[NSRCA-discussion] Advancement system

Mon Feb 13 17:02:56 AKST 2012

This I agree with. Guys should have at least one contest of not two to determine they really should have moved up.  I really feel for a guy who thinks he is ready, makes the jump and the first time he is in front of judges realizes he wasn't ready. He should be able to move back down.

Why all the rules to let you fly what you want? Why do you need to stay in a class after the first contest – Why not after the third one?

Did we become Congress or something?  One more example of trying to figure out how to have a rule for everything. While we are at it, lets put the judges in cages just for that one pilot that lands to close to the judges. I am all for verifying fail safe and such, but I don't think we have to require device on top of device to fix things. Wait til your caller goes to pull out the arming plug and doesn't pull straight out and cracks your fuse. Most arming plugs are as hard to remove as the battery connections. I am all for safety, but it needs to be the responsibility of the pilot.

Prior to takeoff, it is the caller’s responsibility to hold the airplane once the batteries are connected and not release the airplane until it is set down on the runway.  After landing, the pilot does not taxi back but rather the caller retrieves the airplane and does not let go of it until the batteries are disconnected by the pilot.  The CDs should remind the pilots of this procedure during the pilot briefing at the beginning of each day.

How quick some that abandoned glow for the latest rage never discussed the tradeoffs they were truly accepting.. I always figured if "E" power was all its was being claimed to be it would be cheaper and more viable than glow.  After reading all of this thread it seems the exact opposite it. When I return to competition it will be with the safe glow go juice or not at all.

They are definitely better now days, but far too often I see guys do things that open the door for disaster (I'm not saying you're doing this), and it's pretty scary. People just don't always appreciate the danger involved.

If everything works as it should no one will get hurt, but the potential is there for serious consequences.

They have been know to malfunction, so the safest approach, as Earl suggests, is to assume that anytime the battery is connected to the controller the motor may go to full throttle. Until you unplug the battery the thing is hot and dangerous regardless of your fail safe or switches on the transmitter.
