My Test Results

[Doby]

My tests.....

Stock Prop...no changes to any factory settings......35 Mph and running wet...temps in the 90's...handles well

Raised strut......38.7 Mph....temps in the 90's...handles well

X642...sharpend and cut.....42.8 Mhp....lifts the bow out of the water nicely.....temps in the 115 range ...handels nicely.....moved the turn fins up half way and still handled great...

Grim L45X68 ......44.8 Mph......temps in the 130's and chine walked quite a bit

M445.....sharpend and cut...46.5Mph....temps in the 130's, handles well....riding on the last 2 inches of the hull or so.....

All results after about 2 minutes of run time (more or less)

Like the temps and speed combo of the X642...sweet running boat with that prop.....easily get 4 minutes run time with 30% left in my 30C Turnigy 5800 LiPos.

Epoxied some supports to the hull and motor mounts as I thought the hull flexed a bit to much..

Put a bit more epoxy around the stuffing tube/ transom area.....


Well done Mikey

nice tests what kind of run times are u getting with the 445 and 642...if i get one i would need it to run off shore at 4 min minamum.....

Wow nice results. Could you tell me is that with all the stock connectors, motor and esc. Just wondering if changing those would get temps down a bit, connectors that is.

Thanks,
Eric

Quote me...."Like the temps and speed combo of the X642...sweet running boat with that prop.....easily get 4 minutes run time with 30% left in my 30C Turnigy 5800 LiPos."

I didn't use the M445 any more than for 2 runs to verify speeds and temps...didn't like the temp I was seeing. In cooler weather it might work well.

Remember...fastest doesn't always=finishing....

Good to hear. I had just bolted on a 642 to run next time out.
Are you running strut neutral?
About to put a ul1 motor in it to see how much of change the extra kv makes.

Where were you running the batteries at in those runs?

Where were you running the batteries at in those runs?

All the way at the back of the trays, with a GPS in the front of the tray......

Strut was slightly angled upwards....not sure a UL-1 motor will be a good set up in this hull...there's a reason Mikey didn't go that way..

Nice info, how high did you raise the strut on the stcck 2nd run ?

[NissanGTR]

Maybe you could take a picture of the struts position for us?

As requested...height = 1/4"

Your the man! Thanks!

Thanks man!.. good test info!

What would you guys say the ideal temperature should be on the Motor/ESC?
