gun 17.5 brushless???
as this will be the new 27t spec motor i'm curious as to what everyone thinks about the different brands and if there are optional rotors for those brands?? As i'm a bit of a tight a**e with money and dont want to have to buy more than one!!!!!! lol

optional rotors exist for most of the brand of brushless motors, but not legal to change out on the 17.5 class. I will have an idea after the weekend. I have run the novak and lrp and will run the Speed Passion and Hacker/losi today. these are all in a 1/12 car on carpet

cool sounds good i know the importer of speed passion in aus so i was kinda hoping they were good cause i can get for a good price locally but if the novak or lrp are better for overall gearing and speed, power balance then ill just get one of them seeing that you only really need to buy one every so often

Novak - I had it geared at an 81mm roll out. that was basically the fastest on our track. this gave me good straight away speed and great out of the corner acceleration. You could to + or - 1 tooth and be able to run the same lap times. motor temp was around 155-160
LRP - I had great this at an 81mm the first run and it faded about the 6min mark. the thing was just as fast as the novak, but I lost alomst .3sec in the last 10 laps. On the second run I dropped the gearing down to a 80mm roll out and it was right on pace as the novak with no fade. I was able to run the same laptime at the begining all the way to lap 42. At the 80mm roll out, it seam to be more consistent then the novak. motor temp was around 150-160
SP - Same as the LRP. At the 81mm roll out the motor faded. at the 80mm roll out is was very consistent from beginning to end. motor temp was in the 140 range.
All in All, the are very similar in performance to each other. I find the novak to be more forgiving in gearing. you can be off 1 tooth either way and be right on pace. with the LRP and SP, 1 tooth off and the motor is either slower or fades. but the LRP and SP seam to be more consistent when you are running the right gearing. None of the motor were setup for top speed. by the 2/3 mark on the front straight, you could hear the motors hit the limit and basically were freewheeling the last 1/3 of the straight. it is just like a rev limiter in your 1:1 car.
I have done all my testing in my 1/12 with a lrp sphere speedo. This combo has been in my car for 3 years and I know the characteristics of the speedo well.
Next will be speedo testing. I have the new SP GT LFP 1.1 speedo I will run next weekend with my novak 17.5

i di dnot get a change to run the hacker/losi this past weekend. but here are the other 3. this is all in 1/12.

I have been wondering the same thing as well. thanks for the report.

thanks that was the info i was hoping for! so it dont really matter which one i get what ever is easier!!!! lol or cheaper. But if what you say is very similar in touring car to, then stock racing is really going to be good then. well i suppose there will still be slight battery wars but i think if your packs are less than 3 months old it dont matter to much they go good anyway!!

well if you add 6 cell to the equation and all the extra drive train, my point is they should be quite even and it would come more or less to car setup and driving!!!! i just hate when you have a stock car that is 2 times quicker down the straight!! especially when there setup sucks but there speed keeps them very close!!!! lol

so if everything was perfect in a perfect world, then yes they are basically the same speed. in my opinion there is quite a big difference between the 3 motors. if you want to be in the ball park, then the novak will do ya. if you want to be dead on lap for lap then I would go with SP or LRP. but if you hate to work on gearing, I am talking 2 teeth in 64pitch on the spur, then I would stay away from LRP and SP.

I can't speak for the LRP, but I do have a SP Ultra Sportsman and a Novak.
The SP can be fast when it is geared high. The only thing is, in my racing environment, it gets too hot to run that kind of FDR for the length of a race. My Novak has been much more tolerant in terms of gearing and is my choice for my specific situation.

Hi,
I have just picked up a 17.5 Tekin Redline motor and wondering what gearing should I start with. The Novak site says their 17.5 should be geared at 3.5 FDR is that correct or close to the mark............
