I plan to build in simple FT style out of foam board, what would be considered a mid sized model. It might be a little less rounded and scale in some areas but the profile will be faithful(for example, it will look as much like a scale Dash 8 as the FT Viggen looks like a scale Viggen jet, If I do it right). I plan to use two 250 size motors, 2205 or equivalent, possibly Graupner 2806 ultra 1900 KV motors, or FT radials, mounted on FT swappable sized firewalls, and use these 5040 6 blade props https://www.amazon.com/dp/B01L25DCP6/?tag=lstir-20 for the best scale look. I can see no reason why I'd absolutely need rudder action to fly this, especially if I do thrust differential, so this will likely be a 4 channel AET yank n' bank, but if somebody more experienced knows better and thinks a rudder would add a lot of performance and be worth the extra channel, let me know!
I have read the FT quick guide on twin engine planes, and plan to review the video and Josh Bixler's podcast about twin engines again. I think I have a pretty good idea about the electronics part of wiring a twin engine plane. I also plan to research guides on setting up thrust differential with the FS/Turingy I6 transmitter. I know this topic is frequently addressed here, and I plan to do my own research and look at some of those threads, but in the mean time, if anyone swears by a certain guide or instructional video that helps me learn to configure my twin engine planes, I'd really appreciate if you linked it here. Also, if anyone has any advice on the subject to share from their own experience, I'd be grateful for your help.
