I'm probably going to get dirty looks and comments for this, but whatever,
hyperc10 look at the Hobbymate US SHIP Hobbymate 3 Axis 3 Axis FBL Gyro for 250 700 Flybarless RC Helicopters | eBay
it is a beast clone, there are tons of reviews on other forums for this fbl board, I have not personally used this one, but I do have a Bigaole brand one that is discontinued and it does just fine. A friend of mine had it and all he uses is BX said it was pretty close to being exactly the same. I think that Bigaole is hobbymate now.
