Thanks for the great advice.

I think I will try and keep it as a taildragger now.

So, should I rebuild the vertical stab larger too, or is simply making the rudder larger going to be enough?

What is the smallest size tank you would suggest for my OS FS30 four strokes? I want to try and put the tank inside the wing so that I don't have to build huge nacelles that extend halfway back to the trailing edge.

Thanks again. Steve
