I checked out the site. It appears that the engines are of decent quality, and are side exhaust. The availability of a pipe from the manyfacturer suggests that they would be timed for that style of running.
I imagine that a lot will be decided by what level of competitor the manufacturer wants to attract. the money is likely to be made by catering to the sport competitor.
If catering to the sport competitor, I would suggest lowered timing and a typical 4-2-4 break. There are a lot of engines being manufactured today to that standard. An alternative would be the so called 2-2-2 running engine. More of your high rpm, low pitch style of run.
The sport competitor will be most impressed with value for his money.
The weight of the total package will be important.
Americans prefer to run some amount of nitro in their fuel. I persoanally like to run FAI fuel in the engines I use. The answer would be to provide good instructions and additional head gaskets.
If catering to the all out competitor, one who tries to compete in the upper ends of the pileup. I suggest looking at the top competition engines in the world.
Look at Randy Smiths PA series, or the Ro Jett engines from Richard Oliver for ideas for a piped style of run. Remember, these engines also run well using a muffler.
For something in the Classic 4-2-4 run, take a look at the Stalkers, and Belkoff's (sp) designs.
There will almost always be a place for side exhaust engines in Stunt, but notice that at the high end of competition, rear exhaust seems to rule.
These are all choices the manuifacturer will, or should consider when making the decision to break into this small competitive market.
