It all depends, for example some electrics are having problems if it is hot or windy, that happened in the Nats and on the Europeans(ongoing) on a windy day, one of the spanish pilots ran out of battery missing the las two manouvers on one P round, most will think he does not know how to fly, but he is in the semi finals, so can't be bad, but the important detail is any electric is good enough to fly any schedulle, it is just a matter of battery capacity for the intended flight agains the airplane weight to be legal. As any airplane over 11Lbs can't be considered competitive.

I am very happy with both electric an YS, but preffer YS, extremely reliable engine and there is nothing that compares to the power of the 175 in my opninion, but there is a opinion for everyone, including those who do not compete.

It will be interesting to see what happens today and tomorrow in the EC, I am sure for South Africa there will be new batteries as they are struggling now in certain conditions, and not knowing if a pilot can finish the new Unknowns in a hot/windy day cannot be good, but again, it depends on many factors, and I ran out ouf batteries only once, and not shure why yet(but I was setting the airplane), but so far, three flame outs and one single mechanical problem in five years is pretty good for my YS's.

Another example is CPLR said F3A is to be flown with IC engines, as well as Mayr is doing the change, heard of some top pilots who think about going YS again, but time will tell.
