Started this kit months ago. Went out to visit son in LA for a month. On return got going again on it. Did hull joining and cut out other parts. Drilled holes in hull. Months went by and built WTC and ballast tank. Found on line a builder who used 3D parts to replace poorly designed Krick dive planes n rear end drive parts. So now I’m up to fitting motors in place and control rods into WTC. I found my idea to turn water pump on and reverse won’t work. I purchased on line a gizmo made got it. Also my dive plane servo was bad so waiting on replacement. It wasn’t an easy build. I did several Dumas subs and the big Revel sub. All easier to do. Krick sub has you unscrewing a lot of nuts to get to battery. I am adding what Dumas did a soda bottle screw cap section so I can recharge and Dubro push pull switch. The center section tank bulge can hide them. Pic is the WTC not installed in hull and top center section. So far. Been working while watching tv. I hope to finish this month? Still need painting finished. I also need to fabricate two life jackets for conning tower. Anyone else build this sub? Nice details but a lot of work.
