prodigy evo

[ady]

so after 3 years i got the old girl back. I am waiting for a few more original parts to arrive such as weapon gearbox and frame.
taking the easy option, wrap it all up send it away for rebuilding, as fabrication for spinners were always past me. I want to keep it with the same look,but evolve it to move with the times, basically just better and more power, initial plan is to go brushless with lipo's.

its first outing will be robochallenge next event, this is the current full time project, will add more pics as it progresses.

Re: prodigy evo

all parts have now arrived, just ordered brushless motor and speed controller from hobbyking, then shipping everything to mario for sum fabrication work.

also ordered lipo's and charger, next update will be weapon test, already salvaged an old microwave from work to test it out on.

i cant get over the weight saving going brushless with lipos, lots and lots of extra armour me thinks!

Re: prodigy evo

Prodigy evo mk2 has now arrived with Mario. brushless motor, speedo, lipo's and charger sorted.
So far it has been a case of organising parts, the disk has been modifed to take a 20mm shaft with new bushes and bearings, replacing the original 15mm.
The shape will change it will b a lot shorter than it was, pics will follow as the rebuild progresses. It will be finished early December to coinside with its first competition before end of year.

Re: prodigy evo

update

Brushless motor Magnets are glued in with epoxy, the axle is turned around and supported on both sides.

Weight, with LiPo, drivetrain and brushless speedo, 8.3 kg.

looking forward for it finished, and do some tests, good work mario!

Re: prodigy evo

i guess;

500kv hobyking motor
6s lipo (turnigy?)
1.5:1

?

Re: prodigy evo

270 KV Turnegy.
Tz85 speedo. (with programming card)
5S 5000mAh Turnegy LiPo
1- 1.2 gearratio.

All electronics are Hobbyking.
There is something like having mortgages, families and stuff.
I wish the budget streched to Castle Creations and so.

Be interesting to see how well it spins up, that ratio might be a bit optimistic for that weight of disc and motor combo, You done a spin up test yet?

Re: prodigy evo

Not with the current motor.

But with a simple batterydrill it went to 1000 rpm inside a second.

Oh well, I alway can make a new belt-disk, if I would make a 160mm one, the ratio goes up to 3-1. (end speed, theoreticialy 1640 rpm then, still a nice wallop)

It's not that the belts are a problem. I weld them myself to the right length. And buying it per spool is cheaper.

Re: prodigy evo

I was just asking what components they were to work out if it'd be any good- not how much they cost Ady.

And as i said i think the ratio is optimistic at 1.2:1, but hopefully it'll work out.

Mario - A battery drill has considerably more torque then that motor will have from stand still, theres no comparison.

im sure it will do for me, as long as i can have some fun with it. Never look to win anything
my pocket money went on my electric bike which set me back £1500, and i dont want to throw lots into a robot that i can only use once or twice a year.
i have an old microwave from work to test it out on when i get it back so will upload a vid.

Re: prodigy evo

yeah get some video's posted when you get chance ady, be cool.

It's the first time I work with a brushless.
I'll know tomorrow, as we set up the speedo.

If the amp meter and temperature gauge tell that it ain't a good thing, I easely can turn another belt-wheel. Up to 230mm (biggest diameter I have around).
