What radio gear from Hobby King for a 20 inch (40 cm) Cessna 180 type model?
I have been looking for radio gear for a first model,
For example this model: http://www.rcgroups.com/forums/showthread.php?t=841748
So far I have located the following on the Hobby King web site:
TX and RX
HobbyKing 2.4Ghz 6Ch Tx & Rx V2 (Mode 2)(THROTTLE ON THE LEFT)
Servos: Hobby King 3.7g / .4kg / .10sec Micro Servo
What battery ESC and motor should I use? :popcorn:
GWS 5030 or 6030 prop
Plush 6A ESC
350/360 2S battery
Thanks but I need more specifics. Is this ok?
C1818 Micro brushless Outrunner 3500kv (9g) $9.99 9g
TURNIGY Plush 10amp 9gram Speed Controller
GWS EP Propeller (DD-5030 127x76mm) (6pcs/set)
Rhino 360mAh 2S 7.4v 20C Lipoly Pack
that speed control is overkill. the turnigy plush 6amp is plenty. and the hxt 5gram motor is also great.

Is it 20 inch or 40 cm?
20 inches is 50.8 cm, its quite a difference at this scale.
20 inch, 50 cm careless again, sorry
UNGN, thanks for the updated links, nice motor and esc, nice price
Just to confirm the charger: http://www.hobbyking.com/hobbyking/s...idProduct=7637
I can use my own dc adapter? Any concerns about the quality of the DC output - noise, voltage fluctuations etc?
I use a DC power supply from an external hard drive. As long as you don't try to charge batteries at an Amp-hr rate greater than the power supply, you'll be fine.
This is only a concern with really large batteries.
Thanks. The Hobby King receiver weighs 13g according to this:
Whatever I get, weight has to be within the ranges specified below for trainers. Or I could calculate wing cubic loading of a model that flies slowly enough.
The Cessna 170 at the bottom of the page weighs in at 86g and has a span of 24 inches. Assuming a wing area of 24 x 4 = 96 inches and the weight of 3 ounces, plugging it into the calculator below gives a cubic loading of 5.5 and wing loading of 4.5 oz per sq in / 13.5 oz per sq dm and it flies slowly. Keeping this cubic loading for my model should give the same sort of slow flight.
