I have a question I have a Saito 100 I will be using and i am debating on how to install the engine and looking for opinions. I can mount it sideways and the muffler will stick way out to the left or inverted and it will be at the bottom right or my preference some where between sideways and inverted with the muffler exiting the bottom. Let me know what you guys think. Also i hope i dont get banned for saying this but i would really like to do the military version of the cub what do you guys think? I am not sure how easy i can get the N numbers and lighting bolt off the covering is super coverite i have never dealt with this covering before . Any thoughts to leave it as is or should i go for it?
I know this plane, my friend has one. He flies it with an OS 70 on it and he recently rebuilt it after an incident with a slap happy tree that ripped it apart. We played around with the engine position, and basically found that if the engine is mounted inverted without dropping the tank it has a good chance of flooding with a full tank. The FA100 is a much larger engine, and its spray bar sits lower than the OS when inverted, I know, I wanted to invert it in my SIG cub, but it would require dropping the tank floor which was not worth it. With the 100, mount it on the right, with the exhaust pointing down, also put a piece of fuel line on the crank breather and run it out the side by the exhaust, or make a scavenge tube, or you will be cleaning a lot of slime off the belly. If you can find one, use an Evolution 15x6 on it, flies it very scale like at half throttle, with some ooomph at WOT when you feel frisky. Mine is on a 1/5th SIG Cub, and its first flight was with a 14x6, went vertical on take off after about 10 feet, Way too fast a prop for the Cub. A 14x8 MAS gave good performance, but again, too much speed for the Cub. The big difference between the GP and SIG, your has a solid one piece wing that does not require the struts, where the SIG struts are 100% functional. It also has a slightly longer wing, not true scale like the SIG. It will fly real nice with that 100 on the nose.
