1725 grams when the car comes off the track....In other words you want to weigh your car with a smaller set of tires and a empty fuel tank...If your car weighs about 1755 when it goes on the track you should be good but no guarantees.....

They always weigh the car after the race. But i always ask if they can weigh it before so i know i'm right with the weight.
My car is very close, about 1705(efra).

yeah as soon as your done with your qualifier or main the car goes to tech, where they will dump out any remaining fuel and than weigh your car 1725(roar rules), but the only time you really have to worry about weighing the car is at the bigger races i.e. Capitol Classic, RC Pro Series, I-95 challenge, events like these i've never had my car weighed at a club race....

besides the build tips that Xray gives in their manuel, what other tips can be used for a build? like polishing endballs? what type of polish? what technique? sealing the edges of the graphite parts... do i use super glue? what about threadlock? whats the best type and color? and any other tips specific to the NTI would be very helpful..thanks

Blue thread lock and as for polishing this kit goes together well no need to polish anything imo as for the graphite you can seal it if you like (i dont) yes any ca glue or super glue.

When you seal the graphite, use CA glue on a Q-tip. Less mess and allows a much cleaner finish. I usually give two coats - you can give a light sanding in between if you want a really smooth finish.

Also, early kits had very loose threads on the pillow balls and the lock nuts. Some people have used thread lock here as well, or even scored the plastic thread with a small screw driver to give it more bite. Not sure whether it was rectified in later kits but if they feel loose you may want to use a bit more of the blue thread lock.

The only polish that I found useful was all of the hinge pins. Set them into an electric drill and polish with a good metal polish like Autosol. This can help with a smooth suspension arm action - you want the arms to move freely and drop under their own weight without shocks attached.

Also check that when you fit the rollover bar/handle, you do not tweak the upper deck. If you are bothered by this and need to leave the screws a bit loose in order not to tweak it, make sure you use some thread lock or they will vibrate out. During my last rebuild I tightend the handle up - the top plate tweaked a bit but personally I do not think it will translate into any real problems such as you experience with a tweak top deck on an electric car. Others may disagree - just my view.

Good luck.

sounds like you have implemented the well taught electric OCD methods to building the Nt1 teehomo
i useually glue the edges as well but i couldn't be bothered this time around, so i just painted them black with fascolour.

goes together well, the front lower arms have a bit of forward/back movement, otherwise nice. I lowered my tank 3.6mm as i amusing a lipo, i've added extra weight on the batteyr tray though.

i just built a set of alloy nt1 shocks, they are only 2 grams heavier than the plastic versions, so if you are using the plastic versions thinking they will be a sizable weight reduction you are wrong.

also i installed a lipo in my car and titanium pivot balls, it is some 100 grams under weight damn i didn't know they were this light!

does anyone make a 100gram battery tray? ...serious? anyone?

also the hard bumper is some 25 grams heavier than the stocky
