i had a gforce motor on my 57" 330sc and loved it. also also have a gforce motor on a 51" slick and a few others and have had great longer term durability and great power. super smooth too. ive had good luck with them.
I've had Gforce on my Airfoilz and Edge 41", both motor started running weaker and weaker. The 75g GForce pulled 28A & 41oz thrust with APC 11x5.5 while the similar size Infinite pulled 38A and 59oz of thrust. The diff is like day and night (very close kv).
I am using the Infinite A5020-250 (440g or ~ 15.5 oz, rated at 1600W) with APC 20x10 on my SC 72, ~ 190 W/lb and still flying good as new (motor barely warm on my setup, ~ 1900W). Did you get the smaller size motor (or not the best kv) for the Slick 70"?
I am also using Infinite A3025-770 kv (182g, rated at 500w) on my Slick 51" and SC 57". Motor slightly warm after 10 mins flight (~850w at WOT). The rating is very conservative.
I've flown Hacker/ Motrolfly. I wouldn't replace them if the Infinite motors were bad.
I am not complaining about GForce and Turnigy, but all mine are dead now. They are making too much noise and too little power.
