No nose weight was required for my bird. I built the tail feathers from stick and was very careful about adding weight especialy aft of the cg. Someone once said of aircraft design, " if you must change something add simplicity and lightness". My plane is modled after the racer and the spinner was removed. This simplified my spinner problem. Having said that someone supplies a spinner in aluminum for this size Bristol, just can not remember who. It was pricy as I recall. I would suggest keeping the pilot and cockpit simple and light. I just painted mine and added a sport pilot figure from Williams Brothers. Built my own wheels as well. Here are some photos, and I will be happy to answere any questions I can.
