This 88mm X2 Elf was the platform where I found the swet spot for 2" props on 2s, this is about as small as you can build a rig that will swing 2" props but still carry a battery big enough for 3+ minute run times with motors that make good power.
This was also one of the more challenging builds I've done, I used MuteFPV's build guide on Youtube as a starting point and then improved on it over time. The biggest improvement was to put the VTX on the bottom of the top plate so that it's fully protected.
As I dialed the build in it evolved into a light weight (56.3 gram) high performance setup that sacrifices a bit of durability. It still takes a crash really well, but if you're looking for a basher rig this is not setup for that right now.
As you can see this comes with a ton of different props so that you can see which ones you like best but my favorites are the Gemfan 2035's that are currently installed. It also comes with six 2s 600mAh BetaFPV branded GnB batteries that have only been cycled around 20 times and absolutely rip.
The F4 flight controller is fully soft mounted and the tune is locked in really nice as you can see below.
