David ,
Is this model being flown in the Uk ? If so the model and its operator will have passed all requirements currently in place through the relevant LMA scheme . I agree the models are getting bigger and more expensive but this must be market driven and I am constantly amazed at the technology and quality the leading manufacturers produce .I watched our JMA chairperson flying his large scale Su 30
? and bigger models certainly appear to fly and present better than my 45 size jets .
cheers Euan .
