This is not exactly a flat bet system - but thought it might be of interest. I have used this mechanical system with some success in REAL casino simply betting the Red/Black EC. It also seems to perform well over 100 spin sessions.
Please note this DOES use a progression of 0.5 unit after each 2 consecutive losses...
To begin session: Wait for a single formation of a color to appear eg: RRRB or BBR
'========
STAGE A
'========
Bet the opposite color to the last spun result.
If WIN and level or ahead of current highest profit then restart from stage A at 1 unit stakes.
If WIN and still less than current highest profit (behind) then restart from stage A at SAME current stake level.
If LOSE go to stage B.
'=========
STAGE B
'=========
Bet the SAME color as last time ONE more time. (eg if you bet RED last time; bet RED again)
If WIN at stage B and now level or ahead of current highest profit then reduce stake to 1 unit and go back to Stage A.
If WIN at stage B but still behind current highest profit figure then keep to same stake level and go back to Stage A.
If LOSE at stage B that means you have lost twice in succession. WAIT for color sequence to end first and increase current stake by +0.5 units and resume betting at stage A at that stake level.
Recommended aim = +5 units.

+5 in 55 spins.
If a ZERO occurs during betting I accept the loss and repeat my bet for next spin as you can see in above session.
For this reason best to use single 0 with le partage rule.
A.
For stop/win I would suggest +5
For stop/loss I would suggest -54
Losses
=====
2 x 1
2 x 1.5
2 x 2
2 x 2.5
2 x 3
2 x 3.5
2 x 4
2 x 4.5
2 x 5
I think not to go higher than 5 units...
Max -54 (approx) total risk/loss.
