OK here is my wrap up of the NT48.3 upgrade, when building the new updated truggy, forget all your set up's from the previous chassis, the flex properties have changed and the new chassis is a great improvement, as most would know i have also been running the M2C chassis and again forget all your set up's from this chassis.

The new set up in the manual is fast and stable to drive, i myself have made some small changes after a day at my home track testing different changes, i moved the wheel base to 2mm behind the rear hub and 3mm in front, the truggy seems to rotate better for my driving style, a little more front wheel drive action for me too with 12/15/7 diff set up, 3.5 degree rear toe and went to 700/600 with the shocks and 10% rebound.

Really happy with the upgrades and cant wait as im heading to the NSW State Title event in 2 days time, so will get 3 solid days of testing done in a race format, will keep you posted when i get back from the event.

So if your upgrading to the NT48.3 complete kit, start with the book set up and adjust from there, If you purchased the chassis and using the NT48 complete kit, forget everything and down load the new chassis manual and start from scratch, you will not regret the new set up changes.

Which springs are you using?

You can find them on the Tekno site under the NT48.3. I always use my phone for this site and my phone won't copy the pdf text so I can paste it.

So the shocks felt pretty good with the cone side up?

My NT48 is giving me a problem when I got it on a starter box and turn the wheels left or right not even all the way to the lock. If the wheels are not turning and you slowly apply throttle it has a violent shake in the front. This is a brand new kit never been ran. Makes you think the front axle drive pins are to long binding on the arms at the out drives but it has tons of clearance. Or like the front drive line coupling is hitting Ackerman plate and it has good clearance. Tires are balanced. Once it gets to a higher spinning speed it smooths up and you can turn it to full lock in either direction and as long as you don't stop the wheels it is smooth. I have been through this thing like crazy and can not see any thing rubbing any where.

Red springs all round, you could go with 2 gold and 2 red if you want to smooth it out a little

Suspected this may be the case. Appreciate the info.

Jeff, recommend checking your end points with the truggy on the ground. It might be turning too far and the wheel is hitting the arm or steering turnbuckle. Also saw this recently when the ackerman plate was loose on the bell crank.
