Yup, some planes don't need them or it may be inadvisable.

On glider type planes, such as this one, they sure are handy sometimes when trying to bring the plane in.

That said, this plane flies SO slowly as it is, methinks that the problem lies not with the plane, but rather a lack of practice with this situation....

Taking it out to an open area and doing stalls and stall landings will probably solve the problem.
