You know you have it bad when you've finished putting together a plane and haven't maidened it yet, but you're already looking at the next plane to build.

Takeoff went fine, needing some rudder input. It was hard to see well against the overcast sky, so I'll fly it later on in the day next time. Noseover on landing, but no damage. I realized later that landing gear can be put on "backwards" with the gear facing backwards instead of forwards. I'll fix the landing gear for the next flight and hopefully there won't be a noseover.

Easy Cub Maiden Flight Day at RSA

My sister-in-law was about to donate my brother's XBox backpack to Goodwill since he never used it, and I told her it looked like the perfect size for my Spektrum receiver. I purchased the Spektrum case foam inserts from amainhobbies.com, and they fit perfectly in the backpack. In addition to the foam, there's also extra padding in the smaller zipper compartment to provide additional protection to the control area of the Spektrum DX7 with its many projections. Since it is a backpack instead of a carrying case, it will also make it easier to ride my bike to a flying field

I purchased a Spektrum DX7 yesterday in order to replace my DX6i. Over the weekend, my Radian went down in the RSA foothills due to loss of signal from the DX6i. Fortunately, I recovered it with no damage since it fell in some deep brush. Too bad I walked through some dried up poison oak to retrieve the Radian. In the future, I need to bring long pants with me to RSA everytime I fly in case I need to do some off trail recovery. I should have done a range check with the DX6i at that point before I flew my Multiplex Gemini, but I didn't, and now my Gemini is toast. After a nice takeoff, it went straight down after it was about 200 feet way. The whole front end is buckled and potentially fixable, but it's probably better for me just to buy a replacement. I performed range checks with the DX6i with its original and a replacement antenna, and I was getting minimum range so I was basically flying without a transmitter antenna. I did some checking over the web, and it appears that people are having less issues with the DX7 than the DX6i, so I'm going to go with the DX7 for a replacement transmitter. I'm getting the Heli model since I recently purchased a used Lighthawk DLG, and the three position flap switch is on the left, which is preferred for a righthand thrower.

Went to fly the Parkzone Radian on a breezy afternoon at Rancho San Antonio with the kids. The wind was high enough to move the Radian around the ground while I turned on the transmitter. Fortunately, I launched the Radian off the drop-off at the edge of the field since it dived down a bit before I increased the throttle and the Radian went up into the air. Iíll have to give the plane more throttle with my next launch. A did a spiral dive with the Radian by pushing the right stick to the lower right corner. I gave E the controls, and told him to only move the right stick and leave the throttle off. I noticed the Radian started to dive at a high rate of speed since he decided to increase throttle and put down elevator on the controls. With the wings flexing up and down, I took the controls from him, cut the throttle, and slowly pulled the Radian up. Another 100 feet and the Radian would have hit the ground and broken up into a lot of pieces. Iím glad I had magnets in the wings so they wouldnít separate under stress. I had a really good landing this time by bringing it down under some power and then cutting throttle with the Radian about 3 feet above the ground. With the headwind, the Radian quietly drifted to the ground.

Cox EP380 with BP 2212-13 motor. I had to add 1.5 oz to the nose to get correct CG. This plane really glides a long way when you deadstick in. I overshot the baseball infield I usually land in during my maiden. I'll have to fly it at RSA next time which has a longer field.

Here are some pics of my Multiplex Gemini on the back of my Kona Ute utility bike. I originally got the bike for trips to the farmer's market, grocery story, and tennis court, but I found that planes the size of the Gemini fit perfectly on the back. With a three-point attachment with velcro, the Gemini is very secure, and I don't have to worry about finding parking at Rancho San Antonio. Radio and batteries fit in the side bag.

Mark Frauenfelder's appearance on Martha Stewart and his vibrobot inspired me to create a vibrobot out of a slowstick:
