I recently broke my stock balsa servo mount of my boat, and i need to replace it now. Here is what the stock servo mount looked like:
http://cgi.ebay.com/25-deep-vee-ARTR-with-motor-and-ESC-racing-spec-white_W0QQitemZ290327250603QQcmdZViewItemQQptZRadi o_Control_Vehicles?hash=item4398da46ab&_trksid=p4634.c0.m14.l1262&_trkparms=%7C293%3A1%7C294%3A30


So i tore the old one out, and grinded all of the epoxy off. I am going to lay some FG mat before if epoxy the new servo mount in. But i need recomendations for good mounts. Preferably from here:

I was thinking this one?:

Oh and i am using a standard traxxas waterproof servo.

saint paper the servo's bottom and epoxy it down to the hull, its more clean, more safe and save money :rockon2:

being a bit of a cheap skate this is what i do, buy a lenght of alloy angle (see pic) its 32x20x1.4 mm or around 1.26x0.8x0.055"
cut a piece the same width as the brackets on the servo
then on the 20mm section cut a piece out so the servo sits in
you then have 2 pieces siting up just drill 4 holes and its done
its about $4-$5 for a lenght and you get about 30 servo mounts from it

I could make one out of angle iron, but i do not know how it would do with the angle of the hull. Plus i would like to use somthing that has tapped holes, so i dont have to use a nut. :smile:

you dont have to worry about hull angle, the servo can be set slope down with the hull, but like i said, epoxy it down

Ok, thanks :banana:

Im going to make one out of angle iron though, because i would like to be able to remove the servo. :thumbup1:

I use these in all my boats http://www.offshoreelectrics.com/proddetail.php?prod=dh-jrpa244 I cut a piece of 1/8 light ply. Mark the mounting holes. Drill and use m3 T nuts through the ply, cut the hex head bolts to length, epoxy the ply down with a bit of tape covering the T nut holes. Then just bolt her down. Easy to remove , looks professional ans makes removale of said servo easy!

I use the aluminum angle bracket ozz mentioned, I wouldn't epoxy it though, if it fails you may damage the hull removing it. If you go with glue - use sillycone it holds and the servo is still removable when (not if) it fails.

Jesse what do you mean by dont use epoxy? Are you talking about just epoxying the servo down, cause i am not going to do this. But i am going to make an angle iron bracket, and i was going to fiberglass it into the hull with some fiberglass cloth and resin. :huh:

07-13-2009, 09:18 PM
Well i made a nice aluminum bracket, and i need to attach it to the hull. What is the best way to do this? I have some epoxy that i could use, or i can fiberglass it into the hull. Which would be better?

Maybe some double sided tape?

i usally drill a few holes in the base part off the bracket, then epoxy it down.
i usally do mine at the start of a build so c/f then goes over the bracket when doing the rest of the inside. but you could just run a piece of cloth over it and glass it down

M.M.

I did drill some holes in the bracket. So i think i will glass it in, because i dont want the expoxy to fail like it did with the previous mount. So are there any secrets to glassing the mount in? I have some fiberglass cloth and polyester resin. :popcorn2:

not really just stick the mount down,i use 5min epoxy,let it dry mix up some resin brush some over the area you want to cover with the cloth,lay the cloth down and put a bit more resin on top with the brush,just make sure the resin soaks threw but dont flood it you wont need much

Doesn't hold up. Been there, done that. Steven's plastic mount looks GREAT to me! epoxy a piece of plywood to the hull and screw the mount to that.

Cool! Put it on your front page in the "NEW" section! I'll be watching for it!

Steven's plastic mount; clean area thoroughly; " Shoe Goo" will hold it semi-permanently-won't ever break loose from servo torque, but can be twisted off with a strong wrist if need be. Looking forward to the new mount, BTW.

Thanks ozzie:thumbup1:

One last question, you have the 25" df copy correct? How strong is that hull? Should i lay a peice of fiberglass mat down in the hull before epoxy/glass the mount in there?

the hull it self is rather strong,only problem i have had is the hatch cracking
but it was from a big crash.if yours has the wood motor mount add some extra epoxy to it

M.M.

Well it had the old wood mount in it but i cracked so i made the new alluminum one for it. The only reason why i was thinking about renforcing the spot where the servo mounts to the hull was because when i was grinding out the old epoxy i may have gone a little deep and into the fiberglass bottom of the hull.

I have been using the 3M double sided tape without any problems. You first have to clean the surface with alcohol and then put the tape on.

Sorry to hijack here, but I just recently got a hull with the servo epoxied down to the fiberglass hull. How in the world do I remove it?

Well my mount is all glassed in:thumbup1:

Now to mount up the servo and attach the linkage tomorrow.

Please post pics MM!

I have a Hitec HS77B low profile servo that needs to be mounted upright. Any suggestions from you guys?

Scuff the bottom and mount it directly to the hull.

Or, buy a set of servo mounts from a r/c truck or car and use them.
I used a set from a Traxxas T-maxx that were for the throttle/brake servo.
Trimmed a bit off the end of the legs on the mounts, turned out perfectly.

this is what i did for a stand up servo, steve sells a stand up bracket maybe you could trim it down,excuse the dirty pic boats been collecting dust for awhile :biggrin:

Steven, if these are the bolt-together mounts [ like Jimmy Sterling used on his PT build] I want some ! When ?
