Alright. Two summers ago I purchased a 2.5R Revo. The 2.5R engine always seemed peppy to me, but I had been hearing about how people were pulling mad wheelies and achieving blistering acceleration with it, and I was feeling stupid. I was beginning to question my tuning abilities as a result of it combined with my pesky carburetor that didn't hold a tune very well.
So I got the OS .18TM and I was shocked by how powerful it was. Infinitely better powerband, easier to tune, very flexible in terms of the power it makes regardless of how poorly it is tuned. I think I lifted the front wheels once this past summer, three inches off the ground after I hit a rock, and although part of me was pleased, I was disappointed in the power delivery as well.
WELL! I installed the LT rockers this Thanksgiving break and as I was doing so, I was reading about how the slipper clutch was set from the factory. It says that the spur should just barely be moveable with a FINGER while holding the shaft in place with a hex driver or the equivalent. I started thinking "if I can move it with my finger, what's this TM doing to it?", so I cranked it down a little bit and ran it the next day. I got it running, brought it to a rich setting to let it get going, then floored it from a standstill. It didn't move further than 2 feet from the resting position, as it flipped over in place! :wow: And this was running rich! Over the course of about 20 minutes, I discovered the true power of the .18TM and the acceleration that can be achieved with it. I will be installing the 36t spur before I try to run it again, to get more controllable acceration runs as well as better top speed.
Working on the Revo also made me appreciate how easy it is to disassemble and clean, as well as it's super slick design. It just made me happy to have my RC cars.
It makes me want to get my Savage SS with the 3-speed out of the box, crank down on the slipper a bit, and see if it will pull wheelies with my newfound knowledge!
I just thought I'd mention this both for laughs, and if anyone else has wondered if their car seems like it should be achieving more. :D
