perfecting a simple FPV frame design

gistfile1.txt

- arms like Bridge City Burnside (distinct motor mounts/fingers).
- top-plate strap indentations (not slots) like BotAFX or YRZ.  (straight; not curves)
- top-plate screw positions wider than lipo.
- servicable stack screws, not blocked by arms.  nonbinding screw-hole like Moxy/Skyliner/CL1
- pressnuts on bottom plate, 2 per arm -OR- 1 in arm, 1 in bottom-plate (Apex).
- arm-screws are not stack-screws.
- unsure split-deck or solid-bottom.  split-deck seems better for "noise", but solid-bottom easier for arm-replacement.
- 8 standoffs, if full-schoolbus. 6 if fpv-cam-cage
- true X, 6" arms @5mm, 5.5mm, or 6mm arms -- must allow 6" props.
- bottom-plate hole for iFlight type hard-soldered ESC capacitors
- 30x30 and 20x20 stacks
- back should allow for any analog or HD vtx. (multiple mounting-holes deminsions) 20x20, 30x30 and others.
- i like the super basic TPU fpv cam mounts (like Flossstyle), but i also kinda like the idea on the Moxy frame (old round style).

optional considerations:
- through cam-plates and top standoff like Moxy
- universal fpc cam mount/cage like Wu Tank / syncmode
- depending on durability, slots for toilet-tank. (not necessary)
