Hints or tips for Stringbags? Probably too many hints or tips to mention here... I'd really recommend one of the WnW build guides advertised on thier web site. In particular the one with the Gotha on the cover. Short of that, I'd follow the WnW instructions as closely as possible. I have this kit as well, along with several other WnW kits. I make sure I'm thouroghly familiar with the instructions before I remove any parts form the sprues, and often make notes and annotations for various steps (especially the color call outs), right on the instruction sheet. I'd decide ahead of time which marking scheme you want to build, as the steps are keyed to each profile/color scheme, and there may be parts that are used/unused depending on the scheme. These early WnW kits (I think this was the third or fourth kit released) had very close tolerances-- so close that a coat of primer or paint interfered with the fit of parts in the cockpit, so you may need to remove paint from joining surfaces. Take plenty of time when rigging your model, the primary reason first time WWI modelers get discouraged is usually the rigging. The best way to tackle the rigging is to break it up into smaller sessions, rather than trying to do all the rigging at once. I recommend EZ line from Berkshire industries, (a model RR supplier in NJ) and available on the WnW website. If you take your time and follow the instructions, you'll be awarded with an outstanding model experience. Here's a link to a WnW Bristol F2B over on Large Scale Planes, built by James Croasdale, a fellow Canadian. http://www.largescaleplanes.com/articles/article.php?aid=997
And another by Dirk Polchow over on Hyperscale:http://hyperscale.com/2010/galleries/f2b32dp_1.htm
Finally, here's a link to Des Delatorre's excellent WWI modeling site -- WWIaircraft models.com-- there's no F2B on his site, but Des has some excellent step by step instructions for building and rigging WWI aircraft models. https://www.ww1aircraftmodels.com
Then of course, you have lots of Stringbag modelers here on Aeroscale to help too!
