I've ask that too... and the answer is no.
the HRS will only work with HRS modules and HRS receivers.

I have used KO analog servos with Spektrum without any issues, but I haven't used KO Digitals with it. I just know I have used the 9000S and 8800S without any issues.

It's not really a "Spektrum or LRP" issue. It's a BEC issue. I have had similar issues with Tekin ESC's too. Same fix takes care of it though; just add on a cap, Voltage Protector, or both. Although, when I installed the SR3500 instead of the SR3000 with my Tekins, I didn't have to use the voltage protector any longer.

The only way to have the HRS functionality is to have the HRS receiver and module. The HRS Module will not work with the Origional SR3000, SR3001 Pro Series, or the SR3500 Micro receiver, only the HRS receiver.

i will try that. can i use a novak capacitor because i cant get an lrp. novak says 4700uf should be enough. also one more question. with the ko mars r radio and helios both radios being high response can i use the new 3500 reciever or do i have to get another 3001 standard pro series reciever? thanx rcgaryk i appreciate all the help.

I just want to thank the good folks at Horizon... I sent them my Spektrum module for my M8 a couple weeks ago. In the package, I left a letter stating that my 2 year old son spun the antenna around until it eventually broke off the circuit board. I tried to fix it myself and performed the "Spektrum Mod" to the M8... but, it didn't work.

This afternoon I received a package from Horizon with my module with a new antenna, a new case, and the updated software.

THANK YOU HORIZON!!!!

I actually ended up using that same Novak Cap myself. Should be fine.

The KO HSR system is completely independent from Spektrum. You can actually combine either the Standard or Pro Series Module with any Standard or Pro Series Receiver, Or the Micro. The only thing you can't do is use the HRS Module and receivers designed for the 3PK with each other.

Gary is there a bundle available for the KO radios? Like the module and two or three micro receivers?

Not at this time Ray. Best bet..go with the SPM1013 which gets you the module and 1 SR3100 Standard size Pro Series receiver, then just add the SPM1210 SR3500 receivers as need be. That's how I'd do it, 'cause that's how I roll

Well I finally took the plunge and bought the spektrum pro kit last weekend along with 2 micro receivers. Put the first micro receiver in my T2 last week and it worked perfect...No problems at all!! This week I put the 2nd micro receiver in a 12th scale and it would not go into "bind" mode at all...Tried for 30 minutes. So I took out the new never used standard size Pro receiver and put it in the car. Binded up fine. But as soon as I touch the receiver with my finger it cutts off. You can beat the car shake it turn it upside down but if you touch it or put it on the track and move a few feet it cutts off So I borrowed a new pro receive and put it in and it worked fine. So thats 4 receivers to find 2 good ones!! 400.00 and I got half a system that works.

After talking to several other people Ive found out that out of all the other pro systems that have been sold at my track HALF OF THEM DONT WORK!!! So much for QC at Spektrum!!!

The assembly quality of Spektrum products is absolutely abysmal. The idea is great and I think the Pro units have the software issues worked out. They just need to pay more then 5 cents for assembly! I think they are trying to build a 2.4Ghz product using the same design techniques used for 75Mhz - and that just doesn't work.

I also have a Pro system and out of the two micro receivers I bought only one worked.
Once you get all of the parts that don't work replaced you'll like the system - if you can tolerate it that long.

Spektrum/Horizon Hobby are you listening? We want some quality for the prices you charge! The micro receiver sells for 100 dollars and costs less then 10 bucks to make, spend 11 dollars and have receivers built that always work!

Eric, I'll pass this on. Out of the 6-8 Micro's I have, each has bound without a problem. Now, there was one unit I loaned to someone to try that wouldn't bind to his module for some weird reason, but it bound to mine without a problem. I'm not saying you're not having an issue; contrary to the point. Knowing you and that you're one to be maticulous about things, I trust what you're saying. Everyone who I would talk to about this though is at iHobby this weekend and I don't know if they're going to be in the office Monday or not. I'll let you know what I can find out for you.

Just out of curiosity...just running thru things in my mind. The receiver that wouldn't bind you said was in your 1/12th scale. Did you try to bind it with either a receiver pack or with a 6-cell instead of a 4 cell? Everything I have used to this point has been with a 6-cell pack or a 2 cell Lipo. I know people have used the SR3500 with 4-cells, so I don't think that's the issue, just trying to eiminate any possibilities. Also, what servos and ESC's are you using. The more info I can pass on the better. Thanks

I picked up the "pro system" as well this week. Guess what...one micro receiver was fine and the other wouldn't go into the bind mode. All the receiver would do is once you turned on the car the receiver would flash twice then...nothing. The receiver needs to...flash twice, slight pause, then flash quickly untill you turn on the radio to start the bind process. I took it back to my LHS and the replaced it no questions asked. They did state that mine was the third receiver this week that wouldn't go into the bind mode. From what I understand it's the latest batch causing the problems.

Am I going to have a problem with these receivers down the road? I'm going to Cleveland and this is something I don't want to worry about. Once you get the micro receiver to work will you be fine or is anyone having problems with them after a couple of runs. Should I keep my crystal system as a backup?

Hey Gary,

Sonny Brown just emailed me back and said to try it with a receiver pack as well in the 12th scale. Both of the ones that wouldnt bind were in a 12th scale with No receiver pack....but the 3rd one was in the same car and it worked . I am going to try it here in a bit with a receiver pack and also try it in my TC if that doesnt work.

Both the TC and 12th scale have MRT Speedo's and the 12th scale has a 9602 Futaba servo.

Michael Skeen bought 4 of the Micro receivers and only 2 of his worked as well. When you turn them on with the bind plug in it only flashes twice and then goe's out. The one that worked in my TC keep flashing as it supposed to until it was done binding with the radio and has worked perfect for 2 weeks now.

Thanks for the help.

Of all the ones I have seen with problems so far at the track they have never worked out of the package....No one has had problems out of them as long as they work right off the bat.

Ive already sold all my entire crystal system after the first week so now I am down to one receiver for 2 cars next weekend as I doubt I will get a replacement for the Halloween Classic next weekend IF mine dont start working.

EA

Sonny's the 4-cell expert, good to know he's in the loop on this. Like I say, I'll pass this on.

FYI...I'm using them both in TC. GTX speedos. Tried to bind with FULL charge on battery packs. Flash twice then...NOTHING.
