RE: H-9 Arf's Check this out
I'd like to add a thought or two.
This is an imperfect world we live in, populated by imperfect people. To expect perfection is a frustration and a dissapointment. I don't expect any ARF to be without flaw. Some are much better than others, but none are perfect, or will be, I suspect.
Those of us who have been around awhile, need to help those trying to decide on their 'third airplane', and show these newcomers where to look for flaws in these ARFs. They are there, you just need to know where top look and how to fix the problems. It is still a lot easier and faster than building and covering one from scratch, something that would be beyond many newcomers to our hobby, if only for the time facter. Out of all the ARFs in the air on any given day, how many simply fail without some help from their pilots. Rare is the failure in the air. The percentages are in our favor, and I contend, with proper care given to the assembly and with feedback from us in forums like this, the owner of one of these ARFs has every chance to have success.
I had the Sig Sukhoi ARF a few years back. It was having an unusually high incidence of apparent wing failures that I happened to read about right here on RCU. I had mine ready to fly, but decided to strip the bottom covering off anyway, just to make sure I hadn't gotten a bad wing. I had! It would have surely failed. Sig was replacing them, but I didn't even ask. I knew how to fix it, and did. No problems.
I would enchourage anyone buying one of these planes to seek help, and read all you can, if new to the hobby, and use your experiance if you've been around awhile. Don't cut corners in building, and don't try to build beyond your knowledge. Learn first, then apply what you know. You will have more fun, be safer, and save a lot of money.
