Newbie needs help with motor and ESC

Hi,

I need some help choosing a motor and ESC for a second hand boat I brought for my son for Christmas:rendeer:.

The boat is 40" long & 11" beam single screw.

The boat came with a 540 motor which I believe is a little small? I plan to use 12v 7ah sealed batteries.

I need some advice on a suitable motor and ESC either brushed or brushless?

Anthony

Welcome aboard, I'm new to the model boat world, there are so many choices out there.

Any chance you could tell what the boat is, perhaps a photy or two might help

Welcome.

Depending on the type of boat and the speed you want from it, the 540 may not be too small. It also depends a little on what version of the 540 the motor is.

As troutrunner says, a photo would help.

Sorry I can not work out how to add a picture to this page, I have added the boat picture as my profile picture.

Hi Barrie,

Thanks for the information,

Is there anyway to add a picture to a existing post?

Anthony

Not that I know of, although You could always quote your previous message and add the photo.

Barrie

Should be able to add photo's using the edit button at the top right of your posts.

I think the Edit facility only exists for a short time after making the post.

Barrie

Ok barrie perhaps because I'm a moderator I can edit anything anytime.

That must be true Damien - the Edit button has gone from my post above.

Barrie

The edit buttons for normal users, is only there for a short period of time, normally up to 12 hours after that it vanishes off the posts to keep them from being tampered with in any form. (accept the moderators, we love to tamper with evidence )

If your having issues with uploading photos please take a look at the adding photo guide linked here....

Assuming you're still awaiting a reply, is that a picture of the model as your avatar? If so then I would suggest an MFA 850 with a 45mm or 50mm diameter prop if you intend to use a SLA battery. Personally I wouldn't use a heavy lead-acid battery in such a boat anyway; much of its power would be spent just pushing its own weight. For a very good, reasonably-priced ESC which will cope with this motor go for a Microgyros FR40. Brushless motors require far more current than can be supplied by SLA batteries so you'd need to use either NiMH or LiPo cells. The Vintage Model Company sell two sizes of brushless motor and matched speed controller; the larger one would probably suit your model.
