RE: Engel TAE or TMAX???
I built the U177 last year and just took iy out of the water Sunday. It is a challanging but fun build. I used the TAE set-up with the F14 radio, 2 magnetic on/off switches, a pressure switch,their self leveling switch. The only thing I will suggest is that you read the instructions and e-mail them with questions. The biggest challange is to make sure you can place all the items into the sub before you glass the water tight compartment in place. It took me many attemps as once you glass the compartment in place you won't have the access. Once you are done it is a ton of fun. I have about 100 hrs and no problems. The only thing I added is a 3 ft 1/16 steel wire so when I dive in the lake I know where it is.
