I would like to thank everyone for their very kind comments, they are much appreciated.
Gregory - it is hard to put a figure on the time I have spent doing the rigging, it is not a job that can be tackled in one go as it is very tedious, hard on the eyes and back, so I need to take plenty of breaks. Add to this the inclusion of turnbuckles, there are 28 just on the tail booms and it takes time to fit each one. As a rough estimate I would say I spent about 12 - 15 hours doing the wings and 5 - 6 hours doing the tail booms, I still need to add all the rigging under the bottom wings which will include another 12 turnbuckles, then there is the control rigging for the rudder and elevators, luckily for me I love doing rigging, it is my favorite part of building these WW1 aircraft models.
