RJ Gritter flew a prototype with the Hacker Q80, again power was great, but flight times were short and for the 2011 King 50 contest he switched to a DA-60. For me, and this is just my personal preference, I prefer a gas engine for this size plane. It is a lot of work to maintain several sets of 12S battereis and all the support equipment requred to fly as much as I like to fly when I go to the field. I feel that I am just getting warmed up when it is time to land with the electric setup. I believe it won't be long until the battery technology progresses to the point that 10-12 minute flights are the norm and then I will reconsider my position.
yes, flighttime is an issue. i cant fly gas at my flying field so i got to deal with it.
so the 22 inch prop felt enough for such a big plane?
i plan to go with a 25 inch prop. is it too big?
whats the ideal prop?
