I was wondering whats a good servo that you guys are using? Also, what kind of tires are you going with. My local track uses Sorex but not sure what to get. I see a lot of Sorex xxR...what does that mean? My guess was it has something to do with the heat of the track related to the tire.
So if you guys could point me in the right direction and just let me know what you think about what I have so far and if there is anything else I need I would appreciate it. Thanks in advance.
Ha-ha! For once good advice found a good home. Your car and electronics are indeed top of the tops. Perhaps the radio will need upgrading but that's in the distant future for now.
About the servo, everybody has their own preference again.
The KO servo recommended above is probably a good one to start with. There are others of better specs but have their own downsides.
I personally use only the JR 9100 series which is faster than the KO (it's actually the fastest servo on the market), has more torque (the highest torque for the speed) and is all metal geared, ball raced, coreless motor. It really has all the bells and whistles.
Downside is that is a hairwidth wider than a standard servo. This is not a problem as most cars have some adjustment allowed for different size servos.
Another downside is that the JR servo is quite heavy and right now I can say I would like a little less weight in my car as regulations allow a lower race-ready car weight than in the past. If I balance my car left to right for instance, I need to add weight to the battery side until I am above the legal weight by a little margin, because of the heavy servo. With a smaller, ligther servo, I would be spot on, but then again, I like it's reaction speed and categorically positive control of my steering.
Talk about servo speed, when choosing the servo, make sure your radio can handle it. I have discovered to my surprise some time ago that the radio I was using (a first gen DX3, DSM1) was too slow to make use ofsuch a fast servo. Not sure about the DX3R, but I don't think you need to worry about it with a .1s servo. If you do decide for a faster servo, ask around. I switched to a KO Helios radio and only then realised how capable my servo was.
All this comes at a price though (in Australia, these servos cost half the price of your car).
However, it is very likely that you'll never need to buy another servo. My oldest is pushing five years of racing, crashes and all with no issues at all. Over that timespan, the price becomes more than acceptable.
