I like having the redundancy in case of a problem. It was proven helpful when one of mine burned out at the a club sail and I was able to run Dauntless back on one. I am in the process of replacing them with Astro 208D s.

Bill


Bill,

Consider visiting this thread before you do go with the Astro 208D's

Status: offline 		Thanks, but i already bought them and I have them in the boat. I was running 2 Electronize fr30xh which were supposed to be good and had problems twice with the last being completely dead so i gave up on them. I also put a 208D in my racing lobster boat and so far it has performed really well. All the newer esc have thermal shut down which I have experianced in the past. once they cool a little they work again. The best cure is to find why they are overheating which is usually the motor drawing to much current or ambient temperture from a overheating motor.

Does any company out here in the USA sell a Brushed ESC that can withstand 50-AMP continuous and without reaching thermal shutdown?

The PRO BOAT 50-AMP ESC that I have in my large 6-Foot Plywood PT311 did gave me a shut down momentarily on the 2nd Run this past Saturday for the Still High Resolution Picture session and the motor just quit. I am amazed since I have the Forced Water Cooling System with Water Cold Plate system and when the Motor finally restarted (less than one minute) I commanded the model to shore only to find the ESC just luke warm???

I am willing to spend some additional $$$ for a very robust ESC such that I do not find myself with an unresponsive Motor and heading to the rocks!

Appreciate any leads.

Thanks!
Carlos

Hi Carlos,

I know exactly what was happening to his ESC's. I knew the guy from back in the day...He was running one ESC for both motors and he like many guys back then was running huge props direct drive on his boat. When his boat was at speed you could barely see the wake because he ran big props and it was a big load on one ESC. The ESC would shut down because there were so many amps on one ESC because he had two big Astros in addition to the large props.. That's a recipe for a thermal shutdown. 

If he had one ESC per motor and smaller props (1 1/2"- 1 3/4" max) he wouldn't have that problem with the 208D's. I have those ESC's in two boats and absolutely love them!  Even when my other motors were running hot the Astro ESC's were as cool as can be.

-Rich.

Status: offline 		I can't answer that Carlos since a motor drawing 50 amps continuous is not very common in RC boats. i know you are running one big motor in your PT. you might check Novack for an esc, also I don't know if you are water cooling on your esc. as well as the motor.

Thanks Dauntlessfan,

This is the type of performance I always dreamed of for this boat. Thanks to all of you for the inspiration that helped me bring this dream forward.

The sound system still needs work. It needs to be properly grounded and the storage doors on the transom need to be installed so the sound can be let out. It currently sounds muffled trapped behind all that mahogany & epoxy. So far, this was the first time I turned it up during a run because it can be annoying listening to the feedback. One of the good things about it is that once you shut down the volume you don't hear it. I don't think I would get another one especially since the Astroflight motors sound so darned good as is.

I think a session at Binney is inevitable. I do think that the Empire State clan should push forward with each Sunday until the pond freezes but that's just my opinion. I'll try to get down for a wrap up session but I have been really busy with other things to make the trip. I'm glad the Baron is doing good. I cannot wait to see it in person. We'll have to meet up very soon.

-Rich.

Rich - thanks again for the pulley. Hung it on the davit tonight, shines like a jewel. I totally dig it!

I just received an email that the drive shafts I ordered were shipped today.  I'm a little disappointed since the last email received said they would try to get them out Friday but if not them "Monday for sure".  I suppose they can suffer from personnel problems like most other companies.   Meanwhile I've been working on the motor mounts.

Status: offline 		Hi caps...

Between yesterday & today I found a good crew of people that will ride aboard the Dauntless. There will be 3 men in suites along with a few elegant ladies aboard. I'm still bidding on the captain & engineer but won't reveal who they are are until I have them. All of the people will be in 1:18 scale because it is currently too difficult to find a decent crew in 1:16. I think this will be a good mix of people that will play the part of the modern 1940's-50's wealthy. I'm sure I will add more people later on but this is a start. These little figures add up fast! The Dauntless will be set up as a diorama so each room inside & out will feature people going about their business on the boat. Each room will have a story to tell.

Pics will come once they arrive.

-Rich.

I read, on another forum, "the closer the prop to the rudder the better."  He then went further and stated "to try to get the prop no closer than 25% of the prop diameter".  You can check it out here and maybe PM the writer with any further questions and let us know the answer.  http://www.rcgroups.com/forums/showthread.php?t=701900&highlight=prop+rudder+distanc

Another point I just read, the closer the prop to the rudder the more responsive the boat is to rudder commands since the rudder /boat only responds to moving water.  Hmm, something else to think about.

Captains,

My drive shafts have arrived, time to go to work.
