Hi All.

Just building Phoenix 50cc aircraft, just wondering what servos you would use on wings, ailerons and rudder??

The manual should tell you the torque requirement, and it's up to you if you want to spend the money for the extra precision and holding power of digital servos. Metal gears probably aren't necessary since this isn't an aerobat that you'll be flying hard.

Remember that Digital draw a LOT more power than analog servos.

At full stall, at power up, or under certain circumstances Digital servos can pull 2 amps each!

Were you to use digials all around ( not necessary even if you use digitals for the major surfaces ) you would ideally need an 18A capable power source...

I've seen a lot of "unexplained crashes" occur because the owner used an undersized 3-5A SmartFly regulator with 8 digital servos, when they really needed something more robust.

This is not to knock digital servos... just make sure you provide adecuate power no matter what you use.

I see too many people grossly underestimating power requirements.

In actual use servos may only draw 300-700mA in normal use, but it's those momentary high voltage draw peaks that kill your plane.

Find some decent analogs. Just match the torque requirements up with what the manual specs for. Dont worry about how fast the servo is either, its a warbird, not a stunt plane.

hey guys.

thanks for the advice.

ive read all through the manual, and there are no torque requirements in there.

what have people used in simialr size mustangs???.

My Feedback: (65)

Hitec 645 metal gear servo's are very popular in 50cc warbirds. Around 30 bucksapiece

I like the idea of the DLE55RA ([link]http://www.dle-engines.com/dleg0455.html[/link]), rear mount muffler and a angled plug would allow for a better chance for completely hiding of the motor inside the cowl without hacking on the cowl - even more so when you take into account the muffler is on the back, and there is no 'wrap around' part of the muffler to rub on the narrow part of the cowl at the front - the pitts muffler on my H9 '60' sized with a DLE20 caused me to cut the cowl to get it in on the side of the plane ....... Grrrrrrrrrrrr
