John,
I have placed several orders through Hobby City and have had no issues whatsoever. The turnigy motors I have bought all perform or exceed factory specs and the batteries have been equal to their rated current and capacity.
I just recently bought a Turnigy SK 42-50-650 intended to be used on a large ECL bird (700 sq in) I have designed and am hoping to get airborne this year. It will run on 6S 20C Turnigy 2650's which can be charged at up to 3S. I also bought a Turnigy Accucell 8 which has more functions built into it than most chargers on the market 5 times the price. The motor, (3) battery packs, and charger cost $200. It cost $47 to ship expedited mail. Build quality on theses components are excellent and can you say affordable? The power system is capable of sustaining 1200 watts at rated capacities. That says a lot for a motor that cost $25, and a battery pack which cost $35!!! I have (4) cycles on the packs already and they have performed quite well from the start (bench testing). I look forward to getting them in the air. The Turnigy Li-Poly's are offered in several sizes and cell counts.
Take Care,
Archie Adamisin
