Kman,
I love building Guillows kit for the memories and they are just plane fun to build, I am not building to compete. When I built a model to compete with, normally I build it from scale plans and it has all the functions of a competitive model. With these Guillows I am just trying to get them to fly in a circle for 10-30 sec definitely not enough flight time for most competitions. So building a functioning nose block takes too much time for a model I am not even going to compete with. I now glue the plastic cowl on after I have balanced the completed build to include the rubber. I add my clay to the nose the nose then glue the plastic cowl on and if needed during trim I will just add down thrust to the plastic bearing. I am not using a long piece of rubber, for the most part just using the rubber band that Guillows sells
Believe it or not it is enough to fly once you lube the rubber. To place the rubber I tie it to a string and thread it through the rear. For winding I use this little winder, 300 turns and off she goes.
