There are several different types of remote control helicopters, ranging from simple, easy to fly models to complex kits that must be assembled

Maneuvering autoratations were always uncomfortable in rotor speed stability in my few hundred hours of R-22, compared to the Bell-47 and Hiller autorotation stability and ease of autoratation. This was true even after attending the Robinson IP course.

While it can generate more power (non-derated), the rest of the aircraft (transmission, powered components, rotors, hubs, etc.) would need to be beefed up, and more usable weight lost in a larger fuel tank (which necessitates a larger body… and more weight).

This is the same problem race car designers face… for every pound you add to engine weight you have to add a lot more all around, and you end up winning less… which is why they always strive for light. The same is true in helicopter design.

I suppose it would be designated the R88.
