    S-LSA downsides

    It's a one way street. Just like Exhibition category switches. Sorry.

    S-LSA downsides

    I think you will find that with some of the kit manufacturers as well... Parts are very expensive for what they are (mostly OTS stuff) and there is usually a pretty good wait time. Some companies are better than others, but some really follow the car manufacturers policy of 300% mark up. Good...

    AutoPRSUs engine discussion

    I used a RWS unit on a rotary engine. Wouldn't try it on a 4 stroke... The rotary seemed to be less abusive to it for a couple of reasons. One was the differences in the harmonics. BIG difference. The other was the high gear ratio. More tooth engagement to spread the load. Bearings were the weak...

    Yamaha 701 PWC engines -- why not?

    I never shut it off cause the battery was bad LOL. Had a Johnny Jar and was trained to use it properly :) P3's thank you very much :) ASWO out of Millington.

    Yamaha 701 PWC engines -- why not?

    First thing the manufacturers do to the Police Interceptors is put in a bigger radiator and transmission oil cooler. Old VW's and Fords ran 3500 rpm all the time before an overdrive gear was added to the driveline. A '65 VW did a 36 hour non stop run at 3500 - 4000 rpm from Memphis, TN to Los...

    The devil is not in the gear... It's ALL about harmonics. If you don't harness the power pulses adequately, it doesn't matter if the gears are made out of Vibranium. Yes, the material and hardness matters. Yes, the cut and relief matters. Yes, the ratio matters. However, the power pulses of a...

    Keep up the diligence and hard work and it will be worth it. The time has come for an 150 - 200hp inline 4 and/or V6 success story. Yours is a prime candidate. Don't forget about us 100hp guys :) Fly safe, N

    AutoPRSUs engine discussion

    Having built aircraft with both certified AND experimental propulsion over 40 years, I can offer an observation. Builders that want Certified engines are the "non tinkering" kind. They want plug and play and proven simplicity. They do not care about the maintenance and repair costs involved...

    Ikea style folding CNC table?

    Similar minds, similar circles... So last night while I was trying to sleep I came up with the idea of just changing the X beam on my 32x32 printer. I can use the full 18" of Z travel because the tool head will be stationary in the Z and the table will travel up and down. The gantry will still...

    Ikea style folding CNC table?

    I can use the router on all kinds of things. The hotwire is just for foam :( Saw a 4 bearing water cooled from HY I will look at for about $300. 800w I think. Need something that will hold up to me using it :) Figure this thing can't be as hard as a printer to put together and run, Eh?

    Ikea style folding CNC table?

    I am interested in a CNC router to work in conjunction with my printers. I have an old printer frame that I will use along with some actuators, but need a spindle. I will be cutting XPS foam for my cowl on a 27x27 table. Probably a 8-12" Z. $500 budget. Any sugges How do you like you MPCNC?

    No I hadn't, So sad for their loss. I worked with them awhile ago on the CNC'd parts for their kits. Nice guy.

    Ikea style folding CNC table?

    Sorry, Forgot the picture :) That is PLA material on a cold bed. For Nylon I use a heated bed.

    Ikea style folding CNC table?

    With a heated bed, my nozzle never touches the bed, so the only "torsion" it ever incurs is when it hits the errant bump in the road from the previous layer. With a .4mm tip, I start at a .32 1st layer and stay there. For a COLD bed, I use a build plate of profiled plastic and PUSH the first...

    Surprisingly, Zenair is second in total AC... Dang. I would have bet Sonex or Rans. I bet Jeremy and Randy are miffed. Especially with the issues that were had with the 601. Great recovery and nice planes. Vans needs to come up with a high wing / short field plane. I know it's a BIG departure...

    3D printing in the Homebuilt world.

    Thank you, Russian guy seems to be working on a lot of stuff. I wonder how good support will be. I'll check with Ross and see what he has. Just wanted your opinion :)

    3D printing in the Homebuilt world.

    I can suggest a controller ( I should buy stock :) and that is the Azteeg X3 pro. All you will ever need and USA made. Currently trading at $135 or so. You will make up the cost on other parts saved. My printer uses the board, a power source and a dc/ac relay for the heat plate. Super simple to...

    3D printing in the Homebuilt world.

    Sorry to go off topic here, but a little birdie told me I should ask you about fuel injection for my B&S engine. I am assembling a big block and would like to ditch this baby carb they put on it. Any suggestions?
