Yes Nigel it does look a great bundle.
Lots of real improvements on offer. Cowling, engine, that distinctive seat etc etc.
If I hadn't already built this kit, there is one particular detail which would have motivated me to go for it: Rickenbacker's plane had those attractive posters pasted to both wings, but in the basic Roden kit they were printed on paper, and you do kinda notice the thickness once applied and stuck down. Aviattic's decal set for his plane naturally includes it and I'm sure it'll look much better
