Well I found my old 'record breaker' ...... 222kph recorded with 4400kv 450 Heli motor ... 3S and 4.75 x 4.75

here shows with its 'normal' motor .... before swapping out ...

Shows how small the PKJ ... and imagine that has a 4400kv Heli motor on 3S with 5x5 ... later ran with 4S on 4.5x4.5 and she hit over 280kph ...

And I found the second one that I tried twin Heli motors on that just would not fly ...

Initially flown with single and then modified with twin 3800kv (250 Heli motors)!!  The idea was to try and break the 300kph barrier ... I got close with my first at 280 but was unrecorded ... 

Those PKJ's were small !! designed for a 5" prop on a 1400kv micro motor ... 2S normal ... 3S for a bit more excitement ... we were throwing 4S at them !! 

Thinking to resurrect !! Maybe not so much to hit those speeds again ... I'm a bit older now !! But might be interesting to chuck up in the air again.

HK stopped selling them and then produced another but smaller ... wasn't big enough for us ... so it all died down.
I'll fly anything if I can launch it ! Youtube : solentlifeuk

Resurrect, it`s the way to go, just for old times sake.
It would have gone faster in the warm weather🙂
Wot, no Depron?

After having some hairy moments having guys hand launch it ... I added the Bungee launch to her inventory and guys heaved a sigh of relief !! 

This is a slow flight ... but gives you an insight into the 'adrenaline rush' it gives .... believe when you are struggling to stay in control - simple things like trimming are hard to sort !!
