We've come across at least two people who started learning how to fly r.c. aircraft with our help. One of them was a businessman. He started out as being like one of the guys, and was affable and down-to-earth. In a few years, he progressed out of the beginner phase. Because of his resources, he ventured out into gas-powered planes. He got plenty of help from his peers. I won't get into that, because most of mine understand what I'm talking about. His ego grew, but his skills were the same. He could afford the hundred-fifty dollar servos and the couple of grand price tag planes. Now, he comes by, silently, and with a very smug look on his face, looking down upon our electrics and ultramicros. I can see a hint of disdain in his face that he can barely hide. He didn't even fly today. He just came to talk with his gasser friends. As for us, we've been flying since dawn, and it's already been three hours, and six flights each. Nobody talks to him anymore; only his gasser friends are worthy of his company. I often wonder why he even bothers to come to the electric field. To look down on us? Perhaps, but that's not our problem, that's his. That's his delusion. We notice him, but we don't acknowledge him at all. Once, he came by and I brought along my 34 inch wingspan WWI biplanes, and he scoffed at them. I told him I don't come for ego; I come to fly and enjoy what I do. I felt sorry for him, because I see that he is developing some kind of dementia in his old age, and he probably won't enjoy his intermediate flying skills much longer. And I was sadly mistaken, that he was a quality human being. He is not. He didn't come to fly. He came to plump up his ego.

This is a 42.5 inch wingspan night flier from Hobbyking. The wings are very rigid, because of the strips of LED's across the wings. Those LED's are held in long strips of fiberglass pc board material, and that's what makes the wings so rigid. The lights are red and green, which is right for green; red for left. It's well thought out, because if all the lights are the same color, you can easily lose orientation on which is left versus right if you are inverted. Hobbyking solved this by putting blue lights on the bottom of the plane. And when the plane is coming towards you, the preponderance of white LED's becomes apparent, and so you know it's coming towards you.

FYI: The center of gravity (c.g.) is measured from the nose of the plane. That can vary a lot, depending upon whether or not you're using the spinner, another brand of spinner, or no spinner at all. So I took a measurement from the leading edge of the wing at the exact center: It is 64mm back from the leading edge of the wing at the center of the wing. Hobbyking's manual states that it can vary + or - 5mm. When using 3s 2200mAh lipos, I had to add 1.5 ounces of lead weight to the nose. I put the lead weights inside the cowl.

Another FYI: You do not have to glue the spinner (the nose cone) over the prop. It is held on by friction alone. You save money when you don't have to tear up the spinner to replace a broken prop.

Here is a link to a video, showing what the plane looks like lit up:

I decided to fly mostly ultramicro aircraft. I won't need to buy a van. When I retire, I will be going around in a regular-sized automobile that gets good mileage. I've flown big, and it's a lot of work taking them apart, putting them in the vehicle, and then re-assembling them at the field. After a work week, I'm exhausted, and I don't feel like working on another thing on the weekend. I just want to fly. With bigger aircraft, I can only bring one or two, because I don't like stacking them one on top of another. It puts dings and scratches on the aircraft, which to me, is unprofessional. I've been flying since 2004 (not 2007), and I've gathered enough experience to say, with all honesty that flying skills are a big part of an airplane's performance. It's not how large an aircraft you're flying, though a giant-scale has its own unique flight characteristics. They fly "big." Generally, the wing loading of so-called large scale aircraft is superior to any parkflyer or ultramicro. With ultramicros, you can bring (and thus, fly) more than a couple of aircraft in a day. If you bring your ultramicros in their boxes, you can stack them, and bring as much as your car can carry. Today, most ultramicro aircraft have some kind of gyro stabilization. Eflite calls it AS3X, which comes with a beginner mode called SAFE. With AS3X, these aircraft are a lot more stable, and some people liken the feel to a much larger craft. I just enjoy flying them, and I prefer small field flying. And storage, well, keep the boxes, if you have the space. Or you can hang them in the rafters, or the ceiling. You can own literally dozens of ultramicro aircraft, and not take up a lot of space. Yeah, so I think I've convinced myself even more. The future of RC Flight is looking good in the ultramicro realm.

If you don't care for Betaflight configuration software, you don't care to be limited to racing, and you just want to fly, the Rise Vusion is nearly perfect for you. There are some very important FYI's for the videographers out there, who want to video their flights. First, the Vusion takes micro sd cards up to 32 gb only. Secondly, you must format the micro sd card to FAT32. ExFAT32 will not work on this quad. Thirdly, the onboard video camera (DVR, or digital video recorder) can start "filming" even before you start the motors. It can keep "filming" even after you stop the motors. Fourthly, remember to stop the filming, and let the DVR catch up with writing the video files onto the micro sd card. I wait for 10 seconds or more, before I pull the plug. If the dvr is still writing the video files to the card, and you pull the plug, you lose that video file. Lastly, the video files are 1280 x 720 in size; and they are .AVI video files.

Spitfire Mk IX ...This is the Parkzone ultramicro Spitfire Mk IX. I bought this several years ago. When I first tried to trim it out, I couldn't. I later found out that the center of gravity was incorrect. It was extremely tail-heavy, and barely avoided crashing it a few times. That was the design fault of Parkzone/Horizon Hobby. I finally got around to fixing it, by adding some lead weight to the front of the aircraft, inside the intake below the propeller. It is the first 1s lipo powered Parkzone ultramicro to have AS3X stabilization. It didn't stay in the hobby marketplace for very long, and it was quickly discontinued, and I think I know why.

As you might already know, Foam Tac is $9.99 for a two ounce bottle. There is a less expensive alternative: Goop II Max. The makers of Goop II Max claim it resists yellowing and cracking, due to ultraviolet rays from the sun.

Goop II Max is $7.90 for a two ounce tube, compared to $9.99 for two ounces of Foam Tac.

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'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.

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.
