I just purchased the Skybolt and haven't begun putting it together just yet. I'm very excited about this kit. I'm hearing it is one of the hardest kits from GP to put together. I'm thinking of going with a Saito 150 up front. I'm looking for any tips or anything that anyone has come across that I should know of before entering the building stages of this beast. I'm also looking to throw a smoke system in it, but do not know where to start with that. Any suggestions? I have an Extra 300s with an OS .91 two-stroke running a TME smoke system. I had to get a specialized muffler and had to poke around to get it to fit/work right. I want to try to make the smoke system stage go as smoothly as I can with the skybolt. This will be my first biplane. I will hopefully take pictures of the building stage and post them on here as I progress.
