I am nearing completion of this "free plan" model and I am wondering if anyone has any recommendations regarding the type and capacity of the battery. I am considering using 7.2 or 9.6V AAs. Your thoughts will be welcome

I discovered this build diary on RC Groups boards and thought it may be of interest (could the builder also be a member here? don't recognise the name - 785boats )

page two has a brilliant (to my way of thinking!) way of making cowl vents...

Yes, Paul has an innovative way of doing things when it comes to his builds.
