The blade pitch should be 0° at the lowest throttle stick posistion. You don't need and negative blade pitch while learning to hover.
Hover should be a half throttle stick position.

Did your tail touch the ground. When I started flying my hornet's tail touched the ground just slightly and because the bladegrips weren't holding the blades tight enough the small deacceleration in rpm made them advance and strike the boom. It looked very viscious! Whatever you do, don't make this setback er....set you back, once you have the hang of it these heli's are the coolest thing you'll ever play with.

+ Do not buy a stock boom, just buy some tube with the same dimensions and make it fit...will make your wallet much happier

adjusted pitch curves to 0%, low stick 10% high
This is where your problem lies. If you're only using 10% over all points of your pitch curve, that means you're using a very small percentage of total servo travel to get full pitch range. This could only mean that you have the links from the servos to the swashplates mounted at the last hole on the servo horn.

Also unless you're going to do 3D, you won't need 0% on the 1st point of the pitch curve. 0% on the pitch curve usually means maximum negative pitch! That explains why you had a boomstrike. When you lower your throttle, you're putting in full negative stick driving the heli into the ground and causing the blades to hit the boom.

The way my pitch curve is set up at the lowest stick position using my micro pitch gauge it reads out 0%. this is the frustrating part of it. the blade grips are snug and the whole heli was level only about 6-10 " off the ground. can this be a case of head component flex?

The stock parts of the Hornet work well are not causing your problem. Your profile say you have a Raptor 50. Can you fly this well and set it up yourself. The hornet 2 is harder to setup and fly than the raptor. Your problem only sounds like a setup issue. Is the fly bar paddle perfectly aligned? Is the swash plate level when the stick is centered? Is the heli balancing at the main shaft both front to back and left to right? Good luck.
