Has anyone flown one of these 1\2 A gladiator ARF's? I just bought one so if no one has a report I guess I will. The price is right and it looks good. The picture is not coming up now but it was when I made the purchase. http://www.brodak.com/shop_productde...ProductID=8644

The biggest problem with the Lil' Satan is it is just too small. The key to a good flying combat plane is wing loading. Most of the modern fast combat models are around 500 square inches. My modern 1\2 A foamy is 260 sq. in. That is huge compared to a Lil' Satan. Knowing how to get more power from the engines helps with the speed but wing area allows the design to turn without stalling.
The first time I saw a modern combat design fly (1990), I was absolutely amazed. I could not believe how fast it was, and at the same time how quickly it could turn. After talking to the pilot, who had asked me to launch for him, he taught me a great deal about design. The other surprise was the thick airfoil. The speed came from sheer power, and the turning came from weight, wing area and airfoil.
I think from a design standpoint, combat models are magical. I am very much looking forward to getting my first Russian 1\2 A.

Consider the time frame in which the Lil' Satan was designed. I think it was designed for the Babe Bee of that period. A modern 1/2A engine has probably 3x the power of a single bypass Babe Bee.

The Gladiator showed up yesterday. It looks pretty good. I get the impression that this was manufactured in the orient instead of europe. Either way they did a good job. The center rib block where the engine mounts is made fro that typical Lewan type mohagony that will compress and is really not suitable for engine bearing. What I will do is add a small strip of formica laminate to act as pads. This is how the Litehawks were built (Larry Driskall's design). It is a combat plane though and any extended life expectancy should not be expected.
The covering is a little wrinkled typical as well. nothing that does not look like it will come out though. I really like the bladder compartment. It is a small closed end tube. No chance for leak here. The overall impression is very good as it is light and I am sure it will turn well.
The weather has now turned bad here but as soon as I get a chance I will get in a flight and report on it. I will either start with an AME .061 or my really hot AME .049. I am on the waiting list for the next batch of Profi .049 engines which from what it sounds are the most powerful available right now. 42' lines will be in order when that arrives. This airplane is as big as anything that would have had a .15 on it years ago. Just goes to show how far we have come!

I have it ready to fly but it is about 5 degrees here right now. One thing I have learned, even if you can brave the cold personally, the bladders do not work well at all. I have never been able to get a consistent needle when the temperature was under 30 degrees.
I am also now on the waiting list for a new profi .049 engine. I think I would rather fly it with that then my .061 AME engine.
