GarlicBronco's H10 Optic Build Thread

[GarlicBronco]

I have done some searching in this group and others. I am new to crawlers but not new to RC. I am gathering parts for an Optic build. I am learning that there is more to servos in these things than in my other stuff (b7/sct410 2.0 ect). School me on them. Are we not connecting right to the receiver like in other builds? There are servos with their own battery or on a splitter? I know opinions are like..... well you know the saying every one has one. What are some of the most used ones so that i can do proper research on them. If it matters i plan on using the HW 2-1 fusion 2300 and a fly sky receiver with my nb4+. The servo is really the only thing I've had hang ups on picking out so far.


Thanks in advance for the time/info.

The reason for not running straight from the rx is it is dependent on the bec from your esc, some of which are limited to 5v and low amps so it does not make for a powerful servo. Even the esc with higher voltage max out at 8.4v (that I have seen).

So you can run a direct power servo straight off the battery which if you are using 3s or 4s batteries can easily give you more power. Though I have found direct power servos are more expensive so...

There are some powerful servos that are powered normally through the rx such as Hi-Tech servos, though I have not had personal experience with them (yet)

Personally, I like Holmes hobbies for high end direct power and the blue ds3235pro off Amazon for cheaper builds that run off Bec/rx power.

My nsdrc direct power servos are nice and smooth when they work but are not as powerful and I have had poor customer service and the gears lose teeth and leave me stranded on drives too many times to personally recommend them. Others on here have had better luck.

AGFrc servos are a major supplier for many popular makers and can buy direct or through Amazon (they have an official store). There is not much difference between what you put in your race trucks; you are just looking for more stall torque, and still a quick speed. I have Savox, Holmes, AGFrc, NDSRC, Reefs, cheapie blue and red Amazon specials. They all have their places, you kinda pay for what you get. Just remember nothing lasts for ever even when treated well.
