RE: DA 100 - starting drill?
typically - warm restarts are quicker with a lower throttle (idle setting) and/or a slightly richer idle setting - any engine - my ZDZ stuff afer setting between flights - takes a lazy flop and that's it.
unless you overheat an engine or it is already smoked - most any gasser will do the same - except for the old magneto thingys
hot restarts tho -a different thing - you flop thru a half dozen NO CHOKE attempts then they start - has to do with heat .
