Well, I can tell you that it's not a beginners ARF to put together. I had to re-do a few things my way. The tail section was not straight. So, I heated it with my heat gun and straightened it out. That took some doing. Hope yours is straight. I think it's a poor design to boot. It should be a one piece bolt on low wing design instead of plug in wings. The wing bolts are very hard to get at and you have to remove the canopy to even get to them. But I think we can't expect perfection for the price of $125! I have several flights on mine. It does pretty good, I think. It has a Saito .82 with 12x6 prop. Yep, it is pretty fast. But it slows down very well for landing. I might try more pitch on a future prop for a little more speed. Good luck with yours. I think you'll l ike it.
