win some you lose some

i rechecked the numbers and am embarrased to say i should have seen this coming. i ran the numbers for all boats except the one i ended up getting. in my analysis of which boat to get, i off handedly said, "why would i get the semi kit, i'll skip that one". then, when i actually went and got a hull, i got the one i didn't run the numbers for. really, it shouldn't have matter because i should have run the numbers twice more after i bought the boat and before i installed the components. well, anyways, i didn't, and that was a mistake. check it out. the tank holds 1700 ml (.5 gallon) of water, or almost 4 pounds. the boat can support a total of 12 lbs. the hull is maybe 2 or 3 pounds, motors and batteries maybe 4 or 5, with maybe a pound or two of extra stuff, that adds up to too heavy.

the brilliant fix for the weight problem is to flip the level switch so that the tank stays almost empty instead of almost full. the trigger will go about an half an inch from the bottom. thats maybe 1/5 full. so something like 350 ml or 1 ish lb.

however, looking at the tank,

theres a bridge sort of thing in the middle and the issue is going to be the water comes in from the back and will fill the back end and no the front end. when the water level goes above the bridge its going to start filling the front section. this means instead of having a shallow water level its going to actually be about half full. which means maybe two pounds. the solution to this is the fill the back area with lighter non-water stuff. should be pretty easy to do... o wait, how am i gonna manuaver with no access point . its going to be building a ship in a bottle. so thats gonna be hard.

to make things worse, the relay lead broke. so i gotta go take all the soldering off that guy and get a new one. it turns out the sinking did more damage than i thought.

more sorta good news, i found a problem with the esc and i fixed it. its not worth getting into. problem, and got fixed.
kinda got start over in a sense tomorrow. but i'll push through
