    My Gato RCABS style

    My crazy friend Wayne Frey sent me this awhile back and he had started it but not finished. He had joined the hull and added the drains and a few other details but the rest was mine to do.

    I never liked the hull cut so I instead just slipped the WTC in through the open deck. Slipped in like a charm. Saved a lot of work and that cut.

    Next I converted the Cylinder from gas to RCABS. It was very easy to do.

    I also used the included kit props. They worked great!

    This boat runs on 4 ch. The bow plans can be manually folded down and their position set or changed. I use an APC and she dives very level and smooth without functional bow planes.

    In the video you will see decks awash. When I trimmed her at home she sat a great deal higher. Not the true scale water line. as you can do with the additional low pressure pump, but close enough. I wanted to keep this little boat simple as possible. But when I got to the lake I couldn't get her to less than decks awash and I couldn't dive. Something had changed and as it later turned out there was residual air in the bladder I didn't remove before running. Rather than notice that, I added wait. When I got home I re trimmed her in the pool and the shot of her in the pool is the actual running water line I have now with RCABS alone. Not bad! All I did was make sure that bladder was dead flat.

    This has got to be smoothest running small boat I have. Easy to set up to. Remove the one AFT screw, slide the deck off, drop in the WTC and go. One brass brace holds the WTC in postion. You can see it going accross the ballast section in the picture. Two screws hold it there. Other than that you hook up the two dog bone couplers and the two shafts to the rudder and dive planes.

    I use a 2100 2S li-poly battery that loads in the front section while still in the boat. It lasts over an hour. I have an on-off switch that a 1/8th shaft through a seal in the aft end cap activates. I don't even have to remove the deck entirely to turn it off and on. Just remove the one screw aft and lift up a bit and I can access the switch.

    Here's a little video my friend Reid shot. The Vosper is mine too. We had a nice day. Oh and not one drop leaked in anywhere.

    Is that a Big Dave

    Is that a Big Dave cylinder Steve? I will be going RCABS with mine. Thought about gas for a while, but looks like you're getting plenty of lift. Besides, my PARCHE RCABS cylinder has been practically bulletproof. Why mess with success??

    Can we get some tube & bladder dimensions?

      No Chris that was a

      No Chris that was a D&E Wayne sent me with it. He suggested I convert it to RCABS because he was going to do it.

      It turned out to be a simply enough mod. Works great. I don't have a single gas boat anymore.

      Even the big 1/32 VIIC is RCABS-R with a low pressure pump for surface trim.

        Funny... That's what I have.

        Funny... That's what I have. An old D&E WTC 3 Mod 2. What size bladder did you use? Di you add on to the cylinder at all?

          I used BD's large bladder.

          I used BD's large bladder. I forget the size. But it nearly filled the section. This was the Gato D&E WTC intended for the boat not what you have.

          I didn't change a thing except some of the seals and added the bladder system. Dead easy.

              It's 2.5 as I recall

              It's 2.5 as I recall Chris and at that it just slips in without that cut to the hull.

                I'll post a video I did of the mod in operation to help others here that might want to do this. If you think that will be of help?

                      Sure thing Chris. The pump

                      Sure thing Chris. The pump is in the front compartment with the servo, micro switch, and valve. It leaves plenty of room for the li-poly 2100 2S pack.

                      To get the bladder in I just cut a section I can remove in the ballast section. Hockey tape holds it in place and I have yet to replace the tape in many runs.

                            Re: Pipe Size?????????????????????????????????????????????? ?

                            Every experienced builder gives the nominal wtc pipe size but never gives the OD and ID.
                            Generally it's about 3mm or 1/8". You can go smaller when diameter goes below about 2" or 50mm, but make sure you know what your doing.

                            This applies for extruded plastic tubing. GRP laminates metal etc. can go a lot thinner as they're generally more rigid.

                            My highly scientific method of dealing with this, is to sit my backside on the tubing. If it can take that without squishing up, it's good to go.

                              It doesn't bother me at all. I just send a PM to the SOB and ask for those numbers should I need them for my own project.
