Re- A7, There is larger size kit produced in Germany, Iam not sure exactly who manufacturers the kit or if it is still available. If your interested I would suggest contacting Franz Walti directly for more info on A7 kit availability etc as he has a nice looking RTF A7 for sale listed on his website, go here and click on 'second hand'- http://www.Jettech.ch/e-eingang.html

Re- B1, Dean Lassek (A10FLYR) was working on a nice big one, just maybe Deano will chime in with a progress report if he see's this thread.

Cheers-
