Df-03 spur gear

[scorcher-tec]

hi

i am trying to track down a 78 tooth spur gear for a df-03 so i can do this

i have found a pack of gears on the bay but can't get any info on the amount of teeth. can anyone point me in the right direction to get one.

thanks in advance

What motor are you planning to run? The 78 tooth spur and 23 tooth pinion gear is a useless upgrade!! The FDR is worse than the standard SRB gearing. Try 82T spur and 19T pinion in 0.5 module size to get a ratio that will be right for a powerful motor that might actually need a slipper clutch.

A DF03 Spur gear bag has a 78 tooth and 85 tooth spur. The DF03 slipper set has the 82 tooth spur.

Hi

TA-Mark

I am gonna use a 13.5t brushless and 2 cell lipo in my scorcher

I have seen the slipper clucth mod by yourself and Rulok which both use the 78t 23t combination. is this not the best ratio? is 82t and 19t better?

if I use the set up I am planning will I not need a slipper? it is only going on the beach

thanks in advance

I'm using a MambaMax 4600Kv and 7.4v 100Amp Li-Po with the 19 tooth pinion and 82 tooth spur. One might call this extreme in a SRB.

I know I have the 23 tooth pinion and 78 tooth spur pictured, but this was only because I was still waiting for the 19 tooth pinion to arrive from the UK. If you read my description I listed both ratios the 0.5 module gears make.

The 78/23 ratio combination is useful for silvercan motors, for which a slipper clutch is not needed.
