Hello Mike,

You are right, but it´s pure chance, that the new Hacker we judge now in our idea "as the next F3A step" is the same design like the first prototype of Q 80 11s.
You are right also, if you say, the Q 80 is a great motor.
I know the Q80 11s really good by myself and all what I could say is, that this design is nearly the optimum of power and efficiency we could get with the knowledge of today ..... if you fly the todays standard F3A props like 21x14, 21x13W, 22x12 etc. No question; that works fanatastic.
And no otherpoint was the demand of this design! The Q80-11s is optimized under wellkown ideas of the traditional electric performance.
But we have tried to think at the next step. And excatly this make the difference!

We have had the idea to fly electrified like YS-powered models. Please believe, we have tested many designs at the basic of the 28 Pole- version before we found, that the
" old" prototype of Q80 , named Q80 20P13s, is the best design for our new idea to fly with 20x10,5 props the same rpm´s like the YS. This version was no more a compromise, the rpm and Amps where exactly we want them and it was great to feel the drive-set in the air!
.... and this version works better and more efficient with these YS-props like the Q 80 28P 11s!

Again, the Q 80 28P 11s is still up to date if you want to fly F3A electrified like we know this since approx. 6 years.
And the C 50 line also (!!); this design is not old, only because we have had a new idea. The different C50 versions works great also. ( I was one of the biggest fan until 3 month ago...)
But the new Q80 20P 11s have the possibilty to open new doors at the electrified F3A history!
In Günter Ulsamer and my imagination, the new complete Q80 20P 13s-drive set better in F3A like the each traditionel drive set with rpm of approx. 6000 and props 21 / 22 diameter.
You should try it!

best regards

Bruno
