RE: Extreme Flight RC 104 inch 100cc Yak-54 sneak peek
Ya it's pretty hard to get a controlled test. Def some interesting info. The extension length drop is also interesting although there is no way around that really.
Personally I am happy with the 5955s.. I can KE-Loop my 33%er on one in the tail nps... I will be adding a second though... but really just for useable tail weight.
