I learned the hard way too........... have a GMS120 that dead sticks on me alot. as soon as the engine dies push the nose down and get some air speed OR DIE. I was at about 40 feet and only had 1/3 power and was butterflying the gas to try to get the engine back....then cough cough ....engine stopage.... I tried to drop the nose and bank towards the field but got the CAP SNAP and it was all over. Plane is repairable I'm not even going to take off unless I'm sure the engine is right!!.

CAPS glide like rocks with wings.
