17.5 Non-Ramp... FACT vs. Fiction

17.5 Non-Ramp... FACT vs. Fiction
Hello all,
With the dissemination of ramping in the ROAR classes, I'm wondering what everyone has been seeing at their local track regarding the non-ramping stuff. What motors/esc combos have been successful at your local track? What gear ratios? I've heard of people making mods to their slipper clutches to try and get smaller spur gears on, etc etc.
Trying to get a feel for what I might need to purchase to get my whip running all flossy and ish.
I'm sure that if someone really has found the hot setup, they'd probably be reluctant to share it... but I figure it's worth a shot!

What do you mean by non ramp? Is that no esc timing? I have not heard that term.

No timing stock class 17.5 motor, gear it until your at around 160 degrees at the end of the race. If the motor isnt hot at the end of a run your not working it hard enough.

I've ran 3 different speedos and a few different motors with no timing.
GTB2, Havoc & Mamba Max Pro.
Speedo-wise (relative to the motor) all about the same. Some have more bells and whistles, better BEC, whatever you are looking for, but in the end, they perform pretty closely.
Motor-wise, I have seen big differences, even between same manufacter/same model. Novak SS 17.5, had one that was very fast, one very slow. Losi Xcelrion same, fast one and slow one. Trinity Duo 1 was really fast (after adjusting the limited timing advance).
Biggest difference I saw was with burst rate (C) on the lipo, and smooth driving...I now only run my Losi shorty pack (60C) when running no timing 17.5. Lightens the car up and just feels really quick.
I run a 22 geared @ 35~37/72 or my RC10CE geared @ 33~35/75.

i greared my 22, 35/69 using a.e. slipper set up slighly smaller than losi to fit properly and of course the infamouse D3 motor, RS Pro in blinky mode. nice and fast.

At the top echelon of racing, it WILL matter what motor I'm running... so i'm using this forum as a means of surveying and asking people what they've been successful with or what they've seen at their local tracks yield success. I don't have the money to buy every 17.5 out there, nor the time to go out and test each one.
Driving clean will only get you so far in stock racing... you gotta have the whole package. The guys in front will have found a couple tenths a lap, which will equate to seconds at the end of a 6 minute run.
FACT.

^^^^ I agree, I like stock class racing, at the club level. For most club level drivers, the speeds in the stock class make for some good racing, better racing than if most of these guys were to run mod. This is the part that sucks, once the top club guys reach the point that the driver isn't the major factor anymore (as in the top few drivers are all good and can all run up front) it turns into a money game, best, latest and greatest motor of the week club..
If you can drive~ mod classes show driver skill, stock classes show who has the fattest wallet...
