Funny you should talk about inverted set up. The TT61 up right looks fugly, whole lump of metal sticking out. I set it inverted today. The carb will be below the tank for sure. You need to ensure that when you are starting up you should not choke the carb. Mine started manually after quite a few flicks, I did not want to use a starter. The plane idled well on the ground and in the air, no dead stick. You are stuck with the tank position unless you wanna redo the F2 to lower the tank, not really worth it.

As for my throws I used the recommended rate and no expo, she flies to my liking. I had to add 30 grams to the tail if not it was way to nose heavy. There is no need to come in fairly quick at all. She lands like a kitten. She will bleed speed off quick but the rate of descent is very nice.

I just need to get my engine tuning right and she will be really nie to fly. I love the way the Rambler banks ... very nice. I have only done 5 flights and not tried any acrobatics yet, I did do a couple of barrel rolls only. Will do more when the engine is properly tuned up and run in.

Enjoy your plane!
