Try the method modellor suggested. Else, bend the throttle linkage so that it clears the tank support.

When new, the belt can be a little tight. That's normal and it'll get loose once the car gets onto the track for a few tanks.

What I do is I normally put the side belt onto the 18T rear side pulley on the main 2 speed shaft first. Then wrap the belt partially onto the 24T front side pulley as much as you can from the bottom side. Once the belt is partially in, turn one of the front one way wheel BACKWARDS. The belt will automatically be in the pulley groove. It may need a little force.

Ummm, it looks like for your case if the problem of steering servo mounting can already be solved with the stock servo saver, going with a 1/8th scale servo saver would get your into problems It's like 2 rights will end up in a wrong.

In your case, you should use it still and remove some material on the servo saver like what Mark has suggested because it gives a better Ackerman steering.
my stock servo saver is juz clear of the lower part of the front belt. i juz wanna tried wif a 1/8 servo saver, does the steering improve.

The 1/8th scale servo saver provides for better Ackerman steering.

Have you tried using the FC steering blocks?

I always set mine to 100%. I have never changed it and if there is something that needs to be done on the steering setup to increase steering, I do it on the car itself via droop, tire selection or the shocks.

Torx screws are nice However, you can alternatively get allen type M4 countersunk screws from any hardware shop. I find for me they strip less and easier to work on.

If you have a T type 2.5 mm allen wrench, you can really tighten them down. With this, I do not need to use any thread lock on the engine mounts.

Perhaps another tip that I can share with you is to use reduce the rear trackwidth. Have you measured them? If you're using a rear camber of -4 and a toe in or +2 or +3, you'll definitely exceed 200mm. I find that by reducing the rear trackwidth to less than 200 mm gives me a lot of turn in and the car will transition from left and right in the chicanes very responsively.

I find that reducing the rear trackwidth while increasing steering does not compromise on the rear traction.

Ummm, the thing is the torx screws (1014 or 1015) from Serpent is M5 and is meant for their Impact and Vector / 950 cars.

I feel for you but I I think you still need to get it outside a the hardware shop. If you still want to use Philips, then better get a proper Philips driver like the one from Hudy. Correct size will not make the Philips screws strip.

Default German Championship race

Just read a report from a competitor in the German Championship race:

http://www.mytsn.com/publ/publmem.asp?pid=8871

All in German however.

Steve Baumgarten (the driver) was very critical of the 705. He started by saying that just looking at the track he knew he was in for trouble with the 705. His first venture onto the track simply confirmed his worries!!
Fortuntaely he had a very experienced helper with him (Dieter Fliescher) who manged to transform the car. However after a rain storm and a once-again dry track the car reverted to an almost undriveable machine. Dieter made some small changes to the setup, which changed the handling of the 705 completely - here Steve was once again very critical, saying that sweet-spot of the car is very small and therefore difficult to find the right setup.
He concludes his report by stating that he finished 17th in the championship race and he was the highest serpent finisher - which he pointed out shows that the 705 isn't a good car!!!!

He certainly was not a happy bunny and Dieter tried to pour some oil on these troubled waters by saying that with the right setup the 705 was as fast as the Mugens and the Assos'. But he also sort of admitted that the 705 wasn't the best by saying that he hopes for a real strong car for next year - a nod to the 705's successor.

This almost sounds like the things which were said about the Veteq and Vector NT just before the 950 came about! Hopefully the next 200mm Serpent will be as good as the 1/8th 950.

Cheers, Mark.

I'll try again:

http://www.mytsn.com/publ/publ.asp?pid=8872&eid=1326

It seems the link changed somehow - maybe Serpent censoring!!!!!!!!!!!!!!!!!

To me it was him trying to make a point about the new car coming - not in so many words, but maybe he felt somehow frustrated about the car and now that he knows a new one is coming, he felt he could let rip.
