Futaba radio, and mixed servo's

[nitro_dign]

I have a old Futaba radio model is t2phka. The servo's are 1=futaba 1= i dont know the brand. It all rests in a kyosho inferno. I am wanting to change out the servo's for ones that have better torque, and maybe quicker reaction. If someone could help on recomendations, I would greatly appreciate it. Thanks again to everyone, you ROCK !!!

What are you putting them in? I like the Hitec TG's a lot but they may be overkill for your application.

Yeah, which inferno? The kyosho inferno name is like HPI's RS4 naming convention. It is the platform for both 1/10 on and off road vehicles.

Which (if any) of these is it?

Sorry guys, I did not know that. It is a Kyosho Inferno 7.5. Has a O.S. vzb (non v-spec) mill on it. Good buggy so far, I just noticed that the steering servo seems a little weak, thats all. Thanks again for the suggestions!!

Hitec 5955TG for steering and 5996TG for throttle/brake. Hitec's warranty is hard to beat should you ever have to use it and with 333 in/oz slinging your wheels around you'll never have to worry about enough torque. I used JR9000T and JR8800T and JR8800S and they weren't as good and actually ended up having to send all of them in for warranty, got new one's back and sold them. I have never ever had any luck with Airtronics nor do I really know anyone that has.

remember to chk the wiring of the servos when you replace them I thinks its Futaba that has diff. polarity in their receiver?

I never had issues using futaba, JR, hitec, airtronics all on the same receiver. I've had to cut little plastic flashings off the plugs to get them to plug in, but other than that, no issues.

It's Airtronics that uses reverse polarity on some of their receivers and servos

Isn't it just some of their old stuff? Like 10+ years old?

 

[jetmechG550]

No, some of the newer stuff has it and it's tagged, you need adapters.

Hey guys, I did some looking, and I found these. Can anyone tell me anything about them? Are they good? worth the money ? etc. Thanks again for everything!!

Too weak. For a 1/8 scale buggy, you should have at least 130oz/inch for torque on steering. Preferably more. The ones you listed only have 76.37oz/inch of torque. Unless your truck requires two for steering, I'd definitely go for something stronger.

OK, some other ones I saw that might work, but I dont know how to convert kg into ounces.

you can use an online conversion to convert from Kg to oz/in.

http://www.onlineconversion.com/torque.htm

At 6v it would be 208 oz/in
at 4.8v it would be 180 oz/in

Hope this helps.

 

[olds97_lss]

That should be plenty for what you want. If you get one of those and they hold up for a while, let us know! At $20, if it lasts longer than a few bash sessions, it wouldn't be bad to have one laying on the shelf for backup.
