Some of you know about my exploits preparing for trying out for the US F5D team. F5D is electric-powered pylon racing on the international circuit. Top three from the team trials of participating countries compete in the world championships in Turnau, Austria August 23rd to August 29th, 2014. The US team trials are in San Diego, CA September 28 & 29. Unfortunately (or fortunately for me), though pylon racing is somewhat popular in the US, F5D (electric pylon racing) is not so popular. Perhaps the models are too fast or too exotic. And/or there are plenty of options on the US AMA circuit. The traditional glow-powered (model airplane glow fuel) classes seem to be pretty popular in the US and have a grass roots following maybe a little the same as NASCAR. Anyway, sounds like we'll have only two or three competitors in San Diego and if that holds true, looks like I better book my tickets to Austria. I'd guess there are probably a good 25 competitors at the WC.

Anyway, the amount of time, effort, and anxiety not-to-mention expense I've devoted (not to mention encouragement, understanding and support from my wife!) makes me feel as though I'll be earning a spot on the team should I make it. Unlike many in pylon racing, though I've been flying model airplanes for years I have little pylon racing experience - I've only started pylon racing this year (state-side in AMA EF1). So I've had to work hard to "catch up" in this new venue by logging laps every morning before...Continue Reading

I guess a blog isn't just for build logs, but can also be your R/C resume. So if I was writing my R/C resume I'd have to include my StratAir Viper F5D racer from Soaing USA. From the maiden flight on April 1 2012 to September 30 I have 114 flights entered in my log book for my Viper. I've already documented the build over in the Viper thread. If you're interested, here's a link to my first post in the thread. You can follow the build with many images and my building and flying comments from there:


Other than that, here's a cheapie "hat cam" video that pretty much explains everything else:

Great Planes Siren (2 min 4 sec)

Been flying small, fast, electric planes the last few years classified as “pylon” racers (though there isn’t an actual racing class for my Great Planes Rifle and my Sunracer). I’m also flying a StratAir Viper which is configured for racing in the F5D class (though there isn’t any F5D racing in the States other than the team trials for the World Championships every two years).

Anyway, for whatever reason I became interested in the Great Planes Siren. The Siren is similar to the pylon racers mentioned above in that it’s intended for speed (sort of), only speed of a different kind--the Siren is rather a beginner “hotliner” where you fly full throttle only for short bursts climbing vertically to rapidly gain altitude, then turn the motor off and glide around. You can search for lifting air (as you would a glider), or put the Siren into a power-off speed dive silently speeding by listening to it “whoosh” past, then power up and do it again!

I guess it was the carbon fiber fuselage and the mechanical aspects such as the gear box and folding propeller that intrigued me—besides, I always like to make things a little better than they come out of the box to suit my tastes! Although the Siren was first introduced in 2005, amazingly, the Siren thread is still quite active over in the Electric Sailplanes forum here on RC Groups. The thread starts out with a well-written and informative review followed by seven years of follow-up posts:

I used to think FPV airplanes were rediculous - until a friend at the flying field let me look through his FPV goggles. Then I thought it was amazing and now I want to get an FPV setup (sometime in the future when I'm not spending all my time on my pylon stuff).

I also used to think night flying was rediculous - until I went to SEFF last year and saw all the amzing night flying stuff. So this year I'm prepping my own night flyer. I'm using an earlier prototype of the FlyZone Calypso EP glider.

I don't know if I'm doing it correctly or the way everybody else does it, but looks good so far. Right now I just have the wings done. Hope to finish the fuse and tail next few days.

I'm using the HobbyPartz LEDs. First I powered them off the battery lead from the ESC, but when I powered up the motor the lights dimmed some, so instead I'll be going with a separate 3S LiPo......Continue Reading

Here's a pic of my B-25 I re covered and re painted last year. Got a few flights on it before I put it away for flying my Rifle.

My name is Tim and I work in the R&D shop at Hobbico. The Rifle project was assigned to me in 2008 (back then I called it "the widowmaker"!). I did the in-house development including flying and modifying the design from the first hand-made prototype on. I also wrote the instruction manual. Since then I've really fallen in "love" with the Rifle and currently have six different Rifles flying with various motors from around 250 Watts up to 600+ Watts! The Rifle is pretty much all I fly right now and by now have logged hundreds of flights between the six (and previous, "deceased" Rifles).

Regarding any modifications I’ve posted and about flying the Rifle over the recommended Watts limit; you have to think of me as just another modeler. These modifications may not be endorsed by the company and could void your warranty—especially when using setups over 350 Watts. Here, I’m the same as any guy who can post on the internet, so rely on your own experience.

My aim is to encourage you to grow into your Rifle as you learn how to fly it faster and faster as your timing, reactions, skill, intuition, decision making and confidence grow.

If there are any of you out there who are interested in the Rifle, but may be intimidated by its small size and speed, I highly recommend a 2S setup using a higher kV (4800 - 5,000) motor. As documented in posts over in the Rifle thread, 2S is still plenty speedy, but lighter so it can be flown more slowly--much...Continue Reading
