I'm not familiar with the enya 09, but I do have its bigger brother 15IV TV R/C and its really good a freind has the 19 and its also dead reliable. From what I can gather Enya motors are of very high quallity and very good sports motors , buy this I mean they generally have smaller venturies for there size , as a result outright power is slightly down on the competion BUT they throttle well and with the normal sports sized props performance is about the same as most.
They get a vote from me.
