Rthalls - I don't know of a Dauntless hardware kit that comes with 2" props, or any props actually. Which hardware kit are you considering?

If that's the Dumas hardware kit, you may want to look at the MACK Products hardware kit for the Dauntless before you spend any cash. I'm not saying the Dumas stuff is bad, just pointing out that there are other options. Here's a link for their site:

thanks for the information , trying to get prices on everything [ sticker shock ] makes the boat kit cheap........new to boats been building airplanes for 35 years

Okay now I see, thanks. When I built mine, I bought kit 2332 which doesn't include props. Also like Hydro said there are other options out there more well suited to stronger motors like the 700bb. I replaced my Dumas shaft struts with MACK brand and most builders here use the heavy duty couplers offered from harbor models.

DF, I'm not familiar with Harbor Models. Do you have a website for them?

i was just looking at that dumas hardware kit that is a old kit i had the same one i called dumas and they had me send the struts and props to them and they replaced the struts and upgraded to the new props for free.they told me the old struts were weak so now i have 1/3/4 new props and better struts.the new props dont use drive dogs

Deep,

Were they the ones you already had on the boat, the painted red struts? Was that their kit #2341 which comes with props or kit #2332?

Silly question. Must have been hardware kit #2341 because you said you got new props, duh.

enjoy reading these hints , I just started my build of the dauntless and getting some of the parts together . I have two 700 brushed motors and a 12v lead acid battery but don't understand all the different speed controls ? I know I need a brushed control at 30amps but where , the more I look the more confused Iam any help is appreciated............. thanks

dauntlessfan

RT - for running two 700 motors you'll need equipment rated at more than 30 amps total continuous. I tried a single 30 amp speed control on two 700's and it only lasted a few short runs in the Dauntless before permanent failure.

The ideal setup would be two electronic speed controls (ESCs), one for each motor. Check out mTroniks marine ESCs. They're rated by continuous amps for output and voltage range for input. They're waterproof and come with a good warranty. And they're not too expensive.

If you go the dual ESC route, be sure to read up on how to wire it here in earlier posts to avoid damaging any components.

thanks again and after checking it I still have no idea what there numbers mean or what I need

hi df i think you should tell him what yours are as i think you went with the 40 amp vipers dident you

dauntlessfan

My boat has a "Viper 40" on each 700-sized motor to control its speed.

The 40 amp continuous current limit means it's rated to handle 40 amps for long periods - so the motor it's controlling should draw less than 40 amps at full throttle under load (i.e. in the water pushing the boat). For this spec, a larger number means a more robust ESC and more powerful motor options.

It has 6-12 volts input voltage. That simply means the motor battery(ies) plugged into the ESC must stay within this range. For this spec, a wider voltage range gives you more battery setup options. You mentioned using a 12 volt SLA battery so you'd be fine. 12 volts is the sweet spot for 700 sized motors in this boat IMO.

hey df you dident tell me how you liked your escs you got the 40s i got the 30s as im still waiting on batterys

dauntlessfan

Deep the ESCs I got are great. Easy to connect and calibrate, run cool to the touch, waterproof (my toddler poured a cup of water over one of them and it still works fine so I've tested the claim). So far so good!

deep sky

great i have set mine up and run them on 9.6 they seem to work great the only thing i need to do is trim out the motors as one does not start at the same time the other does not by much ill play with that on sea trials when my batterys finely get here

when using two speed controls , do you Y harness to the thro. stick of the RX ?

Hydro Junkie

Now that depends on your radio. Some you will have to, others you can use separate channels. If you're going to use two channels for the throttles, a twin stick radio would be the better choise

WOW I just got the hull painted the way I wanted. Been a long journey to get to this point but I love every minute working on her.Lets see if I can post a picture.

wagonman2,

The finish looks AMAZING!  I could almost see my reflection.[X(]

Hi Wagonman- Boat looks fantastic! Was wondering what you were up to.
