I purchased this plane to long ago and have allowed it to sit unused .
Well I have been stuck at the house for the past couple weeks due to a bad Poison Oak encounter
So I have been working on getting caught up on my aircraft projects
Today I finished up my 2nd 48" Extreme flight Edge 540 it is all setup and prepped for a maiden less setting GC .

This afternoon I brought the Seagull Yak 54 in the house Got it bound and setup on the radio installed an OptiKill .... may not ever be allowed inside the house again after it gets fueled and flown so I got a few quick pictures of the two planes while I had them in on the dining room table where I do most of my maintenance .

Review (ip) of Robotdog RD2205 Racing Motor 2300KV/2500KV from FPVmodel




My Robotdog RD2205 Racing Motors just came.

Motors come in plastic bag and inside is just motor and lock nut, no bolts, so you will have to order some M3 screws separate if you already don't have some at home, or this are motors for you first build.





Mine are 2300KV version.

I had been reading about building RC electronics like ESCs and receivers. While beyond my ability, I think it is interesting to read about what makes these things work. The fishpepper uSKY receiver was of particular interest to me because of the 10mm by 12mm size. While the tiny SBUS receiver started as a hack/project, assembled versions had become available here and there. I had come across a professionally assembled version from a factory in China. It looks identical to one now sold on Banggood. Anyway, the receiver operates at 5V. Compatible with the FrSky D8 SBUS protocol, binding to the Q X7 transmitter was simple. The assembly is neat, clean and a bind button has been added. The antenna wire is a generous 144mm long. So it was trimmed to an appropriate size for my quad. After insulating with heat shrink, the tiny receiver was tucked in between the standoffs of a 16mm stack. First tested inside, the uSKY worked reliably. Outside, the control distance is said to reach 200m. The 25 mW FPV signal only carries about 100m+ but the RSSI was still strong at that point.
Note: Betaflight 3.3.1 CLI syntax "set serialrx_inverted = ON now replaces the old "set sbus_inversion = OFF
To purchase a fully assembled receiver go to Banggood.com and search for 8CH-SUBS. Yes, they misspelled SBUS in the URL/description. Or, for more information about the open source check out https://fishpepper.de/projects/usky/

RCG'S SUBJECT THREAD: https://www.rcgroups.com/forums/show...-Build/page177

Many mods added and kit bashed including scale instrument panel and cockpit interiors; machine guns and dice flaps. May add option for bomb drop also - dependent on weight considerations.

Wet news print worked very well as masking but did leave ghost-print image on surface in some cases. Un-printed news print paper would be perfect masking.... light adhesive tape, sticky notes, etc all lifted paint.

Most of the build all is complete at this point - however dive brakes currently remain undecided due to added weight but are temporarily being installed anyway....Continue Reading

This is the upgraded Realacc Lipo Battery Safety Bag (155x115x90mm) with luminous handle.It stores all my FPV racing batteries safely. I like its flexibility due to the use of velcro fasteners.

Xiaomi MITU Drone Review | Unboxing Setup Flight Test and Camera Footage (27 min 34 sec)

The Xiaomi MITU is pretty good competitor to the Ryze DJI Tello and priced at $20 less.

PROS:
-Ultrasonic stabilization works great. The quad maintains its position when hovering without minimal to no movement
-Solid altitude hold
-Smooth video output despite not having a micro SD card slot
-$20 less than the Ryze DJI Tello
-Flies surprisingly well and easily via the virtual sticks; sticks appear wherever you place your thumbs on the screen.
-4GB of internal storage for photos and video

CONS:
-Camera quality is not terrible, but just meh
-No image stabilization
-Flight time is more like 8-minutes vs. the advertised 10-minutes

👀Please note that the MITU uses a 5.8ghz WiFi signal, so you must have a smartphone that accommodates 5.8ghz in order to fly this drone....Continue Reading

Halloa guys

Soooo.. I just ordered me 2 identical quads, and I'm posting this cause maybe you can save a few $$ on this as well
apart from the price I was interested to test this setup as well though..

Link to the quad: KingKong / LDARC 200GT Lightweight 5-incher

Sooo.. apart from the price.. What is different here is the weight of the quad.. They didn't go for a monster-power quad, but for a lightweight one instead.. I like that idea! In my mind this does Not make it a racer though.. I'd say it could be a fun freestyle basher..

Allso: I ordered 2 of them myself to be able to do blind-tests between firmwares with..

DutchRC - A 5-inch FPV Quad for crazy money?? :) I'll take 2! (or shouldn't I?) (5 min 55 sec)


Specifications:
wheelbase: 200mm (true X)
frame: 4mm CF with allu cage
motors: 1806 2500 kv
ESC's: 20A 4-in-1 DShot600
props: 5043 x 3
FPV cam: Runcam micro Swift

Greeting my friends! I took some time and removed all of the support material from the aft turret. I also used my Dremel tool with a fine sanding drum to clean off any remaining support material. Looks pretty good. I'm pleased with the results and the depression rails.

I've started the forward turret print this morning. Initially Octoprint says 2.5 days. The forward turret also has some of the cockpit and chartroom walls attached. That's why I think it will take about 3.5 days, Monday morning around 7:00am.

Photos are on my iPhone, so will take a few minutes to get them added.

History

The P.215 was an advanced jet night fighter project by Blohm & Voss during WWII. With a crew of three including the pilot, a navigator and radar/radio operator/rear gunner, it would have been powered by twin Heinkel HeS 011 jet engines set low to the rear, had a tailless swept-wing layout and heavy armament. An order for three prototypes was received in 1945 just weeks before the war ended before any significant detail design work could be begun.

Highly advanced, it would have featured a comprehensive all-weather radio navigation suite and the advanced FuG 244 target acquisition and gun-laying radar.

The P.215 featured a main wing of constant chord and moderate sweep, with small landing flaps forming rear root fillets. Stub tailbooms at the wing tips supported tapered outboard tail surfaces. The horizontal stabilisers and attached elevators were angled downwards both in incidence and, more sharply, in anhedral. The neutral or negative angle of incidence provided longitudinal stability and, in conjunction with the anhedral, contributed to directional stability. Small vertical fins added to the directional stability and supported rudders.

Several armament options were proposed, with the main armament clustered around the nose intake and comprising a mix of heavy 30 mm or cannon with or without rockets. An unusual feature was a further pair of 30 mm cannon set either side of the rear fuselage and pivoting more than 90 to fire either rearwards or upwards. Provision was also made behind the cockpit for a single rearward-facing 20 mm gun with up to 50 elevation, and for two 500 kg bombs beneath the fuselage.

This aircraft would have been formidable with a prospective speed of 860 km/h (534 mph) at 6,000m, a range of 2,200 km (1,367 miles) and a service ceiling of 11,000 m (36,000 ft)!

Here are some pictures of my Tonka Summit and the slow build of it .

< PLEASE FEEL FREE TO COMMENT AND OR MAKE SUGGESTIONS>

Using a Dragon link(433mhz) RX and TX on a Spektum Dx8
channel 1 is throttle
channel 3 is steering
channel 2/4 is pan/tilt for head movement
channel 5 is hi/low gear
channel 6/7 is for front and rear diff lock... however i am going to put them both on one channel as i see no reason to have seperate locking front or rear diffs. and will free up a channel.
channel 8 is for the arm raise.
channel 9 will be for lights and or horn( yet to come)

for video i have head tracking as well as manual on the TX...
using 1.5W 1.3 TX with a TrueRC puck antenna .
ground station is a relay of 1.3 to 5.8 set up.. but can plug straight in to the 1.3 if need be to free up 5.8 for other drivers/flyers.
