Conversion advice

[dirtysouth31]

maybe the stuffing tube to motor coupler is out of line.cable should be in center of stuffing tube,doesnt take much for it to become a binding issue.

This was my build. It was posted on another forum.

That video is a shortened video of about a 4 plus minute run. I was using a converted jeti airplane esc with water cooling. was barely breaking a sweat after the run. To boot I went against all conventional wisdom(of course at my own risk) and was running at 1/2 to 3/4 throttle the whole time, with a quick blurt of the hammer, once or twice.

I ran a 14xl on 24 cells. I will be switching to a 12 or 13xl and 18cells soon.

The stripped Nitro MM .18 weight in at 52 ounces, with the radio, radio box and all the hardware. Not to bad considering the BARE electric hull weight 39 ounces.

Steven, what was your max speed on your 24 cell, 14XL setup?

[Steven Vaccaro]

I never got to gps test it. But the nitro dudes at the lake were fully impressed, which puts a smile on my face and it was much faster than my q mono which is setup and been tested in the 40mph range. It didn't turn very well. So I will be changing the MM to a 18 cell setup and lipo.

Ok, I am putting the 14XL setup with NiMH's in a larger hull and rudder. Hope that will take care of the weight handling issue.

Back on topic...
I believe I may have solved the lack of room for 12 cells in this hull.
The fwd compartment will house the batts & motor. The aft compartment will house the electrics. This Video will demonstrate the battery configuration & placement using dummy cells, then display the remaining room. Tell me what you guys think please.

Video <----

Video is 13M so please be patient while it loads.

Diego ,
I sent you a PM, As for putting everything in the front, Batts and Motor,,just be careful you don't get to bow heavy, I thought of something similar and decided that the weight distribution method I used really balences the boat well. Not saying yours won't work , just something to keep in mind .

[Diegoboy]

I hung out with some guys yesterday (nitro stuff) with Dirtysouth31. I saw this beautiful boat built by Don Ferrette. He set the boat in the water for the first time. I later watched it blow over and destroy the wing. It has front flaps that he put at a 45 degree angle to keep the nose down. On her maiden voyage, he forgot to lock the flaps, causing her blow over. I want to know what keeps the nose down on the proboat hulls. We don't have a curved turn fin like outriggers do. I was thinking that the batts will keep her nose down since I don't have them there flaps.

Nice boat, keeping the bow down and not burying it in the water can be a triicky thing, i almost had one today running in abot 20mph winds !
Adding flaps fo a bit of downward fore is not that difficult, just like adding trim tabs on the stern. I am considering it on my Llumar using a few thin pieces of aluminum.

Diego , 1 more thing to consider , once you have the coupler , motor mount, motor and connection wires , you MAY have limited room to insert your batteries, thats a problem I had when I first tried to put everything up fornt in the bow.

[Doby]

Diego; just got back from the pond , tried the Llumar on 14 cells,,,,whats that in my rearview mirror ?????? oh,yeah 3 of the local SV's,,,thats what

This thing flys on 14 cells:D

[Diegoboy]

Really? That's sweet! Do you have a vid or pics? :)

[Doby]

Nothing yet , but this aftrenoon I'm off to the pond with my Navibe GPS for a few runs,, I'll post the numbers later, I just got the GPS yesterday and can even manage to wedge it in the Llumar after some serious thought :D
