Andre Kilian on speed controllers

I have found the Jeti range of speed controllers the best value for money, and no interference problems (Christo had a 30A Advance available at R550 - they retail overseas for about $80).

Some bad reports have been circulating on Castle Creations speed controllers, but the latest ones seem to have the glitching problem sorted out.

The Model Motors controllers (TMM) that Jonathan Spratley is importing are excellent, but the prices are a bit steep.

I have also tried the new Hyperion speed controllers (will be available from Cape Sailplanes shortly) and found them to be excellent - I am using one in my T-Rex.

The Align 35A controller imported by Aerial Concepts are also very reliable, and I like the heat sink attached. Makes a lot of sense if you are using 4 sub-micro servos, which puts a lot of pressure on the BEC.

There are a number of el-cheapos available locally, but I would not even touch them with a long stick. If you try a handful you may find one or two that works well, but I would not risk it in any of my planes (well, maybe in an old Shock Flyer.)

Even some of the premium brands like Aveox had teething problems - excellent service, but after losing 2 planes and having one on fire, you tend to become wary. Must admit though, the Easy Street catching fire in the air was very impressive - the separate battery pack that I had on board saved the day...
