Props to whoever TQ'd with the below 12000 rpm silver can at race #151. But how can you brag about 2 different race...its a different track layout, temp, drivers and equipments. Different situation.

......just making note that sometimes a $50 silver can isn't appropriate for the task at hand.

Hey Greg..I totally agree with you. I remember my first race with my mini. I was getting blasted on the straightaway. It doesn't make sense to buy a $50 silver can. I feel you man. I'm glad Fred made the rule changes.

We actually discourage people from putting too much power in their F1's. I know that some guys love the brushless & mod F1 stuff, but to me it seems like overkill.

A 15K is about the most we recommend for just about anybody, and that's for super high traction venues. Some of the monster tracks with really long straights can take advantage of the higher RPM, but there aren't too many of them that run an F1 class. Speedworld does, and they love the big monster motors.

But...generally speaking, the cars are so light that with macho power most guys spin the tires instead of getting forward grip. A 12-13.5K motor in an F1 geared at 50-52mm of rollout is more than most drivers (and the 103/104 chassis) can handle.

A group of us in So Cal. have been running a monthly event with strictly F1 cars for the last 6 months or so at several venues in the area. These tracks range from short and long track outdoor parking lot asphalt, indoor highly prepped asphalt and carpet. At the current time we have limited the motor options to silver can or 21.5 with non-timing advanced ESCs. In our experience, the 21.5 BL has some advantages but time and time again it comes down to driver skill earning the podium spots at the end of the day.

Personally, I recently converted over to a 21.5 ballistic in my F103. For raw speed, it is not that far off a good new silver can. Power is very manageable. The BL stays cooler, uses about 25% less battery, has no noticeable fade at the 5 minute mark (we run up to 10 minute heats), and the end bell does not pop off if you get knocked into the boards.

BTW: This Sunday we are having another all F1 day at WCRC. It is a fast paced day and is finished up before the off road program starts at 3PM. Just enough time to charge between rounds. Racing starts around 11. Doors officially open at 10 AM. meet in the Parking lot at 9.

Nice thing about a 21.5 is that you can tune it for whatever speed you want, or need.
And the durability of the Tekin RS Redline combo is fantastic.

At Camarillo we run full power with the 21.5, it is a semi-open layout with decent grip, where you can put the power to the pavement !

At the UF1 rounds we simply pull all of the timing out of the motor, and esc for very tight racing at a different pace.

A racer shouldn't have to have buy a "demon tweaked" motor just to compete.
With BL you have more than enough at hand and it is more based on driver/setup. as F1 should be, this is not the Mini class

At the 2008 Aliso Regional (yes, a big track), with a 15K RPM limit, the top two GT-3 qualifiers had motors dynoed by Fred at 11,000 and 11,100 rpm. There is something still to be said about driving.

There's even more to be said about running a fixed ratio class like mini. GT3 and F103/104 allow any gearing combination you wish, so you can compensate for a lower RPM motor. Not so easy with the mini..........

My Memphis GT3 car last year was running a box-stock Nats motor that barely turned 11.5k, but it was a missile geared correctly. Unfortunately, that same motor turned my mini into a back-marker in Omaha.

Default Pandora's box, now open

I guess what I will never understand is if you want "mini missles" or "monster" mini motors and just have to have that 15K, 17K, 18K or 20K rpm silver can to be "so fast", why are you racing mini ? Why not run GT-2 with a 17.5 or GT-1 with a 13.5 if it is speed you are craving ?

I have a friend who just visited Australia and they are big on silver can racing where he was at. The local fast guy where he visited is running a Tamiya 416 with a silver can. Come on, a $ 500.00 kit with no electronics just to run a silver can ?

Because mini is a cheap, affordable entry level class where everyone runs identical gear ratios and motors.

F1 also lets you gear to motor's sweet spot, instead of being stuck in a chassis that has a fixed rollout. I TQ'd and won F103 @ TCS #151, my motor was about 13k. I couldve used a 15k, but I also couldve gone up in rollout (I didnt want to rebuild my diff to change to the small spur ). Running F1 GB last season, I was just about able to keep up with Red Dot's with a stock can by gearing up, just shows how open gear tends to level the motor field a bit

Exactly..I'm hooked on minis!!! Now its even funner since Fred limits the rpm.
