PCM
PCM: Papa, if your concerned about spending $500USD+ on a total setup, don't worry about PCM at this point. It costs a lot more than standard "PPM" or "FM" radio gear.
I think your list is short. You'll probably need a lot more than two props and one glow plug. You have no glow booster. Doubt you can get all the glue you need for $10 CAD... try $30+. Covering for $10? You'll probably need two rolls of covering for a 40 sized trainer - that is about $25USD or $40CAD. Etc, etc, etc.
There is nothing wrong with being frugal. However, when you start cutting corners at the expense of safety (both yours and others) I draw the line. Additionally, going the cheapest route possible almost guarantees you will have equipment issues... kinda takes the fun out of it.
Like I mentioned in another thread you started, I always tell new club members to expect to spend a minimum of $500... that is USD, remember, most of us here are from the States. $500 USD is about $825 CAD. I firmly believe you really need this to get properly started with a glow powered trainer... $500 USD or $825 CAD. Yes, It can be done for less, but you have to start cutting corners to do it for less. It can be done for more too, but I'd say anything over $1,000 is overdoing it. Sheesh - I've only been doing this for six years and my last plane cost $4K.
There are some items that are safety related that you really shouldn't cut corners on, such as some method to check batteries and a good starter. The whole idea behind a chicken stick is demented... I mean sheesh, look at the name "chicken stick." I think you best bet at this point is to spend $20 of your $500 budget and get a beginners book on RC.
