We have not shipped any Explorers as none have thus far been completed. We only expect this to happen end of March judging by current progress related to the various contract manufacturers. MGL does final assembly of the parts as they come in. A bit like Boeing's 787. Logistically quite challenging to get this right. Just one minor delay of a single part and everything has to wait.
iEFIS breaks with our tradition as it is time for a fresh start with respect to the various "support boxes". In the main this involves new communications buses, new protocols and new distribution of "work" among the various bits.
iEFIS cannot use any of our current AHRS, compass or RDAC (engine monitoring) units.
iEFIS gets a brand new RDAC called a "RDAC XF", a new AHRS (a version of the SP-7 with some changes) and a new compass (a version of the SP-6 with some changes).
iEFIS does NOT support the COM extender or the I/O extender for the simple reason that it has those two built in as standard.
Current SP-6 and SP-7 units cannot be upgraded by distributors or yourselves. We can upgrade them at the factory but that is only feasible for South Africans due to the high shipping costs and customs hassles.
Current RDAC units cannot be used with the iEFIS.
On the other hand, new SP-6, SP-7 and the new RDAC XF can be used with existing MGL EFIS equipment which remains in production so we have full compatibility here.
SP-4 and SP-5 AHRS cannot be used with iEFIS.
We have a new tactical grade AHRS in the wings called the SP-9 (usable for all systems).
Pricing for iEFIS has not been fixed yet but it will be good. Most Explorers from the first batch have been reserved by various customers. None have asked for the price - I suppose they know that that is not an issue.
We tend to price things quite tight as we have a long supply line - in order to do that we need to know every single cost and that we only know once we have assembled units and can start adding up - anything up to that point is an estimate only.

I do not think he meant sold out as my understanding is they are not yet available. MGL has established a waiting list. There are additional mod's to the existing supporting box's that must also be updated to play with the Explorer units.
