After pleading and begging with Konohamaru for over months, he asked why such a request. Shingi would go to explain his reasoning. Still Konohamaru didn't buy it, and went to explain to Shingi that the Rasengan took complete chakra control. After sharing the details with Shingi he could, Shingi never gave up, something which Konohamaru admired...Shingi's determination. Konohamaru decided Shingi would be worth the while and began teaching him the technique. Despite Shingi's large chakra reserves he failed a couple of times at stabilizing the technique. It wasn't until a month later Shingi was finally able to utilize the Rasengan on his own and fluently.

Usage with Nature's I know would take a while. Which is why Shingi would practice none stop, at combining it with his nature. After years of mastering the Rasengan would Shingi be able to use it in combination of Nature's.
