I was practically born with a soldering iron in my hand lol. You'll find a handy (no pun intedned for those who know where I'm going with this) little tool known as a helping hand/third hand. They're like 6 bucks or so and the have a frame with 2 aligator clips and a magnifying glass, which is seldom necessary. You just put the wire in one aligator clip, and the other item in the other, postition them, and then solder, there's really nothing to it. It's as simple as heat, both objects together add solder directly to the objects not the iron, that'll give you a good strong solder joint. It's seems as though you've got a good start though. Ohh, by the way, most soldering irons get a wee bit hotter than that, most closer to 1000 degrees farenheight. I've been singed by the heat gaurds on mine a couple hundred times, lol. The best part is as long as you don't melt whatever your tinkering with, you can always melt off the solder and try again. It's a good skill to have in this hobby. Hope your plane works out well. I'm probably gonna have to hold off on one myself, I promissed myself a new Trex 450 SE heli first, as some may know are a little pricey...
