What you say would be nice, but I'd have to say it's wishful thinking.
All but possibly a couple of the Speed events added to the Regulations since the mid 60's have been 2-line events. They are (or were) popular, relatively speaking, but I think the fact that they were new had more to do with that than the 2-line part. So, my point is that there are plenty of U-Control spec Speed events for someone to choose from.
I guess I don't understand why Monoline gets such a bad rap. I started flying Speed in 1967 with a McCoy 60 "C" Speed model. One of our club members had a Ringmaster fitted with Monoline. After three flights on it I was turned loose on the McCoy. The first couple of flights were not pretty but I didn't crash. Admittedly, the people helping me were Carl China (Viper B Proto), Harry Roe, Jerry Roselle, and Jack Frye. All of these guys were nationally recognized speed fliers. But still, I had to figure it out. Frankly, having flown 200+ mph "D" models I would not want to be anywhere near one being flown with U-Control. Monoline is stronger and safer. Of course, the problem now is the availability of key components, especially the twister.
The plane. Technology only goes forward. The current planes are just faster. That's what it's all about.
The fuel. Oh, how I wish we could have nitro back. But the history of that is all caught up in a tort liability incident so that simply won't happen.
One final comment. I was looking through some model magazines from the early 50's the other day. There was a letter to William Winter where the writer was complaining that Speed was headed down the path to degradation because fanatics were cutting on their engines to gain more performance and guys with access to machine shops had some unfair advantage. And so it goes...
