New build-Club 500 class

[F1 madness]

Well with the weather putting me on hold iv started another build.
The boat club iv joined locally to me were on about having their own 500 series class,and asked me if i would like to design somthing for them.
We spoke some more and could nt decide on what style of hull they wanted and left it upto me,so what i decided was if i was to design and build 3 types of hull then we could put it to the vote.
They wanted somthing a little more modern than the brushed series cab cruiser style that nearly all the other clubs run.
The 3 types of hull im working on is a cat,F1 and a mono but these would be designed to run all the same motor,esc,prop,and hardware (strut and rudder assembly) etc.
Iv got do it as cheap as possible for it to be cost effective for the members.
This is what iv got so far:
Hor hardware.
31mm prop
80amp rc max esc
2845,3600 kv,watercooled inrunner motor but also looking at a 450 Heli 2415-07T Brushless Motor 3850kv
2s 3000mah 35c Lipo
iv also got HOR water cooled mount if we decide to go outrunner motor as well as just a normal mount.
Still got to decide whether to use a standard servo or mini servo either which will be metal geared.
Heres the pics of the 1st im building.
Hardware:

iv mounted the hardware and the 1st impresions arent good to good,i brought this as a complete kit complete with the 31mm bronze prop,the rudder only passes the the prop tip by 15mm,the prop is close to the lower rudder support so any adjustment any +angle or strut height adjustment wont be possible.
I still cant decide which motor to run,but thinking the watercooled inrunner will be the best 1.
Heres some pics:




Gonna make a mount to hold the servo in the sponson

[F1 madness]

Put a small piece of brass tube epoxied in,this will be finished of and will be moulded with the rest of the hull,leaving only a small hole to be drilled to pass the stuffing tube through then on the mold just fill around the stuffing with epoxy and that will seal and hold it place,rather than cutting a slot and maybe messing up the gel coat,just thought it would make it a little easier on the builder.
The tube used is the id as the od on the stuffing tube.



I used the watercooled mount and the inrunner to line up and get it where it clears the hatch,but ths way either inrunner or outrunner can be used with out having any issues or moving the mount etc.

Got the servo mount made and installed(ill be using the hor alloy 1 in the fibreglass versions) hole drilled in transom for the brass tube to put the bellow on to,bent z for fixing to the servo horn.

sorted out the cooling inlet (through the hull) and the outlet,gonna use the pick thats on the bottom of the strut,if its no good ill do another.


Iv used some alloy tube for the outlet and sanded it flush.

Nice job. I have some of the identical hardware and also noted just how close the prop came to the rudder support shaft. I may try to design some unique wire-drive boat with an outrunner but it is still on the drawing board. Trying to think some something real unique like the mating of a rigger and a cannard. Will pass it by my airplane design guys first to get their input. I'll be following your progress.

[F1 madness]

cheers bud,im gonna try and get a 30mm,1,4 prop to gain a little extra clearance if not have to look at changing the hardware.
Good luck with what ever you decide to build,look forward to the thread

As always excilent work Daz,,,, I dont understand what does the 500 mean???? is that like a size spec.. PS i love how you do the pushrod threw the hull with the brass tube and then the rubber boot over it,,,very slick!!!! I have to remember that one...

Thanks jerry,the 500 stands for 500mm long.
I find it easier this way with the pushrod through the tube,the just cable tie the boot and seams to work for me this way.

Well after a couple of crap days iv finnally manage to get this all put together,all thats left now is to final sand it,glass cloth a little filling and paint.
Where everything is at the mo CG is around 35% from transom,and overall weight is 2lbs 1 ounce.







I am thinking of changing motor to either the outrunner i already got or purchasing the same motor but 4000kv,and also gonna order a 30mm,1.4 prop
:D:D
Was thinking of calling it GLS 500 (Goes like stink 500) LOL,think i might run it 1st though mmmmmmmm
