Tournarocker Diversion Build

[9W Monighan]

Well, the gearmotors turned out to be way underpowered so I found some stronger motors on ebay that put out 839gcm 21.6amp stall. I need to get some capacitors on them because they're glitching some. One problem with the new motors is they put out 16,200rpm vs. the 4000rpm motors. Now the Rocker goes too fast at full stick on the radio. I may get some larger reduction planetary's if I can't just limit the joystick travel on the DX7 transmitter.




All I had to do to adapt the new motor was gring down the long motor shaft.

I spotted the Tournarocker running around my shop this evening. I did another planetary change from 14:1 to a 27:1. This slowed it down more and now I don't have to keep the travel set so low on the sticks. I also added a Li-Ion 6600mha battery pack that fits under the hood. I had to finally cut the original plastic motor out to make way for the battery. I better get some more done on this so it will be operational by Jan 13th.

I have to agree! I've been patiently waiting to see this thing in action.

Here's the video. I would like to take a day and get the dump hoist installed, bolt the tranny in and make the hitch correct.
I just don't work on this that much.

Glad you like it guys.
The 04' CRF230 is my kids. The dog is my buddy but he gets too dirty running around the shop. Wife and I had to get a new kid now our boys are grown up

Had time today to hook up the RC4x4 winch that I'm using for the dump hoist. Looks like it will work OK for now.

Works well. Good job.

[9W Monighan]

I got my hitch made up. I had to machine one since the original one was missing.

This machine is just too cool! The old-school 1:1 and model are both so unique they just stand out from the pack of other machines. Great job!

Looks & works pretty good Steve. Quite an unique toy conversion.

Looking forward to seeing this thing run around the dirt pile. How much dirt does it hold, like a gallon sized ice cream pail?

Thanks Ken, We had one of these (1:1) at our steam show last summer and after seeing it operate I just had to do a conversion on one of these vintage toys.
Scott, (SmallHaul) caught it on video.

I hope the stock tires perform. I may opt for some 1.9 RC4x4 tires but I don't like the tread pattern. There is one with the chevron, but it doesn't look vintage enough. I should,like I said before, cast some replicas of the originals like Tom did on his triple 7 dump.
As far as capacity, I put 4- 12oz cup full of sand in the video but it will hold more if the material is wet. Here are the dimensions of the 1:1 9'-6''w x 4'-9.5'' max depth x 12'-5'' long and a capacity of 18ton. I figured the cu. in. of the bowl on the toy but I can't find my paper. This toy is really close to 1/16th scale.

Steve-this is really a unique model! After watching the video I wondered what you were going to do about the hitch but I see you fixed that little problem. Nice work!

Thanks Tom, Now that the hitch is on I discovered the tractor is just alittle too front heavy. When I turn the tractor 90deg. it turns over like a tricycle does. (as seen on my videos) yesterday I added about 3/4# of bar solder in the hitch frame. This helped some but I guess I'll have to add a few ounces to the rear axle now. This isn't a problem when the bowl is filled with dirt, only empty and while turning tight left or right. Maybe a smaller battery would fix the problem but I want a long run time , which I'm getting with the 6600mah battery pack. I had it outside my door at my shop in the grass and it did fairly well until the skid plate hit some big chunks of grass. I ordered some RC4x4 1.9 Mud pluggers to see if they would be an improvement to the solid hard rubber originals and add some lead shot to them for more weight. They may be too big though. I might have to resort to what you have done on the triple 7.

Really nice work, Steve.

The Joal smaller scale version of this model was definitely one of my favorite toys when I was a kid (oh ! wait a minute.....I think I'm still a kid )

[modelman]

Steve-I saw the Tournarocker turn over in the video but I wasn't sure what happened. I figured the dog tipped it over. Do you need softer tires or a different design or both?

[Lil Giants]

Did you order four tires? Steel wheels & lead shot for the rear axle may cure your tipping problems. A little taller tire is better than smaller, better ground clearance & longer footprint for better traction.
