hull suggestions

[MBattig]

I've got a 12 turn trinity speed gems motor, and a couple of 6 cell battery packs. I was wondering if anyone knows what hull would go good with this type of setup. I'm leaning towards a monohull like the 22" El Lobo.

 

[Andrewg]

Any 20-22" hull will work fine with that motor (just the right turns for 6 cell mono) - however it will wear fairly quickly

To reduce wear and maximise speed use 9% silver brushes and purple springs and water cool at least the brushes. Use a small prop like an X430-x432

I just bought a 22" BBY oval master. I was wondering what the best way to water cool my motor would be. I didn't know you could cool the brushes on a motor.

I also dont have access to any octura props via my local hobby shop, Do you know a good place to order them from?

Thanks

congrats on the new BBY OM 22. that is a nice hull. attached is a pic of my motor cooling (can only) on a microbullet that I used to have. very simple.

offshoreelectrics.com offers octura props with a very reasonable shipping fee. I am sure there are others.

We can ship props with $1 shipping as long as you understand theres no insurance involved. We will also have stock, unmodified octuras with in the next day or so.

I guess I would want to buy an Octura x 430 or x 432. Do you keep props that small in stock? I ask because I didnt see them on the list. If so I might be interested in buying one.

Steven...do you also carry Octuras in carbon fiber?

 

[Pagemaster]

I carry the Graupner Carbon fiber which are a very close replica of the x series metal.

Sorry I dont carry the small x Octuras because they are 1/8 shaft. Not much call for them. I could order them from Octura if you cant find them else where.

I'm not sure what type of prop I want yet, but the $2 X431 looks pretty good for the price. ;D I was also looking at the articles on the offshore electric website, and I was wondering was size tubing was used for the cooling coil? Is it the same as the tubing used on the brush coolers?

Thanks

And I forgot to ask (this may seem like a stupid question but) which type of cooling is the most important. Brush cooling or just the cooling coil. I'm asking because I'm not quite sure how I would mount brush coolers on my motor.

[Andrewg]

brush cooling is the most important - the mnotor can might seem hot but the mags can go to 300 without damage

brushes run hotter still and easily suffer damage run the water tot he brushes first ( red->black ) then around the can

Matt...check these out

[MBattig]

Wow! Where did you get those? I'm almost afraid to ask for a price.

Solder 1/16” X ¼” X ½” brass tabs with 1/8” OD brass tubes through them to the sides of the brush hoods opposite the springs...

save the $40 and thank the man....

 

[MBattig]

I think Garry's route is the one I will take. As for the cooling coil, is it absolutely neccessary, if you are already cooling your brushes?

 

[Propjockey]

I think I'll take that route as well!

Thanks Richard! (and Garry)

 

[MBattig]

ya, Thanks!

I have to admit... I have learned allot from Gary. I don't know him personally but I bought a set of his 1/16 scale Atlas plans and he has been a tremendous help. I graduated to a .15 Miss Bud, and I now I am the proud recipient of a set of J.D. 28/30 W.O.F. plans. I still have a lot to learn but that guy is the one that got me hooked!!!!!

 

[Andrewg]

cooling the can isnt absolutley necessary unless you have neo mags which can get damaged

you will get a several percent power loss from hot ferrite magnets but the brushes are critical - they are the part whiich over heats, burns the comm and can chip and damge it due to effects of heating - so keep them cool and more han half the battle is won

the mags have to go to 300 degrees befopre they get hurt
