I'm curious why are some people getting or recommending AR6100 receiver
over AR7000 for DX7 and Trex 450 As far as technical specs go 7000 wins
over 6100 so is it because of size and weight difference?

6100 is only 3.5g while 7000 is 13g but could one really notice 9.5g weight
difference in flight, even if only slightly? Is there something else I'm
missing?

Price could be one of the reasons but let's ignore that for a moment - if
they were priced equally would you still get or recommend 61000 for Trex
450? If so why? Thanks.

If the weight of the heavier Rx gets rid of the shitty tail heavyness of
most of the electric heli's on the market, then yes, 9.5g is a huge
improvement.

To get the nose heavy enough to make the heli directionally stable.

All of my 'leccy choppers balance right at the flybar.. Not a tail
heavy one of 'em in the bunch and except for my micro, all the Rxs are
in the rear.

Place your gear carefully and you can get the CG right where it needs
to be. Just keep the high voltage stuff (battery/ESC/Motor wiring)
away from the low voltage stuff when you're running wires and you're
good to go.

shitty tail heavyness

No doubt caused by the first piece advised given to anyone who buys a leccy
heli ....

"Get rid of that crappy but really light gyro and replace it with a really
heavy GY401"

Cheers,
