Experience w/ Dasmikro Receivers for KO?
 

I posted this in the KO radio thread but has anyone tried the Dasmikro receivers with the EX-2 (or similar KO transmitters) and if so would you recommend them? Thanks

I have experience with them, very reliable and clean signals, however they use lower quality components, I had a write up on RCFiles but that forum is long gone. They use steel pins which are not gold plated and the frame rate is slower but not slow enough that I could detect the difference.



I'm just pulling numbers out of the air because I can't reference the thread where I recorded my readings, but I want to say that the KO branded Rx was around 5ms and Dasmikro was closer to 10ms, where the SPEKTRUM DX5 Pro is 11ms to give some reference.



Bottom line is Dasmikro is lower quality, but they are good enough for club racing ;)

I wonder how a receiver can determine the framerate. That is a steady number made by the transmitter regarding the used transmission mode.
And the transmission mode is an issue with 3rd party receivers. Many 3rd party Futaba receivers only support S-FHSS which lowers the performance. Dasmikro has a T-FHSS receiver that boosts up the performance but they have no SR mode supporting receiver.

Regarding the "steel" pins you mean the servo connectors? I have seen plenty of them, they are not steel and do not oxidize that fast

I used a PPM meter to measure the Hz from each Rx where the quality of the Rx is what I personally observed as the limiting factor. Not only have I seen this with Dasmikro Rx's compared to KO Propo Rx's paried to the same Tx, I also saw this with various Rx's of different model versions of the same brand of Rx when I was taking PPM readings with other brands like Radiolink, FlySky, Spektrum and Futaba


No need to be a clown over the steel pins comment, perhaps they are made of tin (no specs provided by Dasmikro), either way it's semantics so go clown somewhere else.

Why so rude?

Again, the receiver does not determine the framerate than only its needed transmission protocol and to my knowledge with KO the transmission protocol is set manually.

As I did explain most 3rd party Futaba receivers only support the slower S-FHSS protocol, does that make them a bad quality? No, they are just made for that and use the same framerate as any Futaba S-FHSS receiver.

Regarding the pins: Board to board Pin header plating&materials | Products | GradConn
They are still brass pins nickel plated giving the idea they are steel pins. Steel is hard to solder, thats why I doubt your statement unless you did put an XRF gun on it.

I can assure this is a bad assumption to make. I have a tool to measure the frame rates when swapping Rx's of the same brand of Tx which debunks your theory. I have even seen cases where the same model of Rx were ever so slightly different. While I agree that the Tx may have a "Max Frame Rate" that it can support, it's still going to be limited to the quality of the Rx which I have personally observed as the variable across the many brands I listed above.

Thanks for the feedback!! I decided to try the Dasmikro FHSS KO alternative receivers.

Yes?
Then tell me how the receiver is telling the transmitter what framerate to use? The receiver can not read the servo's if they are analog type or digital with a 200Hz, 333Hz or a higher limit.

You are misinterpreting what I am saying. While many high end Tx's will give you the ability to adjust the frame rate settings, there is no guarantee that is the actual frame rate without using PPM monitor to measure the actual frame rate from the Rx. The quality of the components in a given Rx will be limited to what the frame rate actually measures where the Rx is the limiting variable. I already explained this in my very first response in this thread comparing KO Propo branded Rx's with Dasmikro... the Tx is going to try to get the best frame rate, but when it binds with the Rx, it will be limited to whatever frame rate the Rx can support, simple as that.

Regarding your original question, I have been using a few of the Dasmikro receivers with a KO EX10 Euros for 3 years or so, and they work perfectly fine. I cannot tell any difference between them and any of my legit KO ones.

Same here - my son club-races a variety of original and daskmikro rx'es on his cars and he cannot tell the difference. I'm sure there is one, but we don't feel it.
