Slide Vs. Rotary Carb? - egglick - 02-03-2006 Hey guys. I've had my T-maxx for about 2 years now, though I'm still relatively inexperienced at tuning and such. I've only got around 2-2.5 gallons through the stock TRX2.5 motor, but since I haven't been using after-run (just WD-40) or keeping it completely clean (some external rust from grime), I don't think that it will last much longer. Once my TRX2.5 decides to call it quits, I'm looking at something like a OS .18 (CVRX) as a replacement. I see a couple different carburetor options on new engines, and I was wondering......what the difference is between a slide-valve and a rotary carb?? As I mentioned earlier, I'm not the best at tuning, so that's something to keep in mind. Slide Vs. Rotary Carb? - Tex - 02-03-2006 Welcome to the forums Kurt! You want the slide carb as you have now to complete a direct drop in installation. A rotary carb on a t-maxx has issues with the linkage hitting the spur gear in a roll over. Performance wise, the slide carb is supposed to be better in some way but I never noticed a difference. I've had both. Slide Vs.

Here is the one you want for the 2.5 maxx: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGGP6&P=ML They raised the price $10 because they have a sale going on. You need this too for the clutch: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJF69&P=M Here is the header and pipe combo I use: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXAXN1&P=M http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXSP47&P=ML Tower hobbies raised the price on that pipe too. You should be able to get one on ebay for like $15. Heres some pics of mine: Slide Vs. Rotary Carb? - FreeRideFrosty - 02-03-2006 Awesome setup rob and not at all pricy. That is about what I ran on my RC10GT. Hehehe... lots of power and ver reliable. As for carbs... I have used both and if you set the linkages up right I have neer noticed a difference. Slide Vs. Rotary Carb? - UE-Maxx - 02-03-2006 I have that engine in my maxx right now. Great engine. Rob, do you still run the stock motor mount? I am guessing that that is an old picture. Slide Vs.

Old picture, I sold it to bottledbeast.... he probably broke it by now. :p: I now run the dace mount. Slide Vs. Rotary Carb? - egglick - 02-03-2006 Thanks for your help guys. If the linkage on a rotary is going to have issues on a T-maxx, then I guess that makes the decision easy. I was kinda wondering how two differ in power and tunability though....just for future reference. They're both the same price, so I figured there must be some minor tradeoffs. Slide Vs. Rotary Carb? - FreeRideFrosty - 02-03-2006 Some say the power from a slide is more predictable as the opening always changes by the same amount but I cannot notice a difference. They tune the same from what I can tell as well. The only thing is that a better carb will hold a tune and be easier to tune than a cheaper carb... Slide Vs.

Rotary Carb? - The_Thubbed_One - 02-05-2006 A book would say that the airflow thorugh a slide carb is going to be easier because it's going staright through, versus having to go around both sides of the ball valve that a rotary carb uses. so the air has to do this _/- instead of this ----. Once the throttle is wide open, there is no difference. Hopefully my diagrams make some sense to somebody other than me. |
