a 50-60cc motor is just not what your target market is likely to choose. IF you want to go gas why not use a da-35 or a vv40. Otherwise where does this plane really fit? A big fuse doesn't necessarily mean it needs a ton more power. I would be a lot more concerned about trying to achieve a light build for initial testing.
I favored an electric power system just because you can confidently huck the plane without any delay once it is built.
Put a 50cc gasser in there and I feel you are really disconnecting with your target market.
I dont think I am..Have you ever personally run a 12S setup? Your a seasoned guy who flys 35cc all the time. IMO flying 12S is cool if you have a ton of packs and an incredible charger. That charger alone will cost $$$ too. Heck, I dont know of too many entry level pilots running 12 S setups.. The packs alone cost as much as a gas motor.
I say to fly on a Sunday you need 6 to eight 3500-4500 6S packs.. A cheap ole junk 3500 6S will cost you $65 to $70 bucks each. Do the math.. A 35cc Motrolfly motor MOTROLFLY DM-4330 is $225 plus shipping. Now a 12S ESC $120 ish.. Electric cost as much as gas if not more IMO..
A DA 35 vs a DA 50 isnt that much difference in weight. I personally like planes with Much power.. I will consider all options. Ill fly it with a 35cc gas, electric, and a 50cc and a 60 cc. This is a test bed. Hell it doesn't have a cowl yet.. I will beat the snot out of this plane, then ill build another that's better, then do it again..
The kit comes with all the stuff for gas or electric setups. DA-5- $549, DA 35= $449.. Wither way,, its going to cost some $$$ to outfit a 3D plane this size...
