OK, a newbie here with what's probably a no-brainer for you guys who've been into electric planes for a while. Me, it's been 25 or so years since I was into RC, then with the glow engines.
I've been flying a HobbyZone SuperCub LP recently, getting back into RC planes. No problems, plenty of power, and I've been able to get it up and back down with only minor incidents, getting better thanks to practice and FMS!
I had a friend pick up a Harbor Freight Cub for me recently, powered by a brushed motor turning a 7X2 prop, and an 8.4 volt 600 mah nimh battery pack. It's about a 38" wingspan and around 16 ounces or so AUW. I've replaced the receiver with an AR6200 that came with my Spektrum 6 channel in order to rid myself of the weird transmitter that came with the Cub, and was about to upgrade the power system to the following:
Motor: Turnigy TR 28-26 1650 KV Brushless Outrunner
Battery: Turnigy 1300 mah 3S 20C Lipo pack
ESC: Turnigy AE-25A Brushless ESC
And, planned on running a 7X4 Prop with this setup. I'm pretty sure this would work, my AUW will be somewhere around 16-18 ounces with this as I'm figuring.
But, I'm also wondering if merely upgrading the ESC with a $5.00 brushed ESC from Turnigy, a Prop upgrade to about a 7x4, and a 11.4 Volt Lipo battery with 800 to 1,000 mah capacity would also be satisfactory, at a lesser cost. I'm not interested in enough power for stunt flying or being able to go "vertical", just getting safely off the ground and flying around at cruising speed. But, I am interested in getting enough power to the system to eliminate the stalls experienced by a lot of folks before flying speed is reached when hand launching.
Any thoughts and/or suggestions are appreciated.
