The 4 gear conversion worth the extra $$ and weight ?

thanks

Yes - at least the US R40 comes with F & R diffs.

Grease/oil - depends on track.
Rear - try no oil ( light dab of grease on gears & shaft) to as thick as 30,000 weight silicone.
Front - try 30,000 to 70,000 thick silicone.

I use OFNA Diff Lock Oil ( Silicone ) but there are many out there.

Basically, you want the front diff "tighter" than the rear at all times. Tighter meaning to use a thicker silicone oil.

4 gear conversion - probably not worth the $$ IMO. Although, I just dissasemled my diffs and found the spider gear shafts worn down pretty bad. This indicates that you need to keep the lubrication on these shafts.

How do you like your WASP motor? It's PICCO based right. Do you have trouble tuning it? I saw this on E-bay and it's a modified edition.

Hey man my engine is awesome... real easy to tune, it's powerful as hell and I love it for the price, I also use the pipe and header in combination with an OS turbo plug p7 medium... it kick butt
I you wanna try it it's a lot of bang for the buck... check them out at towers mine is the blue one that has 1.45 hp at 37,000, but there is another one for $30 USD more that hits 38,000 with 1.5 hp...

thanks ...

Pat
Tabushi: I use 40k to 70k oil in the front, light grease on the rear just to maintain lube...
Now I use the front oneway for tracks with less brake, but for small tracks I use the rear solid axle in the front diff with a high torque servo...

The US version comes with front and rear diffs. You can use grease in them if you only want to lubricate them. You use the diff oils to tune them to your track. Higher grip tracks will allow you to use thicker diff oils.

The 4 gear diff will work more consistantly and smoothly then the stock 2 gear unit. It also provides you with more mechanical drag so you need to lighten up on the diff oil. You can mix diff oils or partialy fill the diffs to fine tune. The 4 gear diff won't work well on low grip surfaces. As for cost, you can just buy the shafts and gears seperately for not much money.

looks good. bet you can't wait to run it a few laps.

I just put the lt weight chassie on last night and just did the 4 gear mod in the rear. the shaft in the rear diff was badly scored.

I'm closeing her up now so I do some laps tommorow afternoon.

anyone know what size bearings I need for the steering? I gotta replace those silly plastic bushing.
