The last few steps are to get the front of the plane ready to go. Let's mount the exhaust stacks and cowling.

Install the Cowling & Exhaust - Phoenix Model 20cc 68" Mitsubishi Zero ARF (9 min 25 sec)


"The first engine upgrade came with the introduction of the A6M3 (Model 32). The new model utilized a Nakajima Sakae-21 engine. The Sakae-21 was also an air-cooled radial with 14 cylinders in a double row producing 1130hp at 2750rpm. The new engine also incorporated a two-speed supercharger for better high-altitude performance. The powerplant had a down-flow carburetor and a redesigned cowling to incorporate the air intake at the top/center of the engine cowling."
"The new engine was used on the Model 32, Model 22, and Model 52."
"Some slight changes were made to the engine after the A6M5 (Model 52) was introduced. The most noticeable visual difference was that individual exhaust pipes replaced the older grouped exhaust pipes on each side. This allowed additional thrust to be generated by the engine exhaust, but required a redesign of the cowl flaps and additional heat shielding for the fuselage."

This is a follow on from my previous blog entries regarding ground FPV using a 3 axis gimbal to stabilize the camera. The below pointers assume that the FPV gear is mounted to the chassis under the body shell, also consider that my vehicle is primarily for offroad use.

Body style impacts FPV view, shape of the hood, cab height, and where the windshield is positioned and angle all play a really big part of the view available.
Clear side windows, cutout windscreen
Body reinforcement around the windshield area (Shoegoo and drywall tape)
Velcro sides of body to chassis
Clearance one or two cm between the roof and the tallest parts of the gimbal and camera
Bonus points for a rounded roof line as this might give a litte help rolling back onto the wheels!

One more thing worth mentioning, the cage style bodies will likely provide better view all around as they have so much more open space to look through (ie the side windows). Those are the essentialls, a bit of discussion to follow...

The WL Toys 104009 is recently released a 4WD RC monster truck. It is made by WL Toys, one of the lower cost RC Car manufacturers that tend to strike a good balance between performance and affordability. This particular car is stated as 1/10 scale but is about the size of a typical 1/12 scale, still big enough to perform off-road. In this review I'll cover what I like about this car and what I don't like so you can make a decision to see if it will suit you or not.

My full review is here: WL TOYS 104009 MONSTER TRUCK REVIEW: DRIVES GREAT WITH 1 KEY ISSUE

🧐Yep Les Amis,
Améliorations notables et performances au RDV ! J'avais hâte de tester cette nouvelle version du RACEWHOOP 30 de chez HGLRC et je ne suis pas déçu. Le nouveau matériau utilisé pour les Ducts (protection d'hélice), en plus d'alléger un peu l'engin, protège réellement les hélices cette fois ! Même si ce matériau sera plus cassant que celui utilisé sur l'ancien, il est très résistant au chocs et ne vous obligera pas à changer une hélice sur chaque crash moyen, GROS PLUS ! A cela le fabricant ajoute un support caméra en carbone qui permet de modifier le tilt, une protection de l'antenne FPV, un buzzer, des leds et un aileron qui protègera la lipo sur des chocs de face. En bref, DU BON BOULOT selon moi. Efficace pour les cinématique, la proximité et du freestyle, ce nouveau RACEWHOOP reste un appareil très polyvalent et durable ! ... Prenez soin de vous (et des autres) et merci à tous pour votre soutien .

HGLRC RACEWHOOP 30 Upgrade - Review Test Démo - GOOD JOB ! (37 min 7 sec)


🧐NOTATAZ : 18/20 Bel Upgrade !!!
Les + : Autonomie Correcte, Réglages ok sorti de boite, Très polyvalent, Précis, Caméra réglable, Puissant et Très résistant !

The wing is nearly finished and I must say that ball links do not garner the love they deserve. Because the Virage has limited up aileron and flap movement, ball links provide enough clearance and travel. One can easily achieve 45 degrees of flaps, which is like opening the barn doors.

Flywoo Cinerace20 HD

Description:

I ordered this with the XM+ (from Makerfire because they were quite a bit cheaper than Flywoo?!?) on the 15th, Paid the extra 27 bucks, and got it today (the 22nd). The difference in price for the quad between the two sites basically made the DHL shipping free...

At this point, I only have 4 batteries through it (450mAh and 650mAh), so here are my very initial thoughts:

-It set up pretty quickly. I spent about as much time changing the switches in Betaflight to what I use as I did on anything else.
-Binding was simple (ACCST firmware).
-Having a Mobula6 and a Mobula7, I was very pleasantly surprised that it had the full range of any of my larger quads.
-Cruising around flight time was 6+ min with the 450 and 7-1/2+ min with the 650. Brand new batts, so not broken in and MAY or MAY NOT get better.
-Stock PIDS worked well for me.
-No beeper, so only motor beeps for lost signal and Aux beep.
-I watched reviews that said that the USB port for the FCB stuck out too far and so was something to look out for if you crash. I don't see it as a problem. I'm wondering if they've made the bottom pad a little thicker, or maybe I'm just not as concerned?
-They call it a 2 inch quad (that's props), but that may be misleading to some, it's a 90mm quad.
-DJI HD! That about finishes off the Mobulas for me. Someone downstream for me in the family is going to be happy to get them.

I am very happy with this quad (my Christmas present, so I only get a few more flights on it before I lose it for a couple of months). That's about it for now.

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

Made another attempt at this and I cannot even calibrate the receiver. It immediately goes from green to yellow and freezes. No support from Frsky.
I’m finally done messing with this POS. Going to buy a Hobby Eagle and see if that works. I was finally able to calibrate the receiver it flashed yellow and then green. According to the instructions it completed its process. Put the receiver back in the plane and the three prong switch fails. I have stabilization at all levels. There is no off mode. Once you go through this process who knows what else upgrading may fail. I will have to check all of my planes before flying not taking any chances.
STAY THE HECK AWAY FROM THIS RECEIVER
I am persistent but it still failed to calibrate when using the LUA script. Time to move on

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?
