Don't get me wrong...I love my Hirobos (Freya 90 & Sceadu EVO 50), but I am curious if anyone else has had a similar situation.
Keep in mind that this is only the second helicopter I have owned, so I don't claim to be any type of expert.
I purchased the Sceadu EVO 50 ARF. During assembly, I noticed the tail blade holders were very loose (at least much more loose than the ones I assembled on my Freya). But, being the trusting soul that I am, I reasoned that the Hirobo factory must know better than I what is too loose or not? Right!? During the first flight, I noticed the tail was vibrating quite a bit. My initial assumption was gyro sensitivity. After serveral adjustments, and rechecking the mechanical linkage, I decided to disassemble the tail blade holders to see if there was any way to tighten things up a bit. What I found was the bearings were literally glued to the "SE Tail Housing" (what looks like it should be called a tail blade holder shaft to me). In attempting to remove the bearings, it destroyed one of them (they had been glued to the SE Tail Housing!...not just loctite). Then after removing the set screw, I attempted to remove the SE Tail Housing from the Tail Pulley Shaft. This resulted in bending the Tail Housing shaft (it was also glued! to the shaft.) I purchase a new Tail Housing Set, which was much tighter than the original, and everything now works great!
My leason learned was...if you want it done right...do it yourself! More importantly though, I would think Hirobo would not want to let something like that leave the factory for liability sake if nothing else!
Possibly the heli ARF's are going through the same growing pains that the airplane ARF's went through. Many airplane ARF kits are now excellent quality compaired to their first attempts, so maybe there is hope for helis also, but I have personally sworn them off. Has anyone else had any similar problems with the Sceadu ARF, or other ARFs?
