[100 mph jet boat]

Hi guy's... I just ordered me a impulse 31 should be here next week.
But in the mean time i would like to order some of the needed upgrades.
so far from all my reading i should upgrade.

5.5mm bullets
flex cable
collet / coupler
trim tabs adj.
prop x645, 42x55 grim racer, 45x55

can anyone help me out with links or part #

and is there anything else that i need to do????

I would just upgrade the bullets and prop, I never had a problem with anything else.

That sound good to me
What prop you running?

the 42x55 may work but the others are way to much prop for stock setup. That or bring a fire extinguisher.

Another easy upgrade is the run 4s2p (two 4s parallel). Double the run time and lowers amp pull considerably. Plus the impulse has plenty of room to fit high mah 4s batts in it.

Try the sky lipos. I've had great luck with them. Better than the gens in my opinion.
