hey everyone, thanks for all the comments, all your post have been so great that my eyes are much more open of what a giant scale airplane involve, to be honest, im more happy and excited about this project. Today i was at my shop working almost full time, in my short free time i went to all the internet webpages searching around about reviews of airplanes. When i saw one that too my attention a lot.
I was reading almost for 2 hours after my dinner about the Wildharerc Edge 540T, a lot of great reviews and videos. Maybe is not a valid to compare my AW 46-60 Edge 540 with a Giant Scale but i really like how the leading wing edge of this airplane helps to make the approach and landings so easy with or without wind. As i said, dont know if the desing in a Giant bird does to same thing than small one but i think in general it does. Also i really like the colors and canopy of the WH Edge 84'', very good price compared of the AW Edge with cost almost $700. Maybe it worth it but for now i need to take care my wallet to invest money in good electronics.
The idea or the Engine is clear, i will get the DLE55cc from authorized dealer to have someone good in future repairs or service. About the Servos, i think i will get the 7955 for the rudder, aileron, elevator and Or should i go with the 7985?. On the throttle some people says that is not good to have digital servos there due the vibration. let me know if that is a good option or maybe other one. Some one told me a lot of good things about Power HD DS120 servos.... which is getting my attention cause is 1/3 of hitec price. Any comment will be great about it.
About the battery, i saw a great value from Tom and Wild Hare RC, complet A123 set with charger for $139. So i think i will go with that...seems to be cheaper than invest on a regulator plus lipo batteries.
One question is.. what is a ''kill switch''?.
If you have the money for the 7955' I would recommend them. The vibration on the gas motors is much higher than a nitro model and much harder on servo gears. You will most likely never have to replace the gears on the 7955 where as the 7985 you probably will. The bulletproof gear train and the ability to run on unregulated 2 cell lipo power of the 7955 is why I run them. Not to mention that if and when you decide to move up to 100cc you can take the servos with you and put them in the new plane where the 7985's would be underrated for most applications.
I've been using a standard digital on throttle for years without any problems. Just make sure you disconnect but do not remove the throttle spring on the carb. I tend to stay away from the hitec brand unless they are the 59xx or 79xx series so for my throttle servos I've been using standard jr digitals.
Like the other guys have said, an ignition kill is also a VERY good investment. I've had to use mine on 3 occasions, all three would have been PITA's but with the throttle kill you just line the plane up on final and hit the switch at the right time. I have used both the 42% products and the Smart-Fly units and I prefer the Smart-Fly just because the configuration makes it a little easier to work into your particular application. They both work equally well and do the same thing.
