Going to introduce my 5 year old daughter to the world of balsa kit building with this model. It's special to me as my dad built the same airplane for me when I was about the same age, 37 years ago. I built several RC kits years ago as a teenager, so this shouldn't be too big of a challenge but do the FF experts have any tips or advice? I'm sure the rubber band will need replacing, any good online sources for these?

Thanks!

ps: This is the original Cloudbuster with the box shaped fuselage and polyhedral wing. Around 30" wingspan IIRC.
