I made a spreadsheet to compute speed of every designable tank/vtol with editable stats. It may be usefull for those who want to mod weights and speeds or just to see that except for bombs engine upgrades are almost useless for VTOL
When speed is displayed in green it means that it is capped by the propulsion max speed. Change stats on the third page and adjust engine upgrades on top of the first one (from 0 to 9 in the regular game). I took the formula from the guide but it does not explain how to compute offroad speed which may be more interesting (also heard of a 50% bonus in some cases which does not appear
At least if the speed formula est crappy it can be just a proof of it
