The other day, it was suggested that I learn better collective management, what exactly is that, and how would I be advised to attain that. (I think it has something to do with trying to keep the head loaded about the same at all times if possible, but I am not sure). Is this one of those things that can be practiced on G2? or is it one of those Burn more fuel issues (what isn't but yeah)



thanks

Collective management is when you dont keep boging the engine down.

Heres what Curtis K says about engine management...If Your heli is boging down with a 60 size engine in it, and you decide its not enough power. SO you get a 91 in it. guess what, its still boging down the engine. Why? because your probably going full stick and full collective to do the trick. if its bogging down the engine during a piro flip, back off the collective. Instead of going 100% both ways, go only 80 %. it will keep the engine running near the same.

You can practice on g2, but try not useing a govenor.

lots of times its easy to exceed the boundaries of the engines on heli setup..I think its best to set the heli to the engine rather than the other way around.....

for something like a muffler equipped 30 size heli, +/- 8.5 deg pitch in id2 and no more than 6 deg cyclic travel, 20 to 30% cyclic/throttle mixing + a limiter ring on the radio will take some effort to bog my OS 32....its no powerhouse but thats not the point I wanna make: the setup has to be whatever keeps the headspeed constant doing whatever you can dish out, thats it. A governor could also help after finding the engine's happy range.

collective management is more or less the proper timing of the collective to do what you want when the helicopter is rotating on either the pitch or roll axis. yaw isnt much of a demand to the engine usually, but it could be included if you are doing very fast piros.

it seems that when we learn a new maneuver we give as much cyclic as possible and bog it like Corey says...in a perfect world you want to use less, when inputting one or both cyclic axes commands, and the limiter rings really help in that department when you are tapped out. You're right though Greg, it seems stick time is a big one (even if you have a fair amount of stick time, these things are still easy to forget how to fly after a few breaks ), but if the model on the simulator accurately simulates the characteristics of your model, or has less power, then the sim will help as well.

just dont cheat yourself on the sim, use a "wuss" heli to do 3-d, its sim time well spent.
