Picture 1 :
Just test running the motor to make sure everything is still ok .

Picture 2 :
ESC ( 6A ) has been mounted with double sided tape and a zip tie , as far forward as I can get it without stressing the motor leads .

Picture 3 :
Motor is screwed into place , hmmm two more screws or not ? ( I will run it some with the prop and see if the screws come lose )
Some super glue on the threads should hold the screws in place .

So I am on my way to trying to build a 100 gram RTF wing .. ( Lighter would be better )

Fixing the camber spread the tire wear over a larger area in the center but introduced bigger problems. It significantly reduced the range because of the higher rolling resistance & made the servo skip cogs because of the increased rolling resistance. Went back to the stock camber which wore down the inner edges & searched for a coating to resist the wear.

The solution was to glue fabric straps to the inner edges with E6000 adhesive. After hundreds of miles, they didn't wear off & the power consumption dropped to 280mAh/mile. Initially, the straps were common shoelaces, but kevlar would be the ultimate strap. The key is getting the strap to cover the entire wear pattern. If wear hits a strap edge, it'll peel off.

Earlier coatings were white electrical tape & CA glue, which instantly wore off. E6000 adhesive without fabric seemed to wear off.

One of the early issues I found with X10S are the switch locations are different. Normally I use the back left momentary switch on my Graupner MZ-24 for telemetry. On the X10S that switch is on the right side. So after deciding what to do I felt it's best to move the switches around so my two main radios have the same switch layout.

A larger issue I noticed was the location of the rear switches. I don't know what Frsky was thinking but the average person cannot reach those switches unless you slide your hand up which is awkward while flying. I decided to drill some new holes and relocate the switches closer the edge of the case.

Here's a quick video:

This is my Unboxing, Maiden Run, and Review for the 26MPH GPToys Flame Peace S916 Off Road RC Truck.

26MPH GPToys Flame Peace S916 Off-Road RC Truck Unboxing, Maiden Run, and Review (13 min 5 sec)

Here are my review notes:

- This version handles way better than my GPToys Fox S911 on all surfaces, especially on pavement.
- The drive time is exceptional! I drove it for well over 15 minutes and it still had plenty of power! I don't recommend doing that though, since it is rated to run under 10 minutes per charge.
- I believe it can go around 26MPH
- It looks great with the color and drivers give it a nice touch.
- There is a nice location to mount a GoPro or a action cam of some sort on it to get fun onboard footage.
- The canopy hinges up for access to the battery bay. It makes it so you can't accidentally step on the canopy and ruin it.
- It is a good size at 1/12 scale.

- The plug change is a definite con for me since I have two other batteries I should have been able to use in it.
- I would like to see this design get upgraded to 4WD on the next release instead of it being 2WD.
- The off on switch is buried deeper than I would prefer.

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.

-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

-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)

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
VTX: 25 / 100mw 16ch 5.8Ghz
