Airplane:
Dont know anything about brands...in giant scale area i just saw Aeroworks 260 50CC on my field and looks amazing, thats exactly the size that i want. Im new on 3D with this size of airplanes so it can be something to start.
WildHare, Aeroworks, SD Models, several others...all make quality aircraft.
As a recommendation, while I would not steer anyone away from the brands mentioned above, i can tell you first hand that Wildhare sells EXCEPTIONAL airframes, and offers service and support that is second to none. You will not be disappointed if you do business with them.
As for the airframes themselves, though you'll surely find much discussion and debate on this issue, it seems that the following is generally true:
Yaks tend to LOVE to knife edge.
Extras ADORE tumbling
Edges are the kings of high alpha/high AoA
Motor:
A few people are telling me about DLE 55CC, is a good option or something else?
I've owned a DL-50 (the predecessor to the DLE 55), and currently fly a DLE 111 in my WildHare Edge. Both were/are excellent performers at a very attractive price. i DO highly recommend purchasing a DL/DLE from an authorized dealer in the states. You can definitely find them cheaper on Fleabay, but the authorized dealers can and do provide excellent support. Again, I can highly recommend WildHare here.
You also can't go wrong with a DA product. Their support is also legendary, though you will pay more for the motor.
Finally, for 50cc aircraft, do not overlook the Zenoah G-62 option. A gentleman by the name of Ralph Cunningham at RC Ignitions can convert them to electronic ignition, lighten them significantly, and send you back a true HORSE of a motor. They run forever, never seem to break, and can be found pretty inexpensively. I've owned no less than 3 of them, and adored every one.
Servos:
i didnt know that this high torq engines are so expencive!!!, i was thinking on the 5645MG, 7955TG hitec and use manual choke. (most of my airplanes has Futaba 3004, 3305 servos)
As Jim said above...servos are largely personal preference. Just make sure to meet or exceed the minimum torque requirements asked for by the manufacturer.
He is right, however...do NOT try to save a few bucks here. Buy high quality, well built servos. Even if they cost more, in the long run, you're looking at a $1500 or so investment in an airplane...why risk it to a cheap servo just to save a few bucks?
One note here...there is a "new" line of high torque servos called "HD Power" servos. They are CONSIDERABLY less expensive than most of the other options out there, and seem to be just right for the 50-85cc class of airplanes. While i can not speak from personal experience, they seem to be getting good field reviews, and are beginning to be carried by some reputable RC companies (such as Wildhare, again) that are known not to sell garbage. Worth considering.
Battery:
here is where im lost...........a lot of people is telling me about regulators, lipos, A123.!!!! i know i need one for the ignition system... which one??? for the rx?. It will be amazing if you can number whats the parts i need to fly the new toy soon.
You'll get a dozen different answers here, to be sure. But in general, here's the things to keep in mind:
50cc and larger airplanes draw SIGNIFICANTLY more current to [pwer all those big servos than your .40-.60 sized planes do...you need to be able to reliably meet those demands. As a result, I recommend not using ANY sort of nickel pack (NiCd or NiMh) on the Rx...instead use LiPo/LiIon or A123 packs.
This forum is full of various discussions on the merits of each. be aware, however, that GENERALLY you'll probably need a regulator with LiPo pack(s), and NOT need one with A123's. there are, of course, exceptions to both cases.
On the ignition, I happen to prefer a regulated 2 cell LiPo, but plenty run 4-5cell NiCd or NiMh packs with no issues. IMO, the smaller nickel packs tend not to handle the current demands of an ignition as well, but again...just personal preference.
Do i missing something else???
Probably the single biggest thing you can do for your best chance at success is:
TAKE
YOUR
TIME
Big gassers are a new world from the smaller glow sized airplanes. They vibrate more (a LOT more), they have higher demands for current to servos and other electronics, they introduce an ignition for the motor, they produce interference for 72MhZ systems, etc etc etc.
Take your time with the setup. By this, i mean consider the following sorts of things:
When running servo leads...keep them neat, clean, and organized. Consider getting some crimpers and making your own extensions, to get the right length. Use high quality heavy duty extensions.
Clamp, heat shrink, or otherwise secure EVERy servo-extension connection.
Route fuel and smoke tubing cleanly, and secure it in place.
Use heavy duty switches and battery connections.
Mount things like receivers, regulators, etc securely. Mount them on or in foam rubber. Strap them down well using zip ties, velcro straps, etc. Fuel tubing over zip ties will keep them from chaffing.
Basically, just take your time, and get things RIGHT...every time, every connection, every cable. When you've got 15-20 lbs of $1500+ airplane up there, you do NOT want to be wondering if that $6 cheap extension might come unplugged from the elevator servo, ya know? It'll take longer and cost a bit more to set the airplane up well, but it WILL reward you for your attention to detail and high quality.
===============
Last but not least...ENJOY IT! Bigger really does fly better...let's face it, there's a reason manufacturers like to say their small airplanes "fly like a much bigger airplane".
