When you open the fuel line do you have a big hiss of air coming out of the line (ie tank de-pressurizing)?

A govenor and good collective management will help with the bogging. Collective management is using just enough collective to do the move, if you use too much collective, your heli will bog, electrics have enough power not to worried too much with a big hand full of collective

Yeah I have to let out the pressure after every flight like pfffffffff LOL. I will consider a governor..

 

That sounds right - do it soon as you land or you can compression lock your motor with fuel

This is how I expect my Nitro to perform, but it isnt even close to that... :/

 

Today we had 19 degrees here in Switzerland and pretty windy conditions. The Performance of the 600N is waaaay better with this temperatures. Now ist fun to fly. I got 10 liters through now.

 

What was that paid amount in americanos?

On the matter of a header tank, basically the tank bob in the main tank will not have fuel going to it when the tank is emptying, sloshing and aerating the fuel when the heli is doing all sorts of stuff, the fuel line will take on air bubbles and result in a lean condition. The header tank always stays full as it removes fuel from the main tank and the fuel in it does not get filled with air. There's much less air in the smaller header tank than in the main tank and the header should stay full even up to the last drop of main tank fuel when the tank bob is looking for a few last droplets of nitro mix. The header tank is also a good way to avoid running out a main tank and having nothing in reserve to fly to your take off zone. The header tank is a must have.

Your heli started out rich but as you began to stunt it the fuel got some air thereby leaning the motor out more, get the header tank on there asap as the pumps can only pump fuel that is at the tank bob, not the times when the fuel has air and the bob may have momentarily breached the fuel, especially more as the tank empties. You'll have to go back to the motor manual and set the needles to it, follow it's recommendations. and factor for the tuned pipe which I think allows less fuel to be used by the motor.

Collective management? That's less about bogging the motor as it is about flying the heli like a plank and not heavily loading the disc when motor rpm will drop, about using less collective pitch than ele/ail inputs to actually "FLY" the heli. It's like going from negative to positive pitch in a way that the transition is about maintaining head speed, not about expecting the motor to torque pull like an electric will. Smacking a nitro heli would depend on fitting a more powerful motor like a 90 which guys have but I see your not into smacking your heli.

You should look into a governor for the motor (if it isn't governed already) as well as fitting the header tank, and run out the last fuel from the carb by pinching the fuel line right before it as it idles and your ready for storage so fuel isn't in the carb and takes on water, nitro absorbs moisture from the air, this is the only way it goes bad and bad nitro on a glow spells bad things and poor performance. I like the muffler plug btw.

Have fun out there.

 

Hey man

Thanks for all that informations and suggestions. I will see what I can do to optimize the performance. Yesterday I was flying and my Align DS655 tail servo died mid air. I could land the heli so I have no more damages. Now thats my third Align tail servo which burned the poti.... Nice!

But Crash heligod still didnt get me! LoL
