If I had one, I'd install it, just to have the "science" behind the performance. I also would like to track the "rf" environment and whether or not it is being affected by some form of radiation off the long Ignition power leads. But I don't....
I would be more interested in how the voltage is effected by the servo current drain.
Here is how it looks on my Weeks Special with 5955's on the ailerons and 5995 on the rudder.(NI-CD 6V 2400mah)
Note that there are spikes reaching down to 4.8 V
on the 2400ma cells -unless they are better than those I have seen- I would expect that kind of droop---under high demand
When I tested my 2 cell A123 - vs 5cell new -conditioned - 4300 MA NiMH - they were close -but the A123 held more voltage under same load. any of my smaller packs were simply nowhere near voltage at load .
the real tell ,is in using a electric motor which will pull 40 amps - the 123 simply hold voltage thru effective charge
I also compared with 2070 ma LiPo in dual 11 volt packs (3x2) and the 4 cell A123 again held higher voltage at same amp draw
to be fair - the LiPos started at 12.4 volts and the A123 at 13.5 volts
but- the combined Lipo amperage rating was 4000ma and the A123 --2300 Ma
better yet - the friggen Lipos had to be shut down befor they reached 60% of pack use -or they commit suicide.
The A123 ?
I just run em down till they quit -then charge right back up - I got rid of the Lipos
I used no test equipment except a simple VOM(the Astro Whattmeter .)
