Hmmm, I do agree with both @billdelong and @Darkgenerals at the same time.

I mean we are talking about a $160 servo here so I would expect resolution to be high, and on these higher end servos ($100+) it isn't like we are asking much for our hard-earned money to display full specifications of such premium, high-grade products.

On the other had resolution is indeed determined by the lowest resolution available between the TX, RX, and Servo. Pretty sure 31.5 degree steps per 1 degree of servo movement is impossible for a human hand to achieve on a TX steering wheel lol.

I ran one of their servos for a while and I couldn't tell any difference, my lap times didn't change whether I ran a $120 servo or a $20 servo. There is a point of diminishing return on improved resolution and I believe 8 bit is where it's at, however, I believe you're limited to the lowest resolution between the radio and servo... for example: having a 32 bit servo will be limited to 16 bit if that's all the radio can handle.

Agreed, again that's not the point. I'm using it as a point of comparison and I want to see if Tekin's claims of some superior technology are true.

They make the claim, I expect them to back it up. Majority of tekin fans blindly follow and don't ask questions.

It really is a shame radiopost shut down. 32bit is overkill but damn that's impressive they pushed the envelope so much.

It is sad, kind of like the death of Radio Shack. I always loved their RCs growing up, and I always considered them to be the "turning point" between hobby grade and toy grade RCs. Their RCs were just so much better than anything regular toy companies had to offer. I so wish I could buy the Dark Shadow buggy right now just to have a reminder of what they once were, but every time I have checked online for the past year, it is out of stock. I really doubt they will ever restock it :(.

I don't know, Tekin makes some pretty good stuff, there's a reason why they're arguably one of the top 2 most popular brands of electronics used at the tracks in my area. It's refreshing to me to see them enter into the servo market share, though I am still tapering the classes I run, so who knows, I may eventually start to buy all luxury electronics at some point in the future. If I had enough disposable income, Tekin would be toward the top of my list of brands I would trust.

Same applies here. Tekin is my #1 most trusted brand for ESC's and motors (when used in racing applications at least, bashing is another story), they are also the brand that powers quite a lot of championship-winning cars, so you can't go wrong for sure.

However, I personally can't recommend Tekin's earlier generation RX8 ESC's. While the Gen 3 has been fantastic, I had MULTIPLE Gen 1 and Gen 2 fires, even running low gearing and batteries that were capable of more than 150% of the systems requirements. Gen 2 fires aren't as common, but A LOT of people had Gen 1's going up in smoke.

This makes me want to wait before purchasing one of their servos. If history has taught us anything, its that when a company makes something BRAND NEW, and they aren't experienced with it, it tends to suffer from issues at first. I would wait at least 3 months after release and research long-term usage reviews on the servos before buying.

Once I know that people have been running Tekin servos for a few months without issues, I will consider the purchase alongside my planned ProTek 170SBL. Hopefully someone will compare these two servos as they are in the same price bracket. That T-250 Tekin servo sure looks tasty though.

I dont think you will see issues in the first few months. I have a feeling it will be 1 year and beyond.

I believe Radiopost had early reports of gear failure issues and they were all swept under the rug, they never acknowledged having a design flaw and never released any updates to the design of their gears. Same was the case with their TS401, folks had several concerns with the design and they only released 1 update to their Rx's, nothing was ever fixed on the Tx... and then it was no surprise to see the brand go out of business because they didn't address customer concerns.

I believe Tekin has a good track record of correcting issues in the past, which is why they are still in business and Radiopost isn't.
