I watched your video and I found out that your Cessna was not getting enough air speed prior to take-off. Your left banking might be the reaction from your propeller and the air passing to your aileron is not enough to counter this roll. Your airplane is in stall state. Its very hard to control this plane when it is in stall state.
The first thing is to check your rpm and thrust base on specification of your motor. My airplane is already upgraded as you can see on its latest video and Im also using 4-stroke O.S. FS-70. Your engine is above the minimum required size, so check engine carburetors settings. Second, check your wheels and runway for some drag. I changed all the original wheels to 3-inches Ø so I can take-off on most grassy runway.
I notice your nose gear is also too high, it can cause you to drag your speed acceleration and get airborne earlier, so correct it. This plane should take-off without pulling the elevator stick when you reach the take-off speed at half-flaps. On your next take-off, try to keep it on up-wind direction with constant full power until you reach enough altitude before you retract your flaps and make a turn.
Trim your control on safe altitude at half throttle. Find out the stall speed and make sure you maintain above that speed special turning or banking. This airplane has higher stall speed because of the high wing loading so use your flaps if needed specially landing on low wind to slow down the touchdown.
Your CG is correct based on specs. My Cessna has 12x8 Propeller and same CG of 70mm. On your test flight, try to take-off on smooth and longer runway.

Hi guys, I'm building this model and someone told me to replace the nose landing gear and to glue the wings.
Do you have the same opinion?

I bought a J-3 RC plane but could never land it. Fortunately for my passengers I don't have the same problem in full scale aircraft.

wow how do you idle the engine that low without it cutting? how much does this camera cost?

you should fly into an airport pattern and report 4723poppa for landing see what they say

yeah i have 3 inches wheels and a 4 stroke thunder tiger 75, whit a 13x6 propeller
i think than the problem was the CG,
in the owners manual says than it is at 68mm to 73mm i put the CG at 70mm
i need to know were is th reeal CG
