I have installed the speed limiter from bmt and breifly read about it but never used it. They do come as standard equipment. Looks like a quality piece of equipment.
I don't really understand why anyone make speed such as issue. I think the people who do would be suprised to see that most jets fly well below 200. Some jets are capable of reaching this infamous level, but dont do it in normal flying conditions. Most jets fly around 120-160. I think flying styles have changed and speed isnt really an issue like it used to be in past with ducted fans. Aerobatics have become more prominent, not high speed race track patterns. Thrust to weight isnt the answer either. A stingray with wren 44(7lb) will do 200, but I doubt a eurofighter with a P200 would do 200. Speed isnt the safety issue. How many accident are speed related? I would bet the highest amount of accident come from equipment failure. So why would we want to implement another potential equipment failure? I've never had an accident because I was going to fast. But I have because of an equipment failure. Weed out the peolpe who shouldnt be flying and make it challenging to those who are beginning who will prove their ability. I attained my waiver fairly easy, but I had much practice with many different models. I dont really think it has anything to do with how long you been flying or if youve flown ducted fans. I saw a kid start flying a few years back and far exceeded most of the skills I have seen of many of others modelers in just a years time. I dont really know what the answer is, but is there really a problem?
