Guys! F3A is a competition about flying, not motors. The propulsion is simply a means to an end, when the dust settles each one of use needs to use whatever propulsion setup we feel makes us the most competitive based on budget, experience, time, schedule, skill etc. etc. etc.

There is no right or wrong, it is simply a choice. Getting into an argument or disliking someone because what someone chooses to fly is rather silly.
