The only downside to mounting the heatsink to the chassis I can think of is stress on the components. Con't forget the heatsink is thermal-epoxied to the FET casings - and that's it - so all the stress from jumping, rough terrain, and bad landings will be transferred directly to the FETs, which are relatively fragile. Unless you plan to do something different, the FETs will also be supporting the weight of the entire ESC and all the G forces will be acting on the FETs.
