Frank/Dieter;
I can understand why you might be skeptical--but all I can tell you for sure is that I built a Marabu--finished it as my first electric with the retracts Dieter sells and everything with the plane seems OK quality-wise. I have built other ARFs, and the Marabu was well thought out. The builder can always .make little mods here and there if he feels the plane might benefit from it, but other than adding triangular stock to the motor box to beef it up a bit, I didn't see the need for any changes.
It seems to me that he's trying, but Dieter's first love in my opinion is vintage pattern and developing the planes. The "business" end of things is much harder with many production obstacles to overcome.. He may be trying to do too much too soon. Personally, I think he should slow down a little, get better organized, and take it slow. In the US we are accustomed to everything being worked out BEFORE the models are marketed. For example, my Marabu came with instructions in German, (not good if you are an American customer),and I didn't feel all that confident building the plane. Fortunately, I have a German friend who translated the instructions, (not all but the most important parts), into English for me. After that I was good to go. Now anyone who buys a Marabu has those translated instructions. I think these kinds of things should be worked out in advance in order to avoid confusion, and in the case of the Arrow, you can see we have too much confusion. Everything might be fine, but to us it appears that Dieter is ahead of himself when it comes to the glo version of the Arrow.
The market for a good ARF of the Arrow will be there when all the production problems are worked out, and everyone will be happier. I know that Sky Aviations needs a cash-flow, but on the other hand, people have to be SURE, (have confidence) in what they are buying, and that the company has its problems in check.
This is my best advice--I wish you well Dieter because we need quality ARFs of classic pattern planes. Take your time and get it right.
