Heres a better picture, This whole thing gets One big heat shrink over it.

makes a difference hey

The Zac project OS12TR has bucket loads of power, excellent for a track like Mingara with a good size straight and good traction I really love this engine.
The novarossi on the hand has a more lineal power range, nowhere near the power of the Zac but its pullstart so it shouldnt have! Its just really tuneable and well matched to a car like the v-one-s even if otherwise stock.

I guess i like both engines equally but for different tracks.

Brett

yeah i love my rossi too

Im pretty fussy on stuff like that, every 4-6 weeks each car gets pulled down to the last screw and nut, checked over, rebuilt bearings flushed and oiled evrything cleaned....usually takes about 6-8 hrs and about 1 litre of metho!

Brett

yeah i am like that

if itwasent for the scratches on my chassis u would think i bring a brand new car racing ever meet

squizzytaylor

yeah same here, I got a bit slack over christmas though cars got a bit dusty....so did my driving.
I like working on them probably as much as racing them but I think thats an age thing more than anything else

Brett

nah i like both the maintainance and the driving

i have allways been like that

Im very curious, how does a 2 speed transmission work?
Its confusing to me.
How does it go from speed 1, then shift to speed 2 transmission?

Brett

the 2 spped works buy the first gear getting the sharft that its running on to the selected speed for the clutch/ dog/ cam engadges and then 2nd kicks in, first is disabled becaseits running on a one way bearing

ahhh thats a rough guide

xGSiR

you made me lost! lolz.

i still don't understand :/

Brett

ahhhh i knew u would say that sombeodt take it from here i need sleep

As compli-cated as It all may seem at first, the operational aspects
of a 2-speed transmission are actually quite simple to understand. Power from the engine or motor starts the whole drive process. First gear engages as a result of the
connection between the clutch and the clutch bell on the engine itself. As the engine's RPMs and (the car's top speed increase), the 2-speed's clutch shoes or arm will kick out and "grab" the bell housing via centrifugal force. That's when second gear kicks in. First gear is actually still being driven by the engine, but it's not turning the RPMs to keep up with the RPMs of second gear. That's why there is also a one-way bearing housed inside the larger first gear or 2-speed bell housing. When second gear has engaged, the RPMs become so high that the gear shaft support-
ing the gears actually free-spins inside the one-way bearing, thus disengaging first gear.

Hope that helps

well said

i knew what i was talking about he he

V-One S

I asked the same question once,
I was explained it, now i know how it works

But I'd have every1 in worse a shape then before i started explaining

U follow me there?

But i asked mine to my LHS when i was first starting Nitro.

I dont see why they dont make 2 speeds for electrics.
Or do they?
Cause then they would go a little quicker.

(540's i mean)
