Yes the 3D-RV is very similar. Thanks for the pic.
I used 2024t-3 because it is stronger than 6061T-6 But I can get it for next to nothing. I work for a major airline and small pieces like that are scrap. We use alot of 2024 and 7075 but not alot of 6061. So it's just for convienience for me.
I should get the tail in a couple of weeks, I have to drive to North Carolina to pick it up. I have to do some storm clean up this weekend, from hurricane Frances, We got alot of wind and trees down.
Oh yeah I still need rotorblades.
