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:

http://www.rc-radiocontrol.com/hobby...eceiver-6ch-v2

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.
