10 to 1 gear ratio
What is the motor you are using? Looks very golden... and powerful... and expensive!
And loving the milled Aluminium btw :-)
The motor is a scorpion HK4035-560kv, 4.2kw and running on a 10cell lipo about £100 on ebay.
what rpm is the shell gonna be spinning at?
It spins about 2000 rpm and is 6.54kg and 580mm dia.
That is a meaty motor, What capacity is the 10 cell lipo? My robot runs two speed 900's at 6 cells and the capacity is 3000mAh which I suspect is much more than I need. Weight and space saving to be had in short. And two of those would be a serious upgrade!
Is the 10:1 ratio new, or the existing ratio from the previous champs? Because it's always looked like it's spinning waaaay faster than 2000rpm, especially when you rev it up high!
Although it could be down to the fact that the whole body is rotating and is quite large, so looks much faster...
But the upgrades look very nice, hope they do the job. I have to admit though, it's quite worrying reading about NST and LS4 getting upgrades to make them more reliable. They're deadly enough already :uhoh:
The battery capacity is 2600mah and have never used half of that in a fight but any less capacity
would decrease the max current draw too much.
It was 10:1 last year and most of the time ran it on half speed to keep the robot in the arena.
That was 1000rpm!?
Just goes to show how important weight, diameter and bite is.
Tried to test on friday plugged the link in and nothing happened, the scorpion speedo did work a year ago so dont know why its not working now but it hasent blown up so mark may be able to fix it but on taking it apart i found that only a few fets were touching the heatsink pad, so much for quality. If mark can get it going i will modify this and use it as a spare.
