Ace's Hydromite Build

[peells]

Hey do you have the hatch made yet? well whats taking so long? it is Friday.......LOL

[ace028]

Well, I went to michaels and bought the wood for the hatch, as the kit only came with the peices that are a template in the drawings ( I will have to measure a few peices and tell them at lazerworks to include them in the kit) The boat will probably sit for a while after this weekend, I need to get the motor, witch I think is going to be a eflite outrunner 420, I will water cool the motor mount to help draw heat out of the armature, but I will have to use brass, since I don't think that I can solder aluminum. Well I better get ready for work, I'll post some pics tonight or tomorrow.

I have started on the hatch, I also added a rounded peice to the front of the tub. The hatch is rough and will need some fine tuning. The pics are not the greatest, they were taken on my cell phone, I need to charge my batteries for my digital camera. Tell me what you think. I also orderd the motor, its a eflite outrunner 420. hopefully it isn't too hot of a motor, its 3800 kv. I may have to add a fan to help keep things cool, but I'm not going to worry about it yet, I want to get the hull painted up and I will worry about the other stuff as I get to it.

Here are a bit better pics, I havne't really worked on it much this weekend, I've been lazy. I think I may re do the hatch cockpit. Its hard to make it symetrical buy carving a block of balsa. What do you think?

? on the 420 outrunner motor. I thought outrunners shell revolved and the inrunners shell remained stationary so can cooling could only be on the inrunners! Also how many volts for the 420 > Reason at 3800 x 7.4 brings you 28120 rpm ; alot of power for a 16" boat. I think you'll be diappointed cause it will be unstable unless you go to a 1x4 pitch on prop or you'll get torque roll.

The shell does rotate, I was going to cool the mount that the motor mounts to, because you know that the heat will transfer to a less hot surface, and thats the only place that I can actually cool, it might not be effective though. Well I am going to power it with a 3 cell lipo pack, the renegade rigger is a little smaller (though it is wider) and has a 400 size with 2600kv, pushing about 45mph with a large prop and seems to not have torque problems. I haven't finished mine, but I have seen videos of the renegade run. here is a link

but if it doesn't work I can always change to something else.

Yeah, it probably is too hot of a motor, but hey it was only 30 bucks, so I couldn't pass it up. I think bl is alot cheaper in the long run, because you have virtually no maintence to do on them, and they are more effecient so you will get more power and longer runtimes, and the prices are starting to come down a little. But being on the edge with speed is exciting. I can always change the motor out though.

Got my motor today, heres a pic. Now I have to make a motor mount.

Everyone links to this video when talking about the renegade! It's cool because it's MY boat!
Ace, That motor should work well!

Thanks, I can't wait to drive it, I am still waiting on my dad to help me paint my renegade so I can drive that too. (I know he's busy working.....on his boat instead of mine lol)

Here I made a motor mount, which needs a little cleaning up, and I soldered a brass tube to it for water cooling, I think it will work ok. The mount isn't bolted up yet, its just kind of sitting there.

You can see where I accedently touched the balsa with the iron, opps.

[ace028]

I did some sanding on the hull, don't know if you can tell from the pic, I filled in a few spots with balsa filler. It needs to be sprayed with a protective coating, and sanded, primed to help see any spots that need filled. I didn't like my motor mount that I made, and the small kink in the tube, so I made a new one. I have to solder a tube to it still. I am also making a new hatch, but its not ready for a pic yet. Hopefully it will turn out good.
