great example sohlman, very helpful info.

Default Which servo's should I purchase for throttle and steering?

Hey people I am new to this forum and I must say it has been very informative.
I hope someone can help point me into the right direction as to which servo's would be best for throttle and steering? I had these brands in mind, Futaba, JR and KO Propo. If ya'llz can help with any suggestions and or recommendations it would be very helpful to me. By the way I am looking for high quality servo's. Thanks in advance!

JT

Welcome JT.

The MRX series was designed with Sanwa/Airtronics in mind, but any of those brands will work. And the Mugen kits have adapters for them all.

Big fan of the new line of brushless servos from Futaba

BLS351 Brushless Digital High-Torque Servo for 1/8th

BLS451 Brushless Digital High-Torque Servo for 1/10th

Thumbs up

These BL Futaba's look good but their support sucks

http://www.redrc.net/2007/06/futaba-...bls451-servos/

I was leaning more towards either of the two brands JR and Airtronics for 1/8th scale. I could get JR's new Z9100S (high speed) for steering and throttle due to its fast speed and high torque specs plus a 3-year warranty.

http://www.jrradios.com/Search/Defau...gital_standard

OR Airtronics new 94362Z (speed) and 94361Z (torque), both of which have the same speed specs and different torque.

http://www.airtronics.net/specs/atxservospecs.pdf

Hmm... so many new servo's to choose from... my question is what exactly am I looking for when it comes to the steering and throttle reaction in my mrx-4x? I mean, do I want more torque for throttle since it will control my braking and faster speed for steering for quick reflexes??

Would really appreciate more info from you guys, thanks!
Please, elaborate a bit more

Hey Sohlman, your avatar looks like a 1/8 scale racing body with sick artwork?! I think its dope! I currently have a Shadow body that needs painting and I would like mine looking something like that too! Mind, letting me know who brushed that up for you and can you please send me that full picture of your avatar or post up on the boards?? Right on if you can.

Default gear ratio

Can someone tell me which combination produces more speed on the MRX4
17/20-49/46(stock) or 16/19-48/45. Or is there another combination that works best? I know the smaller the gear the faster it turns,but is it better to go down on the spur or up on the 1st and 2nd?
Thanks, Ken!

Hey JT, J-Go Paintz is the one with the skills. I'm not sure if he's taking any new customers, he's been booked for over a year now. And thanks.

Just repeating some of the help that one of our local Mugen Factory Team Drivers (Terry Brown) shared with me when I asked him the same question. It will depend on the type of track that you are running. Here in Houston, TX we have a track with a lot of tight turns and need a good jump out of the corners. He recommended running 16/50- 20/46 (Hot Engine) or 19/45 (Stock engine). On the other hand in Dallas, TX they have a faster track with more sweeping turns and there he recommended running 17/49 - 21/46 for more top end. I have stuck with his guidence and it has proven valuable. I would suggest talking to some of your local fast guys and get their input for your track.

If you want higher speed run the biggest pinion with the smallest spur on second. Same applies to first gear but you will lose the quick acceleration. If you are just bashing, go for broke and run 18/48 and 21/44

Hi JT, you want more torque for the steering. I use the 9550 Futaba servo on the throttle because it is a little bit lighter. Plenty of speed for the throttle but not enough torque for a 1/8th scale steering servo.

Cool. Appreciate that valuable info., because I just bought an Airtronics 94362Z (speed) which will be used for throttle! NOW I need to find a good deal on the 94361Z (torque) for steering (hoping I could win it cheap off ebay).

I heard good news about these servos from the vets over at the RAMS club in Santa Clara...I just hope that they will keep centered throughout their life.
