Wayne - the plans are form MAN 1959 - not sure who the designer was - but I enlarged them to suit two 40s.
The drawings leave a lot to be desired - they showed the tank going through the LE and also the leadouts going through the tank.....a bit weird, added to that the ribs did not have the cutouts in the right place for the spars - so I ended up cutting 2 set of ribs - and marked the correct locations
edit: the cowls are from the Brodak catalogue - they are 4" diameter
Chris, AND Paul, I have had a clean bech policy for a while - almost a year .....just makes life easier when you come back to do stuff....
and it is a stunt PRINCE yep - hes a boy
