why would you want something like that? The stock system is one of the easiest I've ever used.

Kingheadz & Reckward Tuning (RMV) are the one's I remember.

hmm, good question Ali. I use this chart here to determine what wt/cts to run in the shocks. http://www.twf8.ws/php/tip/shock.html I believe this was before Ultimate came out with their shock oils. Check the bottle to see if they have a cts rating on there. The chart link above tells us the Losi 40wt is supposedly around 550 cts, but if you look at other brands like Serpent 40wt, its over 1000 cts; therefore you really should make sure you know the cts before you put a specific brand of oil in your shocks. You could maybe send Ultimate an email regarding what the cts is of each wt they sell; that would be the best option I think.

My original rear bulkhead finally died this past weekend racing in RC Pro International Finals. I guess I should have chaged it to "C" version b/c it broke while I was running 2nd in B-Main ready to bumped to A.

I read somewhere that a stiff engine mount will allow the engine to work better as there is less stress on the engine body. From an engineering background, this has merits, not sure how much stress is introduced at the chassis to cause engien crankcase to warp and rob valuable power?

apparently this phenomena is not as obvious with 'old school' engine brands like OPS, Picco, Rossi... and more apparent with 'newer' engine makers; OS, Novarossi, Sirio, GRP

Not that I am lacking power, just thought it might help keep the engine healthy longer

Hey Kendall, thanks for your input, ill check with our Ultimate racing dealer, i'f am not mistaking , 40= 400cts 45=450cts ...etc etc
i normally run 40 rear 45 front when the weather is a bit cold, sometime i drop to 40/35 when its freezing cold....when the temp raises, i go to 55/60.

my other question: the stock pistons are 8/1.2 right?? now, why would i want to change to the newer ones like the 8/1.3 or the 6/1.4 or 5 i'm not sure, will i really feel it while driving?? how will you explain it easily for us, i mean can you tell us what type of track needs what?? do you see what am sayin?

cheers

Slayyer, those are the numbers for the Ultimate oils?

Ali,
Yes made perfect sense. Yep, stock pistons are 1.2x8 on the TKI, but I have heard it comes with 1.2 and 1.3 on the SE? (I don't have the SE yet) Changing pistons is all about personal preference and what the track is doing. For example, the RC X Fest race up here in Minnesota is known to be a very rough and sandy track. In this case, some may want to go more holes in their pistons (rear especially). This will give the suspension "less pack" and go over the rough better. So instead of 1.3x8/ 32.5 wt Losi in my rear shocks, I drilled them out and ran 1.3 x10/ 35wt Losi. You have to go up in oil to compensate for more holes.

Typically, one would want to run more holes for more side bite, and less holes for less side bite and response. Notice how on the STRR, mostly everyone runs 1.3x6, this is so we are able to slide the trucks around a bit more through the turns. If you have an extremely smooth track, I could see going to a 1.3x6 or 1.4x5 piston. The car would generate less chassis roll and could be faster. On the old 777 we used to run 1.3x6 on the front and 1.3x8 rear to calm the car down, the same can be said for running 1.2 front and 1.3 rear on the MP9. Kyosho also makes angled pistons. These will make the car feel stiffer landing jumps, and would make the car pop more off the jumps. So far I haven't noticed too much of a difference between the angled and straight pistons though.

Usually I will have specific oils to run with specific pistons. If I run 1.2x8 front pistons, I'll throw in 35 wt Losi. Now I have 1.4x8 angled/ 40wt Losi. Rears- 1.2x8/ 25wt, 1.3x8/ 32.5wt, 1.3x10/ 35wt. Once I tried the rear shocks in hole number 2 on the tower (second from inside) with 40 wt, that worked pretty good as well. Had to go to a thicker oil to compensate for the low, soft shock angle. I might go up or down 2.5 wt depending on what I want the car to do, but those piston settings are pretty much what I run.

You have the adjusting temperature/oil settings down pretty good. I personally don't change oil too much depending on temp because the Losi oil doesn't change viscosity a whole lot. I will only go +/- 2.5 - 5wt in say a 30-50F degree temperature change.

Hope that helps

Kendall

I always use the stock filter cage, I've seen others not use it. I think either way would work fine.
