01-25-2007, 06:47 AM
Tower Hobbies is selling a number of light weight good flying , Pat Tritle designed, Dumas electric scale balsa construction you-build model kits, more are on the way. The kits have laser cut parts and decent wood and wire plus, plans and covering material for a reasonable price. These models are somewhat challenging to build but Pat Tritle is always available at his website, Pats Custom Models, or on RC Groups E-Zone to answer questions and give advice. There are build threads with photos and discussion for most of the models on E-Zone. These models are designed to fly scale-like on inexpensive power systems and may will land at near walking speed. I am just an admirer and builder of Pat's models.
Take a look at the current line-up: http://www2.towerhobbies.com/cgi-bin/wti0093p?&C=AAP

I Built The Gee Bee Model From Dumas. It Was A Delight To Build And I Set It Up For A Geared Gws System. Haven't Flown It Yet. Could You Tell Me What You Are Using For Power And The Battery Size? Thanks

You can get detailed info on motors, battery packs etc., used in each of the Pat Tritle models in RC Groups, E-Zone, Scale electric forum "build log" threads. Generally a 50-75 watt outrunner or GWS DXA geardrive with Faigao or Medusa 12mm brushless motor works well in models built light without much beefing up. I am using an Esskay 400XT motor ( $17.90 on sale) from Hobby Lobby in my 19 oz, 48" w/s Pat Tritle #%$^*One-For-Tea ( Cessna 140). Battery pack is a Polyquest 20C 2S 1200 lipo or Polyquest 20 C 2S 800mah lipo, Prop is 9x5 direct drive GWS. My C-140 uses 2 Blue Arrow 4.3 gram servos for ailerons and 2 HS-55's for rudder and elevator. Rudder is pull-pull , elevator is wire pushrod. ESC is CC Phoenix 10 with 3amp BEC. Pat recommends CC Thunderbird 18's in his models.
