Where to send to get updated? Any place in the states?

Need to send them to MRT only ones that deal with them
Look for them on face book or their website

mine took about 3 weeks turnaround and Terry is real easy to deal with

Thx Tim

They have to go back to MRT in the UK for the upgrade. I had mine done and it works great.

Is an updated needed to get them to work with the latest mylaps firmware update? I purchased an MRT about 8 months ago and it’s still working great at my local tracks s they haven’t (and said they won’t) installed the update.

Once your track updates the software the MRT will no longer work unless you send it in for the upgrade.

Cool. So they are still capable of working once upgraded as well. Could you post a link so that everyone with MRT transponders can get the info to send theirs in if needed?

I do not have a lnk as I sent my PTX transponder to a member of another club close by who took it upon himself to do a bulk shipment to MRT in the UK on our behalf. You might try contacting MRT through their FB pages for details. Cost wasn't too bad around $25

Thanks, thats the info I needed

Rumor has it that MyLaps is doing another update so that the MRT transponders wont work again. Anyone else hear this?

If you do the latest decoder update RC4.5 it kills MRT's and Mylaps older models.

I have a pinned post in the radio and electronics section regarding the update. I spoke with a guy over at mylaps and the update is only needed to make use of drone racing transponders, and is not a forced update. More than likely your track knows not to update.

Here is a thread discussing this very same subject.
MRT RC4 Compatable pt news
I think Terry has a thread on RCTECH somewhere but have yet to find it again.
I sent in mine a couple of years ago and paid for the upgrade. I also bought 2 of the new model MRT transponders at a discount when upgrading my old one. They all work great!
