Many of the suggested ones are already available from many sources so for me, I would like scale models that are not so easily sourced already but have real character
Number one
Supermarine Sea Otter (but with U/c so it can be4 flown off land) size approx. 5-6ft wingspan, IC power or elec
Number two
Edgeley Optica as long as the cockpit and annular ring can be offered as part of a parts kit (size/power as above)
Number three
Grumman Martlett (English Wildcat) or Bell Airacobra, don't mind which (size/power as above)
Sorry it is 4 aircraft but whilst loads of Hellcat models/plans seem to exist, there seems few of the last two modelled and even fewer, if any of the first two in the sizes suggested that are big enough to have presence and small enough to fit most transport.
Love your Hurricane (I have two of them) and your recent Mossie! Looking forward to flying my Mossie in 2016
