... funny ... we fly 4 years with active regulation and now I see "no one used it till now succesfully on F2B circle" ... we probably use in in speed circle :- )))))))))))))))))))))

I know (beside me) another source of such thing - in use for example by Jiri Vejmola (2 years) ... so now I count minimaly 2 sucessful solutions

Exactly, I know and tried 3 different systems, all of them work to some extent, but most important is, that it must be well tuned, if not, it is far worse than constant rpm 
... I wrote it already, the fun with electric power train did not start yet ... or better ... just starting :- )))))))))) ... fiddling like with tuned pipes length will start soon :- ))))

It is, but sometimes it is not enough ... for example light model with little mass inertia can benefit on such regulation, it is visible in extreme on indoors:



This is old video and probably everyone saw it already, but I wanted to show, that even even with such regulation, shapes are still not good, for exaple in loops, they are not perfect circles, they are tilted elipses, it will need even stronger regulation, also speed on top of low figures is low, while speed overhead is already OK :- ))))

and here you can see my actual regulator in action ... still not perfect (I must solve short power boost in corners during winter) ... but it is already clear, real fun with electric only starts now ... fiddling like with pipe length, nitro content etc will come also to electric, and we will need modern electric "tuners" :- ))))))))))))))))))))
