RE: Carl Goldberg Ultimate building tips needed!!!
I also originally wanted to mount the servos in the tail, but there wasn't enough wood to mount them, unless I added some braces to the fuse side. I didn't want to cut the covering on the sides but didn't mind the bottom.
I wasn't able to get the split pushrod to give me even deflection on both sides. I also didn't like the amount of slop and springee feeling you get with the split pushrod.
I also lost one elevator side due to flutter in my first kit built ultimate which is why I decided to come up with something better for my ARF version.
I did have to add weight to the tail, I think it ended up being less than two ounces. I think my YS 1.20 is pretty much overkill this is not meant to be a fast flying airplane, and I never usually get above 1/2 throttle unless I want to accelerate going strait up (which looks pretty cool) IF I was to do it again I would put in something smaller and lighter (engine) so I wouldn't have to add weight to the tail and I could use my throttle above 1/3-1/2.
