Previous builders of the DW Hobby Griffin complained about the tail lacking elevator authority and breaking easily because the tail boom was weak. At least one guy mentioned it being tail heavy.

The tail feathers are treated separately. They weigh 5 oz.

Modifications:
1. Installed carbon fiber strips 1/4” X 8” to the back end on both sides inside. These cost $6.99 extra and did not come with the kit. I CA’d them in place and think 5 min epoxy would have been wiser.
2. Moved the two A5 balsa side doublers forward to the compartment behind F11 former.
3. Kept the carbon fiber tube and cut a side slit for the rudder control. Cut one on top for the elevator control.
4. Reviewed the cable routing on the Carl Goldberg Sophisticated Lady plans. I matched the entry in the front of the stab and kept some of the rod exit angle. I also put graphite powder into the plastic tube to ease friction.
5. I epoxied the plastic tube in place and ground out ruts in the balsa sheeting to make the sides lay flat.
6. Had to trim 1/8” off the bottom of the right sheeting to make it match the left side. And I had to trim the front of the eppenage’s front piece to accommodate the carbon fiber slats.

The whole carbon tube slid into place. The wires were run. And everything was CA’d in place....Continue Reading

I am currently in the last stages of building a B-52 downslope glider with an 86 inch wingspan. I'm a first time builder. I'm using Futuba. S3003 servos with FYF 4CH FHSS controller what are the recommended batteries. Any help will be greatly appreciated.

What is the number one problem in RC.

In my opinion it would be brownouts on loss of control due to an inadequate power source. At least four planes that is my experience. Watching others and my own aircraft. Has not been a problem for my drones. Drones not having many or any servos for power surge causing a brownout.

This is an easy problem to fix. But because so many people think it is something other than a brownout they never do. They blame it on interference which is a rare thing with frequency hopping and binding transmitter to receivers preventing other transmitters from knocking you out of the sky like the old 72 megahertz radios could do if you were on the same Frequency.

Often all thatit is required to solve loss of control of your RC craft is a larger BEC or receiver battery. THAT'S IT.

SOME PEOPLE HAVE CHANGED OUT THEIR EQUIPMENT ALL TOGETHER AND THEN THEY SAY HEY I HAVE NO MORE BROWNOUTS. WELL THEY HAVEN'T HAD BROWNOUTS UP TO THAT POINT AND YES MAYBE THEIR SYSTEM WAS LESS SENSITIVE TO IT BUT THEY JUST SPENT OF A LOT OF MONEY NOT KNOWING WHAT THE REAL PROBLEM WAS.

I originally was a futaba user. I didn't like all the spektrum pilots who were losing control of their planes that were electric. Gas and nitro planes did not have that problem. That's because they are using receiver batteries.
I found that futaba was less susceptible but not immune to brownouts. Spektrum was more sensitive to a poor power source causing brownouts. Once I figured that out and fixed power source on all my scratch built 14 planes, thay never browned out after that. My 6 bind and fly planes never had an issue ever. That's because they were built correctly from the start.
So I know spektrum is a reliable radio. Although they are somewhat that will disagree.

Got in some more work on the Goldberg Jr. Skylark project that's slowly creeping along.

The note is written to be understandable by those who have never experienced this type of old school finishing (and maybe flash-back material for those who have!).
--------------------------------------------
Doping out in the shop...butyrate that is...

So the Skylark gets a layer of light silkspan applied to it's fuselage..."painted on" with Brodak clear dope, along with a little shaping work on it's tail cone.

This is the most "crafts-like" stage, with a lot of tissue trimming and using clear dope to bond it with the balsa, then using sand paper to trim away the excess. Makes the whole shop smell like "Model Airplane"...which, when I was kid, used to get me evicted from the front room to the front porch. Mom just didn't appreciate my version of "Aroma Therapy".

It'll get sanded and clear-coated 'till it starts to get a shine, or until I start seeing purple dust bunnies in my closed-window, winter time shop....Continue Reading

I designed the Whippiteer at the end of last year and constructed over Christmas 2019, it now has a number of flights under its rotors and shows promise. Unfortunately we have been hounded with constant wet weather over here in the UK so its not been tested as much as it should have.
Hopefully this one will be published in RCME magazine as a free pull out plan this year (its availible in the USA but under another name which has escaped me?).

Here are a few photos taken in January along with its third flight.

A build log is located on the magazine forum HERE



A few statics taken before the maiden:

Which pin-out connects to a quadcopter flight controller? thank you. Which type of quadcopter flight controller is compatible with a DLv2 receiver?
Posted by Keeshay | Yesterday @ 09:20 PM | 1,323 Views
I've finally accomplished binding my SpektrumDX6g3 to a Dragonlink v2. I've connected 4 servos, and each respond to stick input. I need to know which pin-out to solder to a quadcopter flight controller. I finally found this RC group. This has been a year long search for a simple task. Thank you for any info.

Hi all,

For the benefits of those wanting to use the K110 gyro as the flight controller, I am posting wiring diagrams showing how it is done.
The first diagram is for brushless tail, note that the 5V BEC is only driving the three cyclic servos and the K110 gyro, any BEC capable of 1.5A would be enough.

and the second diagram is for 1s brushed tail, note that the 5V BEC is driving the three cyclic servos, the K110 gyro and the tail motor so
the 5V BEC must be capable of at least 3A or better.

HINT: Beware about the quoted tiny '3A BECs' sold on Ebay, Aliexpress and Banggood. Although they advertiseds as 3A, however, for most of them, the 3A figure is the burst current for about 10 seconds. I bought a batch of 10 of them on Ebay but have to return them. Testing them revealed the continuous current is only 1.5A and even so, they got very hot to the touch. And yup, those are rated as 3A capable, which is a load of trash.

To Windy (0 min 27 sec)


WOW !!

I got up around 5.45am to try to beat the wind !
It was really quiet @ 6am
I walked out the door 6.30am ( Sunrise being just after 7am )

By the time I got to the field the wind gust was probably over 20kmh ...

Yeah , the wind has it in for me ( must be personal ! )

Anyways , launched the cub and it did on into such a wind .

I turned left and then down wind , now the cub picked up a lot of speed .

Trying to turn back and the cub was just not cutting it and rather than try to beat the wind I just cut power and landed / put down the cub a best as I could .
No damage , no nothing . Just a damned shame that it is so windy all the time .
What the heck happened to the weather ?
It's never been so windy before ! Decent days are few and far between . 2019 was simply horrendous for wind .
Go back 20 years and nice days were common place , now , rare as hens teeth !

Update :

The wind was so strong :
That when I turned left on the down wind leg , the angle of the wing pushed the cub down .
And the angle of the wing just made it hard to beat the wind , I think because so much of the back of the wing was exposed it just acted like a sail pushing the cub . It's almost Noon now and it's much calmer , but gusty .
Local airport says 15 gusting to 25kmh

I got this nice twin 70mm EDF kit from BH for $149, including free shipping,

https://www.bananahobby.com/7-ch-bli...f-jet-kit.html

The kit itself is lightweight epo and is made by Lanxiang, it has been around for a few years

http://www.lxhm.us/En/Product/detail/id/22.html

The model is 80.9 cm wingspan, whereas the original has 13.3 m wingspan

https://en.wikipedia.org/wiki/Northrop_YF-23

which gives an approximate scale of 1:16.4 .

As a result, the model is actually quite small for a twin 70mm edf (as opposed for ex. to the Su-57 by the same manuf.)

Hi everyone I have just seen what is described as a carbon Seawind and was wondering how you could tell the difference between this and an ordinary one.The owner says he knows nothing about boats but adds the model No. is K40463RS.

After hard searching for the proper bearings to adopt the sunnysky 2302 motor for a 2.5mm shaft, no joy without spending to much for one bearing. So, while digging through a bin with odd stuff, I came across some compression tubing inserts (brass and stainless steel) that is perfect for this application, The 2.5mm shaft fits perfect into the inserts. The stainless steel inserts needs little filing on the OD to fit into the 3mm bearings. The brass inserts drops right into the 3mm bearings. I also put a insert into the locking end of the motor with the flared end on the outside. The other inserts length were shortened by filing them short and the flared side of the inserts were placed on the inside. I did not put any loctite between the inserts and bearing race, but, if I need to, I will. So far, it's smooth as .....

The entire driveline of the 3mm hisky hcp100s can also be adopted to the k110 to avoid what I did with the inserts. If I didn't find the inserts, hcp100s driveline would of been my choice. And it's probably more robust.
