I think all is working again now. Please leave a comment on a photo somewhere if something you need is not working still.

Pretty strange but effective motor mount. It achieved the correct right and down thrust. The offset geometry aligned the prop shaft dead center at the cowl (well, soon to be) exit for the spinner. pfinn Pat's Custom Models Brown B2 Miss LA Build 05-Feb-16 00:11 Views : 478 pfinn Pat's Custom Models Brown B2 Miss LA Build 05-Feb-16 00:08 Views : 472 Stringers on top and rear belly. Need to install servos, motor and push rods before closing up the rest of the stringers. pfinn Pat's Custom Models Brown B2 Miss LA Build 03-Feb-16 00:16 Views : 556 pfinn Pat's Custom Models Brown B2 Miss LA Build 03-Feb-16 00:12 Views : 563 Framed up the fuselage.

I've added some radiussed(?) gussets to some joints that looked susceptible to breakage. And a couple just for looks. pfinn Pat's Custom Models Brown B2 Miss LA Reference 17-Jan-16 04:26 Views : 589 The geometry (monkey Motion) was calculated by the Helicopter guys (which I am definitely not!) and I began to CAD up all the parts, then fabricate all the parts (minus the gears and motor), assemble, and test this thing. It fly successfully in the simulated Mars atmosphere in JPL's HUGE vacuum chamber the test all the Earth orbit satellites in. Just nine little "Hops" but it actually did better that the 4 channel vehicle. Here's a JPL video. I made most of the Rail vehicle, and my two channel is at 1:57ish. http://www.jpl.nasa.gov/video/details.php?id=1355e. pfinn Pat's Custom Models Brown B2 Miss LA Reference 17-Jan-16 04:10 Views : 414 This is something I did for work last year. JPL came to Aerovirnment (where I work) to test the feasibility of flying a rotor-craft on Mars. After a successful proof with a Rail-Guided model in a very large vacuum chamber to simulate Mars atmosphere at JPL, we were asked for a Free-Flight model to further prove the concept. We decided that some control would be needed so a 2 channel (throttle and yaw)) would suffice. Atter further consideration a 4 axis craft was decided on though the Boss Man still wanted the 2 channel for backup. Hence I was told I was on my own to develop the 2 channel vehicle. pfinn Pat's Custom Models Brown B2 Miss LA Build 17-Jan-16 03:20 Views : 502 After a couple lunch-time builds and after hours, the tail feathers are done and the wing is almost ready for shaping. Blazing florescent lighting doesn't make for very dramatic lighting. The laser cutting on this model is superb. pfinn Pat's Custom Models Brown B2 Miss LA Build 18-Dec-15 09:39 Views : 606 The New Guy. Rolo (Roland). Nico (the old guy from my Me-109) became dinner for a local Coyote about 2 years ago. Page (3 in total) :  1  [ 2 ]  3  [ < Prev ] [ Next > ]
