Yesterday was my first raceday with the 17.5. I'm pleased with the results. The first thing I noticed, is that I'm not getting passed on the straight anymore. I had the same power as any of the fastest guys. I qualified 7th out of about 20 cars, and finished 5th in the A main. That's my best showing up here at Norcal, and I've only been back to onroad since mid last year.
I think with some fine tuning on my suspension, I have the ponies to compete now. I ended at 3.77 FDR, and 38° timing.

I raced this motor yesterday and had it geared at 3.8fdr in 17.5 blinky and it was average so i went to a 3.6 fdr and it definately liked that it shaved .7 of a second on my lap times so that was huge and the temps were at 150f so im happy with this motor thus far

I started at the 3.86/38°. I had a temp of about 115° after 3-4 minutes. I maxed out the timing and the temp rose to about 135-140. During my first qualifier, I lost a pinion gear but was on TQ pace at the time. Without another gear of the same size and the shop not having one, I went up a tooth. When I did that, I backed the timing back down to 38 to be on the safe side. I ran the next qualifier, and temped at 140°. I was on a slower pace in the second qual, but I think the track was a bit slower. I knocked it back one degree for the main, as I've heard not to let motors get above 140° in 17.5. In the main, the infield punch seemed adequate, but was a bit slow on the straight.
This was only the second time out with this car, so I was working with my setup quite a bit, as well. I wanted to get the motor, and the suspension close enough to get used to the layout, and have a good time. I am going to focus more on the motor the next time out, and hopefully find its REAL sweet spot.

I hear ya, I'm not quite finished figuring the gearing yet. I'll walk you through why/what I did.

For all those attending the Reedy Race I will be there supporting.
One thing that I'd like to know is with the different gearing mentioned above what timing did you use. I think this will help us better understand the gearing. Last piece is what ESC are you using.
Last year's Reedy I qualified fourth and ran gearing of 3.65 and did not use full timing.
I look forward to meeting and working with all of you.

Right now I'm using the Speed Passion GT 2.0. I'm at 37°. I won't be able to test anymore until the weekend before the Reedy. I'll share my results, then.

Got my 17.5 down to a rocket and cant get the temps over 108. Went up 2 teeth to 90/52 And everyone needs to know where to get the motor. Now I really need help get the 13.5 I just got to do the same. Any one have a fdr for and xray 2012 on the same track with an over 200 ft straight thanks in advance.

Anyone got any more close ups of the stator front and the magnet? Sensor assy? Anyone taken a gauss reading for the two rotors? Quite interested to try one of these

Quick update for Reedy Race. Was able to run myself at NorCal Hobbies yesterday. With only a few runs on the track we made good progress on gearing and most important timing settings.
I would like to suggest to racers that FULL TIMING is not always the optimum for speed. This was again proved yesterday and allowed a couple of the racers to reduce fade and have there best times.
Will be at the track during Reedy to assist all the SchuurSpeed racers and anyone that would like help no matter what motor.
Got to meet some of you who have support SchuurSpeed too yesterday RDOYLE being one.
