[NSRCA-discussion] Spektrum AR9100 RX

[vicenterc at comcast.net]

Troy,

The reason I would like to try the AR9100 RX in my pattern planes is that I am using two LiPo 910 mah now.  I like the idea to have a backup battery.  Yes, I will need to use a regulator because of the servos but it appears that the RX does not need regulator.  I know that I don't need the heavy wire for the application.  It will be nice that they make one with JR/FUB plugs. 

I was thinking that I can replace the wire with pig tails my self.  For sure I will go ahead and get one AR9100 for my big gasser.

What is the difference between 921 and the 9000?  I guess is just brand-name but want to make sure before investing.

Thanks,

Vince,

the 9100 RX is designed around High current draw applications. Our models don't really require that. The RX is heavier than the 921 or 9000 RX's and part of that is the large battery leads serving the RX. I suppose you could use it but you are not going to be gaining much. Its designed around the larger applications that are 33% plus or in things like Jets with a large number of servos with higher stress applications.

Our pattern models are drawing power in the 1.5-2amps max...this is peak and worst case usually. I have done some testing to make sure I'm carrying a good battery supply. Using a 1650nimh or 2300nimh on 4.8V is working for me in even the Bipes...Another good solution is the Jaccio regulator with a lipo or Li-ion at about 2000-2400mah capacity....

The 9100 RX is designed around models that might be using (5-6) 8711 servos or even more...and could be pulling upwards of 2-3-4amps or more.

At these currents and loads the normal RX switch and lead from a switch to the RX is not sufficient to carry these high currents for very long....so the 9100 RX is a solution to this application as it has large 16ga wire leads for power into the RX. This adds benefit in the high current applications but not really anything to our pattern models...other than weight.


I'm flying the 9000 and 921 in all my models now. Would not go any other way.

Hello all,

Just would like to know opinions on this product. Any one using it? I like the idea of the two batteries input and the soft switch.
