Jucava: You can get into situations that are hard to recover from in a trainer if you don't know what you are doing. That is one reason why I'm not a supporter of stick banging. Stick banging gets pilots into a lot of trouble. Everything one might learn is from the school of hard Knox. Slamming sticks into corners may offer some fun, but there isn't a single maneuver that is done that way. Not even snaps, tumbles, spins, etc are banged. Everything is precisely controlled. If you ever watch an experienced pilot tumble, snap or spin, you'll notice that everything is very precisely controlled. I guess it all depends upon what yer after. If you just want to bore holes in the sky, bang away. If you actually want to learn a maneuver, don't bang.

On a side note: A trainer will not Lomcevak nor will the 40 sized CAP. In fact even my 35% really doesn't have enough gyroscopic precession to Lomcevak well, but it's close. Lomcevaks require precession caused by the rotational inertia of the prop. Models have such a small prop inertia that the precession does not occur, hence they don't Lomcevak. Technically, there are five types of Lomcevaks. The most common involves entering inverted with three end over end tumbles with each tumble rotated 45 degrees due to precession. In other words, a Lomcevak is a precision maneuver... anything else is just stick banging.

It is best to learn spins, tumbles, well anything for that matter from an experienced pilot. You ALWAYS need to know how to recover from a maneuver BEFORE you try the maneuver. Now you probably don't need a buddy system or anything like that. Just have an experienced flyer coach durning the maneuver or perhaps hand over the TX and have the experienced pilot fly the maneuver on your plane a few times explaining what they are doing at each step. I guarantee you'll learn twice as fast with an experienced pilot compared to stick banging... not to mention your plane has a better chance of surviving.

I've seen many spin trainers into the ground. While it is true that most trainers will exit spins if you release stick, you can get a semi-stable flat spin in trainers that don't exit quickly if you release the sticks. To make matters worse, if the pilot doesn't know the proper recovery, they can yank wrong side elevator, or forget to release rudder, and in they go. Many panic and forget to release the stick... this is where an experienced spotter will help as they can belt out "RELEASE THE STICKS!"

I recently saw a young pilot at my field that refuses help and likes to stick bang. He pulled too much elevator in a turn, stalled and entered a spin. I could see him panic, slapping sticks all over the place. At one point he actually reversed spin direction and eventually flipped from right side up to an inverted spin which was really kinda cool, but unfortunally the plane crashed inverted. After crahsing, he announced his TX or RX wasn't working... ha, yeah right. Sad part is that even after the crash he learned nothing.

Cheers
