Don't have a source to hand but I once was told by an airline training captain that at one stage ab-initio Lufthansa students were required to solo the Bonanza in around 6 hours from scratch, or get washed out. The RAF at one point also taught ab initio on the Jet Provost, though they subsequently reintroduced a pre-primary phase on SEP types.
So feel free to train on the Robin, and do some spinning and basic aeros while you're at it.
