Conversion Combo Kit for 30-35CC Gasoline Airplane Converted to Electric Airplane, yet the best Conversion component now Exclusive Sale on sdshobby.net

Why Converted model with gas engines to electric motors?
*There are a lot more kits designed for gas power than for electric power. Face it！
*Nearly any gas plane can be converted to electric power effectively. That’s Fine！
*There are many pilot have been flying and building radio controlled airplanes, helicopters, boats and cars for near half life. I have been specifically building and flying electric airplanes for over 10 years. Latest interest, follow it！
*This has been more realistic to do lately because of the huge leap in battery technology and it has been a very fun way to still make balsa kit planes from scratch, but not worry about any gas problems. Trust it！

Here's an idea of what to look for:
Type of plane: Any plane with 'plenty of wing' makes an excellent choice for conversion since the wing loading will still be reasonable even if the plane turns out a little heavy. If the plane will fly at high speeds (i.e. a sport-aerobatic design or pylon racer), a low drag design is desirable. Simply put, an effective electric plane is one that flies nicely at 1/3 to 1/2 throttles.
Type of construction: Most gas planes are hideously overbuilt. Many popular 'easy to build' kits make use of heavy plywood fuselage sides etc where it is not needed or wanted in an electric. Some kit designs are better than others.
If you have a basic understanding of how model planes work, this process is straightforward. It is important that you understand the basics of power-to-weight ratios and balance points




It's obviously can sure that there are some Gasoline Airplane excellent choice for conversion, one of them is the classical sbach 30-35CC Gasoline airplanes, and sdshobby make a another deal for rc model enthusiast-- Conversion Combo Kit for 30-35CC Gasoline Airplane Sbach Series Converted to Electric Airplane ]]> R/C Blogs Alanalice http://www.crackroll.com/forums/showthread.php?t=3559 <![CDATA[For Sale Discount Opto Gas Engine Kill Switch [SDSHOBBY:GE3001]- US$9.57]]> http://www.crackroll.com/forums/showthread.php?t=3558&goto=newpost Thu, 17 May 2012 06:12:57 GMT *Opto Gas Engine Kill Switch*- This device allows you to safely and remotely kill your electronic ignition equipped engine your transmitter.igniton...

The folks at CCRC put on a great event each year, and their field is top notch! There is usually food and drink available at the club house, and the usual door prizes and raffles. Previous years have seen heli contests held throughout the day, including auto rotation, drag race, guess the time, and precision landing, and I'm sure this year will be no different! They have a great runway and a seperate heli area with exclusive use of both throughout the day.

    So if you find yourself close to Greensboro, NC this Saturday, stop on by and hang out with a great group of guys!

    Stock motor and ESC
    HS-5245MG cyclic servos
    Futaba S9252 tail servo
    CY tail blades
    TT driven tail

    All you need is a battery, reciever and radio and you'll be in the air. Canopy has some small cracks on the bottom but is in overall good condition. Please feel free to ask questions. I paid $560 from the RCG member I bought it from and have not flown it, so I think $530 would be more than fair but I am open to offers. Thanks for looking.
