I am finding it to be a rather pain to assemble for a "trainer". My H9 Arrow was a snap compared to this. I will beef up the firewall and fuelproof it. I already have larger wheels for it. Those little foamy ones were a joke. The covering is peeling back in many places but some of that is likely due to the very hot and humid conditions lately. The hinges I beleive are of the robart type and pretty easy to secure. Some of the parts in the box did not match with the instructions and some of the steps in the instructions were done already. I had a plastic cowl on my HZ Super Cub and I went through three of them due to nose bumps on asphault landings. This will be landed on a grass field so hopefully that extends the life a little longer. The LHS owner said a guy he knew had one and had a few years of flying time on it and liked the plane. I sort of wish now I would have spent a few more and got the H9 Alpha to complete the circle on my H9 trainers as I have the Arrow and P-51 PTS. Oh well, like i said... I got it cheap and you often get what you pay for.
