Let's take a look at a Hobao Hyper 21 3 port bump start turbo plug .21 nitro engine

[@joshlaquerre3197]

I like the colors of it after the discoloration

[@islandrc-duke1972]

cool engine and overview of it,you got some cool nitro engines,awesome stuff

[@jakeandrules7724]

Port the sleeve and add grooves for the side transfer ports. Did you try removing the carb restricter and tune it from there? Where are you lacking power? What % of nitro you using?

[@TastyBRC]

Those ports are huge!

[@NitroTalkwithTodd]

That intake may be the widest I've seen..

[@DC2Megaboost]

Great vid 💙 the channel 👍🏽

[@Sponge4664]

I have the 8 port non pull start version of this engine just broke it in

[@ryansilliker4328]

WOuld the 21 cooing head fit on the 30 block ? asking for a friend lol

[@bobbygill5117]

I have a hyper 21 3-port with turbo fan, and a hyper 21 8port with turbo fan. I just ordered the 21t head button, which engine would it be better suited for?

[@danielwood4590]

Hi Todd how do you rate the old .21 8 port I've got chance to get one and wondered if they still hold up today against some more modern engines
Thanks and keep up the great work

[@NitroTalkwithTodd]

The hyper 8 port was one of the first engines I owned, I learned to tune on that thing. Very solid engines that are known for carb issues. But with some fresh o-rings, the carb is great. I think it works better as a pull start basher than a bump start racer, but is certainly capable.

[@samsonight2721]

Is that the same carb they run on the .30 maybe then run the same carb on all there engines they look similar that's for sure

[@NitroTalkwithTodd]

It is, all the modern Hobaos run that carb
