Fumotec 490
 

So I finally bought one and it arrived last week

http://i721.photobucket.com/albums/w...h/IMG_0514.jpg

Ordered a 6 valve block from Premacon, a quick coupling from Fumotec and his new rotating screen bucket - still to be delivered
I've started to assemble some parts, then I will take it all apart to paint it.

The only thing I'm missing is a battery I would like a lipo but I'm unsure what to buy? The heavier the better as it will be mounted in the counter weight.

Re: Fumotec 490
 

Congratulations looking good forward to your build

Re: Fumotec 490
 

Congrats! You will enjoy assembling it!

The Li-Po I use for mine is 3S 5000mAh. Cont. 40C/Burst: 80C

It's 15.5cm (6 inches) by 4.5cm (1¾ inches) by 2.5 cm (1 inch) and just fits in the counterweight with some room left over for the wires.

Re: Fumotec 490
 

WOW!!! Congratulations Calum, quite an enjoyable model to put together for sure. :cool:

I put in a 5 valve block & it seemed to spread nearly the entire width... 6 will be tight!

I also use a 3s 5000mAh lipo from Team Enrich-Power that measures 135mm x 42mm x 28mm

The hyd pump that comes with this model is ridiculously fast & with such small bore cyls, cycle time is very quick! even with the motor rpm at 50%. I set my pressure to 18bar, seems plenty to keep the model planted while digging.

Good luck with the build, hope it goes together easily for you. :)

Re: Fumotec 490
 

Yes so far its been excellent to build, everything fits so well and looks well made too!
I asked Frank about a 6th valve and he said it should be fine, hopefully it will work for me..
I remember you saying about your's been a little quick did you ever change anything or do you just use it like that?

I shall have a look at that battery too

Thanks Calum

Re: Fumotec 490
 

So far so good!

Okay, I will have a look at that too. I plan on making a box/mount for it to sit in behind the valves if I have enough room

Regards Calum

Re: Fumotec 490
 

Slow progress from the weekend but paint has showed up so after a first assemble I will strip it back down and hopefully paint and assemble the undercarriage

Re: Fumotec 490
 

More progress this weekend but sadly not very much! I've assembled my tracks but i had 2 links missing so an email to Frank and he's sending me ones to finish them off

http://i721.photobucket.com/albums/w...BD1AD26158.jpg

I've primed all the metal parts for the undercarriage and I will hopefully put some colour on them this week

And finally a picture of my valves and pump on the base plate to check what space is available for mounting my electrics

Re: Fumotec 490
 

Nice photos. Thanks for sharing.

Re: Fumotec 490
 

Hi Calum, nice/interesting to see the progress pictures. Looks like the finish of the various pieces has improved too from when I build mine.

That valve block sure looks impressive!

Note - I know the upper rollers are just installed temporarily (pictures posted )9/23), but be aware that the shorter end is supposed to be to the outside. In the pictures you have them alternating. That way your track will not track.

Here a picture of what I mean:

Re: Fumotec 490
 

Yes I noticed looking at other peoples pictures their metal parts seemed to have a lot of surface rust on them
The valve block really is an excellent piece! Its a premacon block and weighed over 400g without the the servo's fitted

Good spot, I hadn't noticed that I had to file out the holes to get the bolts to be a looser fit. I will swap them about when I rebuild

Re: Fumotec 490
 

Undercarriage mostly assembled - I'm having some difficultly programming the ESC for the track drives can anyone help?

Re: Fumotec 490
 

Hi Calum, what is the exact problem you have? I remember having a hard time myself. One of the ESCs has to run in reverse to the other. I could not get that to work, for some reason the ESC kept reverting to the default program. Ended up reversing the input in the radio.

Re: Fumotec 490
 

I can get the track to go forwards and stop but cannot get it to reverse? I assume i'm following the programming correctly but its a little vague..

Calum

Re: Fumotec 490
 

Hi Calum, sounds like you are in Air/Heli mode which doesn't allow reverse. Needs to be in Car/Boat mode. Is kind of explained in the manual how to do it.

Re: Fumotec 490
 

Got it sorted now had to read the manual over a few times before it finally made sense. It tracks really well i'm still amazed how heavy the undercarriage is compared to my old stahl machine

Calum

Re: Fumotec 490
 

Yes, that manual needs some reading to make sense of it. Took me a while too to get the tracks working properly.

By the time you have the whole excavator assembled you are looking at a good 20kg. Not the easiest thing to carry around. Already put a couple of nice dings in the doors here. :rolleyes:

Re: Fumotec 490
 

Due to buying a house and having to move, I've hardly touched the excavator but this last week or so I found some time to continue on with it
I wanted all my electrics to be in one place and be as neat as possibly so I built this

http://i721.photobucket.com/albums/w...h/IMG_0758.jpg

The slew, pump and aux ESC are mounted at the bottom, then the top part has points for positive and negative connections. My receiver will be mounted to the top part as well.

A general look over the machine

I'm still waiting on a battery, trying to find a good quality Lipo which is suitable for my machine hasn't been easy, also buying from Europe seems to impossible due to laws preventing postage. So i'm just waiting on someone getting back to me next week about one which will hopefully do the job

Re: Fumotec 490
 

I have this lipo in my kat Venom 1552 3S 11.1V 7500mAh 30C Lipo
134 x 43 x 44 mm / 5.28 x 1.69 x 1.73 in got it off ebay

Re: Fumotec 490
 

Venom is a great brand, I use them in 4s in my 850. Everything else runs on 3s & they're all EnrichPower brand. Both 4s & 3s batts are 5000mAh. A lil on the pricy side, but very reliable, not a moments trouble with any of them, charging or using.
