Aerobatic 3D Contest > losing forward speed at the exit of a roll; why?

I can do rolls now without too much trouble but......when I exit the roll I have lost almost all my forward airspeed. I always enter with plenty of forward airspeed so I know I can't have a problem there.

Anyone have the answer for keeping the airspeed up through the exit of the roll?

roll

You may think or see that you did a roll, but if you put a magnifying glass to it, your roll is more likely a little distorted barrel roll.
Keep practicing, because it's a good combination of aileron and pitch/throttle input. Any slight addition of rudder and elevator will hinder forward flight after the roll.
So the next time you fly keep your mind in controlling only the aileron and pitch/throttle lever.

I found that the balance of the helicopter has a marked affect. Additionally, if you are accustomed to flying with with nose down trim, it causes the nose to drop (rise inverted). When I got the balance and trim right rolls both directions became much easier. (Initially LH rolls were better looking than RH)

jb,

the answer to your question is easy. You are applying slight forward cyclic to keep your heli in upright fast forward flight. By the time you roll upside down, that forward cyclic needs to have been changed to gentle aft cyclic but instead YOU are pulling the stick back too little too late or not at all. That is why you're losing your airspeed. You probably know this already.

In the roll, by the time the heli is knife edge, your right stick should have been pulled back to neutral from its initially slightly forward position, maybe even sooner, like as you enter the roll let off on the gentle forward pressure. For the completion of the roll to upright flight, reverse the above directions.

Break up the full roll into two maneuvers, a 180º roll to inverted & a 180º roll to upright. Practice your fore/aft cyclic timing until your airspeed does not decay in the two maneuvers. Later, put the two together for the 360º roll. After that, you can start the whole thing over again with tailfirst rolling. ;-) All of the above helped me with my rolling.

one other thing..

Try your rolls downwind at first, this helps you maintain your speed. It is a timing thing with the left stick to get a good axial roll that will not decay the forward speed.
