I would like to know what problems that the 705 has that you're hearing... No durability issues. Problems only come when you assemble the kit wrongly.

If you know how to setup a car, you can make any car for that matter to handle the way you want it to.

Like Slotmachine mentioned, if you think 180x80 track is too tight for the Serpent, then any other track would be too huge for the 705 You should be lucky to run on that track size. The place where I come from, you would be lucky if you can get to run a straights of 150 feet

Yes, the MTX-3 is very well suited for small and tight tracks because of the internal drive ratio and the gearing. You can also make the 705 work good on smaller tracks... No, not like the 180x80 track that you mentioned Smaller than that You can change the stock pinions (16/19) to 15/18. If you need better acceleration, it's just a matter of changing the internal pulleys to change to a better internal drive ratio.

Any more questions, please ask We don't bite

Go to www.mytsn.com

Yes, they are all competitive cars and in the hands of good drivers.

Ummm, just curious... What engine are you planning to put on the car? If you're planning to get a pullstart engine, I think only NTC3 can fit it in.

In any case, if you're bashing, the engine is fine. If you're racing, then you need a rear exhaust non pullstart engine which the MTX-3, NTC3 and the 705 will except.

Putting shims under the front bulkhead would increase the front rollcenter. Increasing the front roll center makes the front rather more difficult to roll. You decrease the front traction but you make the car easier to switch directions. For the front, Serpent team drivers in Holland reported that they used 2 mm shims. You can test different amounts and see what happens. When you add shims under the front bearing block, you need to raise the radio plate by the same amount by putting the same amount of shims on the radio tray support (X bar). You also need to reduce the same where the fuel tank sits.

You can also alter the front rollcenter by using smaller front tires and maintaining the same ride height. This makes the front arms more angled and thus raising the front rollcenter.

Same goes for the rear. However for the rear, the 7 mm spacer (or other spacers) does this job of increasing the rear rollcenter. It does not mean that the rear roll center gets increase 7 mm directly. Just the way that the rear arms are more angled by the addition of this spacer will make the rear rollcenter higher. I don't have the exact figures that this turns out in direct increase of the rear rollcenter unlike if you put shims directly under the rear bearing blocks.

Once problem I forsee if you put shims under the rear bearing blocks on the 705... The side carbon graphite stiffeners cannot be mounted directly into the rear bearing blocks because the holes will be offset as the rear bearing blocks would be lifted up a little. I don't think this would be a problem on the Impulse PRO though... Then again the 7 mm spacers on the rear uprights makes adding spacers under the rear bearing blocks redundant.

When you increase the shim on the rear arm,you change the camber gain under compression.Thats why almost all of the serpent guys change to 4.5m.m. because 7 m.m. is too Serpent is coming out with new sizes soon.

much!

You can't set-up ride ht. until all components are on the chassis.
