Front end reinforced with 2 or 3 layers of cut-offs

Reposition server, to allow for dual rudder arms

I meant on the outside with Rubber Bumper.

With such a light boat and no great speed do you need double rudder linkages? I've only got one, built by someone else and it's fine.

Martin (Admin) · « **Reply #178 on:** August 08, 2023, 06:53:45 pm »

Yeah, my first one was OK too .... just thinking about over centering the single link ....

ChrisF · « **Reply #179 on:** August 08, 2023, 07:43:35 pm »

Can you adjust the amount of movement on your Tx? You don't want anywhere near 90 deg anyway.

Double servo linkages are nothing but a recipe for disaster. We don’t use them on 50+mph race boats with 30kg+ torque servos, so a club 500 definitely doesn’t need them

ChrisF · « **Reply #182 on:** August 08, 2023, 10:49:49 pm »

I'm trying to get my head round it but don't non-parallel linkages cause binding?

I'm using double linkages on my big heavy Swordsman, but parallel. Not essential if you use fairly short and strong rod but I think makes for a balanced system and shares out the forces, particularly on the servo. Doubt I shall wear it out though!

I agree .... but I'm a poor builder and terrible at geometry!

With non-parallel links, something is bending.... but I don't know what! - https://youtu.be/qcl8A0RbL8Q

With that rod Martin you definitely only need the one!

I hope those "slinkies" between the servo and rudder are only temporary!

Finally plucked up enough courage to glue the deck down today!

Martin (Admin) · « **Reply #189 on:** August 28, 2023, 07:42:59 am »

After all the fuss I made, the gluing .... it didn't go well .... as NASA would ( sort of ) say; 'Huston, we have a problem!'

The transom and a couple of others areas, didn't seem to bond ... they didn't even seem to be touching at all ???

Anyway, I was going to mastic fill / bond the gap anyway, so still working to plan .... ish!

My Club 500 kit remains firmly in its box!

I will build it in the winter when I am at home more and have finished my scratch Sea Commander build project, but I am enjoying your build, and I would hope to finish mine a bit faster

Martin (Admin) · « **Reply #191 on:** November 04, 2023, 03:23:50 pm »

Ok, so a couple of weeks ...! since an update .... where did I leave off?

... oh yes, wet washing the motor - https://www.youtube.com/watch?v=WfNjF5_PFsQ

Let me edit up some progress from then.....

J.beazley · « **Reply #192 on:** November 04, 2023, 03:39:49 pm »

Out of interest did you test the current draw on the motor before and after washing?

Jay

Martin (Admin) · « **Reply #193 on:** November 04, 2023, 05:05:24 pm »

Danm it, NO.... should have shouldn't I

.... it did sound a LOT smoother and Quieter after wards... can that be measured?!

Circlip · « **Reply #194 on:** November 05, 2023, 10:38:01 am »

Even if you don't do a 'double' linkage (although easier on the servo bearings) rod should be parallel to servo and rudder post centre lines. Correction for reduced rudder throw can be done electronically.

Regards Ian.

Hi Martin,
I've just watched the motor washing video (thought it was a wind up) it's unbelievable how much muck came out of the motor. Does doing this damage the motor long term though? Re adhesive have you tried Stixall Stan from Kirklees put me on to it and I have to say I've found it brilliant and you can paint over it unlike Silicone. Good luck with the rest of the build.
Cheers, Pete.

Hi Martin,
I've just watched the motor washing video (thought it was a wind up) it's unbelievable how much muck came out of the motor. ....................

It isn't really "muck". When the motor is assembled the (often square) brushes are not a good fit on the (always round) commutator. The "washing" process wears the bushes so that they are a good fit. The "muck" is thus mainly the carbon that has been taken from the brushes. The theory is that after this the motor will run better with better contact and less arcing between the brushes & the commutator. This might actually improve the life of the motor but then again it might not.

Back in the day when we did this we used a very low battery voltage and thus low revs.

More glue testing.....

"Wet washing" / water wash bedding in was a big thing for the RC car boys back in the day .... always wanted to try it!

zooma · « **Reply #199 on:** November 30, 2023, 08:59:37 am »

Hi Martin,

Can you summarise what adhesives you eventually used for each task and rate your success with them please?

I doubt anyone else has tested as many options as you have so you have saved me a lot of time and worry .

.........my Club 500 winter build will be starting soon............

Bob.
