i've flown a few pushers in the uk and never seemed to have a problem launching..You'll probably find your model has a hand (finger and thumb) grip somewhere underneath around the centre of gravity..If not then a good idea to make one out of a piece of balsa or something. Make sure you give it a bit of a run up (easier if someone else launches for you)..and away it should go.. The only other method i have seen is to use a small wooden ramp and some bungee cable.. Not started flying in Doha yet but keen to get started and am hopefully returning with a couple of brushless electric set ups after my summer hols..
