Default Advice on building my first LCG rig

Hi,

After 2 RTR-s, I am looking for advice on building my first LCG rig.

Goals:
  • End up with a crawler that outperforms my near stock Capra (RTR + Proline tyres + brass portal caps in the front + 1080 ESC)
  • End up with something flexible that is easy to change / improve later; avoid lock-in
  • Do not break the bank
  • 2S, if possible
I have no plans to compete, not interested in adhering to any rules, just want to have fun.

I plan to start with the following parts:
  • Capra axles. KYX axles from Aliexpress, but I replace the housing with Axial plastic housing - I don’t want any aluminium on the underside of the car. I was considering straight AR44, it is even cheaper, but my local terrain begs for portals.
  • Fimonda Frame Rails (link)
  • Element skid to start with (until I can get my hands on a delrin one)
  • Element Stealth X transmission. I want to try out just a bit of overdrive, but not much
  • Desert Lizard shocks in full droop configuration
  • HobbyWing Fusion SE 1800Kv

What do you think about this? Does it make sense?

My biggest concern is the “extra” 1.92 gear ratio in the portals, combined with the 3 gear transmission. Final Drive Ratio is 90 (huge difference to stock Capra FDR of 25). Is the FDR 90 OK? Will it work with the selected motor? On 2S?
The second concern (that I’ll just have to try and see, I guess), is this frame too flat for the portals? Would I be better off with this one instead?
The motor and the axles are the most expensive parts, these are the ones I least want to replace.

Thanks for any advice. Don’t hold it back!

PS. I am in Europe, some parts (e.g. a delrin skid) are not as easy to come by as in the US.
