problem help!

hi there,

i am having a problem with my cat sx.

yesterday day i bought a reedy 5000mah 40c+ from my local model shop. it fits but with millimetres's to spare. i am having a problem getting the plus bullet connector into the socket.

here are some to pictures to explain

we are confused on what to do. we did think about getting the dremel on the hole and making it oval but would this weaken the top deck?

has anyone had any kind of problem like this and how did they over come this?

many thanks

lewis

hi there,

it nearly goes in but it needs a bit off the hole. im worried about if i take some off it might weaken the top deck.

has anyone got some pics of how they solved theirs?

many thanks

Well you don't have std lipo strap and that's what doesn't let you push battery more in so you can plug it in.

An easy solution might be to solder the bullet at a right-angle to the speedo wire, plug it in before sliding the battery under, clip it all in place then finally plug in the negative when you're ready to go.

no i don't have the std battery strap but this one has a side bit which pushes the battery into the car and the battery won't go no further because it hits on the motor clamp, you can see in one of the pictures.

he is a picture of the custom battery strap with my old battery fitted, the plus connector fitted fine.

many thanks

we did think of that but it would be a job getting it under the belt. it would work if you could buy shorter 4mm bullet connectors but i don't think anyone sells shorter 4mm connectors.

i think the only thing i can do is dremel a little off the hole in the top deck.

but will it weaken it?

many thanks

Using a smaller spur and therefore smaller pinion to move the motor further back whilst maintaining your overall ratio, may give you the clearance you require.

thanks for the advise.

it might work but schumacher have not designed the battery location very well. you should not have to alter your gearing just to get the battery to fit. seems like the cat sx has a tight tolerance with electrics.

what about the newer sxII top deck, am i right in saying it has a wider hole in the top deck? i looked on their website and it looked wide but the picture is sometimes not true.

many thanks

Perhaps the battery manufacturers have not designed their batteries very well if one fits fine and another doesn't....

Using different internal gears (I mean std 33/23 ones with different combination) will help you using same final ratio just with different pinion and that should help you move motor rearwards. Anyway I don't use have issues with battery.

The SX2 top deck does have a wider hole for this exact reason, not all cells have the connecters in the same place. With SP/Similar cells, the connector would be directly below the hole.

Your options are either dremel your current top deck or fit the SX2 one. I wouldn't have thought dremelling it would cause any problems with strength. There's no need to start playing with gearing to try and fit cells in

thanks tom.

i have got the dremel to the hole and i have made it a bit wider. i can get the plug in but i have to lift the battery up and at an angle to get the plug in. i will take a picture.

many thanks

hi there,

i have taken some pictures of the attacked top deck. it is alot better but i think it needs more off but looking at the pics do you think i could take more off or is it getting abit thin?

the picture below is with the battery laying down and as you can see it doesn't quite line up

the picture below is when i lift the battery to an angle. in the picture i can get the plug in.

so do you think i can remove some more of the hole?

many thanks

why dont you dremel your custom battery strap and move the lipo over!!

ray carey · #16 09-01-2011

would a top deck off a SX2 be better, it has an oval hole.
