Default Seagull PC-9 Build advice please

G'Day all.

I'm about to put together a Seagull PC-9 and have read lots of things about these planes, mostly good but a few bad. A lot of the stuff i have read was very old and i believe they have changed a lot of things about them so some of my questions are.

1 Inverted Motor - This will be my first time with an inverted engine i will be using as OS .46 AX (Or i can get a OS .60 if you think it is needed), what precautions do i need to be aware of with this? I've read the fuel tank is mounted to high and i may need a Perry pump what ever that may be. Anything else i need to be aware of?

2 Shaft angle - I have read you "may" need to add down thrust which is what the RCU reviewer did to his, is that still needed?

3 Servos - What servos should i put in this plane? I have also heard that the push rods should be upgraded, is this true?

4 Clevises and control horns - A lot of people have said they upgraded the clevises and control horns? If this is required what do i upgrade them to?

5 Elevator/Rudder "flutter" - I have heard this can be an issue but i have no idea what to do about it?

6 Flaps/Flaperons - I land on quiet a small and pumby grass strip in central Australia, i have plenty of room for approach but need to touch down as slow as possible, i have also upgraded the wheel size on my trainers to help with this, is it worth going to the time and expense to make functioning flaps? If so are there any articles to help with this or are flaperons going to help slow me down enough? I have never used either.

7 Props - I have heard a 3 blade will help with slowing this plane down, have anyone got reccomendations on props? i would rather not use a 3 blade for cost primarily, maybe a square master airscrew prop rather than APC? I'm not looking for a super fast plane just something with plenty of torque that will fly a good knife enge, maybe a 10 X 6?

I know that is a long list but if you have any advice at all for this plane that would be great, i throw my planes around in the air pretty heavily, anything that you think should be upgraded would be greatly appreciated, i'm only new to the hobby and build my planes very slowly with lots of epoxy but that won't help if i'm going to do damage to other parts. Any general advice on building and setup would be great too, do these planes generally balance ok or should i build it tail or nose heavy when positioning batterys and fuel tanks etc.

Thanks in advance
