Fixing the BJ26 Handling Issues

[Jesse J]

First of all, I have read the thread several times. There is a lot of information, so forgive me if I missed a detail. I am fully aware of the title, since that is what interested me in this thread. I have participated in the spirit of improving the handling of the BJ and since I almost bought the BJ, but can't afford it, I have to make my own. I don't know why this should solicit sarcastic remarks...

The handling issues I asked you about were regarding the removing of the second step on rockwerks mods, I have seen your video several times and didn't notice any catching on the inner sponson due to the second step. Since I was not driving it in your video, and I know handling is "felt" through the transmitter, I thought I would ask you your opinion on this "handling of the BJ".

Personally, I think my interaction in this thread is completely appropriate since modifying an existing hull that is "not the hull to copy" is not too far from making your own that is the same dimensions and trying to learn from people who have been changing it through experience.

I think it is too cool when people that love to work on FE boats also are willing to share their modifications and are also glad to explain why they changed them. This helps everybody, even those who are trying to design their own boat and avoid poor handling when they are done.

Just messin with you a bit

The sport only gets better with free and active participation and sharing of ideas

From what Ive read here and elsewhere the steps in the cat hull pretty much have a null effect on speed and do affect cornering as the inner lip is broken instead of continuous. The effect is the same as a mono would be if you where to split up the strakes into short broke lines, not a good thing. On a 1:1 offshore rig where the boat is displacing many tons the steps help lift the boat out of the water. On our small scale we are only lifting several pounds of weight and the effects are not the same. We can push the envelope because of the size of our rigs

Right on, I'm game for messin, just have a knee-jerk reaction to stuffiness

Have you had a chance to do that rounding on the hull and see what it did on the water? Gotta pic to help me visualize?

hi

Ive got a stock BJ 26, running with 2x Zippy-H 11.1v 5000mah 20-30c. Having problems keeping it from flipping over when I try to use the throttle. To much torque basicly. I really don't care that much about the handling while cornering, but my main goal is to get the boat stable enough so its possible to launch without flipping over(loop basicly) and keep it from flipping and barrel rolling while reaching top speed.

Would like to keep it stock as much as possible.

Any ideas people?

Great thread btw, fun reading about so many different ideas and solutions - Very interesting. Keep it up :)

try proping down or moving the CofG further forward make sure your strut is set right

well thats my guess !!

[Apples1]

batts as far forward as possible, and drop the strut as low as possible, prop down maybe?

[robin4]

hey

solved the problem i think. I adjusted the tilt a littlebit, and got rid of the battery"holders", and got the CoG much lower, and it worked perfectly at topspeed. worked ok from launch too

So Thanx for all the help guys :)

Take it out and rub it on, and re-install it!

practical........HHHHHHHMMMMMMMMMM no, cool YES!

[shadow9823]

so the only way i can do that is if the BJ came with two motors and not one...ook cool
