i had just upgrade to the bh and also did the fuel tubing mod on the stock tx. i also removed the flybar weights so the response is even faster. but when your learnin with bh, your heli wont be as stable, so i'll think it actually makes it harder to learn on. i can tell you exactly because i cant go bak and be a beginner again. it'll take some time to get use to the faster response if you started with a bcp though.
