Both the Bane Bot and Whyachi gearboxes are made in china. The only difference between them is the casing of the Bane Bot gearboxes are aliminium and the Whyachi ones are steel, making them heavier but not really stronger (screws pulling out of the ali ends sound more like the first failure point for both). And of corse Bane Bots are cheaper and have a much wider selection.

How difficult is it mounting the colsons onto the banebot motor shafts? Do you need some custom hubs or can you modify them yourself? Interested in some... _________________ ( •_•)

There are no pre-made hubs available for the bane bots gearboxes. The colsons I have have a 1/2" bore and the gearbox a 3/8" shaft. I made my own ali hubs on my lathe. I don't know how the americans do it because I have never looked. I don't see any "simple" way of attaching a wheel to the shaft without a purpose built adaptor.
CNC Bot Parts can do some up for you (

) but they are not cheap. Best to find someone fiendly who owns a lathe and broach set (why did I say that?). _________________ Get Some!!!

Haha don't worry, someone else has a lathe slightly closer... Hah that's if I ever decide they're better than standard drills, of which i've had no problem with so far(and I doubt the metal gears will help much when jolt gives them a beating!) _________________ ( •_•)
As can be seen, a "Watt's Up" power meter has been added to ensure I don't overload the LiPol (
http://www.modelflight.com.au/rc_model_electronics/watts_up_meter.htm
). With the robot pushing a 6kg tire against a gutter the motors drew a max of 25A. The solenoid valve draws 0.5A.
The problems found with the robot are:
1/ Radio interference problems. While Philip never had any problems with the ali shell, for me the robot is uncontrollable. An external antenna will be needed.
2/ A strap was added to the flipper arm to prevent it from going all the way over and is returned by an elastic strap but the strap gets snaged and will not return easily.
3/ The coathanger wire holding the strap to the arm snaps under load.
4/ After the last flip a large leak occured in the pneumatic system, possibly where the burket valve attaches to the buffer tank. I will need to look into this. _________________ Get Some!!!

I have found the "leak". The Burket valve is stuck and will not close. _________________ Get Some!!!

The easiest way to clean the Burkert is by pulling off the coil and taking out the four screws underneath. There will probably be a small piece of crap in there. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

I do that on a regular basis in all my fp robots as standard maintenance.
You'll see a stuck burkert happens when you least want it, in the arena, therefore i always take the precaution to clean them before i go to the event.

Is there a good way to clean paintball bottles? _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

With the valve on top of the bottle I shouldn't think that they would ever need cleaning.(the inside that is). It seems that the buffer in Devastator could do with a clean tho. _________________ Get Some!!!

If you have weight spare. you could add a regulator and valve set at around 35psi to 50psi for the return. ( could even get a way with 10psi)
this will use some air. would depend on how many shots you're able to get from one tank.
It look as tho you could easily lower the firing pressure to the cylinder.
would still be able to throw other robots and get more shots out of a tank. _________________ It's all about the destruction.

Devistator can flip about 26 times or once every 7 seconds. You don't need to conserve gas.
So how would you flush the buffer? Could it be rinsed with water and then dried in a low temperature oven?

The ram is a single acting only so a spring return must be used. The problems with the current setup are only minor and do not warrant lowering the robots performance.
As for cleaning the buffer, flushing with water and then drying sounds good to me.
The robot currently weighs 13.05kg with a full CO2 cylinder. _________________ Get Some!!!
