Team Death - New Heavyweight

[team death]

We used 2x4500s (4s) zippy lipos in series, they wern't fully charged I think
Adam said they were around 50%-giving us around 15 volts each so
a total of 30 volts.
What was your optimum set up for the Radio control Katch giving
you the best results?.

[katch]

I used Dx6i with Receiver ar610 I think ..

Left stick Forward back - Speed / ( Receiver throttle)
Right stock Left right mix - Combines motors tank steer ( Receiver Aylerones )

After my first install ( more luck thank judgement) I trialled out the other channels and I didn't get full throttle... but I've never read the manual for dx6i so I could have potential fixed it I just played to see if there was a better combination. Just a suggestion as possible contributor..

I'm testing mine with 12v x 2 and 12v x 3 24v/36v - 200 kilos this weekend. ( bot & 100kg ) so we'll see what happens or breaks.

Only things that affect yours differently to mine that I can see...... may be useful or you can just ignore me

- Chain friction - dry chain is up to 6 - 9% power loss on motorcycles, Using motul wet road lube is by far the best, almost no fling or mess.. so on smaller power sources is a huge power drain. They over heat and snap or get a lot stiffer a they warm up, they also stretch super quick when dry as in 1 inch in a single short ride. Always spray the inside of a chain so centrifugal force push it into the chain where it needs lubing. If I need a chin drive i'll be using 428 O-ring - no stretch no maintenance in comparison. Grease is retained inside the chain so almost never stretch how we use it. Not much heavier.

- Batteries can produce volts with low amps its like a tidal wave - it can read 15v and have 1 amp behind it. You need a lot more than 1 amp ..I've had plenty of arguments with workshop customers, where they claim a battery is NOT at fault as its 6 months old, but we have load tested it and showing 13.5v but fails loads test, barely enough power to light a bulb.
I would try it fully charged

- Your wiring is half the thickness of mine. reduce draw ? not sure .. I have ZERO bullet connectors all big red things

- Your motors are they used ? 24v ? MY used ones are notably slower than my new ones.. worn brushes or bearings

- Gearing combinations, I don't work stuff out I learn and play with trial an error, but...
I see you used a DID motorcycle chain etc - not sure where but... for reference and guiding you.. you can offer it up against your sprockets..

Example Aprilia rs50 - 12 52mm - 47 225mm ratio is 3.92 for a 12bhp motorcycle that weighs around 100 kilos.

So your 24v motors are being expected to work just as hard ( with internal gearbox ) without the benefit of a gearbox, but move the same weight.

Dropping to 10 tooth front -47 Rear is 4.70 - significant acceleration benefits and much faster movement since we operate at sub 10 mph I would go to 8 tooth front if I could.
