Yeah, the 2212 is the cheapest motor, and the 9 gram servos are the cheapest servos. If you’re budgeting, I’d suggest switching to one of the B pack planes. Those all use a 2212 1000kv. The Simple Scout is the most popular. So not the 1400kv that you linked, but the 1000kv version which is usually the same price.
If you want really budget electronics for B or C pack planes, check out Valuehobby.com. It’s not as good as the stuff that comes from Flite Test, but it’s very cheap and I’ve had good experiences with them. It’s still generally better than what you can find on Amazon. Specifically, ValueHobby has better servos than Amazon (TowerPro brand), and you can get the rest of your parts there too.
