    a bunch of questions

    hey guys i'm really new to this whole boat thing so if it seems like i'm asking alot of questions it's because i am lol....in stead of making a bunch of threads i figured i'd just make one and put a bunch of questions in it..

    first i'll give you some info.....the boat is a 27inch abs hull cat....it currently has two props comeing out the boat(i plan to put one out the back)....and thats about it lol....

    so here are my questions:

    1. Electronics....i'm thinking i'm going to put a single feigao 540xl or 580 and a castle creations 120amp esc...is there anyting else recomended??..

    2. With the set up i have above would to 3s lipo's hooked together to double the mah be good for this set up??...and what is the max # of mah i could run?

    3. I plan on taking the dual props outa the bottom and running one out the back...is this a good set up to do that with on a cat??: http://www.offshoreelectrics.com/pro...od=ros-monosys?..

    4. What would be a good prop to run on this boat??

    that is all i can think of for now....i'm sure there will be more coming...sorry for asking so many questions like i said i'm new to boats and don't know to much about them....please help me out and answer quick so i can start the build as soon as the boat gets here...

    thanks in advance -Austin

      the rudder/strut you are looking at is for a mono and wont work on your cat. to make things easier you could run somthing like this http://www.offshoreelectrics.com/pro...502b15&cat=123 what sort of hull is it you maybe better off starting with a fresh fibreglass hull if your going to spend that much on motor/esc and hardeware. somthing like this http://www.offshoreelectrics.com/pro...p?prod=Aero-MM

          ok with that strut would i still have to have the tube come out the bottom of the boat??...and it's just an abs hull....i'm just going to build it with good electronics then upgrade the hull later...i want to get a boat going soon and if i buy a different hull now i wont have it running any time soon....i will upgrade to a better hull after though..

          i would get a pic of the hull but i can't find the thread they were in..i think there are a couple in my "rudder help" thread

                      im thinking the fiegao 580 to be too big for that hull, pics of the hull and more specs on your lipos will help people help you

                              Who makes that?
                              It reminds me of pro boat with the rudders from a sundancer & the motor trays from a mini-v

                                      LST XXL,
                                      I'm not knocking the hull, Honestly I like it. I'd like to know what it is, so I can be on the lookout for one myself. Maybe someone here can identify it for us.

                                              It looks like an MRP fast cat. an SV27 motor and ESC should power that nicely.

                                                  I'd use the Ammo 36-50-2300 motor and SV ESC

                                                      it kinda does look like that but at the same time it doesn't lol....


                                                      and do you have some links for the electronics you guys suggested......and apprximently what speed would i expect to get with it?
                                                      if it ain't broke you ain't trying hard enough.

                                                          before brushless powering that, I would be inclinded to scuff the inside of the hull and lay a floor of carbon or fibreglass to reinforce things so it doesnt blow apart and to reduce flex

                                                          Also you will want to cut the skegs off the bottom that the old stuffing tubes ran through.

                                                          Ammo sounds like a good choice
