Hey guys
Tried two 7.2v 4500 nimh packs in my new aquacraft UL-1 superior while I'm waiting for the lipos to come (yes the cells should be able to take the amp draw) but the front kept diving into the water as soon as I pulled the throttle.

I tried different throttle levels but it kept doing a nose dive into the water.

I lowered the turn fin a little bit and I raised the angle of the strut upward but the front kept going downward.
I even put one of the packs to the back of the boat to make the back heavier but it still had the same problem.

Each nimh pack pack is nearly one pound and the lipos that are coming soon are turnigy 2S 5000mah 20C, each is 284 grams (10 ounces).
(There's a flightpower pack that was suggested in the manual that's 268 grams (9.45 ounces))
So with the turnigy lipos it would be 12 ounces lighter.

The packs are placed in the very front next to the sponsons:

Any other things I might try besides different battery weights and hardware adjusting?
Maybe even shift both the nimhs to the back of the boat?
