latest upgrades

i have now gone back to Kyosho LA-26 arms, and i modified the A & L bellcranks after i found their shortcomings. the problems was the plastic 4-40 nuts were not strong enough to hold the screws. after a few hard knocks it worked loose. so i replaced the 4-40 screws and nuts with M3x25L bolts.
Notice the missing bearing on the left, lost it on a bad day, waiting for the replacement to come. notice i flipped the graphite bar upside down from the instructions, this allowed me to place the ballstuds facing up and higher, thus enabling the steering link to be parallel with the lower arm, eliminating bump steer.

notice the amount of wahser under the pivot post to raise up the ballstuds.

The steering link is parallel to the lower arm, so no bump steer here !

Car now sits low with reduced droop , thanks to the New shock towers.
I tested the car now it finally it had a LOT of steering, becuase the bellcranks now work they way they should, and also because i grinded the back of the c hubs protrusion so that the knuckles can turn more. I just have to stab full throttle, when i want to turn let go then turn, the car will slow down by itslef becuase of the friction and grip of the front wheels. i can now point it to whiceever direction i want it to go to. but i havent tested it off road yet though.

More modifications...

Ok, the ZX-5 suspension was a dissapointment, not that it didnt work, becuase the width of the area going in the hingepins is short, it caused the hingepins to bend easily. So i decided to go back to the lazer ZX arms. Installed MPP ZX arms , which was a lucky find, i found 8 at hobby haven, each bag costs me RM5 only. Coupled to LA-59 front c hubs, and LA-28 rear hubs, i managed to laser-lise my Mid suspension. I like the lazer's arms better, becuase they place the outer hingepins inside the wheel, which makes rough track handling much better. I used the inner hole on the C hub to push out the front track, and used 3 racing 65.5 CVD. At the back, i am still waiting for LA245 CVD to arrive from japan. My A & L steering bellcrank arrived and cured the sloppy steering problem. I also managed to use back the Mids original battery holder system to hold my Lipo Saddle packs in. With Proline M3 soft tyres all around, my Mid will surely handle better.
