Convair XC-99: Pretty much the opposite end of the spektrum from the Monsted-Vincent MV-1 Starflight, the XC-99 was an example of adapting bomber designs for cargo use. This time well after the war.

The XC-99 was developed in 1947 using the parts bin of the B-36 Peacemaker. The XC-99 was actually the largest piston landplane ever built. The 230ft long wing and tail feathers were directly borrowed from the B-36 and were bolted to an all new fuselage. It was designed to carry 100,000lbs of cargo or up to 400 troops on it’s two decks.The 135,000lb (empty) airplane was powered by six 3,500hp Pratt & Whitney R-4360s in pusher configuration.

The XC-99 had one of the wildest landing gears of any airplane ever. It’s single main tires were almost 10 feet tall. They proved to be problematic and were eventually replaced with the same truck style system that the later B-36s had.

The one and only XC-99 was actually drawn up long before the B-36 even flew. With delays in the B-36 project the XC-99 got pushed back several years and didn’t fly until the end of 1947. The military decided that they didn’t have any use for such a big airplane but they continued to use the prototype for moving pieces of the B-36. It flew until 1957 mostly inside the US.

Amazingly, the XC-99 actually still exists. It was flown to Kelly AFB in 1957 and parked for display. It stayed there until the base was closed and in 2008 it was moved in pieces to the Air Force museum. Currently it is in...Continue Reading

Once a year the Swiss Air Force opens it Axalp mountain Firing range to the public for a firing display and air show.

It is to my mind a unique event since the F/A-18 Hornets open fire with thier 20mm M61A2 just over the spectators and one of the targets is less than 400m away. The mountain backdrop is also impressive . The valley allows to be highter that the aircraft which is excellent for getting breathtaking pictures.

Getting to the firing range is quite an adventure. It involes a bus, a skilift and hiking for around 2 hours (400m up).

Its an epic and really a unique expirience

I have advice for those looking to purchase this product. DO NOT BUY THIS PRODUCT. Maybe there is someone better then me at getting this to work. The paper instructions, the vendor and FRSKY all say different things about how to install this receiver. Not only did it not work but somehow it caused my S8R to stop working . I updated my transmitter with the current ISRM MODULE UPDATE, flashed the receiver with the current firmware. Calibrated as instructed three different ways, IT FAILED TO WORK. I had to disable the stabilization in the setup just so I can fly my plane. I’m a software engineer 40 years of experience and could not get this to work. If someone else has been able to get this to work please let me know. My advise BUY SOMETHING ELSE

Hey, I am pretty new to making drones, but while soldering the header pins, I accidentally removed the SBUS and PPM resistors. Below is the attached diagram pointing to the resistor. Can anyone point me out any other pin where I can connect my FS-iA6B receiver?

Monsted-Vincent MV-1 Starflight: Speaking of strange looking light transport airplanes, nothing is a lighter transport than the Monsted-Vincent.

In 1948 two WWII Veterans, Robert Monsted and H. Farley Vincent, gave birth to a strange brain child named the Starflight. Built in New Orleans, the Monsted-Vincent was the only four-engined airplane to ever be built in Louisiana. It had four mighty 85hp Continental C-85s in pusher configuration and had seats for six whole people!

The Monsted-Vincent was a very peculiar little airplane. It’s construction could be described as almost barbaric, however it did have some strangely nice features. Firstly, it used 2 position Sensenich “Skyblade” Propellers. It had a retractable gear, although they left gaping holes in the side of the fuselage when they were up. And it had 8 hours of range!!! And I suppose it needed it at 150mph.

The airplane shockingly didn’t seem to attract a swarm of buyers even with the upgrade to Continental O-200s of 100hp. The one and only Monsted-Vincent did seem to fly a lot, but it never amounted to much of anything. The Vincent family owned the aircraft all the way until 1982 when they donated it to the Wedell-Williams museum in Patterson, Louisiana. Sadly, the airplane was badly damaged in two hurricanes in 1992 and 2005 and I don’t know if the remains are still around but I sure hope they are....Continue Reading

Saw this on cnc kitchen and decided to build it. I actually built it last year, but I needed to make some changes so I figured I would document the whole thing in case anyone wanted to build one.

Filament Dry Box || How to properly store and 3D print Nylon, PC, TPU, PVA... (6 min 46 sec)

First I started with a clear box made by a company called Sterilite that I found at Walmart. The boxes dimensions are 16”l 12”w and 11”h. This box came with a (somewhat) gasketed lid and is big enough for 4 rolls of filament.

I found the rod hanger brackets on thingiverse and the spool holders there also.

Zip file for spool holder attached at bottom of page.

Note to self log :

- so far using the Dollar Tree foam board is working great. in the past built with FFF (blue) FanFoldFoam as it is known. used to get it shipped to me in Fort collins, CO from a Lowes in Kansas. The local stores didn't carry it. I've done some online looking and haven't found it available anymore in 2021. The lowes does carry some foam underlayment in 1.5mm, 2mm and 3mm thicknesses. These are floppy (not as rigid as the FFF) and I'm not using that stuff as of yet. Maybe someday...

Using the DT foamboard is still around and still $1 for 20x30 inch piece. The paper peels right off if needed - so easy So i'm enjoying working with it. now that i'm taking care of mom in her declining years I've moved back to Tucson. And it's mid-october so the flying weather is just getting perfect Brought most of my RC stuff from Colorado so i'm ready to build & fly in the wash behind mom's house here. Or the city park across the wash. so handy!

first build back into the hobby is a 120" span scratch build powered glider. Using a wing with 10" chord, easy to build and I'm using carbon arrow shafts for the main spar, again. I've used arrows for building frequently.

i've not built for 10 years now, having taken a break whilst spending my off time at my GF's house in Greeley. Lately, since before Covid, i've spent my pasttime in GTA 5 Online. but that's getting old and i'm up to 110 million dollars in my account so I'll do some R/Cing for a pasttime now. (plus some GTA of course).

This week brought out some excellent slope soaring conditions for us here in S Florida, high pressure a bit up north and to the east brought in much lower dew points ie less humidity and a very steady flow of wind out of the NE/E at 10-20+ mph, perfect slope soaring conditions for our landfill Pompano Hill site. I should note I have nothing hi tech in either my slope or thermal inventory, I don’t compete anymore in TD and I’m not interested in spending $1k plus on any rc glider. Pictured here are some of my retro slopers, one is the Pilot models Divine Wind built from a short kit, the Douglas models Silhouette, new fuselage and tail surfaces reproduced from plans, Scorpio models Falco, canopy area modified due to midair collision, and finally the Pierce Aero Ridge Rat, no mods, repairs or even total re covering, there are patches however since I built her in 1987.

🧐Yep Les Amis,
Toujours pas cassée !!! lol . De retour sur le terrain pour tester la nouvelle EAT14 de Eachine, copie conforme de la WLTOYS 144001, avec l'évolution Brushless ! Réactive et très maniable sur route, ce petit bolide atteint quand même les 60km/h en 2S et 75km/h en 3S, tout en conservant une excellente tenue de route. La possibilité de régler la vitesse en fait une excellente voiture pour l'initiation ou l'adaptation pour les novices. Très résistante et bien conçue, son système de clips sur les parties fragiles vous évitera pas mal de casse et au pire, les pièces détachées sont nombreuses et disponibles puisque compatibles avec la 144001. Malgré mes tentatives de "Fracassage", lol, pas de bobos, le châssis est robuste, l'aileron tient le coup et les pièces en mouvement se dé-clipsent lors de chocs trop violents ! Pour finir, les amortisseurs sont très efficaces et vous autorisent des sauts de "OUF", mais je vous conseille quand même de travailler vos atterrissages !!! mdr... Prenez soin de vous (et des autres) et merci à tous pour votre soutien .

Consolidated Liberator Liner: Lately I’ve been concentrating on airplanes that have a surviving example, but the Liberator Liner is part of a cool genre that doesn’t get much attention these days.

At the beginning of the War, companies were trying to adapt their civilian designs for military use. But near the end of the war, the reverse was happening. Companies knew that when the war ended their military production contracts would be up and they would have to find a civilian market again.

The Liberator Liner was a great example of a company trying to adapt a military design for civilian sales. They took the wings of the B-24 “Liberator” and the tail of the PB4Y and added a rounded fuselage which seated 48 passengers. The first prototype was flown in 1944 before the war was even over and initially they got a contract to build them as a military transport but it was canceled before any production started. A second prototype was built with a different model of Pratt & Whitney 1830s but neither airplane brought any sales in.

One of the airplanes was leased to American Airlines as a freighter and that was the only commercial use the design saw. Unfortunately the concept of using military designs for civilian use was mostly dominated by surplus sales so designs like this didn’t succeed too much. The surplus market sent many of the major aviation names reeling in the post-war era....Continue Reading

When it comes to FPV the better you can see the faster you can go! Which is maybe why we see so many fast street vehicles and crawlers out there. Camera shake tends to limit speed over rough terrain, larger vehicles have less of an issue with this, but will eventually experience it if driven towards the limits of performance. The solution I've found is to use a gimbal to smooth out most of the motion of the vehicle, also this can be configured to accept RC inputs for pan and tilt. The only limitation is that if the car rolls over the gimbal needs to be reset, however this can be done remotely, it’s not so bad. I'd love to write a step by step on how to duplicate my setup but that’s a bit much at the moment. Instead this is here to let you know that IT WORKS. The gimbal essentially mimics what your neck would do if you were sat in the vehicle, stabilize your head and eyes.

End up with something like this:

IT WORKS REALLY WELL! So do it, here are some general working principles to help ensure your success. Maybe I'm missing something but I can't see a better way to drive fast off-road FPV, even slow crawling over rocks is way more enjoyable as the view is not rolling around all over the place.

A search on aliexpress for 'storm32 3 axis gimbal' will pull up multiple sellers letting these units go for under $100CAD. The specific Storm32 board version I have experience with is 1.3x, it works and it’s the only one I've...Continue Reading
