Winter build Hpi 5b

[Mick Boomer]

Do not get ceramic bearings ever. Obr will even tell you that. Unless you plan on rebuilding every race like top fuel dragster nhra guys do. Stick with nachi and stock seals.

That’s good to know wasn’t sure they were worth the extra cost

The only reason I wanted a balanced crank is because ill be running a carbon chassis. I don't think carbon will soak extra vibrations like aluminum will. I believe aluminum is more rigid.

Is this gonna be a dragster style build or a off-road?

 

[Z.hb71]

ceramic bearings are dogshit

 

[Mick Boomer]

Offroad!

 

[MonsterAir]

What tires you gonna run?

 

[Mick Boomer]

get uber. with the 34 reed your gunna be spinning like your on ice with the hostiles. ive tried both amd ubers hands down win

 

[Mick Boomer]

These hook up in my field. Very short grass with soft ground.
But I agree z. I think the ubers are better. Would like to see the weight of a uber tire compaired to mx’s. Weight is key here in my build especially rotating weight.

 

[Z.hb71]

i think they around the same weight

 

[Milo]

But you’re not using a obr 32ss with balanced crank so mine is different

 

[Mick Boomer]

Omg! Got parts in today. Ddm spur weighs a ton. Its definitely going to my buddies machine shop for holes. Retarded heavy. Kind of ridiculous in my opinion….

 

[DougStar]

Put my ddm spur on the scales last night 290g

 

[Mick Boomer]

He wont touch it since there heat treated. Im mad. Even offered 75 bucks

Just run it ......I did since I built my baja and it was good

 

[Mick Boomer]

I just don’t understand why there not lightened. The spur is a half pound. Crazy. 8, 1/2inch holes in it would substantially make it lighter.
Spun weight. Hell it even makes it harder on the brakes stopping it. But I guess thats the point. Money
This is a mod in my opinion someone can make money on without having to change an entire clutch system on.

You need to find someone with a water jet so they can cut it

 

[Mick Boomer]

Found a local machine shop that has a water jet cutter. If it turns out good ill buy a bunch and have them cut.
