If it has the same performance as a Beta 2 it shouldn't be a problem, as far as I know Beta and Beta two have the same drive system, I would be more concerned about the engine, doesn't more HP mean more stress on the engine? If the Beta 2 engine is derated to less HP to increase the life of the engine I would think that an increase in HP would give a decrease in life right?
I'm not a mechanic though and I'm just guessing here..
The video says it was waiting FAA certification in 2010, would be interesting to know if it did get certified and with what limitations?
