But taking it this far is kind of silly for a $15 transmitter.
You got ripped off Steve. I only paid $7.00 for mine.
Rajah235 is offering some for pretty cheap....
I will need your address............................ when they arrive.
I always run the cheapest alkaline batteries I can find & not bother with re-chargeables.
(I like to supply the rated voltage.)
A local hardware store has the "Varta" brand, Alkaline on sale for $8.90 for a pack of 30.
So, I bought a few.
I run these in my Spektrum Dx5e on my IOM yacht.
All this talk about the "dead band" on these Tx's made me think. (Hard to imagine, I know.)
I shall endeavour to check the new/spare Tx against the original.
I didn't see any great "play" in the sticks, shaft to pot region, but will investigate further.
After-all, the axis shaft is just pushed into the pot. It ain't a press fit.
(As Steve found out.)
On mine...There's a slight dead spot in the left aileron when first applied.
The right aileron works smoothly, with no hesitation.
I put this down to the mechanical set-up & not electrical. The pots measured O.K.
