ok im looking at kits on rb and first of all i thought these things were like $400, but i guess not.



my question is, whats the diff between these two kits, other than the obvious from the parts list, and why is the "race" kit more expensive? is there anything in these kits that i wouldnt really need in order to save some money?

also, i read somewhere that the fb 13b has 3mm seals, is this true?

does this one from atkins have everything i need?



guess i should put up the link... http://www.atkinsrotary.com/store/customer...&cat=590&page=1

the race kit is cheaper, they have the carbon apex seals

sorry i meant less expensive, which is why i was asking, it seems like the 3mm carbon seals would be more than the stock seals

just use the rotary aviation kit.

thanks for the in depth advice

Yah really, mind telling the benefits of using the aviation kit?

it's cheap and it works.



what more do you need?

ok, i suppose the silicone/teflon coolant seals are a big plus...they're reusable too https://www.nopistons.com/forums/pub...#>/biggrin.png
