Cut up a perfect new Lighting EPP wing kit into 3 pieces for portability and to carry on my ebike. Was an experiment that worked out pretty well. Kit cost me about $20 so no loss if I failed. The wings are now very stiff, the new wing is lighter than my old one which I had embedded LEDs. I hold the wings together with a couple zip ties. Takes about 5 minutes to assemble it at the field.
All up weight with 64gram 800mah lipo is about 330grams. That includes metal spinner on folding props and a bigger 15amp ESC. The old wing really flaps its wings on a windy day but this wing is very rigid. CG is at 10cm from leading edge. I don't know how anyone can fly with it at the recommended 50mm. Perhaps it is 3D at that point and I can't fly 3D. It is powerful enough with a 3S lipo to move out pretty quick. I fly around at about 40% throttle.

My maiden went ok but on the third flight the battery dropped out the bottom and I flew it down to a landing without any harm. Looked pretty funny flying with the battery hanging below by the wires. Guess that is the inevitable hazard with the battery hatch being on the bottom of the fuselage.
The video is kind of long and drawn out and out of frame sometimes. Maiden plus one flight is at the end. My wife kindly videoed but in portrait mode. I was training her to video my flights but she has already lost interest so will have to self video in future flights.

Very happy with how this wing turned out. I fly at a large university football field and it is perfect for that size field.

At 9:15 on October 15th, in the Haicheng Park of Hangzhou Future Science and Technology City, a drone quickly took off and then flew away. It has 4 cups of freshly brewed coffee in the "belly" and flies to the future research and development park 3 kilometers away to send "Express". Next, the drone distribution area will gradually expand from the test scene of Hangzhou Future Science City to the whole city of Hangzhou.
On the same day, the Civil Aviation Administration of China issued the "Special Class of UAV Test Operation Approval Letter" and the "Unmanned Aerial Vehicle Logistics Distribution Operation Permit" to Hangzhou Send Bar Logistics Technology Co., Ltd. This is the first license for the pilot operation of a certain type of urban scene for UAVs issued by the Civil Aviation Administration of China. Yin Shijun, chief engineer of the Civil Aviation Administration of China, said that the issuance of this license is a milestone in the field of unmanned aviation in China.
Send Bar Logistics is a subsidiary of Hangzhou Xun Ant Network Technology Co., Ltd. The ant established in 2015 has grown into a key enterprise in the domestic commercial drone field. Before being granted the operation permit, Xun Ant has completed more than 20,000 logistics operation scenario test flights in the test area of ​​Hangzhou City and Huzhou Anji and other mountainous areas, and passed the specific operational risk assessment...Continue Reading

I was making a "robot car".....
Then saw a tracked "robot car"......
Then fluked a link to a 3D Printed Tiger 1 tank..... which led to another link of a much bigger 3D Printed Tiger 1 tank.....
By then I was thinking a big Tank might be a lot more fun! With more room in it to add anything I want, plus that is was going to be a 'robot' autonomous vehicle - but now it is going to be a mix of RC and Arduino/autonomous.....

I could sort of see it would be a fairly big project, but it is growing bigger and bigger - in work/time/effort, not size.
So this could be a very long project to complete!!

This specific Tiger 1 Tank version is originally made by Adam Owen, who made it as a PC case(!)... a whole high power gaming PC inside the tank!
http://community.coolermaster.com/to...ion-build-log/
A driveable PC Tiger 1 Tank !
https://www.thingiverse.com/thing:507034

But during investigations and testing of some parts of it I found a LOT needs modifying and improving, so whilst it is based off that tank it will actually be quite different - in construction, the stuff inside (no PC etc)......

Mine will also have a major addition of great importance! SUSPENSION ! I am still designing aspects of that, working out whether it will use Springs or Torsion bars.
It will also have Ball Race bearings for all wheels etc.
The motor drive system will likely be Nema17 Stepper motors, not normal motors running through gearboxes. Though they will still have one gearing stage of the motor Pinion to a larger Drive Gear.

Adam's tank is more of a BASE to build upon - so lots of it will be of great use, though more will be changed (improved) than kept as he designed it!
I have begun the project but who knows how long it will take!!

Hi guys after the motor failed and my best mate Steve fixed it for me ,I refitted it in the goblin and did test flight OMG the heli was doing a belly dance the rotor disc was steady but the heli was doing a belly dance under it the ESC is a YGE and for some strange reason the ESC has lost its memory so had to do a reset up , well that fixed it
That was a strange going on

Review Part1 - Mobula 7 Brushless Micro Quad - 1S-2S

#GroundControlRC #GlueAndFly #ScratchBuildPlanes #Mobula7 #PowerWhoop

Here's a link to the Video: https://www.youtube.com/watch?v=wbf_y4WGr9U

Well, I completely wore out my Brushed Tiny Whoop a few Months ago so I decided to get a more powerful Micro Brushless Quad that I could fly indoors as well as outdoors.

The Mobula 7 seemed to fit the requirements and has gotten lots of positive reviews.
I'll list the Specs, things that give me pause, some things that perhaps could have been done better, Tips, Problems & Solutions, as well as some of the Cons I've heard from other reviewers.
I'm way out of practice with Quads so rather than try to impress you with my flying skill I'll show you how easy, or hard, it is to fly this Quad from the perspective of someone that's so out of practice they might as well be a Newbie ;-)

Part 2 will be outdoors on 2S ;-)
Nothing fancy but we'll see how well someone can progress in skill with this Micro Quad.

The stock landing gear is good for rough ground or sand/snow/mud as the large tires provide added floatation and little rolling resistance. Once in the air though the large frontal area provide drag. The wire gear sags and gives negative camber when on the ground. You can bend the axles down for positive camber but now she looks like Cessna Birdog! because the axles are approximately .75 inches aft of the leading edge the tail wheel has less weight compared to axles that are in front of the leading edge. This and rolling resistance can cause nose overs while landing and decelerating on certain surface conditions. Prop strikes and fin damage can result that might end further flying for the day. Here is an alternative landing gear system that reduces the above negative aspects. Like any modification be careful and responsible when operating and proceed at your own risk.

I chose the #132 Robart Scale Diamond Tread 2.75 inch tires because of their low bounce properties and looks. The landing gear is the Dubro Super Strength .35-.61 size. Dubro Axle Shafts 5/32 are bolted to the injected molded gear after drilling out a 5/16 inch hole. There is a pilot dimple on the gear but there is room for a different hole for a slightly lower axle location.

The Maule has sufficient foam in front of the stock plastic landing gear parts. Plywood that is 1/4 inch thick by 3 5/8 wide by 2 inch long is used with 3/32 inch thick plywood longerons to carry the stresses to...Continue Reading

Free Flight SU-27 found on Feebay ..
With discount , cost around $5 USD or less .

Wow ! Came fully bent in the post ( see pictures ) ..

But it was an opportunity to test some ideas I had .
Got out the old clothing iron , bumped the temp to 80deg C and proceeded to iron out the wrinkles .
Nope , not doing a good job !
Bumped the temp to about 120deg C and I was just starting to melt the foam ..
At just over 90deg C the iron was doing a half decent job .
I had 2 layers of house hold paper between the foam and the iron at all times .

But there was a lot of bent to go around .
The motor had got bent as well and would not straighten out .
So I had to cyno it reasonably straight .

Assembling !

So the parts have these little tabs that get pushed thru holes .
The foam is SOFT , I mean soft .
Best to use needle nose pliers , very carefully push the pliers into the hole and just barely thru ..
Grab hold the TAB , and pull it thru ..
Much easier than trying to push the tabs thru the very small tight holes .

Once assembled .. Its not overly bad !
CG looks to be about right , and you just need to tweak the control surfaces for a decent glide .
It's windy outside , so the SU 27 glides like a tissue ..
Really need some UBER low wind ( no wind ) or possibly a decent indoor space .


Free Flight Micro Capacitor Powered SU27 (1 min 3 sec)


Was windy yesterday ..
This morning was calm , but a slight drizzle ..
Oh that weather !
