Running a Kyosho Optima brushless?

[OptimaSwede]

Hi,

does anyone have experience with using a brushless set in an old Kyosho Optima?

Mine is the original one but with a full ball-bearing set and a OT-74 from a Turbo Optima.
It still has the standard chain-drive

I'm on the way to get myself a new ECU and motor so if it works, why not a brushless set? Still, I'm not interested in ruining the gearbox/gears/chain-drive.

Thankful for creative comments and information based on experience with an Optima or equivalent (Javelin etc.). Used brand, type, turns etc.

Best Regards

Running the Optima on std chain with ANYTHING over a 16T motor is likely to stretch your chain and render it useless, would recommend either sticking above 17T or get yourself the Belt drive option set W-0105, I have used the belt drive option with a HARD pinion gear with a 6.5T brushless system which runs fine, just dont be slamming from forward to reverse constantly and you will be fine, worst will happen is stripped spur gear (about £10 for a set) or broken belt (unlikely but only £5 to replace).

Hey, I'm thinking about running my Optima too. Do you know where I can find a hardened final pinion?

Ebay but you can expect to pay upto £30 for them as they are rare and those that run these need them, hence the price is high as everyone bids on them. Could do with getting some made in hard alloy they would sell like hot cakes lol.

Hi tamkyo-RD!

thanks for the information. I have a Pro Stock 15T motor from Yokomo lying around so I think I will test that one. I will just try not to push it to much (if that is possible)

You don't happen to have a Belt drive option set W-0105 lying around waiting for a new owner?

Have a nice evening

I stretched my chain back in the day with a set of 1400 scrs and a 17 double!

God knows what brushless would do.
