how hard is it to do, I am building an su-27t that is known for being able to preform this manover at a high rate of speedAbsolutely possible. There are some lower aspect planes and deltas that are good in high alpha without any fancy thrust vectoring or stabilizer systems. An FT Nutball, Flyer, and I'd imagine their delta, could all do it. Look at my Avatar. It's my own extra slender delta 3ch RET design. The rudder gives it fine control on high angles of attach(such as the "Cobra").
thanks for the helpAs far as I know, the Cobra is just a straight forward flare to a very high angle of attack. My design(and I'd imagine the Nutball and Flyer) can do more, and even turn and maneuver around somewhat while maintaining the "cobra".
At about the 1:10 minute mark, I start doing all the cobras and high alpha stuff.
Those should work, but I'm not sure it will come as natural with a tailed fighter. Tailless deltas and other low aspect shapes like the Nutball do it easier, but it is definitely possible with the planes you want to use, even in scale. You will want to have a little bit of excess thrust and a low weight, whatever type of plane you will use. To get excess thrust, make sure you got a good power plant that provides a good thrust to weight ratio, calculate your wing loading, and use a three or four blade prop, which will be a little less energy efficient, but provide the spare thrust you need especially at low speed and throttle.how hard is it to do, I am building an su-27t or su33 that is known for being able to preform this manover at a high rate of speed
They do look very similar and the wing is about identical, but the canards ion the SU-33 would probably make it a bit better choice out of the two for what you want to do with it. The canards add some pitch stability, which makes stuff like the Cobra easier and smoother.

That makes sense. Wasn't as familiar with the full scale history on that one. What I said remains though, the main difference is the canards on the 33, which help with pitch stability in high angles of attack. If you go with the SU-27T version with no canards, it should still do the Cobra, but you might need to work a little harder/won't be quite as smooth to maintain pitch stability in high alpha.the su-33 is an su-27t but it has a different designation
ok do you thank thrust vectoring can help with stabilityThat makes sense. Wasn't as familiar with the full scale history on that one. What I said remains though, the main difference is the canards on the 33, which help with pitch stability in high angles of attack.
If you have the time, resources, and skills to add thrust vectoring to your builds, it will absolutely help with stability and high alpha aerobatics such as the Cobra. If you are more of a novice or beginner builder and pilot, I'd try something easier first without thrust vectoring.ok do you thank thrust vectoring can help with stability
I'm actully going to put in a gyro and stability surfaces controled by the gyro to make it alot easier to flyIf you have the time, resources, and skills to add thrust vectoring to your builds, it will absolutely help with stability and high alpha aerobatics such as the Cobra.

im filling this plane with all the tech so it will last a long time. at least thats the hope still prototyping
I was going to say something like this, good call. If you are new, use a simulator and build and fly some simpler planes. I'd get/make like a standard basic trainer, plus a couple basic 3ch planes that can do all the Cobra/high alpha stuff you want to do. After that, build a basic prop in slot version of your SU-27 or SU-33, with a three or four blade prop and excess thrust like I stated earlier, and translate the high alpha skills you learned on more basic planes to that. After that point you could start looking into thrust vectoring and whatnot. You don't want to depend on the idea of foam air frames lasting indefinitely, especially if you are new.Two things... Usually when one of my planes acts like the one in the gif, I go pick up the bits and put them in a bag... Not saying that will be your end result, but if you are new to flying, be prepared. Carry a large plastic yard bag for bits.
All planes have a shelf life. One reason we use foam board is that it is cheap and easy to repair/replace. The cost of parts and the cost in time to build with foam is pretty low. The point being that if you fly you WILL crash. I strongly recommend you start simple and cheap with the understanding that if your first plane survives its maiden voyage, you are incredibly lucky.
Of course if building these is old hat to you and you have years of piloting experience, I am probably dipping without chips.
If you are new to the hobby, I STRONGLY recommend you question the 'last a long time' concept and instead focus on building planes you can learn on. Planes that you won't mind crashing and picking up with a bag and laughing at with friends at the end of the day.
IMO that is a much better (and cheaper) way to learn.

cat issues
Nice. That's a fairly good place to start looking at a project like this.It helps knowing your experience level. You may want to ask around, and see what sort of thrust vectoring setups are available, you will have choices between various prop in slot and straight pusher setups, as well as ducted fans. If you need advice on thrust vectoring setups or setting up things like gyro stability, I'm not the one to answer that.I am traning on a ft spitfire w/ 25% rates and have very deep understanding of flight and aircraft design. I am building it to help train with a faster aircraft, and learn some aerobatic manovers later in the futer. This plane is in the works i've only completed the nose and one wing witch i Have to remake due to some cat issues. Aswell hoping i can perfect it and release plans so others can learn off of it aswell. The tech is for stabillity and trying new things that hopfully give it a long shelf life. I chose this aircraft becase poeple can tune and change charactistics of the craft. Thanks For the Help!!!
