Slipperntial my way. Maybe. - RC-Monster Forums

The loss is from friction in both the bearings and gears. Then the energy need to spin up the extra mass.

If keeping the overall drive ratio the same. The main thing I see you gaining is some lightness (which is always good) and a slight increase in acceleration because it will spin up a little faster.

Is it worth it... That depends on the rest of the truck. There are other areas I would look at to gain some speed. If there are other reasons behind the build like you want a clean look, adding lightness, or just like to have a unique truck then go for it. I have more fun building so, I would do it just because I could.

Basically, how many gear 'meshings' you have, the gear width, and the mass of these gears is what determines the losses. The smaller in diameter you make these gears, even with the same weight gear, the 'momentum' will be less and therefore less energy wasted. You simply what to keep a transmission as simple as possible, and as small as possible, while maintaining a healthy 'durability' factor.

But, I seem to be bouncing around on the topic, so I will stop now.

Maybe I missed something. Why did Mike build a V1 slipperntial?

The V1 Slip.? He designed and built that for racers... It almost prevents wheelies, and you will get very high planted acceleration.

Basically truggies/buggies to have their spur gears mounted directly to the center driveline (ie the centerdiff in their case) eliminating the transmission. You only really need a tranny if you wish to have more than 1 gear, otherwise you aer just stacking on gears (and increasing CG) for no good reason.

The sliperential basically eliminates the tranny and gives a MT (this case the Gmaxx or G2R) a buggy/truggy like drivetrain. Also, nitros have a clutch, so having a direct drive isn't that much of an issue, but given the solid pinion and huge TQ of a BL motor @ 0 rpm, its very helpful to have some sort of slip to not kill the driveline (esp as hardened pinions are rare, so plastic spurs are needed) and wheelie everywhere.

As an aside (I'm not trying to bust balls any

) but I've noticed you often spell "series" as "serious". First noticed it in a battery post. Just makes for a funny reading.

Like "these gears are not screwing around, they are in serious.."

Great. You have to jump on the speeling (spelling) impaired guy.

Your not busting my balls. I am Dyslexic.

Try spelling that one. Some people consider it a handcap. I really don't have to many problems except spelling. I try and proof read everything before I post but some things slip past my eyes. I thought every one here would get by but I guess not.

Thanks for the info about the slipperntial. I want to build one. The Emaxx transmission I have takes up to much room. Plus I have it locked into 2nd gear anyways. I was thinking of making a direct drive system right off the transmission but there is still the different gears to work out. Why not leave out all the extra gears and still keep a slipper clutch. In my view it clears up 2problems I hear people posting about. Just my opinion.

NP dude, trust me I'm not the grammar police, it just stuck out as it gave an amusing reading. I had a GF in HS that was dyslexic and a good freind in college who was as well. Neither could spell very well, but were gifted in other ways. Both were incredibly intellegent, creative and artisticly minded. Made me always wonder if dylexia was just an alternate way of thinking and perception of information (not a concious choice mind you, but innate.)
