Kits are pretty hard to come by but there is a site with several of the old Royal kit plans that are being sold. They come with all the templates, instructions and they also sell the canopy's and cowls if required. Very good prices but you would have to cut you own kit. Not hard at all. Try a goggle using royal rc plans. If you can't locate the site PM me and I will try to give it to you. I have it in my favorites but haven't figured out how to send the address to anyone from my favorites file?? Totally computer stupid, sorry. There are a lot of the Royal warbird kits/plans there, about $25.00. If you have never flown one of the old Royal planes then you would be in for a treat. I have been eyeballing the Stuka for a while now. I may order the plans for it this week.
I pulled it up and the address shown is rc-royal.com price is $24.00 for the Zero
