My champ was in permanent storage because the gears were messed up so i decided to take a chance and get the high performance micro motor SA8523/N with the wide mount gear box. It was here super fast in a couple days and It only took a couple minutes to install. Like the blink of an eye, i was in the air again! This time with a lot more power!!”i like more power”The original motor had 30g of thrust and this one has 44g and it is very noticeable. I also like it because its a direct easy install and it gives the champ almost unlimited vertical and many more acrobatics. Thanks Stevens Aeromodel, I don’t leave many good reviews these days but this one deserves it!!
