For those of you interested in higher tension gimbals, it's very possible to do a mod with the included springs. I know UGFPV are looking to put out a higher tension spring kit but honestly that would be such a PITA to change and require some gimbal disassembly. The method i used is simple, the springs are attached to a sliding column that is moving up and down inside a channel via an M2 bolt. The M2 bolt that move the spring tensioning part are by stock actually at their full tension and topped out by the head of the screw. Now if the screw itself is 2mm longer then you have 2mm more travel height for the spring holder to move up and that 2mm made the world of difference. So if you want to do this get some M2x12mm bolts and replace the M2x10mm ones. Best of all this requires no fiddling with removing springs or disassembly of the gimbals. I've also checked full travel and no fouling on back part of the TX case, despite sitting slightly more proud than before.

In the pics attached below you can see the original screw phillips head at its max and how low the spring tensioner is sitting. The hexhead bolts ive used have a finer thread for finer adjustment and hexes are just nicer. Because these bolt heads are bigger i did shave away a little corner of the hall PCB so it didn't foul there but there are absolutely no traces in that corner so its nothing to worry about. Just carefully dremel or file away if the bolts you use have larger heads like mine. If you go with low profile heads you likely wont need to bother doing this at all.

Finally a small flight video on my 6 inch quad with crossfire running 250mw mode on the Nirvana. I will say the end to end digital is noticeable and i love the precision, however without the extra gimbal tension i found that to result in a twitchy feel. Now this is set up how i like it it feels great.

Hope some of this is useful. NJ

I have a JXD 509G drone. I want to put a pan and tilt gimbal on it. The one I have has two SG90 servos. I was hoping there was a way to connect it to the drone that I could use the trim buttons to control it. Any thoughts or ideas would be great.

10 Pairs AVAN Rush 2.5 Inch Props 3 blades Propellers CW CCW for Emax 1106 Motor Lipo 3S to 4S Babyhawk FPV RC Racing Drone Quadcopter Model
https://www.xt-xinte.com/10-Pairs-AV...l-p548986.html
The Emax Avan Rush propeller 2.5x1.9x3 was designed for Babyhawk Race 2.5 inch conversion kit to maximize performance and flight time. This propeller is matched to Emax 1106 4500kv for 4s or the Emax 1106 6000kv on 3s. A true 1.9" pitch throughout the blade gives a linear control feeling across the throttle band while still achieving high speeds. This allows for ease of flight and more precision. With a special PC blend the Avan Mini weighs 1.25 grams. Utilizing thicker airfoils greatly increases durability and stiffness. Most of the weight is centralized near the hub creating a low moment of inertia of 1.24 grams*square centimeter which in turn makes a very responsive prop.



The Avan Rush was designed from the ground up starting from design constraints such as RPM, air speed, and required thrust. From these constraints aerodynamic models were built to predict performance and to design the blade shape. Highly cambered airfoils were used to achieve high lift coefficients at high angles of attack prolonging stall. This allows for a higher blade angle while still remaining efficient. The cambered airfoils also allow a greater flight envelope making for great low end responsiveness while still being able to achieve high speeds.



A special Polycarbonate blend is used to achieve high durability. This material is incredibly tough and ductile to resist fracture in high impact crashes. A thick blade root was designed to further increase this durability. Our injection mold process is optimized to reduce bubbles in the plastic to increase the strength of the propeller and to maintain superb balance.



AVAN Rush 2.5 inch prop (2xCW 2xCCW) 1 set kit



Geometry:

2.5 inch diameter

1.9 inch pitch

3 blades



Inertial Properties:

weight: 1.4 grams

Moment of Inertia: 1.24 g*cm^2



Packing list:



10pcs*CW 2.5inch propellers

So I received my servos/reciver part and my prop and pushrods today and installed all those parts except the prop. I also stretched the wings (I actually couldn’t get all of the wrinkles out but I tried my best to have it get as tight as possible.)
I then painted the main wing, horizontal stab, elevator, vertical stab, rudder and landing gear doors. Then mounted the main wing to the fuselage!

Tomorrow I will cover the rest of the fuselage and connect up the elevator and rudder to the pushrod assembly, and finish putting on the rest of the parts!

RC Review - XK DHC-2 A600 Beaver Airplane

RC Review - XK DHC-2 A600 Beaver Airplane (25 min 13 sec)


***Update Note: Due to the fact that this plane is made from EPS Foam and is quite brittle.
I do not recommend this plane as a Trainer or as your first plane.
I would recommend this plane as a second plane once some flying skill has been attained.

This little airplane seems to be well built and is only approx. 90 grams AUW (All-Up-Weight)
The assembly was very simple and minimal.
It can carry a Micro FPV System and fly via FPV for approx. 5.5 minutes with the 2S 300mah 65C LIPOs I purchased for this plane. Much Fun!
It has two modes, one is 6 axis gyro stabilization and the other is 3D, which appears to be full manual mode.
Manual mode should only be attempted with calm wind.
The plane has a great flight envelope, and can fly fairly slow without stalling which makes it easy to land.
It also has a normal and more responsive rudder setting according to the manual.
This plane has a very high fun factor! I really love this plane.
The EPS Foam is a bit brittle and not nearly as durable as EPP Foam or EPO Foam.
I plowed this into the ground in manual mode on my maiden flight and nearly took the nose completely off ;-(
There are plenty of spare parts for this plane as well.

Here is a link to this plane:

Not long ago, I put out some feelers in the classifieds for a Harbor Freight P-51. I'd always wanted to convert one to brushless power, but even with a famed Harbor Freight discount coupon, the $100 price tag was a bit much, especially since all I wanted was the airframe.

Enter RCG user Jimmy Dixon, aka "jdixon" who had not one, but two Mustangs up for grabs.

The first was a complete Ares P-51 less its motor and props. My local HobbyTown franchise was unable to get the parts, so I found them on Amazon. Pictures to follow; it's untouched cosmetically. It is one of the sweetest flying small models I've ever flown and should anything happen to it, I'll buy a new one right away.

That second P-51 was a well used Harbor Freight version, complete with a handful of spare parts and a complete if damaged airframe.

My original goal was to upgrade the HF version and do it up like Bunny, the Tuskegee Airmen tribute P-51 at the Palm Springs Air Museum. That's exactly what I plan to do as work progresses on the model as shown below.

A 1000Kv brushless outrunner and an E-flite stick mount adapter along with a 20A ESC are lined up and ready to go once it's finished. A visit to the air museum is in order once Bunny returns from the Reno Air Races. From there, photos will be on their way to the one and only Callie Soden of Callie Graphics for her peerless custom decals.

My first plane was a HobbyZone SuperCub that I got for Xmas several years ago. I have crashed and bashed it several times over the years so outside of the basic foam pieces it does not much in common with the original plane. It basically has become a test bed for developing/testing out building techniques, etc.

I have modified the wing so that it bolts on rather use rubber bands, replaced all the electronics and added ailerons, flaps and built floats for it.

I thought I would create this thread to document some of the changes I have made in the past and moving forward.

Edmunds Road Walk - 3DR Solo (OpenSolo v3.0.0) [GoPro Hero4 Black] (3 min 42 sec)


Testing out my new Freedom360 ND8 filter on my GoPro Hero4 Black on my 3DR Solo.

This video is a great example of the need to know your settings, and to know what equipment is appropriate for what environment.

Problem 1) Settings for yaw/pitch/roll were cranked up to max. Twitchy, and not suitable for smooth filming.
Problem 2) Walking while controlling (for me) made it very hard to maintain smooth stick inputs.
Problem 3) ND8 filter at dusk was a stupid idea, and pure laziness made me keep it on knowing full well that the lighting was not appropriate for it.
Problem 4) I did not have my GoPro ISO-locked, so the ISO was swinging wildly to keep the frame brightness consistent, degrading image quality severely.

In short: An awful video. Don't be like me.
