errr.... actually it is not a copy... it is the original! HK bought out the sole rights to it ..... don't ask me how I know!
One of the reasons I did not post anything further on it!
However, I can tell you that the production version had several improvements from the prototype;
1. Dual rear servo pushrods are solid pieces x2
2. All venting holes in the fuse are pre-cut
3. Inner frame has been totally redesigned to allow you to remove the FC mounting plate for very easy access to the wiring.
BTW- The photos on the HK site is of the prototype...the very same one!
That one died after an inflight blade failure..... and yes the Tri is not very repairable... but at that price.... who cares!!!!!!
