I think were all on a mission to speed our eggs diablo, you'd have thought it would have been done so many times by now.
I know people say buy a halo but i like my egg but just need it faster reliably and preferably a bit higher to allow for battery fade.
I don't know why i suggested that you'd need an 18V motor, after all i'm only an ex-electronics engineer who knows a little about resistors and all that sparky stuff, so i think i must be senile now. doh
Here's some other stuff knicked from the dark side, just thought you may be interested, but i haven't tried any other than the servo mod
*EASIEST* Egg Paddle Mod BPS increase -- ~1.5-2
Cut off all your paddles but two and keep them in a straight line. Reinforce them with something long and thing like a Popsicle stick or sewing needle.
Z board BPS increase -- ~3
Buy and install VL's Z board upgrade.
Glory Hound's Gear Shave Mod BPS increase -- ~1-3 (depending on how well your egg was made)
How to do it is pretty simple. Well I'll give you guys the simple text only description now and later hopefully one with pretty pictures. Ok?
Diablo66 says: I tried this and it made no difference apart from the gearbox is now a lot quieter, but then i used silicon spray as a lubricant.
To begin with I had noticed my EVOII hopper was somewhat slower than the one a friend of mine had (Hi Ecco! You gave me the idea to do it), even using the same batteries, same board, same paint and everything. My hopper was also sounding louder than his. This got me thinking that there had to be some kind of resistance in the motor unit, perhaps the tolerances of the fit of the plastic gears inside?
What I did was I removed the motor unit from the eggo and opened it with a small electronics screwdriver.
I checked the fit of the gears and found them being slightly too tight a fit. I removed the center one and very carefully filed the outer teeth of the gear down a tiny tiny bit. Then I used a hobby knife to remove shavings and to scrape the bottoms between the teeth slightly. Then I checked the other gears, but they fit very well together. I cleaned all the gears from any plastic residue from the work on the middle gear. I also removed the grease internally, though only because I thought it might have little plastic shavings in it, and lubed the gears up with what I had at hand -PMI paintball gun oil. Any paintball gun oil would do nicely I think.
Finally I re-assembled the motor and then the hopper.
And that's about it. Doesn't sound too complicated does it?
Just be sure to note the placement of the gears, well they only fit one way but it helps a lot if you remember how they are supposed to be placed anyway before taking them apart.
Be careful, be gentle and even with the filing down of the gear and generous with the oil.
Also, the 9.6v batteries I use probably give about an extra 1 bps faster feed rate. So with normal batteries perhaps you'll get "only" 22-24 bps?
