My New Mini Eco! Set up tips?

[Rich]

Thanks for the tips guys. I just drove it a bit ago. I moved the battery up so the back of it was equal with the center of the servo horn screw. It handled very well in a straight line. Left turns it likes to hop still. I think I need to get a new lipo with a higher C rating. The lvc kicked in about a min of running. I will have to see with a better battery what this thing can really do!

Is she running cool? If it's getting hot, it would cause the temp cutoff to kick in. BE sure to check that as well. Another tip for the battery, I mount mine against the flood chamber wall, on it's edge. I put velcro on the wide part of the battery and also on the bottom edge. That way it holds the battery against the bulkhead AND the bottom of the boat. That concentrates more weight on the left side. The hopping in a left turn is probably because of torque. You need more weight on the left to counteract the torque roll, so it can't lift the left side of the boat.

Thanks for the tip! I just ran it again with the back of the battery just behind the servo horn. It ran really good, no stuffing in right turns and it hops less in left turns. I have to add some weight to the left bc it doesn't self right. I figure this will solve the hopping problem too. The temps were 95f on the motor 85f on the esc. I did notice more water coming out of the cooling system more often than not. I might end up lengthening the pickup tube just a bit to aid in cooling. I most def need a different lipo, the temp was at 137f! I know they can get that hot but with a new battery it would solve the heat issue and the weight issue on the left side. Of course this means I am going to get a slightly heavier battery

Temps are perfect. No need to mess with the water pickup tube! The lipo is a bit warm to be sure. Use a 3000mAh pack if you can fit it in there. That way you won't need to add as much weight to the flood chamber side.

In addition to adding weight to the left side, cut some bigger holes in the deck. This allows the chamber to flood more quickly and thus self right more quickly.

How about this pack? Will it fit? http://www.hobbypartz.com/77p-sl3000-3s1p-30c-3333.html

I'm not sure. You have the boat there, measure the area where the battery needs to go. The dimensions for the battery are at your link.

[Rich]

I think the width might be a tad too long. It may hit the cowl. What lipo do you use?

[martin]

The tallest you can get right over against the flood chamber wall & under the hatch lip is 37mm, slightly less if your moving the battery further back past the servo. I use a 34mm wide lipo & it just goes under the lip. Martin.

I order the Skylipo 3000 mah. I should be able to fit it in if I lay it down.

If you have to lay it down which i suspect you will have to + its a much heavier battery then you will have to add more weight still on the chamber side of the boat to get self righting as your moving weight towards the other side with it layed down. Martin.

That's what I figured would happen. I'm not too worried about adding more weight to the hull since I do run in somewhat choppy water.

I final got to run the eco with the 3s 3000 mah sky lipo. I have to say the extra weight really helped the handling! It doesn't hop as much in left turns nor does it dive much in right turns. I still need to add weight to get it to self right. This thing really hauls A$$!!! Now if only I could get my Gecko to run like this. I'll keep you all posted.

[sailr]

Did you ever enlarge the holes in the flood chamber? You may have enough weight on the left now but the flood chamber needs to be able to "flood" quickly for proper self righting. Can you post a pic of your boat?

[Rich]

No I haven't. I have one hole in the top and thats it. How do you guys cut holes in yours? With a knife or a drill bit. I can post pics later.

[martin]

Be carefull when drilling as you can split the deck quite easy as the glass is very thin, Also watch the drill dosnt bite as it can pull the drill & go through the bottom of the hull as well especialy if your putting larger holes in. Martin.
