I've book marked this thread so in 4 years I can come back and bump it when the MRT clones start having problems after a MyLaps update.

Nothing in RC that you spend $100 on will last you 10+ years, it's a small investment to make considering what we spend on kits, radios and servos.

So you don't own an airtronics 94357?

The answer to that is simple: multiple transponders with the same number make it easier for a racer with more than one car.

I race at a club that runs lots of classes. Now that I am getting older I only run 5 classes a day (we only one qualifier before the main). In the past I have run as many as 7 classes in a day when we had 23 heats per round. For the past 3 years I have only had to remember two numbers for all those cars. That, and only that, is the reason I owned MRT transponders.

When our club upgraded to RC4 I sent my 9 MRT transponders in to get 9 pure RC4s. I picked out two numbers out of those 9 that were easy to remember, and got 3 (soon to be 6) CarID transponders. I sold 5, and will soon sell the remaining two of the 7 who's numbers I didn't "like." I sold them for $88 (the lowest price I found anwhere else for brand new ones) each, paying 92.50 (shipped) for the CarID transponders. I feel the $4.50 premium to get the CarIDs after selling the other RC4s is worth it to me to have less numbers to remember.

If that's hard for you to understand, maybe it is because you have a photographic memory.

If AMB had offered multiple transponders with the same number before MRT did, I would not have bought the MRTs. MRT offered a service AMB refused to offer at that time.

Whats the deal with the trade-in? Why would i send in a perfectly good AMB plus extra cash to get a clone?

People with "perfectly good" AMBs might not want to do this, but if you had one that has become unusable with frayed wires or the like, it might be a good thing to do.

Most people (not everybody) have smart phones or simple flip phones. You can store your transponder numbers in your phone. Very simple and easy, and don't have to remember. There are app's for smart phones to store your setups and those also have areas to store your PT numbers.

I did have some MRT transponders, but no longer have them. I sent them in for RC4's. I will not buy MRT anymore. AMB is doing everything they can to protect their investment, and I really don't want to go threw the hassle of this happening to me again.

Does your club track not keep your numbers in their system? Don't get me wrong, I get a simplified number setup would be less hassle no doubt. But I run at a lot of tracks with multiple cars, other than the first time at a given track the numbers are rarely needed. For when they are I keep them in my phone too like Jimmy mentioned.

This thread is mainly about updating MRT transponders that won't reliably work with the new AMB decoder track system, to a newer MRT that will.

I agree there is little need to send in a perfectly good AMB, as those still work on all decoders. Well at least for now, some are concerned about future AMB upgrades, and might take the opportunity to update at reduced cost, just in case. Or perhaps for damage like ta man mentioned.

With only two primary numbers I did need to worry about a phone as a crutch.

Yes the track does, It was still easier for me to have, for the most part, only two numbers (I have a few other non-cloned AMBs for certain cars).

Funny story:

For years, a guy named Wayne handled the computer at our track. 3 years ago he help start another track and is race director there. I took over the computer duties at my track and since then have never had to fill out a reg form for myself because I just entered the stuff in the computer directly.

Recently I went to his track for a race. Since it was so long since I had to fill out a form for myself, I neglected to put my name on it. But Wayne recognized that the entry sheet was mine by the transponder numbers on it.

Has anyone bought one of the new MRT transponders yet? It's been a few months since the original post, is anyone using them?

I know MRT isn't doing themselves any favors by not advertising this update more.

Yup lots in the uk have them, with no problems at all, I have 7 all with the same number and they all do something you with rc4 and cloned mylaps carnt do, they work on any system rc2/3/4, I can replace the wires and send them for repair. Mylaps don't do either of those.
As their sidnal is near identical , mylaps will need to wipe out their own bug to block mrt.

This is why I bought an mrt. They will fix my transponder. I have 2 amb's that the wires need fixed and one doesn't work and the other one misses so I can't really say it works. So there's $200 down the drain and I can't use them. So, I bought an mrt bc it was cheaper and it's worked this whole time until amb changed their system. So my perfectly working mrt now doesn't work. So, I'll be sending in my transponders soon and get new Mrt's now.

Thanks,

Stormer Hobbies has the new transponders listed on their site (not in stock yet), does anyone know other places that are going to sell them in the US?

Yup unique alright, in the fact they will only work on rc4
I have 8 MRT pts with the same number, of which I solely own. Which will happily work on all amb systems.....far cheaper than 8 amb/mylaps would cost me that I could only use on rc4

Looks like the new MRT (ns) transponders showed up today!
