need HELP

[jlr3rd1]

NEEDING SOME HELP I changed the drive and steering rudder and now when running the boat slow its ok but as soon as it starts to get some speed the right front wants to dive into the water until it flips ??? could the rudder be to far away from the drive ??? heres a pic??? any ideas

Try raising that strut bracket on the right side at least even with or above the hull.

Could be creating a dam effect and causing lots of resistance at speed.

thks i noticed that and moved it up?? will have to try again .

Yup, thats what I see also, square up the strut bracket and give it another go, should be fine

well after moving the bracket and rudder still the same thing?? so i raised the prop and drive up and that stoped the nose diving but now the flex shart is spinning at the collet nut?? the flex shaft i used was for proboat 1/12 hydro 235 mm as you can see in the picture it to short?? would i do better getting the 1/8 flex shaft???? BUT WHENS RUNNING IT SCREAMS :) 2 3S 25C LIPOS

and also the collet nut is striped as well

I would double check the flex shaft. I've had two of them break loose at the ferrule, which you can fix easily by soldering or JB weld.

In addition, the hydro flex shaft you mentioned (PRB2506)? is 9" long, much longer that the one in my BJ26SS (PRB3764) which is only 7.75" long. Hard to imagine it's not long enough. Granted mine is in the nitro version, but I can't believe the motor in the brushless version is that much further forward. It sure doesn't look like it comparing the interior pics of the two.

Checking the shaft - ferrule connection may save you from a new collet, which isn't exactly cheap at about $30. Good luck!

well got another flex shaft and to short every time i try to run the 6s lipos there is not enough shaft in the collect and just spins!! so i had to remove some wood and move the motor back :) now i have had three trips to the pond and it s holding, and does it draw a crowd :) the thing FLYS

When I changed my hardware I just got a long flex shaft and cut it to the length I needed,
I followed the tech tips I found some where in this forum and it worked great.
You use some green loc tight to secure the prop shaft to the flex shaft instead of trying to silver soldering it, works just fine, and I'll find out just how good it works when I run 2s1p
5000 mah with 40c w/ 50c burst lipos, but anyway I still have enough flex cable to make even another cable.
best of luck . later G-UNIT
