Good plane choices. For your first build help yourself by buying the speedbuild kit. The small extras like control rods, firewall etc and the fact it’s perfectly cut already will help you get flying.
My only caution about the mini scout is that it’s only 3 channel, where the TT can be a 2ch glider, a three channel powered trainer and a four channel trainer.
The electronics side is fairly easy, you can buy cheap 5-9g servos and a servo tester to get building, then add the rest after the main build is done, since the receiver, motor and battery all go in through the front. You then don’t need the transmitter or receiver to get the build done, they are expensive and waiting to buy a better transmitter (you don’t need a $300 set up to get going) will pay dividends later. Waiting before buying also gives you time to research what you like and which TX to buy, which is a complex subject.
The tester allows you to centre the servos before you put them in the fuselage and can be used to test the control surface movements when you are done, all for $6 or less, plus they can run off 4AA batteries.
