NMPRA

So, it’s hard to see in the picture, but I am using peal-ply over the entire laminate and only using breather under the one way valves. Pros: 1. Pulls harder against the surface of the laminate 2. Draws excess epoxy up through the peal ply, and traps on top where it dries and is pealed off when the ...

A few teaser shots, more to come from the DYD shop.....

Come on you guys, this is 2020, the #metoo movement will come after you! Lol :D :D First saw that Kelly in Las Vegas around 93’(?) Cool airplane, Lyle Larson cranked out several Q40 plugs in short order. He was ahead of that curve. The diehard Formula One guys did not like the Q40 formula, but It on...

SO BITCHIN.........Racing now is good and I feel that the NMPRA has done a very good job at making racing more accessible, but the 70's and 80's F1/Q15 scene was some of the best craftsmanship ever! You really had to know how to build and paint.

Cheers, Dave

All the airplanes look good Dan! The Rat has a special place in my memories, Kieth Davidson was a very close friend and did all of the crown molding, wallpaper and plaster work on the first two houses that my wife and I owned in San Diego in the 90's. He was an absolute perfectionist. The owner of t...

Nicely Done Lee......Smart.

Servos typically have three failure modes; hard over (short,wire chafing) last position (signal or power loss) in trail(gear train). Two of those are most likely going to lead to loss of control if it’s on the ailerons or elevator regardless of how many servos are installed. As written, You must hav...

Yep.....I was on a UAS project that relied on a FCU that was shock isolated on a payload tray adjacent to a heavy fuel converted DA50. The vibration and the ignition played havoc with the FCU. They hired an outside consultant and payed big bucks to identify the proper density materials (for the shoc...

From: g. All screws holding the servos to the servo rails or trays and holding any trays to the airframe shall be in place and secure. Rubber grommets shall be used on all servos designed to accept them. If the heads of the servo mounting screws are small enough to pull through the grommets, washers...

So, for those of us up here in the cheap seats, please explain from a form, fit or function stand point, why you would not want to shock mount a servo in a Q40 airframe? I get the two servo redundancy piece, but are you not reducing the redundancy margin by leaving the grommets off? The explanation ...

Thanks. Been a while since I have painted anything. Had to buy some black, the rest I had laying around.

Cheers, Dave

Got some paint on the Ashley.

Hope everyone is having a relaxing Sunday and Mother’s Day.

Cheers, Dave

Yes, I love the classic motorsports tins. Full disclosure, I only take pictures when the shop is clean! I am also working on an electric 3D plane that has been bouncing around in my head for several years. My goal is to have a Q500, Q40, and aerobatic sport plane of my own design. The aerobatic airp...

I have had the Ashley on the wall for two years, finally framed it up. I am looking for change under the couch cushions to put together a modest paint job this week.

One more Ricochet ready to accept the V-Tail assembly.

Working on the Ricochet wing tool as well.
