    Soma Sandworm fatbike discontinued

    After ordering, and paying, for one (bare frame) on the 21st. of December, in MEDIUM size, I had yet to get a shipping date, so today I made the call. The New Jersey based business (first problem, I'm in Idaho, but their website had the best price and what I wanted in stock, so what the heck)...

    Bigger tire in front?

    I have heard of some using a smaller tire in the rear, to get a better gear ratio, but I am considering going with a 2.5 or 2.75" front tire (26") on my eMontague to make it a better trail bike. Right now I have 2" tires, on a 22 mm rim. I would, I am told anyway, have to get a larger rim to...

    another e plane upstart

    What a great name for a company involved in electric aircraft, "Eviation"! I saw this on one of the flying forums I'm on, and I at first had a hard time finding the means of propulsion as the picture was small. OK, pusher prop in the tail, nothing new there.....but two additional props out at...

    Tesla 3 Perfomance model test drive

    I know a guy who has been a major Tesla geek since the getgo, and I got to drive his earlier (since sold, with 140 K miles on it) first gen Tesla a few years ago. Today, I got to drive his brand new (2,000 miles) model 3, the Performance version, AWD! 150 MPH top speed! 310 miles range! 75...

    Segway Mini PLus

    While on my e Montague today, riding from the airport into town, I saw a guy riding one of them. What impressed me was the way it handled the icy sidewalk on the shady side of the street. Not smooth either, he didn't even slow down, he was obviously an experienced rider. I asked him what it was...

    practical range

    I flew to West Yellowstone MT, via the Grand Tetons, this weekend, in my little homebuilt kitplane. It's nothing high tech, mostly aluminum and fabric construction, with a chrome moly fuselage. Slow too, for an airplane. The E Montague folder came in very handy as usual once on the ground, as...

    Electric hot air balloon, sort of.

    https://www.flydoo.fun/ Wow, this guy has been working overtime on this concept. I bet it's driving him crazy he has not found a practical way to use the in flight propulsion system to also do the initial inflation. I see he still uses a gas powered rig for that. It'd be interesting to see how...

    We don't need no stinking charge controller!

    For some years now, my grid tied, battery based 3500 watt Outback inverter (24 VDC) has sent power into the grid, the main soure of this power is my micro hydro setup, which puts out a high of 34 amps, to mid 20's later in the season as the flow drops. The way it works is once the two 12 volt...

    52 VDC to USB (3 volt?) converter

    I found myself in the ridiculous position this weekend of having 17.5 AH's of fully charged 52 VDC battery, and with a dead cell phone. I had my 12 VDC phone charger, while I realize there are converters for 12 to 52 VDC, but I was wondering if there is a very light and simple way to charge my...

    Trail flat, an unexpected problem.

    Long story short, I was getting some rim strikes on my Montague folder I carry in the airplane, about 3 miles up a remote trail in Montana. So I stopped and added (I thought, based on the amount of strokes I pumped) some air pressure with my trusty manual pump. Got another strike a few minutes...

    Blackfly at Oshkosh

    https://www.avweb.com/eletter/archives/101/4114-full.html?ET=avweb:e4114:527231a:&st=email#231245 Looking good, especially as it is a very tough crowd crowd there, a static display won't cut it. I've flown there several times but have passed in recent years, too damn hot and sticky, and...

    hybrid plane

    Having a PluginPrius as my daily driver, and also flying a Rotax 912S powered LSA, I can see the hybrid concept being workable. Lots of power for takeoff using both, in cruise just one power source would do the job. Complexity and weight (that's all!) are probably a deal killer for...

    One big ass pole mount array

    My own design, for better or for worse, 4 arrays, each with 12 245 watt modules, all on one big ass pole. This is what happens when a crane guy also does solar. The benefit to me and my customer was this was all done in my shop, not on site, so I work cheaper. The big pole was direct embedded...

    I couldn't decide whether to go snowboarding, or ride.

    So I did both. 8.4 miles, round trip,1300' vertical higher then my place, the local kick ass ski area, 45% black and double black diamond. Coming down the 12% grade I realized I had the possibility of hitting the usual 45 mph or so (over 50 if I tucked), and I had never gone near that fast with...

    Big upcoming PV project near a HUGE commercial PV project

    I got a call the other day from a farmer who has leased out some his farmland to a commercial concern for a large PV operation. This facility was installed last year and is currently (ha ha) producing power. I asked him, "does leasing the ground out make you more money then farming it?" He...

    e bike in the ski plane

    The first time I've rode the Montague all winter, what a blast, especially with the BBSHD/Rohloff hub combo. Ski planes are rare enough, ski planes with folding e bikes....I think I'm the only one.

    Getting new registration for the plugin Prius

    Walking up to the counter at my county vehicle registration office, I handed the lady my info from last year. She immediately asked, "is it a plug in?" Yes, I proudly said, "that will be $75.00 extra," she said. Then I asked her what would have happened if I had said no it was a regular Prius...

    first drone caused aircraft accident

    Supposedly anyway. Just saying, losing control of an aircraft and blaming it on a drone could be a future catchall excuse for screwing up. For decades it's been "a gust of wind came up", times change. I'm not saying that's what happened here, but it did occur to me. If there is no concrete...

    e flight in VTOL

    Looks like it's happening with this crew, moving beyond artist's renditions into the real world, taking real live people actually up in the air, cool. The Ehang VTOL https://www.avweb.com/eletter/archives/101/3914-full.html?ET=avweb:e3914:527231a:&st=email#230287
