I'm a very late starter to rc heli and forums so please be tolerant with me. I have a Firefly trainer equipped with training aid, my aim is to fly a 450. Being a retired M.E. I hope to contribute to this very worthwhile site as I progress on the learning curve of heli flying.
My first tip: Wrap stripped bell wire or something similar round plastic core of training aid, add super glue resulting in a reinforced centre
