EGO (Art-Tech) Cessna 182
My first four-channel plane is still in service - an Art-tech Cessna 182 (distributed as EGO in Australia). This is a 1m wingspan four-channel foamie, and seems moderately good value.
So far, I have 2:06 flight time and 20 flights on the clock. Bearing in mind that my opinions depend heavily on my own RC flying background, here's what I think the pros & cons of this plane are:
Relatively inexpensive. I bought this for AUD$275 RTF, which is a very decent price. I actually had a $500 budget, however I really wanted a DX6i, so I decided to buy a cheap RTF plane, ditch the receiver and replace it with the Spektrum DSM2 gear. The RTF transmitter and receiver I sold on ebay for $50, so the plane ended up being a ~$225 ARF. For something that wasn't a planned purchase (I didn't heavily research planes at all) it worked out not too badly. The cost of the plane + radio ended up less than any RTF which included Spektrum gear that I could find retail.
Stall. Doesn't tip stall, just mushes over. Makes for very unexciting landings, which is great.
Flight Time. Does 14 minute flights easily, put-putting around on half throttle with occasional full throttle aerobatics. I've timed the motor at 21 minutes running at half throttle, however I don't fly for this length of time.
Flight Characteristics. The aircraft will fly itself out of trouble given enough room. This makes for relaxing circuits and docile landing approaches.
Scale Look. It looks pretty, which has to go some way towards making a guy want to come back to fly it again.
Wind Behaviour. The plane flies well in a little wind and with the rudder throw increased to about midway it will perform a crosswind landing rather nicely - one of the reasons I was adamant to get a four channel plane when I got "back into the hobby"
Stock landing gear. The stock landing gear is great on tarmac, but absolutely horrendous on any grass save a putting green. I replaced mine with 2" Dubro wheels and it's now quite well behaved.
CoG documentation. The ideal COG is not documented at all (the manual is also "interestingly" translated). As a result, it's difficult to establish with confidence exactly where the CoG should be after any modifications.
LVC. My "how long will the battery last" test in the back yard was illuminating. The motor doesn't cut out. It just gradually dies as the ESC draws all the available power. Once it's gone, the servos stop responding. Net result: One very broken foam plane. I therefore run at 66% of my measured maximum time, and as the timer counts down I start paying more attention to how much available power I've left. I'd rather throttle down and land dead stick than try to keep the motor running and retrieve the plane in a plastic bag.
Small wingspan. Compared to something like the Apprentice 15e, the ArtTech model's 96cm wingspan is fairly tiny. The plane will punch through wind fine, but it also gets knocked about a bit by turbulence.
Living With It
- The ESC failed after a little over 7 hours of flight time following what may have been a minor nose-in on landing and corresponding motor stall. After throttle off, the prop was pulsing around slowly and a burning smell could be detected around the plane. Battery was not too hot and down to about 3.75V per cell. My theory is that there is insufficient airflow around the ESC (ie, none), and that running the plane at high throttle settings has cooked the speed controller; the high current of the motor stall has caused damage before the ESC could cut out. Added to the earlier observation that there is apparently no LVC, I'm guessing this is a very low spec ESC. I also wonder if some folks crash their trainers well before 7.25 hours (~29 full charges) and put the failure down to crash damage.
- I replaced the ESC with a $25 30A unit that will use the 2S battery that came with the plane (and allow other options in future). It runs fine.
- The only issue with the plane is my own fault - my handmade nosegear with its quick-release wheel retainer is prone to popping the nosewheel off on a hard landing. Which is probably a benefit, since my other plane strips its nosewheel servo and breaks plastic pieces in the same situation.
- Fixed the issue with the wheel retainers by buying some greatplanes shaft retainers, and taking the plane for a fly - wheels stayed on after quite a few touch-and-gos, so looks like I should have done this a while ago.

Sorry I know this is an old thread but I was thinking to buy this model ( I am a beginner ) . Can you please advise if it is suitable ? I really liked your review and breaking down pro and cons.
I am confused between getting this or a hobbyzone champ 3ch ( which is a totally different class ) I like to start learning on a 4-ch, although not sure if this is a good choice ?!
Any help is appreciated!

With a fair amount of time in the simulator, a calm day and a big place to fly (or, replace any of the above with someone to teach you), then yep, it's fine.
I have a champ as well, and I can only really enjoy flying it when there's no wind - I got this plane to fly on windy days (and there are a lot of them here, it's 25Kts right now).
[I'll add that I haven't updated my blog recently, I've flown it a couple of unlogged flights since, but with hot weather I've not really been keen to be standing out in the sun getting burnt]
