I’ve emailed them with these questions.
So how come they got an STC for the TB20? Don’t ask – I have seen the same with some air filters which were never tried either… I asked him that question.
Their STC recommends different spark plugs which (Unison) look ever so close to the Tempest ones, so prob99 these people did realise the dodgy Champion plugs will damage their ignition coil.
Another reply here:
He did not answer my question about how they managed to get the TB20 on their STC when it is clearly wrong.
So it definitely looks like the TB20 STC is not usable even though, ahem, ahem, it is on their STC
Update on this old topic…
Apparently Electroair showed a D3000 replacement ignition system at Airventure 2016.
So something is happening.
BTW one cannot fit any single mag into the existing hole because the gearing is wrong.
I’ve read on a US site that Electroair are talking about Jan / Feb of 2019 for the four cylinder version and about a year later for the six cylinder version.
Hmmm, this is almost 2 years after the above post
But aren´t all Lycomings equipped with dual magnetos?
Yes, but in some models the two magnetos are in the same unit so you can’t just replace one of them.
This suggests that the single shaft dual mag solution will have its own generator
Electroair Vice President and Chairman Peter Burgher also provided an update on the company’s anticipated supplemental type certificate for a hybrid magneto that will be a direct replacement for four-cylinder Bendix dual magnetos. The RC4000 series will use one electronic ignition with one mechanical ignition. The hybrid magneto uses a high-energy rotor to mechanically create energy that is supplied to individual coils at the cylinder. This allows for 30,000 to 35,000 volts of additional spark energy to be available for ignition.
