I am about to finish my private pilot course and intend to purchase a plane. I noticed the grumman aa-one is a low cost plane. Should i pursue this aircraft or stick wiht what i been training in ??? Cessna and piper pa/28.I also plan to get my multi rating and get a twin down the line and was thinking about having to sell the gruman . should i hold out and go strait for the twin or get the grumman and build up my time in it?
