As others have mentioned, the A-10 COULD be a first plane for you; however, it's got a few things that make it a bit more challenging for first time fliers - differential thrust, and a low wing, give it different flight characteristics than those of say, the Bushwacker or Simple Cub. Does that mean that you CAN'T make it your first plane?
No.
I was like
@Horseman3381 - I started with the Sea Duck as well, as my first build. However, I'd had a lot of flight time with quadcopters on a simulator, and then time flying our club trainers, which were Apprentices. I was fairly comfortable before I put my Sea Duck up on the first flight, and had a club member maiden it for me and trim it out, before I started flying it.
It had its quirks, and flew differently than the Apprentice. Was it a good first plane? For someone who was used to flying 4 channel, YES. If you've not had experience with using rudder/differential thrust/yaw to turn a plane? I wouldn't recommend it. and since the A-10 uses a lot of those same principles to turn, you'll encounter similar characteristics. In addition, the low wing (one mounted under the fuselage, as commonly seen on the warbirds or racers, as opposed to a high wing, common in Cubs, the Bushwacker, Tiny Trainer, etc) wants to have a bit more speed over the wing to keep it aloft, meaning your reaction times have to be a little sharper. Now, that might not be an issue for you, but if you ARE teaching yourself to fly and are still trying to get used to things like "left is right and right is left" when the plane is coming at you, then you might want a plane that's more forgiving and will fly a little slower.
