My plan is not to balance the motor or screw, but remove the fan, on some planes I've read here in the forums that the motor would not even rev to its potential because of vibration. I was impressed how a guy on youtube balance a very poorly manufactured fan and afterwards the plane had an entirely different sound, he also claimed an increase in performance.
Yes it was a rtf, my mistake, it hasn't taken me long to realized, I should have perchased a kit and built it up with more quality parts, so here I am. Not sure how much of the add is accurate. I purchased it off an Ebay site, add listed a 4000kv inrunner, but is actually a 4300 outrunner, add list a 1500mah 11.1 3s, but battery is black without any numbers to be found, so that I am unsure now, I don't have a small scale to measure the weight, that might help me match the size. Do most kits or arf come with 2200. I'll try to look into this on my end alittle more. (Yes about the 2200's, I found that).Thanks folks.
Complete Kit, Ready to Fly, Easy to Assemble
Specification:

Wingspan: 780mm (30")
Length: 880(34")
Flying Weight: 610g (21 oz)
Ducted fan:EDF-D64mm
Drive System: 2040/4000KV inrunner brushless motor(max thrust: 500g)
Servo: 3X 9g high speed micro servos
ESC: 30A Brushless ESC
Battery: 11.1V/1500mAh 15C Li-Po
Control system: 2.4G 6-Channel proportional radio control system
Radio Control Range: 2000 feet (600m)

My bad, I tried several times to buy off of hobby king but never figured out the shipping, so this was the best deal to my place in Canada. My Cessna is coming from HK, as well as my additional parts. I guess "Mediatoys" put in a battery and a controller. Hmm. I don't really like it when I get the one of a kind deals, haha. Oh Well..

Sounds like you got a different version of the plane. Maybe this one? This is available kit-only from HK (no battery, motor, ESC, etc), sounds like your Canadian dealer added his own parts.

Hmm. very odd Fredmdbud, I have no idea about this one. I just went and checked the box... And its a nice box, all professional and mass produced looking. All the items I listed above are right off of the cover, all included, Inside, the radio and battery all have their own little storage area. Wierd that the sizes are different 880mm vs 1000 like all the other ones. same 4300 0utrunner. I guess I will purchase atleast 2200 mah batts, maybe a 4s in the future??? Mine has the A on th etail, with the lines cut through the body as per the kit version above. Just notice how different the duct intakes are, top one being more like a true scale version, mines are larger like the lower picture. Didn't think there would b any differences out there but I guess is just one companies vs another.

My first one is the ARF/PNP version with stock 4300kV motor. I would have preferred a lower kV motor, but getting the fan out of the plane was a chore, then I couldn't get the rotor off without stripping the screwhead, so I left it there. I replaced the stock ESC with a Freewing 45A. I'm flying with 4S with no problems, but I go full throttle in bursts less than 10 seconds. At the moment I can't remember how many amps I measured with a wattmeter.

I've got a kit-only for replacement/standby. Might be a while, this plane is very stable and controllable.

Sounds good, I'll just leave the motor as is then, and maybe change it out some day later, I have a 55a w ebc from hobby wing with a card coming for this plane. When you run a 4s, does that mean it's 14.8v, all I see for 11.1v is the 3s's. I searched until I was tired. It seems the Turnigy batteries are pretty affordable and reliable. A kit only backup is a good idea, for 29$, how can you go wrong, it's 7$ for some epoxy, haha. Unfortunately it cost me 40$ to ship any plane to Canada. A not so local Canadian dealer wanted an extra 50$ for the one I bought so Ebay/California was the way to go.
Do you run on a standard cheapy radio??

4S is 14.8V, yes. I'm using a Spektrum DX7 radio, but a "cheapy radio" should work, as long as you know it's good (e.g. range tested, etc).

So, can one conclude that a 2200 4s 14.8v is going to be more powerful than a 2200 3s 11.1v.
How to these motors hold up when the voltage is increased as such.
Experience speaking, would you go with a larger 11.1v, say a 3000 mah or just go 4s 14.8v and call it a day. I would guess that when similar mah are compared the higher 4s may just last longer with flight time??

In answer to your first question, yes a 2200 4s 14.8 volt will give more power than the 2200 11.1 volt 3s 11.1 v battery, that's the easy part to work out, you have an additional 3.7 volts being delivered. 2200mah is just the capacity. It is feasible that you will get extended flying time with the 14.8 volt pack because you will be able to maintain flight at lower throttle settings, however things are not always that simple. This is a subject that has been covered extensively within this forum so a search would reveal all, you will be bombarded with some very scientific answers.

The motor in the HK 64mm T45 will handle 4 cells without issue, but you have already posted that yours is not the HK T45 thus rendering your second question unanswerable. If you could post pics of what exactly you have then maybe I/we could be more helpful.

haha, FUN! - next, more high speed low passes.

on a side note, my rotor (collet adaptor) pulled free yesterday spooling up on 5s.
time to break out the red loctite.

Cool Dave... We will get closer together next time, I was probably a bit too far in front most of that flight... my reverse camera view was pointing too low to pick yours up for most of it unfortunately... I like it when both Hawks came into view though!
Definitely something to work on!

I had to wait until I got home to watch it properly. Classic. Have a look at around 1:16 when the you lose picture then when it cuts back in it looks like a missile has gone by you and you can see the smoke trail.
I can still remember Nitro calling out "where am I, where am I" when you lost picture for that split second.

That was a long flight. What battery you using?
