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 incorporated 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.

I've been searching the internet for information on how to set up a gas plane. From what I've been able to gather, I drew up some diagrams.

I finally got the c.g. right on my 51 inch AJ Slick. I just kept moving it back, which required multiple tries. I think I flew it and landed it at least six times, bringing the battery back until it flew level inverted as well as upright. I was going to mark the c.g. at the wingtips, but after a hard maneuver, the canopy came off. I spent a couple of hours looking for it, but could not find it.

As it is now, the airplane models in Realflight "feel" floatier than in real life. In the Realflight sim, they are less likely to tip stall or just plainly fall out of the sky from insufficient power. The planes feel less twitchy and more forgiving, even when you dial up the physics/realism. However, the roll, pitch and yaw are right on. Even the torque roll is right on.

Realflight has helped me a lot with 3D moves and aerobatics in general. I don't think I could have mastered even basic 3D without Realflight.

The most realistic models are the Twisted Hobbys Crack Yak, the ultramicro Beast biplane, and the quadcopter that looks like the DJI Phantom. I can't comment on the giant scale 30cc, 50cc, and 100cc Extra 300's, 260's, and SBachs, because I have never flown the real models.

The next major development would be even more realistic physics. A lot of that probably depends upon the computer's processing speed and maybe even improvements in the RAM. I'm not a computer expert, but I'm sure that's what's needed.

I wish Realflight was more user-friendly in terms of being able to move stuff around in the flying field. Adding, removing trees, clouds, cars, etc. should be like a click and drag with the mouse. And I wish that being able to design an airplane would be just as user-friendly, so we don't have to ask others to design planes for us, or to emulate an actual plane in the sim environment.

Radio-controlled radios aren't anything new. It has been around longer than I've been alive, and I was born in 1961. The first time I have heard of and seen a radio-control transmitter was back in 1973. My Dad and my brother; we would go around Torrance, Hawthorne, Lomita, Carson Mall, and Long Beach, looking in various hobby stores at model planes. Back then, I built plastic model planes (static display airplanes), flew free-flight balsa models, U-control Cox & Testors planes and model rockets. The first time I've ever seen radio-controlled airplanes flying was at a vacant field behind the Carson Mall. This was back around 1973 if I remember correctly. Some people were flying what looked like Ugly Stik planes. I was hooked, vowing to get one when I could afford it. Radios back then cost $300 and up, and that was a lot of money back then. We were at TQ Hobbies in Lomita (?), I think, and yes, $300 & up for a Kraft radio. I'm sure it came with servos, but still that was way more than what we could afford. I remember Futaba was considered the best, and to many, it still is. I was smitten by the gliders that flew out of Point Fermin in San Pedro, CA. I also saw them flying off of Bluff Park in Long Beach. My dad said if I wanted, we could save up to buy a glider and radio, but it would take maybe a year to get enough money. I knew it would have put a big strain on our finances, so I told him, no. And besides, I did not know how to fly r.c. If I...Continue Reading

After the automatic updates to my pc, I did not know that somehow, the NVIDIA video software had turned on the 3-D function for 3D glasses.

So what happened is that when Realflight is on, I saw double of everything, including double airplanes.

I went into the video card setting in my pc and didn't find anything broken. Then it occurred to me that maybe the 3D glasses are on. I don't use 3D glasses, because most programs don't have 3D capabilities.

In the NVIDIA settings, I found the enable/disable switch for 3D. I turned it off and went back to Realflight. Everything was back to normal

And best of all, my pc didn't overheat anymore. When it overheats, it shuts off.

Now Realflight runs fairly cool and sometimes warm in the pc.

In this blog entry, I am not instructing anyone to do this; nor is this a tutorial on how to go about it.

With the DJI Phantom 2 battery, you are left with two options: buy an AC charger from DJI, or buy their car charger. Both chargers cost a hundred dollars. They aren't really chargers; they are 12 volt power supplies.

The DJI Phantom 2 battery is a "smart battery." It has its own charger inside. It takes 12 volts DC and the internal charger does the rest.

The problem is finding a plug that fits the battery. Venom makes a set of plugs for Deans, EC3, and others. One side of the adapter plug has rounded nubs, so reversing the polarity is made that much more difficult, which is good.

I made this adapter, so that I can charge at the field. And at the end of the day, I use this adapter to discharge the battery to storage charge level.

I just found the perfect tailwheel assembly for parkflyer planes. If you fly the Tower Hobbies F6F Hellcat, you know it could use a much more durable tailwheel. Well, I've found one from Hobby-Lobby online. It costs $4.79. The photos show what it includes and nothing more. The wheel itself is made of metal with a rubber tire.

If you like to build and fly epp planes, you would know that plain old c.a. is okay to use, and Welder's is one of the best choices to use for epp. But did you know that Goop is almost the same? The only difference is that Goop seems to be thicker than Welder's. This is what both glues look like in their tubes:

Re-trim not needed, even in a day that saw 20mph + winds. Using an EMP 10x7 prop, my static run-up tests show 28.88 amps peak @ full throttle, producing 310 watts. At half throttle, the motor is drawing 12.22 amps peak, and producing 136.8 watts peak. After a 4 minute test flight, my 2200mAh 30c 3s lipo (GForce) had 3.99, 3.99 & 3.99 volts. I could have flown the T28 another 2 or 3 minutes. I set my timer to 6:00. The plane "feels" lighter in the air and responsive, without feeling "out of control." I like this setup the best.

This motor's been used by Bob (rgthd007) on his Fun Cub, spinning a 13x4 prop (!) and a 40 amp esc. Now, the Hobbyking website lists the maximum amps at 22, but in reality, the max is 32 amps. Bob did a power test and here are the results: at full throttle (13x4 prop) the motor is drawing 29 amps. At half throttle, the motor is only drawing an amazingly small 2.10 amps/25 watts with the same 13x4 prop! Maximum power at full throttle is 311 watts.

This is the plane that flies when it's too windy to fly. Nobody except a few
3D guys and jets show up at the field when the wind is blowing. My MS Composit Mustang is all-epp except for the rudder and horizontal stab, which are made of a depron-type foam. The fuselage is 1 inch thick epp. This Mustang's motor is from a Sky Fly Max plane, putting out 27 ounces of thrust with an 8x4 prop and 1800mah 3s lipo.
The a.u.w. for the P-51 is 13.75 ounces with the 1000mah 3s 11.1v lipo.

The rc hobby plane market is just full of cheap, cheesy products that could barely fly, or if it can, will only last a few flights. Now, one of my favorite planes are the Cessna high-wings. High wings in general really get my flying interest up, whenever I see one up above.

I was looking for a Cessna 172 or 182-type of park flyer; one that will fit inside my small car. This limits me to a maximum 40-inch wingspan or less. Add to the equation the need for a great-handling, high-quality, good-looking, and reasonably-priced brushless-powered airplane, and it's not that easy.

Luckily, I was browsing Youtube and came across a review for the Gravity Hobby Cessna 182. The reviewer gave it a favorable rating. He just kept saying how nice it flies, how good it looks, the battery compartment, and motor. And I was pleased to find out that the wingspan was only 35".

I love this plane. I never thought a foamie could fly like this. It flies like the large PZ T-28 Trojan.

A photograph of my Cessna is attached. I hope more people would find out about this plane.
