Another question or two for you GT Pros

Post by Ty89m »

Were they always this fussy about the steering servo size? I planned to use Futaba S-U305 servos all around, but they're a bit too wide and the servo mounts don't line up with the chassis holes. I'm hoping they'll fit better on some of the other AE re-release kits I've accumulated, but I'm guessing it'll be the same outcome. Fortunately I had some spare Hitecs that fit a bit better, but I'd have preferred to run my Futaba set. You can even see the steering servo mounts in the promotional shots angled outwards due to their servo being too wide for the chassis holes, so it makes me wonder what dimensions they had in mind when they drilled the chassis. I'm temped to try the J.Concepts mount in the hopes it would work better with my Futaba servos, but I'm guessing I'll run into the same issue. Beyond that, I'm making progress (first nitro)!

Lastly, how many of you bother with the rubber grommets on 1/10 scale nitro? They're hard mounted at the moment, but I'm considering running them once I get longer 4-40 screws (the grommets are so thick they leave little thread to engage in the mounts). You can't run the included eyelets as the screws are too large, but I'm guessing the rubber alone would be helpful to dampen vibrations.

I find on a fair amount of cars/trucks, you have to barely thread servo mounts at all 4 corners first, and then tighten them up from there. If you lock any one or two corners down the other screws won't fit.

On all of my RC10's, I loose mount the servos first. It isn't uncommon for them to be a little out of alignment.

If you are trying to use screws or washers that locate the servo, they will limit the amount of play that you have to work with.

I'm using the kit supplied washers, and they don't appear to limit how close the screws can get to the body of the servo (getting the mounts as close to each side as possible to minimize width), though it may be worth trying smaller diameter washers. I think a lot of it comes down to the dimensions of these particular Futaba servos; they're standard size, but the actual locating holes are wider than many of my others. I am able to get the Futaba working for steering if I run the rubber grommets, as that allows some wiggle room for the screws to angle a bit without putting a tone of pressure on the plastic tabs. The mounts are very clearly angled outwards doing it this way, but it is serviceable.
