I don't understand why Deltas aren't more popular than they are, the Freewing Mirage and the SU-35 are my favorites and the Deltas are easy to fly and can almost harrier in on landing. There's so many Deltas that could be done like the SAAB Gripen and Viggen...I would also love to see the Freewing Eurofighter released in a V2 EPO version.

I would love to see a Saab Gripen! I have never flown deltas before, but want to give them a try. They seem to need a longer runway. The Eurofighter Typhoon is one of my all time favourite planes, but a fellow rc pilot has one and it has rotation issues on our field. Short length grass field. suggestions on a good first delta? I fly off of a relatively short grass runway (MAX 180’...150-160’ for takeoff would be best). I do own the FMS Yak, F-18 and BAE Hawk. I have also flown the FMS Viper.

Deltas set up correctly are easy to fly.
Set up wrong they are a crash waiting to happen.
Since they require a different CG than a "conventional" aircraft, and people are not familiar with the difference,,, they get set up wrong often.
They require about the same runway for the same weight and wing area aircraft with the same power... if they are set up for the correct incidence to the ground.
In some ways a delta can be easier to fly than most trainers if CG is slightly forward. but acceptable CG range is very small compared to the potentially large acceptable CG range for a "conventional" aircraft.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.
current planes from 1/2 oz to 22 lbs

These two jets are ideal for flying from short fields.

Been clamoring for a certain Delta for a while now.. They have such unique flying characteristics and love to slow down at high AOA. Would definitely be nice to have a few more choices. I’d particularly love to see a few of the American and British Deltas. The F-106, B-58, XB-70, F-102, Sea Dart, and Avro Vulcan to name a few. All beautiful airplanes, and very under modeled compared to the standard Euro canards.4 Photos

I love deltas. The Freewing 80mm Mirage was my idea years ago, based on my love of the CARF Eurosport, FlyFly Mirage, and Gaui Tigershark Delta. All of these wonderfully in their own ways. A Vulcan, Gripen, Dart, Skyray, Draken, Horten, or almost any other delta would be welcome in my personal hangar.
From an engineering standpoint, at least with single engine deltas, there are many efficiency advantages to be explored. From a sales standpoint, though, I wonder if visibility is a perceived challenge, or the different power curve or handling. While to some of us that see these as exciting changes of pace to traditional jets, to others these are barriers to entry.
For best way for someone in that boat to see if a delta is something they'd like or not is to buy an existing delta on the market and try it out.

The canard surfaces become nearly useless for scale models. They still act a bit as leading edge slats, to help delay stall, but that can be a two-edged sword since they are acting at wing root.
Delaying wing root stall means you stall wingtips first and that means snapping over and probably entering a spin.
Failure to recognize this characteristic would lead to unexpected sudden snap straight into the ground on a nose high approach and leaving you wondering what the hell caused your airplane to become confetti.
Yes, you can do a high alpha approach... but 1 degree too high is fatal.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.

Part of a flight report by a clubmate about his Gripen (non movable canard) flight on Monday. It was amusing to watch as he flipped the plane in the 12 mph wind and it got stuck at about a 60 degree AoA as it slowly descended vertically, with no apparent forward motion, to the cotton field. Plenty of time to holler advice that didn't work before the slow motion crash. :)
The only issue I had was on the 3rd flight.... decided to flip the Gripen even though the thought of "wouldn't it be hilarious if after all that work I crashed the damn thing" had *just* gone through my mind. Well, I flipped it and it got stuck in a high-alpha. Not enough power to pull out, and not enough forward airspeed to get the nose down. So it pancaked into the cotton at a relatively low speed. Found a small cotton stalk had punched through the wing and made a very small hole (easily repaired) and I stripped a servo... that was it. I got very, very lucky.
