DustOff Flight #2 - More Acrobatic Fun with the Focke Wulf FW 190

DustOff Flight #2 - More Acrobatic Fun with the Focke Wulf FW 190 (3 min 34 sec)


I want to thank my Wife for going out into the Desert with me to film this and other flights.

I just received my Gemfan 8x4 APC Style Props and wanted to test them out on this plane.
They are much stiffer than the standard Gemfan 8x4 ABS Props and they provide more thrust ;-)
Acrobatics are much easier to perform with the additional boost in thrust!

Build, Fly, Crash, Repair, Rinse & Repeat!

Happy Flying!

Review - RacerStar Racing Edition BR1306 4000KV 1-2S Brushless Motor

Review - Racerstar Racing Edition BR1306 4000KV 1-2S Brushless Motor (4 min 46 sec)


How does this motor stack up against the RacerStar BR1306 3100kv Motor?
Well, it is higher KV so it does produce more thrust, however, it also uses more Amps.
The motor is not as efficient as the 3100kv version which is expected since it's higher KV.
If you would like a bit more power and a bit less flight time then this motor will give it to you ;-)
I think I will use this motor for my "Glue & Fly Series" Micro Trainer Plane, TBA.
I think this motor is very well made and the price makes it a great value.
It produces great thrust at low amp usage on a 2S LIPO.
The motor with the prop nut and attached servo connector weighs 12.43 grams.

The thrust test on this motor was performed with various props ranging from a 6" to a 4" prop.
All test were performed using the same 2S 850mah 25C LIPO and the battery was fully charged for each test.

Build, Fly, Crash, Repair, Rinse & Repeat!

Happy Flying!

Tutorial - Adding Struts to your WLToys F949 Cessna 182 (38 min 36 sec)


The Main Wing on this plane has way too much flex and should have had Struts out of the box but didn't.
In this Tutorial we're going to remedy that situation by fabricating our own Struts ;-)

To complete this Tutorial you will need the following Tools & Supplies:

Link to Angle Jig Template: http://www.groundcontrolrc.com/ftp/t...182_struts.pdf

- (1) Barbeque Skewer that is 3mm in diameter and approx. 125mm or 5in. long
- (2) Stir Straws that have a 3mm inside diameter and are approx. 150mm or 6in. in length each.
- (1) Packing Tape or similar Tape
- (1) Pencil or something to outline your Angle Jig Template and mark your Barbeque Skewer lengths
- (1) Material for your Angle Jig; Foam Board, Cardboard, etc.
- (1) Scissors to cutout your Angel Jig Template and a Printer of course
- (1) Utility Scissors, Utility Knife, Exacto Knife or something else to cut your lengths of Barbeque Skewer, Stir Straws, & Angel Jig
- (1) Ruler preferably with a Millimeter Scale so no conversions are needed

Glue & Fly Series - F-22 Mini V2 Acro Practice? Session 22 Flight 6

Glue & Fly Series - F-22 Mini V2 Acro Practice? Session 22 Flight 6 (5 min 38 sec)


Until this year I flew mostly FPV.
I have decided I need to get my LOS (Line-Of-Sight) skills on par with my FPV skills.
I would say that my FPV skills are High-Level Intermediate while my LOS skills are as Beginner as you can get ;-(
I have practiced my LOS flying to this point flying circuit after circuit and figure "8" after figure "8".
I feel like I have become competent at those two maneuvers to become a High-Level Beginner ;-)
Now I feel it is time to start practicing some basic Acrobatic....very basic..Loops & Climbing Rolls.
I think when I can become competent at those maneuvers I will be at a Low-Level Intermediate Class ;-)
After becoming competent at those two maneuvers I will move on to Climbing Split-S maneuvers and Horizontal Axial Rolls.
Once I'm competent at those maneuvers I think I will have entered the Mid-Level Intermediate Class ;-)
Next year I hope to have my LOS skills on par with my FPV skills....only time will tell.
Join me on this journey to become a competent LOS Pilot ;-)
After accomplishing this I will put together a series of videos showing all aspects of my Pilot Training to help those new to the Hobby get their Wings as well.

Build, Fly, Crash, Repair, Rinse & Repeat!

Happy Flying!

Glue & Fly Series - Interceptor Micro V1 Intermediate & Advanced Setup Flight #3

Glue & Fly Series - Interceptor Micro V1 Intermediate & Advanced Setup Flight #3 (5 min 29 sec)


I want to thank my Wife for filming this flight for me.
We made this a Family Affair and had my Grandson with us as well and I had a little 2 Channel Plane for him to fly and get introduced to RC Aircraft.
Hopefully he will become my flying Buddy ;-)

Sorry for the bad FPV footage as this prop had developed a vibration I was not aware of.

Wind is out of the Northwest at 2-5mph.

In this video we have LOS (Line-Of-Sight) and FPV (First-Person-View) Flight #3 of the Ground Control RC "Glue & Fly Series" Interceptor Micro V1 Parkjet.
The Parkjet is configured for Intermediate & Advanced Setup using a 1306 Motor and a 3S LIPO.
The Parkjet in this configuration has a fantastic Thrust to Weight Ratio, is very fast, and an absolute blast to fly.
This is not the suggested power setup for this Micro Parkjet as this is some of the testing we are performing for Version 2 of this Parkjet.
The Version 1 Plans of this Micro Parkjet have already been finalized and are posted on Patreon along with Templates, Decals, and Buid Videos.
Version 2 of this Parkjet is in the testing phase.

Thank you Patrons for your support and Happy Building!

Build, Fly, Crash, Repair, Rinse & Repeat!

Tutorial - Converting an OPTO ESC by adding an SBEC (Switching Voltage Regulator)

Tutorial - Converting an OPTO ESC by adding an SBEC (Switching Voltage Regulator) (17 min 8 sec)

FVT LittleBee 20A ESC BLHeli OPTO 2-4S Supports OneShot125 For RC Drone FPV Racing Multi Rotor
https://www.banggood.com/FVT-LittleB...47791920140372

I like using OPTO ESCs in my Parkjets, however, I like using Switching Voltage Regulators to power my Receiver, Servos, and FPV equipment.
Switching Voltage Regulators are much more efficient than the Linear Voltage Regulators which is what you typically get with ESCs smaller then 40A.
They also produce less heat and use less of your flight battery, a win, win ;-)
So I install these on my OPTO ESCs and have a much more efficient Voltage Regulator that usually ends up being lighter than the same size ESC with a Linear Regulator.
Also a win, win ;-)
In this Tutorial we're going to add an SBEC (Switching Voltage Regulator) to our OPTO ESC.
This will give us a 20 amp ESC with a switching voltage regulator that provides 5 volt at a full 3 amps of power ;-)

Update!!!!

A post by "Per Buch" on this video brought to my attention and corrected my Brain-Cramp in that you do not need two servo connectors on this setup.
You can clip the Ground Wire on the ESC and move the ESC Signal Wire to the Voltage Regulator Power and Ground Servo Connector and it will work fine.
I tested this setup in my Parkjet and it worked great!
Now there is no downside to using this setup as it only requires 1 Receiver Port ;-)
It also decrease the weight to 10.9 grams ;-)
Even better!

I will be performing the Field Test for Part 2 of the Switching Voltage Regulator review.
Stay tuned ;-)

https://www.banggood.com/5Pcs-235-Pi...47791920140372

Another Needful Thing on my list is a set of Spring Terminal Blocks.
I found these in 2, 3, and 5 pin terminal blocks.
I ordered these so I could perform testing of Motors and Speed Controller without the need to solder connectors to them or waste heat shrink.
I've taken time to solder connectors to Motors and Speed Controllers before testing only to find that the Motor or Speed Controller was faulty.
Now what do you do?
Well, if your like me I try not to waste anything as it's too expensive.
So now I have to de-solder all my connectors and I'm still out of the heat shrink I had to use.
Money wasted!
Not anymore ;-)
With these Spring Terminal Blocks I can make all my needed connections without having to solder connectors or waste heat shrink.
Now I can test and make sure my Motors and Speed Controllers work as they should before soldering connectors and applying Heat Shrink! Yeah!
A great addition to your RC Toolbox.

Review - WLToys K969 1/28 Scale Drift Car - Much Fun!

This is an older video but still relevent.

Review - WLToys K969 1/28 Scale Drift Car - Much Fun! ***Update! (9 min 35 sec)


The car is very nice looking indeed. It has 4 wheel independent suspension, 4 wheel drive, and drifts absolutely fantastic!
I had to take it out for a test drive in my media room which has a very low pile indoor/outdoor carpet and it was perfect for this car.
With a little bit of punch on the throttle you can set the car drifting into a turn and reverse steer your way through the turn ;-) Much Fun!
The car seems well built, the transmitter bound to the car receiver without issue. All I had to do was charge the battery and I was off to the races, literally ;-)
The two complaints I have is the motor get pretty hot, will burn your fingers hot, so pick it up by the body not the under carriage as I did the first time, Ouch! Very Hot!
The second complaint, which is the same complaint I have for all the RTR (Ready-To Run) vehicles is not enough throttle granularity. It's a bit hard to do smooth throttle management. Perhaps I can replace the stock receiver with a RadioLink one since I have a much better RadioLink transmitter than the stock one.
The specs say 30 minutes of drive time, however, I would put that closer to 20 minutes especially since your going to be in the throttle a lot to make it drift just the way you want it.
I like the fact that it runs off of a little 2S 400mah LIPO as I have several 300mah 2S LIPOs that will fit perfectly ;-)
You're going to want to buy extra batteries because you're not going to want to stop driving after the first battery.

I give this little drift car a big happy thumbs-up!

Glue & Fly Series - Interceptor Micro V1 Flight #5 - Shooting The Gap!

Glue & Fly Series - Interceptor Micro V1 Flight #5 - Shooting The Gap! (3 min 25 sec)


First, I want to thank my Wife for standing in the cold and wind to video this flight for me.
We left the Desert and headed to the Autumn Forest of the Midwest ;-)
The area I'm flying in is partially wooded and I decided to slow this micro parkjet down and shoot the gaps between some of the trees.
This shows more of the capability of this Tiny Parkjet, the wide flight envelope and the maneuverability it possesses.
This is the most fun I've had yet flying this little plane.
Everything was going fine until I flew behind myself and lost momentary control and landed it in one of the trees.
That's my story and I'm sticking to it ;-)
Needless to say parking your plane in a tree is not the best thing to do ;-)
Wind is out of the Southeast at 5-10mph.
Again the wind was not favorable for this Micro Parkjet that only weighs 107.8g.

Crash Report:
Damaged a bit of foam on the leading edge of the wing near the fuselage.
Ripped off one of the vertical stabilizers.

Repaired with a bit of Foam-Tac and now it's ready to fly again!
Total cost of repair = $0.10 worth of glue

Build, Fly, Crash, Repair, Rinse & Repeat!

I thought I'd take a break from my LOS (Line-Of-Site) Training and get in some FPV Fun!
The wind is pretty stiff at 5-6mph with gust to 8.5mph on the ground which means the wind above 20ft is more like 9-12mph.
I just received my Gemfan 8x4 APC Style Props and wanted to test them out on this plane.
They are much stiffer than the standard Gemfan 8x4 ABS Props and they provide more thrust ;-)

Macfree F22 Smart Plane - DustOff Flight Compilation #1 (13 min 27 sec)


I haven't flown my Macfree F-22 Nano Brushless ParkJet for months, so let's throw it into the air ;-)
Some issues became apparent, my 1103 motor is on it's last leg as I used to get 5+ minutes of flight time, and one of my servos is hanging ;-(
It seems my voltage telemetry is off as well because it reports low power approx. 1 minute after launch ;-(
Well, perhaps a new servo and an 1104 motor is just what the plane needs....sometime in the near future ;-)
Oh, and sometimes you just have to argue with your transmitter, especially when it talks back ;-)

Link to this plane:

H-King Fw 190 - Glue-N-Go - Foamboard Kit (Global)
https://hobbyking.com/en_us/fw190-pp...asc=4121073648

Well, mine required a bit more than "Glue & Go" ;-(

There are links in the Video Show Notes to most of what you will need to get this plane in the air.

Here are some issues I ran into:

The recommended Motor & Prop are a bit less than optimal, I would say a 2212 1400kv minimum motor with a 9x4.5 prop.
The build instructions have a couple of things out of order, do not glue on the top and bottom of the fuselage before installing your motor mount.
The Foam Hinges were coming apart before I started the build, install some type of hinges, I reinforced with tape hinges.
The Tail Vertical Stabilizer would move when actuating the Rudder and I had to reinforce that area.
The Landing Gear should be adequate for a smooth surface but not rough terrain as they are too fragile.
There is no tail wheel, just a carbon slat, this will not work on anything but a smooth hard surface such as asphalt or concrete.
I installed a ping pong ball for a tail wheel ;-)
I used the recommended 9g Servos (HXT900) and the cutouts had to be modified.
My tail section has warped foam and so my elevator is canted.
One of the Control Rods was way too short and could not be used, you...Continue Reading

RC Tip #15 - Micro Servo Connector Confusion!

RC Tip #15 - Micro Servo Connector Confusion! (7 min 0 sec)


Well, just when you thought it couldn't get any worse, it seems we can't even standardize pins and shrouds on Micro Servos?
Yes, that's right! I found out when completing a total Brushless Conversion on the WLToys F949 Cessna 182.
I selected a Micro Low Voltage Receiver that has Micro JST-SH Pins with a 1.0mm Pitch.
Would you believe that most of the Micro Servos I came across have Micro JST-SH Pins with 1.25mm Pitch?
Yep, you heard right, apparently things aren't difficult enough in our Beloved Hobby, the Manufacturers have to use different Pins and Shrouds for the exact same size and voltage of Micro Servos!
I will explain what I have discovered and how to mitigate this problem introduced by RC Manufacturer in regards to Micro Servos.

Here is a link to the Micro DSM2/DSMX Receiver I used which has JST-SH 1.0mm Pitch Sockets:
2.4G 4CH Micro Low Voltage DSM2 DSMX Compatible Receiver Built-in Brushed ESC
https://www.banggood.com/2_4G-4CH-Mi...47791920140372

Here is a link to the Micro Servos I used which have JST-SH 1.0mm Pitch Connectors that work with the Receiver:

This is a fairly large plane compared to what I have flown thus far. The largest plane I have in my hanger by far.
The assembly is fairly straight forward so I did not include an assembly video.
The plane is dubbed a Glider and Trainer.
I don't think I would recommend a plane this large as a trainer. Perhaps as a 3rd plane.
I removed the Y-cable from the Aileron Servos, installed Servo Extension Cables and programmed it for Flaperons.
I am using a 3S 2200mah 40C LIPO (192g) for this plane and had to move the battery all the way forward to get the CG correct.
You could use a smaller LIPO if you have a camera mounted at the front.
Be sure to check your CG on this plane before flight.

I thought this may be a good candidate for our "Glue & Fly Series" Mini ParkJets.
I'm currently using a King Kong/LDARC 2205 2300kv Motor.
I'm hoping since this motor should have more torque than the 2205 and the KV is slightly higher it will provide more thrust without using more amps ;-)
Let's see how it performs.
