don't be sorry,nothing wrong with speaking but it might be an idea to get information before coming up like you've studied the BR for a few months after only a quick glance,many of the people on this forum can take a BR apart blindfolded and rebuilt it....lol
anyway as mentioned earlier,read the threads about your statements,you will learn a LOT

longer flight lighter and spare rotors in box or better harder rotors

I remember on a clone of the Air-surfer flying wing, there was a weight on a worm gear that would be spun to adjust the COG on the craft... Might be a useful tool for BR trim :-)

I think any of the suggestions here would be big improvements, but the only thing i would like is an extra set of blades in the box

yeah, Original Equipment Manufacturer. Sometimes a company will sell something under it's own label / brand that is actually manufactured (or "OEM'ed") by someone else.

How about a 4th chanel to give lateral movement via a COG shift?

jtyson : You are one of those people who just don't get it, aren't you ? The BR was designed to do nothing more than hover. AND THAT'S ALL !!! Not made to move forward, backward, sideways, or inside out. The rotor design is made to cause the BR to be stable when the bird is hovering, and whenever you attempt to make it go forward or backward, (an UNSTABLE condition), the machine automatically tries to correct the unstable condition and return to a stable condition (hover), whether you like it or not. And the same holds true for sideways motion !

In order to get actual forward, backward, or sideways flight, you need a swash plate affair in order to change the pitch of the blades at various places in the circular path of the blades. All the weight transfer devices you can dream up are not going to change the way the BR recovers itself when put in an unstable attitude.

If you want to fly like a real helicopter, go get your hands on a Hirobo XRB SR, or something similar. Anything that has a swash plate. One of the reasons the BR is so inexpensive is because it doesn't have the complicated mechanisms that are required to make it fly like regular helicopters.

If you have the ability to read somewhat technical stuff (other than Batman comic books) here is a website that explains how helicopters work.

Weight shifting will and does work. In the same way as attaching a weight to the front of the BR makes it move forward (albeit slowly because of the natural stability). Having just tried attaching a piece of blue tack to each skid in turn I can confirm you get a slow drift in the direction of the weighted skid. It is not going to win any prizes for speed but then again neither is the forward/reverse movement either. I would image the problem would be in getting a light servo. However, you could fix the servo arm to the frame and use the servo itself as the weight to be moved. You also need another channel on the board of course.
