Dear friends,
Brett has quite right about the recensions of journalists, mostly in case of stunt engines.
The story, ("curriculum vitae") of MOKI-51 is literally a "long and winding road", since it appeared still in late of 1987.
We (top 5 Hungarians) got 2-2 pieces for free, but looking at problematic behaviour, everybody remained by their ST 46 or ST 60s. (I by HP-40s). They immediately sold their pieces to abroad, just me reserved mines, as mechanically very good quality basement, for the future.
Leaders of MOKI -regarding to fiasco- modified the rest 2-300 pieces and sold them en gros to Australia and Canada, many of them with R/C carburettor.
I started to modify step-by step, and after ten years I put into my very first "big" plane, flying on fullsize lines, to my first WChs, in 2000. Now I can state that it can substitute fully a good ST-60. My colleagues (their team won European Ch in 1993) fly electric now: they never loved to play with mechanical engineering things, and they have right.
