Two rubber bands looped over the throttle stick will save some fingers.

Probably last year, I bought a Blade Inductrix FPV from They threw in a sticker, and a white 10 degree camera mount. So what I did was remove the yellow dome. In the dome is the camera and vtx. It is held in there with four tiny screws in order for the camera to come off. It does come off easily, but you need a micro phillips head screwdriver. So removing the dome shaves off 1.5 grams of weight, which is a big reduction in weight for these ultra micro quads. My next big thing to do is upgrade to more powerful motors.

Out of necessity, I've had to learn how to use Betaflight. When it's working, it's great, especially when the quadcopter I'm tuning cooperates, and it has a readily accessible re-boot button. It's probably because I have a four year old p.c. that causes the drone to lose connectivity with Betaflight. I hate that. I bought a Moskito 70, configured it the way I wanted it, and then, it lost connectivity via the USB port. The port works fine. Something in the board got messed up. Per a friend's instructions, I found the reboot solder terminals and tried to reboot it. It didn't work. To this day, that Moskito 70 from GetFPV is a brightly colored brick, and I regret having fallen for something that is lacking in serviceability. The drone market is loaded with Spektrum and FRSky compatible receivers. It's an absolute must that it be configured in Betaflight, or Cleanflight, or whatever else is available. That's great if you like messing around with firmware. I'd rather be spending my time flying. Give me something that's bind-and-fly from Horizon Hobby instead.

I posted this on the Betaflight Forum, but never got a response. I hope somebody can help.
I managed to flash the latest firmware to my KingKong 90GT, using Betaflight. Before that, I bound it to my DX9 radio. I have two major problems.

One is the Receiver Tab on Betaflight . The colored bars that correspond to the stick commands for yaw, pitch, roll, and throttle won't move with the stick movements on the DX9 radio.

The other problem is the quad doesn't respond to the DX9 when I arm the esc's. It's already been bound. I re-bind, and still no response.

I wrote down the configurations that I used on Betaflight:

Serial receiver provider: Spektrum1024
Receiver mode: Serial-based receiver (Speksat, SBUS, etc.)

Ports Tab:
UART1 enabled, MSP (115200)
UART3 is serial rx

Receiver Tab:
Channel Map: TAER1234
RSSI channel: 4
Interpolation: Auto
Deadband for Yaw & RC Deadband = 3

Arm @ Aux1 (range: 1500-2100)
AirMode @ Aux2 (range: 1725-2100)
Angle Mode @ Aux2 (range: 1375-1600)
Horizon Mode @ Aux 2 (range: 900-1275)

The manual for this quad is virtually useless. Had I known, I would've stuck with Blade quads; at least they have manuals and video tutorials.

I've searched the web for info on the type of micro sd card that you can use on this. The only thing the manual tells you is it needs a class 10. The Tower Hobbies catalog number for their micro sd card is LXFSFA. It's a 4 gigabyte card. I tried using a 64 GB card, and the monitor will display "card full," then disappears. I will try to use a 32GB card when I get around to ordering one. I like the monitor. It has a search button (B) that you press for 2 seconds, then it goes thru all the channels and stops at the strongest one. Otherwise, you just keep pushing the CH button to go thru all the channels.

Why have a monitor, when you already have goggles? If you have a spotter, or a friend with you, it's very convenient for them. And if you are just testing out a new quad line of sight, it's nice to be able to glance down at the monitor and get an idea of the camera angle and field of view.

By request, size comparisons of the Inductrix, Inductrix FPV, Moskito 70, and Fatshark HD3 goggles.

I hardly ever buy anything at physical hobby shops any more (stores you can walk in to) because a lot of (not all of) these shops are attended to by very rude salespeople. I walk in, and they immediately think I don't have a lot of money, and/or I don't have good credit. You see, that's the problem, these days. You are automatically profiled according to what you are. No, I'm not going into the race thing. If you can read this, you are old enough to know what I'm talking about.

I buy pretty much all of my hobby supplies online or mail order, because they can't see who you are and so, they can't profile you. Listen, I work for a government agency. You would not know that by looking at me. My point is, you can't judge people based on who or what they are.

I don't know about you, but I'm tired of EFlite, FMS, Tower Hobbies and everybody else doing the same old thing, year in year out. It's always the Mustang, the Thunderbolt, the T28, Spitfire, the Corsair. Gosh, can you guys make something else besides those that I mentioned? People are gonna tire out flying the same ol' thing.

These are really good servos at a very affordable price of around $6.50 to $7.00 each. I get them here:

One FYI: These servos do not test well with the most common servo testers, like GT Power brand. It won't work. You need to test these servos with the receiver that you will be using.

Realflight RF-X is a big disappointment. The video quality is a stop-motion, jittery mess. One other RCGroups user said you need a high-end gaming card or gaming pc to run it.

If you want realism, stick with Realflight 7.5

This plane is near-perfect. All I did was add carbon-fiber reinforcements to the rear fuselage/horizontal-and-vertical stabilizers.

For those who build epp foam aircraft, I found a new brand of Goop glue on Amazon. It's $6.33 right now, for a 3.7 ounce tube. There are other vendors on Amazon, but those who have Amazon Prime can get it for the above price. It's the same thickness as Goop. Welder's glue is a thinner concoction. Here is a link:

Let's make this the quickest review/comparison/article...
Which is better, the Twisted Hobbys Veloxity, or the Twisted Hobbys 39 inch Crack Yak?

I fly both. The 39 inch Crack Yak flies better overall.

Multiplex needs to upgrade their Funcub.

They should start with the same basic airframe, but make the aileron surfaces much bigger, along with a larger elevator surface and larger rudder, with 45 degree throws all around.

The v2.0 Funcub should also incorporate a 4s motor & esc.

This should fill a niche created by the gas-powered 3D Hobbyshop Bigfoot.

As a newb in 2004, I looked at a foamie profile plane and commented on how "ugly" those things were. That was wrong to diss anybody's plane, and I regret saying it. As I became more proficient, I got one and realized how much more technical it is to fly it, as compared to a warplane.

With profile planes, I learned that this design is the absolute lightest method of making a flying machine. If you make a full-body airplane, you are adding the weight of a rounded fuselage and the internal bracings. With a profile plane, the bracings are minimal, and the surface is also minimal. It is much lighter. The wings will carry less weight. That is ideal. With 3D aerobatic planes, the closer you get to a 2-to-1 thrust-to-weight ratio (or better), the performance that you will be getting out of your plane will be like an epiphany: "all this time, I've been flying pigs!"

Yeah, so the profile design gives you the lightest possible all-up weight, while still maintaining the flight characteristics of a full-bodied airplane, while keeping the cost and construction time at a minimum.

By my recollection, I began in 2004. It just blows my mind how time flies. I'm 54 years of age, and minus the aches and pains, I still feel like I'm 30.

It's interesting to look back. I was very much into WWI & WWII combat aircraft and trainers, like the Fokker DVII, P51, P47, T28, PT17 & PT19. I still have a T28, lightened up so that I can use a 1000mAh 3s lipo and an AXI 2217-16 brushless outrunner. I fly it for 6 minutes, but it will stay aloft for 8.

After about three years, flying around in circles became monotonous. I started building & flying aerobatic depron planes. Epp foam came out, and I bought some and made a couple of planes out of that. Next thing I knew, I began flying flying balsa aerobats. When I saw how much nicer and more stable the aerobatic planes were, going back and flying warbirds was like work. Even the heavy foam warplanes felt like flying pigs to me. They just became boring to me. And I noticed that some of the people I flew with disappeared. They didn't learn new things, so it got old and they quit flying. I understand that the advanced flying skills are too much for some people to process. It was for me, but I worked on it constantly and picked up more skills so it stays interesting that way.

But then, don't get me wrong, there are days when I just want to fly graceful and slow. It's good to mix it up.

I've heard it more than once at the field: "He might as well buy a helicopter if he wants to hover his airplane."

There is a purpose for hovering: Learning & practicing orientation while the airplane is torque-rolling.

You see, 3D pilots are far more advanced as far as orientation. They know how to control the aircraft when it's inverted, upright, inverted flying away from you, inverted flying towards you, going up with the belly facing you, and going down with the belly facing you.

3D pilots are far more aware of the airplane's stall characteristics, and during post-stall. They are more in tune to their plane's weight and wing loading.

And lastly, 3D pilots' reflexes are sharpened by practicing hovering. They are not really trying to imitate helicopters.

This thing is the best. My car has a USB port, but if you don't have one, just get a cigarette lighter USB port and you're in business.

Recently, I bought a cellphone charger. It has a USB charging port on it. Guess what? I can put my EFlite 1s charger on it. That's pretty handy.
