ok first the boring details

after flying a big lift more then 12 years ago
i stopped this wonderfull hobby because of women ( i now i now)

some 4 years ago i picked it up again (devorced) and bought from a hobbyist
who,s eyes where bad (getting old) but a smart man! since his engines where as old and worn out as him ( no offence!) a Big lift , pilatus porter ,etc etc
now the guy was smart , after flying it for the first time i had real poor power from the OS FS 120 . a crash followed ( low altitude)
some how i still had it in me, not to stall the plane while in take off
(i guess the lessons i had 12 years ago still ringed some bells)
damage: landing gear , front and rear
i dropped again the hobby picking it up 4 weeks ago
(new girlfriend but more "giving ;-) i guess the upgrade from 1.0 to girlfriend 3.0 helped ;-)

ok now the FS120 was obsolete since this engine was prodused in ,84
cam shaft worn out so basicly r.i.p. no power anymore

now i ordered a G23 Zenoah after reading and following this amazing forum
included a fema autostart

now here,s the question:

schould the engine be mounted slightly "of"looking to the right??
or just in strait line with the plane?
since i always saw that most smaller engines where a little of
also i flew a cessna 152 ( real plane) and it always wants to go to the right in take off because of the torq
does this means i have to mount the engine a little in that direction?

also since this is a gas engine any suggestions on gas holder ( tank)?

even more: i am a so called slow flyer , so i want to do lots of landings take, offs
do i cary lots of fuel? if so should i move the tank to a more balanced piece in the plane?

where do i measure the balance? 1/3 of the wing , looking from nose to rear?

also would after learning again to : "Fly" adding ailerons and landing flaps make it even more better to control and do real slow landings?

(i have 35 hours lessons ( and solo)on a cessna 152 and using the flaps at 30 degrees makes it really slow in landing and holding the power
and for take off 10 degrees makes it slow but fast lift offs)

thanks for your time

and forgive my bad englisch writing somehow i speak it better
