Re: RC4WD Excavator
 

Hey Joe, valid point on batteries. Have you seen this new lithium ion battery?

Probably not relevent, but it's new. For RV's & Large truck's.

plz continue to post feedback

Re: RC4WD Excavator
 

Not alot of time for tinkering these days, but something I did last night was connect my 5amp/30v power supply to the HK hoe with the volt setting @11v. Tx EPA @22%. The pump running thru the relief valve maxes out the 6amp meter in a flash! Either the stick or bucket moving by itself, the pump draws more than 6amps. Either the stick/bucket together or the boom by itself (two cyls to fill), the pump is drawing 5 to 5.5amp. All three valves flowing, 5amp draw...

Maybe tomorrow I'll try my 850 with its Graupner 600kv bl motor on the power supply for comparison.

Re: RC4WD Excavator
 

Hi Joe. Now that you've had some time on the machine, what are your thoughts about it. I myself would like to order one and anything you can think of would be great to know. Just like, is it good value and do you think it will hold up over time.
Thanks Rob

Looks pretty cool but doesnt sound right

Re: RC4WD Excavator
 

Is there anymore feedback from people who have bought one of these excavator? Im tempted but not sure if its worth saving up more and going to another make.

Re: RC4WD Excavator
 

I read today on scale4x4 that some norweigan guys just got their excavators and they noticed a leak from the valves, they did leak where the servos goes.

Re: RC4WD Excavator
 

Went and checked out the site today and noticed there are 2 more videos posted of the exc and the price was $2,499.00 it now has gone up another $100.00 to $2,599.00

Re: RC4WD Excavator
 

I got mine direct from Hong Kong, which is why the $400... and it was $450 for me to western Canada.

I did some tinkering with the hoe yesterday, making minute turns back & forth on the press relief valve. I think I have it set for optimum performance now so it still has good power & speed, but doesn't pull the model around so easily & the pump doesn't make so much noise, drawing high amperage. The ten foot length of 14 guage wire from the car batt remained cool to the touch after 30 min of continuous digging.

I look forward to getting the Spektrum DX10T radio this winter and this hoe will be the 1st model on it. I'm just not having any luck programming mix or expontentially with this chinese radio for smoother, more fluent motion than I'm currently getting from it.

I see on the RC4WD site that they currently have 6 in stock, better get one while they're available.

Steamer, I think I'm going to keep mine for a long while to come.

Re: RC4WD Excavator
 

Got an e-mail from RC4WD today, and the excavator hydraulic pump's are back in stock.

Hope this help's! Later, Neil#2 aka doodlebug.

Re: RC4WD Excavator
 

Well I've been kinda iffy on getting the excavator for the heat issues and pump strain noises Joe has talked about but I decided to bite the bullet and go for the pump and electronics out of it so I will give you guys some info after I get it all and get it set up and running. I'm not sure what all it will be powering as of yet but I thought I'd give the pump a try at only $130 it's worth a shot.:confused:

Re: RC4WD Excavator
 

Say Tyler? I think the greatest downfall with the HK's pump/motor is its direct connection to one another. Perhaps it should be more like Vario's solution. What does that ratio look like to you? 3:1, 4:1

Re: RC4WD Excavator
 

Hey Joe, my horrible tooth counting, is closer to 3-1. Thank's for the link.
Cheer's, Neil#2 aka doodlebug.

Re: RC4WD Excavator
 

Hi,

Anyone else brought this model yet? any more details?

Thanks
