Well the Mini Guinea uses two motors, so that’s out.
You could definitely build many of the larger minis with a 2212, but they would just be heavier and more difficult to fly. The size of the battery is a big factor too. If your 3s lipo is a 2200mah, then I definitely would not recommend doing a mini. You could fly it, but it wouldn’t be easy.
With that motor and ESC combo, why are you looking at minis? If you’re in it for the 250g limit, then that motor and battery will probably put you over the limit anyways. If you’re not in it for the limit, then how about looking at a slightly smaller swappable? The wing span of a Scout (normal variety, not mini) is only 2” motor than the Mini Guinea and is made for your motor.
Also, what is the kv of your motor? Most of the full size ones prefer a 1000kv, although 1400kv or 2200kv would still work.
Im building a mini because i dont want a big plane. Hard to carry around. I have 2 2212 1400kv with 2 30aesc. I was looking into the mini guinea cuz i like the shape. Tho idk if i can power them using only 1 lipo. I also like the mustang build. But it's too big for my liking

What I was trying to say was that some of the minis aren’t that mini. The Mini Guinea has a wingspan of 35”. In comparison, a Baby Blender (not mini) has a wingspan of 24”. A Bloody Baron is 29”. The reason I bring those up is that they are made for the B pack sized motor that you have. If you’re looking for compact, then having a removable wing might be necessary. The Cub is an option in that case, although it has a 38” wing.
However, you could totally put your motor on a mini, it would just be heavier and not fly quite as well. You may also need to add tail weight to get the COG right, since the a B pack would be adding more weight to the nose. Good luck and post pictures!
It will likely work. But you will need to be a very experienced pilot to fly it. If you are learning to fly, you will need a beginner friendly plane like the Tiny Trainer.
Larger planes are easier to fly.

The Mini Mustang is designed for the A pack, so putting the B pack on there will make it heavy.
It’s ok for the prop to turn either direction. Conventionally, the prop spins counter clockwise when facing from the front, but there’s nothing in the design that requires that. However, the prop nut should thread on the opposite direction of the prop so that the motor doesn’t unscrew it. Most motors have a clockwise thread to fit the counter clockwise prop convention. If you have the wrong direction thread, make sure to snug it down extra tight, and maybe use some loc-tite.
A 5045x3 is kind of small for that motor but will probably work.
I’m not familiar with magic board, that must be specific to your country/region. In the United States we use the product called Adams Redi-board. It’s about 4.5mm thick with paper on each side, and a 20x30” sheet weighs about 110g. Be especially careful not to use a heavier foam board. This is the most common mistake that first time builders make. If you use a foam board that’s twice as heavy, plus your already heavy motor, then your plane probably won’t be able to fly.

ive used a similar extruded polystyrene foam board like the adams, it breaks so easilly, a rough landing can break the wings and fuselage.

this is an example of magic board, its dont break easilly when bent, but ive never used it beforeHEE WING Hunter F22 400mm Wingspan MPP PP Foam Magic Board RC Airplane ARF

DTFB will bend and crush, but usually doesn’t break, except in a particularly severe crash. Other varieties, such as the stuff sold at WalMart are more brittle and snap more easily. Some people use depron, which might be similar to what you’re talking about. It’s really good, but not as rigid as DTFB, so you have to reinforce it with carbon fiber strips.
My recommendation to you is to do one plane according to plans first. If you decide to make a small plane with a large motor and extra heavy foam board, you’re making it unnecessarily difficult on yourself.

Dear novice modeler.1. You asked - You were answered by experienced modelers. You do not understand what they advise you and persistently say your own - I WANT! 2. If you want to make a mini model, make a pigeon out of paper and when you're done playing and you're ready, make a Cessna with a 1 m span. Your engine-regulator kit is suitable for this model-desk for novice pilots. YouTube is full of videos with drawings. I have 4 Cessna 150 in the hangar according to different drawings with an engine 2212 . With a 2S battery, she walks through the sky on foot, with a 3S battery, she performs aerobatics.If you stick tape on a foam board and iron it with an iron, a miracle will happen: the board will become very durable and beautiful.
