weight distribution for x6 squared

[Bepe]

Hi,

I was wondering if there is any advice available for setting up an x6 sq with additional weights, mostly around the front. I have heard of the 65/35 weight ratio but seen a lot of different amounts of weight used when investigating on line. Use the car on carpet with wooden ramps and yellow mini pins. Have around 110gms (total) in the two triangular openings at front of chassis and 4x15gm squares stuck at the front of each of the channels where the nicad stick pack would go. Still seems to land on its ass when i jump. Should i put more weight closer to the front or just practice jumping more. And what is the deal with changing direction in the air? Cannot make it work consistantly.

Cheers.
