Theory and knowledge before starting in something.

       Remove this ad - become a site supporter!
I am becoming less doubtful of electric planes after I say a fellow flier at our club doing vertical take-offs with an electric Kadet.
My dream would be to build and fly a P-38 but I would not chance a gas engine... one quits and your plane is a collection of toothpicks.
So, Hobby Lobby sells an electric P-38 but... I know nothing about motors, batteries, etc.
A lot of people tell me there is no book up-to-date on the subject since it changes very fast, specially in the last few years.
I don;t like to get into something unless I have a fair knowledge of the subject.
So, question, people: where do I get info on motors (brushless, coreless, different brands, power output, etc.), speed controllers, props, amps, batteries, chargers and the meaning of life?
H E L P ! ! ! ! !
Once my hands and knees stop shaking I take the planes out of the car.

Start here and ask lots of questions.

I would start small with a project like this... say two GWS power units and a couple Li-Poly packs.

Hi Albert:
To get a feel for electrics and have a lot of fun pick yourself up a GWS Slow
Stick (around $60.00) 2, 600MAH 7 cell Nicad packs (the SS needs the extra weight for less than calm conditions) a Speed 400 size BEC Speed Contol (there are tons of models on the market for Speed 400's) A GWS Peak Charger (or equivilent) and finally your choice of a small receiver and servos. The servos don't have to be really small(Hitec S-81) because again you can use them for your P-38 or other Speed 400 model.
The P-38 kit that Hobby Lobby sells fly's very well with Speed 400 motors, if you want to spend the extra money (lot's!) power it with Brushless. The kit is also available from AJ Hobbies in Unionville, Ont; or Great Hobbies in PEI.

If you are an experienced flier, there is no need to start with a small park flier. However, you have the right idea about getting some knowledge first. I would recommend finding an airfield to visit where there are electric fliers and look at what is works. Ask lots of questions.

My first electric was an 8' span Senior Telmaster. Because it flew on a gas .60, I was just going to drop in a cobalt 60. It does't work quite that simple. After about a year of research I ended up with a cobalt 40 with a super box spinning a 17 X 10 APC. Flies great!

You don't have to take a year like I did, but my point is to do the research then dive into the project you want. Another byproduct of doing your homework: you may end up making friends with a realy great bunch of guys, I know I did.

Another good place to check out is Ezone. Friend of mine is playing with lith-poly batts in a 24 in. plane. 2/3ds the weight of nickle hydryd 3 times the motor run. 34 mins flight time. Fully aerobatic. A sign of things to come?

I have been flying & building RC aircraft since 1974, including everything from Scale ducted fans to Scratch -built 1/3 Scale gas. Right now I am having more fun with Parkflyers than anything else. Easy, cheap , quiet and relaxing. I also have built two twin and a few WW2 Scale electrics all powered by cheap, can, motors.
Great bang for the buck!
