Hey guys, Should be getting my RC10B4.1 today in the mail. Had a question about gearing,. What is a good size pinion to start off with using a 13.5t (Reedy 300kv) motor keeping the stock spur gear on it ?

24/81 is where ThunderbirdJunkie would start with the RTR Reedy 3300kv motor for gearing

13.5 racing usually requires a smaller spur gear to obtain good speeds...if the car comes with a smaller spur, use it with a 28 or 29 pinion.

Bill,

You have any part numbers for those "K" springs you are running with that new +8 setup? Was looking for the springs and didn't really find what I thought were the right ones. Also you still using the stock rear u brace or the one you had modded for the C-hubs. Just picked up the +8 and was looking to get a good starting set up on it and every time I've seen you at Traction, you've been preety fast. Thanks for any help

I ran 75/30 with some boost when I was running a 13.5 for a while. Motor never saw temps higher than 150 either.

Can someone tell me the difference between the c and a hubs? I'm not familiar with the terminology.

For anyone looking for info with gearing a 13.5 / 17.5 with boost:

The new Reedy Sonic motors are amazing...this past weekend at the SIGP I ran both boosted 13.5 and 17.5 classes utilizing the new Reedy Sonic stock motors and LRP Stock Spec V2 Speedo in my B4.1. In 13.5 I was geared 72/29 and speedo profile of 3/7/7/4. With 17.5 I was geared 72/34 with an identical speedo profile. Both motors made great power and were incredibly smooth to drive and both came off the track consistently around the 135 degree mark after 6 minute qualifiers. We ran a 10 minute main event in both classes and with deciding to not change my gearing I was amazed that both motors came off the track at 135 degrees after the 10 minute main. I ended up taking the TQ and 1st in 17.5 and a 5th in 13.5 with this Reedy/LRP combo taking 3 out of the top 5 spots including the win. If you guys have any questions please feel free to post them or visit the Reedy thread.

Great job this weekend Matt!

thanks for posting this, i am looking for new moters and ill try out these i think novak is really good but i feel like some moters are faster with the same gearing....idk may just be me

Thanks Chris!

hey guys for the b4.1

whats a good choice system...from tekin, from castle, from novak and from hobbypartz?

thx!

Can't go wrong with a LRP or Tekin speedo. Motor? I hear the new Trinity/Epic Duos and Revtechs are awesome. My Ballistic Novaks have been solid, but I'm game for trying out a new motor. I may pick up a 17.5 Revtech for my SC10. I think it's more important to have a better motor for spec classes than open mod classes.
