It could be tricky to get away on a calm day, as it needed a javelin-like launch. A stiff breeze made life much easier!
My first one flew straight off the board, with little interference from me! Just as well, as I had virtually no experience!
It only got interesting when you started applying the rudder (no elevators!), as it was very responsive. I learned a lot from that model, and it always brings a smile to my face.
As others have hinted, yours sounds somewhat over-powered and probably tail heavy. Check the CofG carefully! Also, if a smaller prop doesn't help, try fitting it backwards to reduce the thrust.
Best of Luck!

There are a lot of encouragement and suggestion from members of this forum. I suspect that the model was 'controlling' and 'biting' me for failing to understand it flight character!
I am going to try a smaller prop and perhaps even fitting it backward!
