Hey Tom,
Do you recall how much elevator trim you had on your plane. Secondly, did you add any thrust in the motor box. If so how much? What prop did you use. I am currently using a 22X8. I am thinking about running a VESS 23B, but I think I should have purchased a 23A. I think a 23A is similar to a 23X7, but I am not sure. I have never used these props before. I am trying to get this bird ready for IMAC. I think the 22X8 would be good for 3D. Any advice would be great. I know you have a slightly different motor, but I belive overall horsepower must be similar. I live at 6000 feet which would make a diference.
Thanks in advance
Brian
The Sboch isn't fine tuned for IMAC and we didn't change the thrust. We live at 830ft ASL. Kind of hard to compare props.
I have a DA-50 in my Extra. I personally like the 22-8 Xoar. Similar performance with Vess 22-A. A friend has a Vess 22-B and has lots of pull out power with it. We both have Pitts mufflers. I tried a 23-8 Mejzlik and got lots of vertical but I didn't like the way my plane flew. This is all personal and things are probably different with your set up.
If it was me I'd try a Vess 22-B first.
By Elevator trim I'm thinking you mean throw. . I have very little elevator for precision Flying. It's Close to 7 to 8 degrease of deflection. I started with 15 Deg. and cut it back till I liked it. Each airframe is different and depends on where your C/G is. That is also personal preference.I like my C/G close to neutral. (Easier for me to do rolls.) You can only get that C/G by flying and adjusting as you go.
Hope that helps.
