It's fun to think about what it might take to beat Draco in the STOL Drag races.
Rik's turbine with that weight has a superior power to weight ratio.
Standard wing KF is faster than Trent's. With the available power, acceleration to Vne will be quick. Beta prop deceleration at the line could be the deal breaker. Again there is plenty of power with timing being everything.

The overall power to weight ratio compared to Draco should be a distinct advantage.
Big tires would enable a larger diameter prop, but might require some positive thrust angle to counteract drag, but this would also help during heavy deceleration!
The airplane would be pretty much a purpose built machine, maybe not practical for everyday use, but I think a capable competitor!
