Default purging the garbage.... servos first

I am gonna upgrade both my shift and steering servos. After a ton of searching I have decided to go with a full size shift servo in both positions.
(will make a plate)
I have seen the Hitec wp5646 suggested for the steering position, is there any reason it could not be used for the shifter also?

Or, can anyone recommend others that may be more suitable? I'm not opposed to spending a few bucks for quality (within limits...)

I used the 5646WP for steering in my TF2 and used the 5086WP (smaller) for shifting. It definitely has enough torque for shifting (on the fly) but make sure your EPA's are bang on otherwise you will quickly fry the servo. Happened to me the first time.

Thanks, turns out I actually have a HS-5086WP that's NIB. I think it was once gonna be a steering servo for my MERV.
I will give it a shot based on your experience

thanks

What's the diff between an analog and digital servo in terms of how we use them?

Better performance ie; more power, better centering, better motors etc. With the HiTec's you can get their programmer and set the max current, centering, fail safes etc. Mainly used for planks though. I used them in my truck because of their "water-proof'yness".

So the "digital" aspect is that they can be programed and if you are not going to (or need to) do that they operate the same otherwise?

Yup. Just a better quality servo.

FWIW I'm still using the factory shift servo without issues. After swapping to a Futaba radio and receiver that servo has been functioning flawlessly. There's really no need to slap a big, heavy, standard-size servo atop the transmission to actuate the shifting mechanism. The shaft for the shift fork should slide relatively easily, if not you might want split the case and grease the shaft. It doesn't/shouldn't require the torque that a standard servo can provide.

However, I just replaced the factory steering servo with a Savox SA-1283SG. What a massive improvement!!! Sure it was a little pricey, but with 400inch/oz of torque it should easily overcome any grit/binding in the steering rack.

Thanks, I think I have changed my mind on the shifter servo size and will use either a Hitac 5086wp or the more powerful mini 225 that lots have reported using with success. (67 in. oz. Vs. 50 for the 5086 and tther are only 25 bucks)
My steerer works but I was not at all happy with the huuuge amount of slop in the servo output so, it's on my list. Thanks for the recommendation - I do appreciate quality!
