My P-51B plans called for a tray between the wings. The tray fits into the fuselage. And when attaching the wing, there was a 3/8” gap. Lotsa balsa and plenty of basswood in that little tray. Not finished, but past this hurdle.

This portion had to be scratch-built because the plans didn’t come close to the reality of the wings and fuse. I was given good advice to complete the fuse and wings first and then custom-build the center tray.

Update: finished the tray and love the way it links the wings. The scoop is like a cool doodad hood ornament.

Okay good people,

First off, this has ZERO to do with the Re-Release of this same model by Horrizon / E-Flite a few weeks ago!


Besides Rocketsled666 who I know is going to say NOT to install any more additional items to make the Retracts work better because one is adding more stuff to fail (failure points), I am wondering what the REST of you OUT there have experienced with these Electric Retracts by E-Flite?

WHY?

Because at the start of initial activation of my Model the Main Retracts will NOT come DOWN so, I can taxi this large & heavy model. Yes, I store this model with GEAR-UP. I would have to disconnect the NOSE Wheel Retract in order to get the MAINS DOWN and then, Disconnect the MAINS and reconnect the NOSE retract so, ALL gears would be in the GEAR-DOWN position.

Not only is this a Hassle but, unnerving from a stand point of flying this model and placing the Retracts in GEAR-UP position as I am NOT certain if they will come back down????

I have the NOSE Retract and the Mains in a Y-Connector and the Output plug towards the Receiver so, NO separate Battery configuration as of yet.

My QUESTION "IS" does anyone have experienced this issue and if so, how did you solve it?

A Video that I recorded today but, as you can see ALL Operated like it should!

TIA!

My current project is refurbishing this Sig LT40 my father built in the early 2000’s. He gave it to me about a year ago and I put a few flights on it but the GMS 47 engine gave me too many dead stick landings so I hung it up. It was also a little tail heavy for my taste. So I pulled it down recently and removed some of the covering at the back, dremeled some holes and recovered it. I also made some adjustments to move the radio forward. Finally, I decided to sand and repaint it. My father had painted it white and used some red pinstripes along the fuselage. I was feeling fancy so used some masking tape and Rustoleum and went to work.

Next I’ll tackle that pesky GMS engine.

I have a mobula7 with new fc cause the stock one burns. I soldered the vtx and the power cable. tested if there will be power in the fc so i plugged 2s battery. And it works. conected to betaflight to set it up (without battery). Then here comes binding it with the tx, plugged the 2s battery but no lights. Tried connecting to usb and lights on. Watched and read some articles about this and said 5v regulator is destroy. So i followed their video in bypassing the 5v regulator and soldered an external stepdown 5v regulator directly from power pads to any 5v pads available (i chose the led pads). After soldering, and plugged the battery, lights on again. So i continue to bind the rx to the tx and it was successful. BUT when i try to arm it. Motors are not spinning. I checked the betaflight, min_check 1000, small_angle 180, modes tab are correctly done. Been to receiver tab and i can see everything is moving or responding to the tx. I tried different motor protocol. And i uncheck the motor stop when armed. Can anyone help me with this?

Held at the end of August, I made the BMFA nationals this year for a couple of days for the first time in a few years.
Lots of fun.
Even in the evening in the beer tent they were making paper planes and seeing whose flew farthest.

I had been at a small rock festival on the friday and saturday, then sunday morning drove up to Barkstone Heath, just in time for the bring and buy.
Some bargains there.

Then it was off to the FPV course, on with the goggles to sit and watch.
After that I wandered over to the stalls, to find a much reduced number from previous years, I suppose that is the way of the world, people buy off the net these days.
Some great models on the flight lines.
And more, just look at the pictures, there are a 160 plus there to look at....Continue Reading

When it comes to the work of the traditional surveying and mapping industry, many people will have a picture of the surveying and mapping staff carrying a variety of instruments over the mountains and mountains.

Nowadays, UAVs are gradually subverting the traditional surveying and mapping operations with its advantages of fast, efficient, flexible and low cost, and become the “new darling” of the surveying and mapping industry.

Compared with traditional terrain mapping methods, UAV mapping can save multiple times and costs. Data collection, which used to take days or weeks, can be completed in a matter of hours through drone operations and quickly complete modeling and data analysis.

UAV operations are usually manually controlled by the operator on-site to complete single or multiple flight survey operations, but the manual operation mode has a large workload during large-scale surveying operations, and the actual operation is more difficult.

Precise control of the flight path is the key to drone operations. Nowadays, the industrial application scenarios of drones are complex, the differentiation is large, and the individualized needs of users are increasing. The demand for flight route settings is also varied.

How does the drone “job” fly?

If you can set the route before take-off, you can lead the drone to the destination like a car navigation, which not only improves the efficiency of the work, but also reduces the loss and risk caused by human error.

mRo Control Zero

The smallest and most powerful autopilot in the world of its kind created for unmanned vehicle builders made in USA!

A high-performance autopilot, specially designed for advanced/professional users who require the best of the best with minimal space.

Built for Builders!

"mRo Control Zero", in its core, is a universal development board and comes fully supported by PX4 and Ardupilot. If you require further customization, the mRo Control Zero will come with all the libraries and examples that will allow you to initialize and access all the board sensors and functions directly via our reference code.

Yes, you will be able to create your custom software for this board in no time, no need to worry about initializing everything (We did it for you). The software is written in C and utilizes a free, easy to install Eclipse-based IDE and supplied by ST. All is included for free with the sole purpose of giving you access to learn, edit, and improve. Be sure to read and understand ST Hardware Abstraction Layer (HAL) license.

But… Be aware of the “limitations” of C, any careless handling of a single byte can potentially provoke a buffer overflow (don’t worry, it won’t damage the board). But hey, This how we all learned at some point, right? The recommended IDE also supports C++ so that you can jump to objects anytime you wish to.

You are Covered!

The mRo Control Zero comes heavily shielded from EMI and highly static hands, so feel free...Continue Reading

I just recently purchased a Balsa USA Der Jager biplane off of Craigslist. I don't usually buy built airplanes because of my love of building myself, but at $300.00, a great build, a plane I always really liked, with a OS Max 300 twin in it.......I had to buy it! It had been sitting in this guy's garage for around 10 years and who knows how long before that (some guy gave it to him before that). I really just bought this for the engine, but the build was so good on it, it needed to hit the skies again! I removed over 2 pounds of baggage: 2 sub C 5 cell receiver packs, 2 separate switches, 1 sub C 4 cell glow driver pack....all 3 @ 2 lbs, some lead wrapped around the motor mount @ 6 ozs. & the 2 Dubro 5" air tires @1 lb! Between the new modern batteries & tires, I put back only 15 ozs. of weight. A savings of around 2 1/2 lbs! Total airframe ready to fly weighs in at only 23 lbs.

Just maidened it this week and what a great flyer. after a slight CG adjustment it flies on rails! That OS 300 twin really halls the mail & the sound is unbeatable in the air & on the ground. No ring ding, weedwacker flying by, sound for me. It's worth every penny I spend on glow fuel for the experience, and wiping it off after each flight........really isn't that hard! Oh yeah..........the nitro smell....................

DustOff #4 - Zeta Z84 FPV Race Wing - Will it handle a much larger LIPO?

#Ground Control RC #Glue & Fly Series #Scratch Build Planes

Here is a link to the Video:
https://www.youtube.com/watch?v=ZzxKwlEpkIA

The Z84 is a pretty nice Wing with a decent power system.
This version is the PNF that has a 2208 2600kv Motor, 30A ESC, and 5050 Prop.
I've found a 6040 Prop works much better than the stock 5050 Prop as it produces more thrust and is more efficient.

In this Flight I'm testing a new Landing Skid System and a much Larger LIPO.
I normally use these 3S 2200mah 25C LIPOs for my larger Planes but I'm using my smaller 3S LIPOs in the "Glue & Fly" Series F-22 Mini V3 today, so I hope this Wing can handle the 60-70 grams of additional weight ;-)

***Note the Setup & Tips Video for this Wing has already been posted.
Here is the link: https://www.youtube.com/watch?v=NQjpcpdKLm0

The KMP 6040 Composite Prop proved to provide a lot of thrust with good efficiency.
When I landed I still had 3.85v per cell ;-)
My new favorite Prop for this Wing.

***Note: I replaced the T-plug on mine with an XT60 Plug on the ESC
