Default RE: U-Can-Do 3d 46?

Man, I've been reading and reading and reading this thread since the first page for 4 days now and I'm still only around page 80!! There is just a TON of info in here, but I'm to the point where I can't read anymore and just have to go ahead an ask some questions.

I'm still very new to the hobby - on my 1st plane still (Hangar9 P51 trainer), but most people say I've caught on pretty quick. Within my first couple weeks (solo'd 2nd day out) I was doing inverted circuits around the field, snap rolls and plenty of stupid things you shouldn't be doing with a warbird style plane but haven't crashed yet. Long story short, after four months or so of flying the P51 I'm ready to try something else and settled on the U-can-do 46.

I've read hundreds if not thousands of posts about engines in these things, but still need a little push in the right direction from more experienced folk. My goal at first will simply to get the thing flying, but once broken in I want to begin to learn hovering and 3D in the real world instead of the simulator. I bought a .51 TT based on the advice of the LHS, but after reading so much here it seems like it'll be underpowered for what I eventually want. No problem, as fate would have it someone basically gave me an H9 Twist the other day, so I can put the .51 TT in that with my radio / servo gear from the trainer as a backup.

Going back to the LHS, I had it in my mind I wanted to try a 4 stroke no matter what... Saito, here I come! Well, they had a .72, .91 or .100, but not the .82 I was hoping for. I settled for the .91 thinking it would be a much more versatile engine for other planes. Now I'm having a bunch of second thoughts. Did I go way overboard? Is this too much engine for someone on a 2nd plane? Should I take it back and exchange it for the .72? Also, what props do I need for break-in and then after that? Elevation here is about 10' above sea level and I bought 15% CoolPower 4stroke fuel (that's all the LHS had).

I *hate* having to buy things twice, so I usually spend way too much $$ (putting myself in trouble) but getting what I feel is best all around.

Please chime in on some of the other gear I plan on using - this is my first real ARF build:

Radio - JR 9303 Heli (had this a month now - love it. Plan on flying heli's in the future too) Will use the receiver it came with.
Battery - JR 2700MAH 4.8v
Servos - JR811's on everything but rudder / Hitech HS-5645MG on rudder
GP nylon / pinned hinges instead of the CA ones
All the remaining stock gear from GP

Misc questions:

1. What should I expect for flying time with the stock tank on a .91 saito? Should I get something bigger like an 11oz?
2. Where are some good resources for learning to tune 4-strokes?
3. CA hinges seem like they are harder to deal with than the small nylon pinned GP ones. Am I OK to use these or would it be better to stick with CA? I test fitted the GP ones in and while they do slide in with a little pressure, I think I'll need to trim some balsa material for a better fit or should they be "tight"? I plan on 30 min epoxy for them.

I'm pretty nervous about all this and need some thoughts either way.
