i finally got the videos of the challanger on the comp. check them out, their short but you get a apreciation for the speed.

setup is

14xl
20 ib 4200s
hydra 120
speedmaster hardware

the rudder is bent is why it's so unstable i think

skidooguymxz550

yeah, i know, no matter what i do to cog or trim she still runs loose. it is a blast to drive. it's only flipped twice and once was a blowover

A lot better than that Novak motor you had in there. Looks very unstable though

Maybe you should put wings and ailerons on it... looks like it could use them since your literly flying above the water!

Looks good. nice and good speed.. I think you have a problem that can be corrected with trim tabs.
your rudder would be causing some stability issues but not that much.
throw on a set of tabs and it should help.
also lets see the boat do a fast turn. I am interested to see if it "hops" in the turn.

Ok so if it hops how would you correct it?

skidooguymxz550

yes it does, sometimes it skips through the turn like when you don't trim down in full scale

CadillacDTS2001

that would be a large prop lifting the turn out of the water.
I think a 14XL is a little slow for the boat thus meaning you need a large prop. If you went with a 12 or 11 turn and a smaller prop i would not be surprised to see alot more speed and alot more stability

hmmm.... i'm running a k45 on her rite now. i've tried a 47 and i couldnt get her wide open

Can you post a close up picture of the boat. Possibly side profile and the transom.
