Hello here I will post all of the modifications I have made to this great sub.It is by far the best platform to make majormodifications to improve its already in general good design.
It is built very robustly to be reliable without being cumbersome or over engeneered,simple yet complex todo some prety complex things like a perfect hover,that alone is dificult for most mass produced subs,the quality isalso very good,parts no problem ,Ilike them so much that I will use many of them in future subs like the main control board it can be used in any pump type sub and iether a Futabaor JR radio of 4 channelsto 12 can be used perfectly,
YA thats great the board has several great features ,bult in failsafes are signal loss,low battery voltage and water detction all make the sub surface untill corrected or reset with power switch.You dont need the power board but it can be used as well.
Well I can say that I have modified this thing to the max over the past few years and have loved doing them and useing them as well,I use this sub mostly on the clear rivers in Florida and often take her very deep into cave springs hence the "inhancements",out of the box it just would not do,I want or need long run times,it takes 2 hours by boat just to get to some of my favorite places to run so she must run long, an hour or more hence the larger battery then now the 2ea 5700mah Lipos they should give plenty of run time !
Larger single kurtknozle /rudder was added ,largger forward dive plains,planetary gear drive,improved bushing stuffing box not a ring seal type.
See list below.
1 Larger forward Dive plains
2 Larger battery
3 Planetary 6.5 to 1 gearbox
4 Water cooled motor
5 Trimed down aft plains
6 Larger prop and Kurtknozle /rudder
7 25 or so LEDs for knight use and cave runs
8 remote on off of the above LEDs
9 Remte controlled on demand variable bow thrusters made with Lego technics
10 Easy acsses port for ventilation or fuse replacement
11 Added a inline waterfilter or fuel filter so that the pump is protected
New add mods
11 2 each Lipo 5700 amp h with ballance extention cable to vent port for easy charging
13 Added 2 kurt knozles with 2 brass simitar counter rotating props on one ESC with 2 ea. 3.5 to 1 gear boxes and 2 u joints and 2 high speed can motors.
14 Stern servos moved to underneath motors ,no rudder rod on top of the stern as before.
15 brass tube bushings for prop shafts
16 2 rudders directly aft of props on the kurt knozles
17 Aft dive plains redone for dual props
18 90 degree Tilting color fish eye camara
19 mechanism for tilting the camara
20 Verticle stabalizer enlarged and keel fin also enlarged
21 Pinted to suit multy color special Automotive durable paint with clear coat
22 Added antenas for looks...
23 Removed charging jacks not needed for Lipos but space for above mods
24 Military cannon plug for watertight electrical connections of LEds and video unit that run in the wet
25 Added 10 channel JR reciever for enhancements and extentions with labeled ends of reciever channels for future video overlay system.
26 One way ventilation or overpressure valve so that compressed air will not harm saels or cassing very important.
27 Dual brass and oillite bushings stuffing boxes with grease ensures 0 leakage.
28 Removed and then replaced the camara off on switch and used it in the construction of the tilting camarras mechanism,a stainlesteel bolt was put in place of the switch seal unit.
29 The aft diveplains seal on top of the aft area is free to rotate and will later be used for a rottating radar??stil to be seen.
30 Voltage and temp indicator on side visable when sub is turned on
31 Voltag can be read from outside without turning on the sub at all times and is off when sub is on so that electolissis does not build up.
Well thats about it so far the viids will show how she operates without the cassing as I have not re ballanced the sub yet which is a snap with this sub.
I will explain more on how each of these where made in the future but if you have any questions just post or PM me Thanks
