Rudders
I have never seen a Habu in person but seen videso and coments.
The Habu weights less and can be hand launch and is more acrobatic. Don´t think is faster. Probably is more fun. Hobby King has the Stinger which is the copy cat of the foam Habu.
My het f18 is not acrobatic and probably if a you are a good basball pitcher will be able to hand launch. Also wheight more 2-3 pounds.
Think the Het f-18 will not be as fun as the Habu but will give you exprience in throtle managment since is required in jets since have no props, and also in landing fast since wing loading is higher than habu. For me the most enjoyable part is landing and flaring this het in high angle berfore landing.
The speed of My Het is aprox 70-80 MPH, if it is a bargain go for it if not there a better edf now days. I got mine real cheap and already had all the electronics and fan.
