My wife got me a grandstand ticket to the Red Bull Air Race for my birthday. Went to see it over the weekend not expecting much. I was pleasanty surprised by the end at how much fun it was.

Since I initially thought the race wouldn't be much to watch I decided early on to try to get as close as I could to the runway to take pictures of the planes taking off and landing. It would also mean getting to see the planes up close. I found several guys wandering just outside the fence of the runway and joined them. The runway was directly behind the grandstand seats so it wasn't like I had far to walk. Managed to get several good pictures of the planes taking off and landing but most of the time I got crap pictures due to my carp camera (and on the first day my iPhone).

When the race actually started I regretted being at the runway instead of watching the race. It was actually really cool to watch. It wasn't so much a race but a low flying high speed aerobatic performance disguised as a race. I got some pictures of the race itself and a couple of videos but nothing really good since all I had was a compact camera. After spending some time trying to get good pictures of the race I decided that watching the planes from the tiny LCD screen of my camera wasn't much fun and spent the rest of the time just watching the race.

Sorry, this is unrelated to RC or modelling. Just needed somewhere to host these graphs. Pretty graphs though.

I'll be using this thread to dump pictures of stuff I find interesting. Mostly as reference for when I'm building. For the most part, these are basically my build wish list.

I met up with a couple of guys last weekend who are flying indoor rubber powered planes. I've built some rubber powered planes in the past - a couple of cheap outdoor ARFs (kind of like what Hobbyking now sells) and several scratchbuilt.

I've always used regular rubber bands with my scratchbuilds because it wasn't anything I took seriously. Most of my freeflight planes were and still are gliders. So, the guys "donated" to me several length of TAN rubber and I tried it on a couple of planes I brought along and WOW.. didn't know they could fly like that! One of my planes flew for over 45 seconds! (Now, this is nothing to what the guys flew. They average 3 minutes in the hall. But my plane never flew for more than 10 seconds before!).

So. Now that I'm starting to seriously look into rubber powered flight I find myself in need of a winder. 200+ winds is doable by hand but 1000+? No way! I was planning on buying one but my nearest LHS did not have any. Not wanting to wait any longer I decided to try and see if I can build one.

So here's the result. Sorry, no build pics. Took me 3 hours from idea to finished product. The gears are from an old CDROM drive that I disassembled for the brushless motor last year. It's the bit that controls the tray. The rest are just scraps of building materials I had lying around. Liberally spray the whole thing with silicone oil and presto! Works perfectly!

The gear ratio is a bit odd though. It's 9.25:1. So every 10 turns I get 92.5 winds. I guess I'll simply count to 11 for every 100 and live with the extra 1 3/4 turns. It's good enough for now.

This is a rubber powered version of my Planktastic.
