It's a great flying airplane, had one for several years. Mine too was without flaps. On the takeoff keep the climbout shallow to build your speed. Get gear up quickly. Inflight it's a real peach, no bad habits and the T-33 has the prettiest aileron roll ever seen. Landing is where you will earn your money. Dont get slow as it will snap. It would be a good idea to get some altitude on your early flights and slow fly it and stall it just to be familiar with the characteristics. It recovers from the stall quickly but loses quite a bit of altitude when the nose drops. It spins beautifully and recovers quickly. The approach should be flown with a slight bit of power and a little more shallow than an airplane with flaps. Try to fly it to the runway and pull the power about 2-3 feet. Too slow it will drop a wing, too fast it will bounce then drop a wing. Keep your speed brakes out to allow a little more power and help kill the speed. It will be a good idea to keep a few spare landing gear parts as I needed quite a few of them along the way. You will really enjoy your T-33, it's a beautiful airplane.
