Yes, it's Adam. And you are most welcome.

I wouldn't worry about the throttle curve being linear below the hover point. Just make sure the throttle comes in so the rotor speed gets progressively faster until you reach liftoff. Avoid a throttle curve that causes the rotor to overspeed before lift off, and then slow down again as you approach hover pitch--that means you're bringing the throttle up too fast below the hover point.

I use idle bar plugs sometimes in my planks too, but the OS #8 is really great for this engine. Enya #3 works well also.

Don't forget to spend some time on the bench with your pitch guage to make sure you know where the stick is at 5-5.5 degrees of pitch. Also, you need to take the engine out to reset the low end needle...it's the only way to do it properly because you need to sight down the barrel of the carb to find the correct position of the needle.

Best of luck
