I would definately like to hear how you get on, and when the plane is finsihed we would love to receive some photos to add to the gallery section of our website.
To ensure there are no problems, run your 90SP on a test stand for approx. 2 hours before mounting in the plane and flying. The SP series engines really do benefit from this longer running in period and you will certainly be rewarded with your patience, with a smooth running, reliable and long lasting engine.

Best regards
