1:8 Buggy with 2x3S Lipo Setup?

Hi.

I want to buy an 1:8 Buggy to convert it to brushless.

The Setup i want to use is the following:

2x 3S Lipo Zippy
Medusa 3660-1800
Mamba Monster Max V3

I still want to buy a brushless conversion with motor mount
and 2 battery trays like the Novak 5015.

Is the Ofna 9.5 Buggy a good choice to convert to brushless?
Or should i order an other buggy to convert it?
Are the diffs, cups and bones durable?

I hope you can help me, because the setup is already here (i don't want to buy new Lipos, because i have already a lot of 3S Lipos), but i need an 1:8 buggy to convert it.

Thank you for your help and sorry for my bad english.

Greetings,
Firebird.
