Roller coaster entry

[DeaninMilwaukee]

I just saw an article in one of the modeling magazines about how to do a roller coaster.

Very informative, but in practice I have a problem with the very first step. :(


Your supposed to enter flat and level with throttle at 1/3rd, and then pull up hard which will make the plane 1/2 loop, but also almost stop and go backwards.

Sounds simple, but in practice, if I'm going fast enough to make the 1/2 loop, I don't go backwards. If I go just a tiny bit slower, it won't make the 1/2 loop, just does a stall/fall.

Whats the trick here?

I've seen this same technigue in video's as a fancy entry to hover, and I could'nt figure it out then either. :confused:

You need lots of elevator travel to do this maneuver, just as all other 3D-style maneuvers. Something to try is to give a shot of throttle just as you pull up. I've attached a video where you can see as I pull up hard, I give that shot of power to keep the airplane from falling out. It isn't a full 1/2 loop, but you get the idea. It doesn't take full power to do it; about 1/3 if you're starting from idle.
