Because it would rob power and over stress the tail components.

I ran the tacho at the end of my flight on sun morning and the Heli was over 2500 at the end. ( if you run a calc it says it should be lower but it ain't.) it runs for 5 mins at a time. And I'm still loving it. The same nano tech flight packs now with over 50 cycles a pack ( I have 7 pairs).

It has however got a vibration ( just) so will be running through the Heli once all the new bits ( set of bearings and dampners) I've ordered turn up. It also has a bit of play in the main shaft bearings so have ordered blocks with thrust bearings in to try. I'll keep everyone posted.
