These are great light motors for 5" ultralight FPV drones. 4s is a bit of overkill on 3150KV, I prefer to fly on 3s.

Hi fellow rc pilots & rc enthusiasts

SJRC F11 4K Pro - IOS vs Android 5G Wifi FPV Range Test. In this, I use an iphone 8 plus for IOS and a Samsung Galaxy A71 for Android. I was quite surprised with the difference in FPV range, so the app and/or a phones specification can make a big difference to 5G WiFi reception & reliability.

The last tires got very high efficiency but couldn't handle bumps. They also got noisier & noisier at slow speeds because the interior structure was perpendicular to the motion. Eventually it was almost as bad as a gearbox, so the next step was a helical tire. They also got slightly thicker to try to handle bumps better. The material is still under $2 per tire.

The trick with Freecad is lofting a perpendicular tire 1st, then rotating the 2nd outline. It also requires lofting in the part designer. Lions have no idea how the part designer tools became the standard in Freecad when every other CAD program is happy to rely on the simple part tools.

There was a new castillated mechanism for attaching the retaining rings. It made most aspects much easier but gluing was more tedious. The castillations made the hub look cracked ahead of its time.

The old wheels were truly bashed. The 1mm tread & .5mm TPU honeycomb cracked in many places....Continue Reading

I had a crash on the Geotech runway right after hand launch . The fuse broke at the leading and trailing edge of the wing saddle. There was no damage to the prop spinner or motor and radio system. It’s been 6 weeks waiting for a Replacement fuse so I decided to repair. I used Locktite Pro ca to glue the pieces back in place. After lightly sanding with 100 grit paper I used an Olfa wheel cutter to cut out 6 oz glass cloth. After placing the patch on the fuselage I squeezed ca on to the cloth and then pressed down with clear Monocote backing until the reaction cooled down. The tail seam is a known weak area so I reinforced that area as well. Compression wrinkles on the left nose area indicated left side thrust when I put a 20 inch brass tube on to the 4 mm motor shaft. I used the same tube on a new fuselage and no side thrust was indicated. Some down thrust is stock but was not measured. I used washers on the left side of the motor mount to restore the thrustline to neutral. A Canada Dry green soda bottle was used to make a canopy and cowling. Gorilla glue was used to secure the cowl to a 1/8 inch ply firewall....Continue Reading

Lego 42092 Rescue Helicopter with upgraded Blade 130s mechanism.

Upgrades include Rakon Heli Carbon Fibre frame, 180 Trio Three-Blade Head, alloy tail boom, alloy tail motor mount and alloy tail blade fittings.

A breezy day so altitude holding was a little problematic at times hence the bumpy landing.

Lego 42092 Rescue Helicopter (0 min 55 sec)


Not much in the way of modifications need to fit the 130s inside. I cut a carbon fibre plate and after drilling holes to bolt the plate to the Lego kit I then found I could attach the 130s Rakon frame to it! Doh!

So in the end I went with hot glue. It holds well so far and if needed I can free it up with a little isopropyl.

🧐Yep Les Amis,
Vidéo improvisée, sitôt arrivé, sitôt déballé ! Vous trouverez cette vidéo peut être un peu moins riche en images que d'habitude mais comme je vous l'explique, j'avais prévu autre chose (le Veyron30 CR) mais la météo a changé mes plans ! Nous allons donc découvrir ensemble le monstrueux DOUBLE E E101. Au déballage, on découvre une superbe carrosserie et une taille impressionnante pour ce "Scale Crawler" au 1/8, et c'est selon moi, une de ses principale qualité. Pour ce qui est du pilotage, tout fonctionne parfaitement mais il aura besoin d'une petite préparation pour être au top. Les amortisseurs à régler (niveau d'huile et tension), ainsi que l'alignement des roues avant sera un minimum pour de bonnes sensations sur le terrain. Je vous donne donc RDV dans la partie 2 pour lui faire subir les tests qu'il mérite, mais pour l'instant, j'adore ce bestiau ! ... Prenez soin de vous et merci à tous pour votre soutien .

CAN PDB is a new integrated flight controller board, which combines the function of the flight controller board with the power module. When combined
with CORE, it can provide autopilot function for multiple types of equipment such as Copter/Plane/Helicopter/VTOL/unmanned vehicle/Rover, and provide 10 channels redundant main power supply and 88 W 5/12V power output at the same time.Both circuit design and hardware workmanship materials, CAN PDB are outstanding. Up to 952CM dissipating copper sheet and self-developed TTI algorithm. which can provide up to 180 A of continuous operating current for any device, and at the same time provide 0.1 A current ,0.05 V voltage precision measurement comparable to precision instruments.

Core support: V5+ / X7 / X7 pro core .

There are times I'm so excited about RC I end up failing to use knowledge I've gained while flying a small plane. Years ago, when people asked me about my “RC hobby”, I would end up saying RC planes fly for the same reasons real airplanes do. But if an issue occurred with my RC model, I would fail to make this connection myself.

For example, I've been recently entertaining the idea of my servo stalling on takeoff resulting in pitch problems due to the weight of my glider. While it is beyond its optimum weight, the tail does not ever carry the weight of the airplane. How do I know this? Because of all the hours spent behind the controls of a C152 which weighs about 1,000 pounds + 2 passengers, I've been able to initiate climbs, slow flight with my left hand pulling back on the yoke and my right hand on the throttle. There is no way to “lift“ anywhere near 1,000 lbs with my left hand alone! The weight of the airplane is being borne by the main wing being sucked into the air by differential air pressure. The small elevator surface is rotating the airplane about CG to climb or descend, but does not experience any weight. As long as the main wing is in a non-stalled condition, the elevator is able to move about freely to provide pitch “guidance”. I've only had to apply a tiny force using only 2 fingers and thumb for pitch corrections. This is why its sometimes called a “tail feather”. Another topic, your elevator does experience pressure from airflow which is a function of your airspeed. But its not the weight of your airplane that factors in.

Think of your elevator as Counselor Troi, she is there to provide valuable pitch information and never gets in the way of the main mission (main wing)...... come up with your own if you don't like.

One thing is for sure, you do not have to be a real world pilot to know this, study the basics of flight on your own time, do flight simulators. The information is free and available to everyone.

I got some new lipos for the ribs, the difference is noticeable, even faster , they are exactly the same size, different make though and because they are new better balanced.
The boat to boat filming went well, will be added to my collection on you tube, under "colin charles" if that search won't work try Gala Atlantis A500L, you will get the full size as well as my models.

INTRODUCTION

In December 2019, I started a journey (LINK) with my first Scale model build which, although ultimately successful (38 flights and counting), I dont feel was really completed as I intended.

On my maiden flight, the model was in pristine condition, and for all intents and purposes was a high C Grade or Low B grade presentation. It didnt stay that way for long, due to a number of experience factors that I lacked when building it the first time.

1. Model was too tail heavy in the build (needed 400g of nose ballast)
2. Engine Exhausted over the wing (Nitro ate the paintwork)
3. Decals painted with Aerosol cans (smudged off)
4. Internal Tailwheel (not effective)
5. Gear troubles (forward rake, poorly notched oleo fixings (would rotate))
6. Small wheels (contribute to nose overs on damp fields)
7. Poorly tuned engine (transition not tuned while hot, Prop too large 14x6)
8. Tip stall tendency (no washout on wing)
9. Reliance on prop to drop speed for landing (no flaps)
10. Elevator Link was external
11. Overly strong build (can drop some weight)

I managed to remedy all the above to get a fun flyer, but at the expense of appearance and somewhat perforamance.

So, I am going back to do it "better" from all I learnt, to build both a good flyer but also a better built and looking model than the first.

GOALS:
- Better Scale appearance (add all blisters)
- Go for an Eastern European Colour Scheme
- Lighter build (target 3.8kg AUW) by
  • dropping Fuse balsa from 3mm to 2mm
  • dropping wing balsa from 2.5mm to 1.5mm

OTHER CHANGES FROM FIRST BUILD:
- Change to Electric Gear (Pneumatics are good but more fiddly)
- Addition of Split Flaps

Well, here we go!
