I've just had a good look around the store pages and even downloaded some plans yet I can't seem to find some info regarding which batteries FT recommend for each of their FT Power Packs? I'm sure it's there somewhere but I can't see it right now. I'm specifically looking at the FT Mini Mustang with Power Pack A but it would be handy to be able to know what batteries are recommended for each Power Pack for future reference.
Ignore Ft recommended battery packs, they list crazy small packs and the extra weight of a bigger pack is desperately needed on many of their planes.
Take the Ft cub for example, they suggest a 1300mah 3s, are you kidding??!!
The smallest I fly my cubs on is a 2700mah and that give the perfect weight in my opinion, mine comes in at 890g on a 2700, mine have lots of extra electronics and I also use metal gear servos adding to the weight.
The 2700 also has loads more capacity than that tiny 1300 which won't balance the plane ether but I regularly have my cubs in the air on 4000 and 4200mah 3s packs and an all up weight of 1.1kg although I don't recommend that to new flyers and I have to land fast when that heavy on a stock wing but a storch wing on a cub allows super slow landings even when that heavy!
My point is that Ft specs are useless, forget the power packs, forget the recommended batterys, source your electronics elsewhere for much less and get better gear (metal gear servos are a must) and you will be surprised at just how well they fly well over ft specified weights, those are only good for absolutely zero wind!
