[NSRCA-discussion] DX7?

[Jon Lowe]

I wrote this for RCU sometime back.

Several things the DX7 doesn't have that makes it not very friendly for 
pattern usage:

No variable trim rates. Easy to end up between trims, and the trim rate 
is very course.

No throttle curve. I've made a quasi curve using the suggestion someone 
online came up with, but it doesn't substitute for a real curve. This 
is a biggie in my book.

No conditional mixes. I use a rudder to rudder mix to get a higher rate 
for stall turns switched with the throttle stick at low throttle. 
Doesn't appear possible on this.

No origin mixes.

No built in mix for knife edge. Uses two separate mixes to do it. The 
lack of origin mixing can affect these.

No multipoint mixes.

No split expo rates so you can get different rates for, say, up and 
down elevator.

No built in mix for two elevator servos. Only two mixes include a trim 
function, so you use one up to get this. Why EVERY computer radio 
doesn't include this is beyond me, given the number of two servo planes 
on the market.

No snap switches. I use them only for the avalanche, as I can get 
better timing this way.

Sticks were the softest I've seen, even when set full stiff. A set of 
HD springs helped. Sticks are smooth though.

Transmitter doesn't balance well at all on a lanyard, being very bottom 
heavy due to no antenna. We added a lanyard hook extension helping this 
a lot. This is a chronic problem with JR radios, and the lack of a long 
antenna just makes it worse.

This is a sport radio, and as long as you don't expect more from it, 
you will be ok. If you are used to a full function radio, especially 
one as easy to program as the 10x, you will get frustrated quickly.

I have been taking a serious look at the Spectrum DX7 Radio for 
Pattern. Are there any features that a pattern flyer might find lacking?

 

I understand the AR7000 is the right receiver, but what are the range 
limitations when the AR6000 is used?
