Where was the locktite when I needed it?

I got a chance to fly today. During a 2 year anniversary childrens party we boys escaped from the children and took our 250 racers to the sky. I was rusty, very. Got two batteries flown during the short timeframe but managed three crashes. One knocked the headlights off. The second resulted in a 10 meter free fall after hitting a tree.

Once I found it it turns out the cage had come loose. Three screws were missing and the last one was coming off. But not broken loose. They were unscrewed. Did I not put locktite on them or is my locktite in bad condition. I had problems with bad locktite before, but this time the fault is probably all mine. I usually complete my builds before locktiting them properly. If I'm going to be this absentminded in the future, it might turn out to be a bad practice.

Do not underestimate the effect of vibrations on an RC aircraft. Secure your screws!

Driving and flying at work

For family reasons there hasn't been any building going on since my last post. In fact, the trifecta is still sitting on the bench waiting to be trimmed since the change of ESCs.

But I can't live many days without RC and I spend some time flying micro-quads and driving a car at work. Yes, a car. I had forgotten that even if it it seems simple next to flying helicopters, cars are rather fun as well.

I purchased a WLToys L939 for my 2 year old son. I picked this car because it is cheap, it has a speed setting on the remote to make it go slower, and most importantly; proportional steering.

But he wasn't interested in driving with the remote, even if he understands how it works he wants to drive it with his hands. And so, I took it with me to work instead to enjoy during breaks or while waiting for the compiler to crunch through the code. And it is a success!
