You're wrong. If it was a special technique from Minato, they wouldn't talk so vague. Also, it seems that FTG doesn't have any disadvantages / risks to the user, additionally you don't need the fox' chakra for it. Naruto, as beeing half Uzumaki, has a large amount of chakra by nature, so why he needs the kyuubis chakra for it?
Minato's wish was that Naruto can controll the kyuubi in the course of his lifetime (to use the power and saving the world from that villain Madara). Minato said this here:

To use that power, he needs to learn the Four-Element-Seal, which is the basic of the Eight Tigrams Seal, a sealing jutsu developed by the Uzumaki. At the link, Minato told us which seal he'll use. So we know which seal it is.

To use the Power of the Kyuubi, Naruto needs to learn how to open and close the seal!!!
MINATO LEFT THE "KEY" TO THAT SEALING JUTSU TO THE TOADS.

Thus the Toads entrusted the key to Jiraya, a sage close to the toads, Naruto's Master. So the intention of Jiraya, after taking Naruto as his apprentice, was to teach "that jutus" to Naruto when the time is ripe, so he could fulfill his father's wishes.
How many times i have to proof it. Read the goddamn posts before. It's so ridiculous that we have PROOFS and LOGICAL FACTS that shouldn't be misinterpreted as it seems so obvious and simple. I could really freak out when people speculate about this and that jutsu although it is already clear. I proofed it with this post again! Yeah Naruto can learn this and that, however, the WHOLE FU**ING "THAT JUTSU"- thing was referred to the sealing jutsu on that scroll. What's AFTER "THAT JUTSU" is something else. People who don't get it= Pricks, so simple. Oh lord, please let it rain some brains!!!
For all people who STILL cannot see the truth and wants to believe to some shit, here is my advise: STOP_READING_THE_MANGA. If you are unable to understand such trivial things, if you are unable to READ the chapters and make conclusions with the facts that we've already known by former chapters, than please STOP IT READING. I'm just tired of you guys.
