Sadly, no. See:

As long as Brad doesn't want to cruise long distances or climb to great
heights, but is just looking for a couple thousand feet to get away from
a low cost launch, it should be practical in the Apis. The electric
motor would easily avoid the problems with two-stroke motor vibration
that Lange is working to overcome, while offering even simpler, more
reliable operation, all with no loss of power at high density locations.
I'll bet those claims sound familiar!
