Kintoun

[Kid Trunks]

So why does Goku use Kintoun when he gets wished back to fight Nappa and Vegeta? Is Kintoun still faster than Goku? It seems a little unlikely, because Piccolo keeps up with it before their fight with Raditz. (It may not have been going at its maximum speed though) Remember that Goku was fast enough to cross snake way in two days and he still used the stupid cloud afterwards. It could have been to conserve energy, but if that was the case why not save the senzu bean til he flies there?
When do the Z fighters really get faster than Kintoun? (It disappears after the Saiyan Saga until Gohan becomes Saiyaman, at which time Gohan easily outflies it even in his base form)

I take offense to that.

Why? Are you still using the stupid cloud as well?

Nam did it.

Only in the anime, though.

Was Roshi ever able to ride it? If not then it seems weird that he would have control over it at the beginning of the series, plus he seemed pretty confident that he could ride it as if he had done it before. He must have got it when he climbed Karin's tower.

Yeah, when Goku is picking out a new Kintoun from Karin's gigantic one, Karin says that Goku's old Kintoun was originally the one he gave to Kame-sennin back when Kame-sennin trained under Karin way back when (Kame-sennin himself says to Bulma and Chi Chi that he got Kintoun from "Kami-sama", which I guess is who he thought Karin was). Presumably he was able to ride it then, since like you said he thinks he can when showing Kintoun off to Bulma and Goku.
