some POH say no sideslip with flaps, so don't do any sideslip if POH says so.

regarding the spins: why do you want spin an aircraft???

you plane will get out 99% of the spin, and the 1% you will discover you are too low.

Many experienced aerobatic pilots have crashed in spin approved planes, so just don't spin!

just fly safe, ok? don't push your limit, and don't experience things and please NO SPIN without an experimented flight instructor on board...
