Somebody Built My Little Delta Trainer!

This is so cool! Here's the link.

The Super Easy

I spent last weekend with Dad flying some new pilots on a buddy box. We flew them on Dad's .46 Nextstar and on my PFD Delta. It got me thinking about a cheap dollar tree trainer, a concept I experimented with once upon a time.

This guy may have cracked the problem. His Super Easy is a prop and slot delta wing floater. It is super easy to make and it's highly stable. It looks like a paper airplane, which is kind of fun. I especially like how the electronics are protected from a crash.

I'm interested.

SYMA S107G IS NOW 2.4 GHZ!!!!!

The Syma S107G micro helicopter is now being produced in 2.4 ghz. This means that you can fly it past picture windows or under flourescent lights at will, and you can fly more than two at a time. And the price? $23. We live in extraordinary times, folks. This is now officially THE BEST DEAL IN RC. Buy one immediately.

Here is a link if you would like to get yours from Amazon.

1970's Pattern Nationals

With the resurgence in popularity of classic pattern planes like the Kaos or the Dirty Birdy it's interesting to look at archival footage of the real thing. Click here.

KF Airfoil Wind Tunnel Testing

This young man did a wind tunnel test on a flat foam airfoil, a traditional airfoil and a KF step. The flat airfoil performed poorly all around (no surprise), while the KF produced more drag than the standard airfoil, BUT... the KF step also produced more lift.

In a subsequent video he tests a flat airfoil and three KF airfoils on the same plane. The results are fascinating. Powers RC did the same thing with park jets.

Worth a look.
