the chance of a PT-number-clash is very slim. And if it does, it's almost certain that it will be with someone with another MRT-pt, as MRT ONLY uses the PT-numers THEY possess.
You CANNOT clash with someone else who has an AMB-PT!!
So it would not be difficult to agree with the other person on who of the two will change his pt-number with a simple click on a button.
Other advantage: The MRT-pt uses less volt. It sometimes happens that at the end of a heat, the voltage drops when you open up the throttle 100% en de ESC demands a lot of Amps.
In such a case, it could happen that the PT does not have enough Voltage left and will miss a lap when it passes the antenna.
(when a AMB- or MRT-PT passes the antenna under the track, it registers the antenna (which sends out a signal) and in return answers with his PT-code. When not enough voltage, the PT is not capable to emit his pt-code)
As the MRT-pt runs on less voltage, the chance of missing a lap is strongly reduced.
Also, the MRT is smaller and can be much more easely repared in case of damage on the PT-casing or the wire.
I own both an AMB-pt and an MRT-pt (which has the cloned number from the AMB-pt ... so both with the same pt-code).
The AMB-pt is a very nice product. Technically well build, good technology.
But the MRT-pt is no less AND cheaper!
Ever heard of a certain Marc Rheinard ?
He runs an MRT-pt also. And those guys don't take any risks.
About being out of stock.
MRT just can't keep up with demand
Best is to give them a ring, in the morning. You'll get some direct answers.
