Powerbox 'Royal' Spectrum in over 20kg models?

Nigel if the aircraft you are referring to is the Fokker DV11 you registered in October 2010 then your appointed Inspector is Ian Turney-White and you need to discuss your radio installation with him as he is the LMA Inspector who will "sign it off".
The only Powerbox system that meets the LMA redundancy requirement i.e 2 battery and 2 Rx inputs is the Powerbox SRS which recently replaced the Powerbox RRS system which is also approved.

Tony thank you for the reply.

Yes it is the D.VII you referred to and I will be discussing it with ITW before I make a purchase naturally. I was just looking around to see what was approved for use and your second paragraph answered my question. Powerbox 'Royal' Spectrum is not approved and Powerbox SRS is approved.

So I can now draw up a circuit and a offer it to ITW for comment.

Thank you again.
