Yep!! i did that already all surfaces are correct . Hmm i notice that about 60-70% it wants to hover!

It hovers at that point of 60-70%.
Less than 30 then and full power right?? until it gets some lift on its wings? am i right??

Yes go full power for take, like he said about 30 degree angle up and give it a fairly hard toss and once you get air under the wings you will be rocking.

Okay, last point, you need to practice how you are going to hold the plane(underneath or on top) left or right hand etc., and then throw it. Make sure your hand doesn't slip or slide when winding up. Just be firm.

A suggestion: After many years, found that if you launch with the right hand and then go to aileron/elevator control. Here is what i do with the left hand. I grab the left hand and put the 4 fingers under the radio and then take the thumb and put it on the yoke so by pushing down it holds the radio as well as you are able to control the throttle from 100% to off(if it is going to crash) . So all you do is move the thumb forward or backward to change the engine speed. As you release, the right hand comes down to work aileron/elevator and the left hand shifts to cover rudder/throttle.
You will know quickly if the plane is going to make it or not when you release. It will come natural after a bunch of throws and it is always better to kill the motor if it is going in. Just my way that there is no time delay with the throttle.
Will explain to you how to reduce spooling up time which can save your edf'/plane at low speeds.

Last point, make sure you stay focused from release time to landing. Have fun !!!!!!!!!!!!!!!!!!!!!!!!!!!!

Just got my matching edf's running for my wart-hog. Now need to put them in the cowling.
I like to design and fly unique planes.

That sucks and I know the feeling. More then likely not enough thrust.

Sorry to hear that !! I have had my own dud projects... frustrating but I've learned tons about what will ultimately work. Don't be discouraged but press on and continue to glean from the experience here.

So sorry to know the unexpected event happened. I believe all of us had experienced it. If you have videos, it would help you to analyze and have some guesses why it happened. You will get good suggestions as well from many good people here in the forum.

Just kindly remember, failures are not stopping signs. They are guidelines for success

This is a very bad feeling my friend....i can't understand....i have to try again to build something else...i don't have the courage to build it again....i want to try for the Mig-29....smaller and with the equipment that i have i think it will be better....what do you think for that range of the weight that my equipment has?? an opinion??
THIS IS THE WEIGHT WITH BATTERY
Includes
2x Motors with thrust tubes and TV System
1x Battery
7x servos 9g
Servo wires
2xEsc 70A Mystery Cloud
and the cables for the connections....






AND WITH OUT BATTERY



What do you recommended guys i want to build the Mig 29 with those units!

To be honest....i didn't believe that this will fly....i didn't have the confidence to believe that....it was over weight so....with 2.6kg ready to fly and with that motors to produce 3.28kg at full throttle....there is no way for this crap to work....i just cant understand....the truth is that this Guys here are great!!! all of them!! very helpful and always gives you a piece of advice! that's great and i want to THANK everyone in this site!!
I have some photos of shame...but just a moment ago i have completed the (destruction) of that plane....Now i want to focus to the Mig-29! Smaller and better i think...check at my equipment if you want to tell me your opinion for the weight....

Welcome to the world of EDF's. Now you see why not to many fly them. Weight, thrust, spooling up etc. is a different game.

As others have mentioned, please get a video camera so you and the group can give you suggestions. Showing it in slow motion can tell exactly what is going wrong.

I am going to suggest another approach. Start off finding a model that is super, super, light, use only 1 EDF, and gain some experience with EDF's. Flying an EDF is different than props, Once you learn the rules such as spooling up, no sharp turns, how to launch, etc., than go for the dual fighter jets.

Don't get disgusted, go for it, and you will succeed. You started with too much on your plate. Trust me, we all learn from that rule. My moto is "KISS", which is needed with EDF's.

How much would it weigh without the TV assemblies?

The first ever model that i flown was the F-16 Skyangel 50mm EDF (i still have it in one piece) this is the model that i start with Rc flying etc....After this one i took the Super Decathlon and after that i build the Viggen with EDF 50mm once again and now i did the simple storch etc..... Thats what im saying is that there is no an issue that i cant fly a model or land it or whatever! is that i post here some infos so someone that knows something more about any specific model to help me find a way out!
I don't have any problem on how to hold or launch any plane....i just want some measurements about my equipment that i have and what is more right to with this this equipment so my work to pay off....!!!
EDF is the A for me and with those i start flying etc thats what i want to say.... i just want to build something big so i can enjoy it more than the small ones!.... Next Model is the Mig 29 with those equipment that i have.....if you can to help me is more than welcome!

That's a lot of weight right there. you should try your next project without them and just have thrust tubes.
