Short answer: yes.
Hydra has plastic hand grips that are the same as the ones found on STUN runner. The inner workings of the yoke are identical and unlike the STUN Runner those handles come with thumb buttons. If you have a real hardon for the right handles they are a simple bolt on but you'll pay a premium for them online. Someing like $40 per half, that's $160 for a set.
I can't recall if Hydra has the same verticle axis limitation as STUN Runner but even if it does it's a super easy $5 conversion, you just have to take a backet off and add a spring that's easy to source.
