This is Uzair. I am trying to see if it is permitted to use lead based weights - coated in thick rubber or plastic - or is that against safety.
If it is allowed, what are the rules to allow its use?
If not, what are good alternatives that is simple to manufacture?
The choice for lead was to counteract a large abount of bouyancy - 25lbs without taking up as much room as other alternatives. The space for hull to accomadate electronics is the reason.
I noticed Blue Robotics sells lead based weights too so wonder If It could be used compared to bulkier alternatives.
Any information and suggestion is appreciated.
