FLM ext arms on Elec Stampede
 

I recently got the full FLM chasis kit with extended arms and some other stuff. It didn't say in the description that I need to replace the driveline but do I need to? I got the stock length chasis. If I do, can you please tell me what parts I need to order? Sorry don't know all the technical names but it seems like I need a longer driveline to the rear drive wheels.

Yes you need these:

You might also be able to use the jato setup but not 100% sure...

the output axles will need to be drilled out for the bigger jato u-joint. On my next RC, I'll be using the Jato driveshaft with FLM axles.

BTW, for the price of these FLM parts, it would be nice if they'd include some directions.
