Thanks for the suggestions,

at this stage I think I will try the cable tie with fastening block to the fuselage. The Dave Brown attachment also looks good so this will be the second choice if I can get one to fit (http://www.radiosouthrc.com/thumbnail.asp?cid=60).

As I need to make all the needle valve adjustments to my .40 before I fly there will be plenty of time to see if the cable tie type of fastening device comes loose.

Cheers
