25.5 motor would be awesome! That will take care of the issues with slowing down the TransAm class and would be a great replacement for the silver can motors.

Why do you guys want to replace a reliable $15 silver can motor with $80 brushless motor?

In theory the lifetime cost of the brushless would be less. With competition the way it is, most folks would go right through that $80 in silver cans in a year or less just trying to find that one motor that can get them a win.

since in 540 racing, a good can doesnt cost 15, but in fact more like 45.

ask any1 who competed at tcs finals in mini, f1, gt3 or even spec how more efficient a 80$ 25.5 would compare budget wise, but then again those guys like their advantage and want to keep it as long as possible

As tall as a 21.5 has to be geared I wonder how a 25.5 will have to be geared?! Any more winds and Novak will have to devise a direct drive outrunner or something like that (hint, hint..).

Our local track, RC Performance, will still have 13.5 Sedan this winter for those that need to feel the pure speed. I would guess a 25.5 would just be unrestricted for FDR and end up being just a touch slower for classes like TA, Mini and F1. Most of us with 21.5s gear lighter than 4.2 in our TA cars already. My TA cars seem to like 4.4 to 5.0. I like the thought of driving skill and a clean race being more important than pure speed for the win for the classes I mentioned. Stock 17.5 Sedan is already enough of a challenge for me, but I'm having fun getting a handle on it.

We are winding the 25.5 Ballistic custom stators and should have them in the store in a week or so. We will also be adding ceramic bearings.

It would be interesting to see what kind of rpm you would get out the 25.5?

i ran the old 10.5 and new 10.5 back to back last night, stock timming on both motors, old motor had more speed down the straight, i had to gear up 2 t. on the new motor and 1 more notch advanced timming on the new motor. i was using an LRP stock spec profile 7, motor was comming off at 180-190. will be trying profile 8 next week. other than the slightly slower top speed the motor feels the same as the old ss.

Steve,

What would you think the Kv of a 25.5 motor would be?

I'm guessing close to 1,500 Kv, so I'm guessing "LOADED RPM" w/ a 2cell lipo would be around 6500 RPM

I would have to test it to be sure but I would guess anywhere between 1200 and 1500 like you estimated.

Again the loaded RPM is a guess as well because it depends on the load

If I have some time I will try to test this tomorrow but I have a feeling I will be pretty busy tomorrow with my preparations for IIC next week!

folks with tamiya mini's (and the hpi cup racer stuff), f1, and other '540' classes are already asking questions bout the 25.5

when roughly will we see 1, i'd actually like to try the idea w/some fellow racers as they get their indoor season started
