RE: What effects or controls spool up time?
Sorry to disagree guys, but that accel. is not normal of the newer turbines in this class. 6-7 seconds is not normal (maybe for this brand, that I am not sure and I would error on the side of booster and say that this turbine has more potential to it.)
It could be a setting besides the accel. that can be adjusted. However I am not familar enough with the booster menu strut. to know.
However, when I get back in town I will post a picture of my rabbit accel time. I know this is a diff. turbine. However the booster 90 is advertised fastest in it's class (19lb. I assume) and as the video will show at the same alt. and similar temp my spool up time setup like his is will be right in the 3 second range.
I don't expect the booster 90 to accomplish this. However i would expect it to be less then 5 seconds and closer to 4. From what luckyflyer told me, the rep told him that the owner or president told him 3.4 seconds.
I am sure this turbine can be made to accel. faster. But when someone buys a turbine because it's advertised fastest in it's class, and gets one that has a 6-7 sec. accel. time then the customer is not happy.
Chad, please explain your statement "The evoJet software measures airflow through the engine 20 times per second". I assume you meant that it monitors temp and rpm's 20 times a second?
I hope to get the video up by Monday sometime if not sooner
