Spektrum module extracted from an Eflight HP6DSM and mounted in my Turnigy 9x.

Set up the 9x (with er9x firmware r760) to PROTOCOL=>DSM2 and DSM TYPE=>dsm2only. Set receiver to bind mode and power up the TX while holding the trainer switch. Works perfectly.

Range test on the ground was better that 4/10 mile (limit of ground LOS in my hilly area) and range in the air was the visibility limit of a 1.5m glider (for both the Spektrum and Flysky modules).

The now module-less HP6DSM can still be used as a sim controller or buddy box for my DX6i by cutting the power and ground lines to the HP6DSM trainer port....Continue Reading

Here are some photos I took of the Bugatti R-100 at EAA's Museum. The lighting was a challenge. These are unretouched and the files are large but any good photo editing software will allow you to pull details out of the shadows. Enjoy!...Continue Reading

(This build log was for the $50 challenge on Wattflyer.com. I'm reposting here to keep all my builds in one place. Comments and questions are welcome of course,)

My entry will be the F7F Tigercat. I wanted to do one for a long time, ever since I saw one fly at the EAA fly in several years ago. This thread also got me juiced up. Originally designed as a heavy fighter for the US Navy, it failed Navy tests but was adopted by the Marines for a variety of roles.

As a model it has a lot going for it: Nice broad wing, ample stabilizer and an almost comically large rudder. It has huge propellers so no problem powering it with efficient outrunners. I had begun to draw up plans a few years ago but was stymied by the long spindly nose gear and small front wheel. Flying off of grass looked questionable for the size I was contemplating. The narrow fuselage and nose gear that retracted through about 110 degrees only made things more difficult. But after the success of my He-219, I began to reconsider the Tigercat. The He-219 had a similar problem with the nose gear so I left it off and made a belly lander instead. That plane is a blast to fly and so I'll do the same with the 'Cat. I dug out the uncompleted plans and finished them up.

Specs:
1/12 scale
WS 51.5 in.
Length 45 in.
Area 440 sq in.
Target weight 45-48 oz.
