If all else fails, look at the Bertella plans (Italy). 40.00 EURO plus 25.00 Euro shpng. His is TR1 version-1600mm long, wingspan 2615mm. He has canopy. Dynamic Balsa has(had) 8' foam wings. I drew my own plans for the TR1 I've been tinkering with for years. I'm now building an SU27 from Bertella plans and they are not great, but better than nothing. If you've scratch built some, you can work with them. Absolutely no detail/instruction! His are for DF but easily-I think-convertable to turbine. Good Luck, Bill
