| The difference is in startup sequence. You can try it with any e-glider. AC engines with "normal" ESC has troubles with low rpms, most of ESC has a quite big jump at the low limit of stick - it means that AC motor start at 500rpm or so and it is a big shock for gear (normal propeler in e-airplane) does not care about that.
Heli need really "soft" start of the engine, otherwise gear will be stripped. I have tried JETI non-heli prototypes two years ago in ECO8 and the result was damaged free wheel as well as some teeth gone on main gear ...
So, I hope I have explained that topics - the benefit for the is gear-friendly environment and little bit lower probability of the next crater in the airfield, beacause of the gear malfunction ... ;o) |
