Those are heavy duty model gears, they are used with 3kw+ inrunners.
Of course, those won't survive more than a few runs.
For the first stage , it's useable, the second one is another matter.

Happy Xmas to you all, thanks for everybodys help and advice and a special mention to Trev also, hopefully will be at many more shows next year, and remember boxing day is for robot building not shopping all the best Adam and louise
are these good beattle weight motors, including hub and banebots wheels

Yeah I think those are the exact same ones I linked the other day lol
Anybody in the notts area who could do some ali welding, need the flip arm plate welding on and some fins.
Ceros update all finshed bar some welding, and full weapon test
weight 88.2 kg with 1 bottle and no gas, so plenty of weight left for the hardox scoop
yay, will post some photos
Sounds good, and well done on the effort of giving it an overhaul!
Looking forward to pictures/videos.
Presumably your running 36v, does the technobots relay cope with that alright as it says its max 30v?Quote:

New flipper bar and chassis brace
Side strips to avoid getting stuck on its side 8mm aluminium water cut
Very nice!
Ceros new flipper arm 6.35mm t6 aly with 5mm aly braces and 5mm ti sides with 20mm steel bar for the ram to work on just need to make the hardox snow plough,
bettle weight spinner under construction 500gram drum mounted on 10mm bearings

ceros flipper test video
Is that a seat belt your using as a tether? How do you connect it at each end? Looks good btw.
Two holes and a flat clamp
4mm hardox scoop cut ready for bending and nylon collar to reduce ram stroke from 120 - 97mm in design, should have a new update by next weekend,
notoy has new 4mm aluminium base and is about 50mm smaller length and depth, gr01 fitted and axe mount cut
Final test c02 using one of trevs regs, starts at 8bar up to 12bar, includes new 4mm hardox scoop shortened ram know have 95mm stroke still plenty, just using the steel single buffer tank. seatbelt arm restraint straps with 4x8mm bungee on each side to close the arm, also all final fitted armour.
enjoy

That's looking amazing adam! Can't wait to see it on FP
id keep it low pressure mate, seems to have plenty of poke and will out last all the big flippers, will work well with your powerful drive... works for behemoth and makes for a more entertaining show.
looking hopefully to run about 20ish bar for a while at least, Durham soon so will be testing and winding up the pressure, I personally don't think it needs FP and the 6mm t6082 base wouldn't like it either. thanks for your comments
That looks brilliant Adam! Love the scoop on it as well. Any plans to weld small vertical plates on the edges of the scoop to reinforce it or do you reckon it'll be sturdy enough as is? Looks great either way, can't wait to see it fighting :)
Thanks for all the likes and good comments, see you all soon at durham and whitick if we survive the first event

no toys new chassis gr01 motors and 2xspeed 900 axe motors and 4mm aluminium base
That's more like it :). No more clumsy bludgeoning I hope, more a quick precise blow (your old axe was a tad slow mate :) ).
That Axe is looking evil, Axe off at the champs anybody?
Ceros vids available on youtube, ceros vs kronic, tilly tiberius not sure on spelling
youtube channel (louise hemstock) will send link when on my pc, enjoy
full test of no toy today, not good the caldercraft low rpm high torque speed 900 motors are gut less, running 6s twin motors the axe is slower then before its terrible, complete redesign required or genuine speed 900s pos. but the rest all works well and looks a lot more solid. may have to use the mfa motors from before and just overvolt them but I am tight on weight again
That sucks No Toy was looking good, hope you can sort something out
Does the axe seem to have plenty of power but just slow? If so you could reduce the size of the sprockets on the axe or increase the size of the sprockets on the motors.
Or if it seems to lack power you could try the reverse (increase sprocket size in axe) which could speed it up if the motors where under too much strain as they want to run at a higher rpm.
Other idea is shove a powerful brushless motor in there, but not sure how well that will go either.
It's a shame you don't have the space/weight for a scooter motor, they seem to work quite well
really lacking power they are low rpm motors but really struggle to get the axe to move it would need a large ratio change from 7:1 ish know to 21:1 ish I used to rum with mfa 4:1 epicyclic geartrain
What about the mfa 800/850 motors? They seem pretty powerful
would also require a 2 stage gear reduction, its the axe weight that causes the problem just over3.2kg
Wow really? It doesn't look that heavy, that's over double what mine weighs and I was worried about the weight of that. Seems a second stage reduction is the only viable option although you might need more powerful motors
Did you measure the amp draw?
No but couldn't have been alot as it feed though a 30amp fuse
6S 30A= WAY below the capacity of a real speed 900 or even the clones.
Kashei fries the PCB's of the motorcontroler, and that's normaly able to cope with 100A+, with 1 speed 900 (what fries too on a regular base)
Its running of an 30amp electronize unit, I wonder if they have current limiting ie, bridge bypass,or resistor bypass, might hook them upto the tz85 to try them again on 6s
The electronizes don't have any way of current limiting. If you overload them to much, the relais will pop, and if those fuze, the fets will go.
Testing it with a TZ85 is an option. But I suggest a 100A fast fuse then.
