I got a hankering for building something interesting.

I'd grown tired of my LMC chassis with Trekker bits as a Crawler Bug. The wheels are hand spun by Danally and the tires are gold.

And tired of my Wroncho Bro Dozer.

So I hit the Google button and scoured the forums. Then rediscovered the GMade R1 and Fungi talked me into his Goat V1. Orders were placed and the two chassis' arrived within a day of each other.

So the wrenching began. Both are in the same state of needing body panels and electronics mounted right now.

LMC chassis flexing abilities.

The Goat is virtually identical. My camera skills are lacking, but it's the same block of wood and the three wheels are still planted.

The Goat is significantly lighter and I will wager it'll prove it on the rocks vs any metal plate chassis rig.

Being forever in a hurry, cheap, and lazy. I opted to try the steel rod/wire links. The only place I could quickly source the suggested 0.062" wire was fleaBay...in the form of Muskie leaders. Order placed and on hand. I made the initial links with threaded rod from the Bug project. With the lengths sorted, I made a jig.

I now have identical upper/lower links. I used a drop of Gorilla Glue on each one.

I had to extend the driveshafts, too. Mad at myself for not predicting this, I tore my project room apart and found a nice and easy fix. I have some carbon arrows I cut up and used making a micro sponson boat. With enough force pushing the shaft in, the friction alone will hold it together. So I chucked and trimmed the female end in half. Measured out the amount of arrow needed (25mm), and made it happen. A small pipe cutter will make short work of carbon arrows. No pics of the shafts but I'll take some if anyone wants them. Pretty simple like the ink pens or tube from LHS.


I haven't decided on what wheels to run on the R1, but the HPI tires are almost a match. I also haven't decided on a paint scheme for each one. I'm wanting to make them twins but don't know what color yet.

Jim had supplied some white braces in the kit. I wasn't too keen on the white and looked around the house for a replacement. I found one in the form of an old black antenna from the 27mHz days of yore. It worked quite well, too. I rolled the antenna under my blade until it cut through. Then pushed my post hole maker in the end and spun it backwards to open it back up.

I put some 'chalkboard' matte black vinyl on the body panels until I can decide what to do color wise. I then stuffed the electronics in for a test run around the house and it did well on Legos and Paw Patrols. I've finally gotten a decent soldering station and hope to clean up the wires soon.

It does quite well. I have the tires heavily weighted and it'll just about stand up completely vertical. But when it does turtle over it stays that way.
 
I finally took these out this morning. They both did very well. Only real issue was the 1:10 tires were entirely too soft. I had some foams for them and just never put them in. They're in now and I'll head back tomorrow and see how they do.

Here's my iCrap5s pano pics.

And the 1:10 counterpart

For the Goat: Trekker axles, extended Trekker driveshafts, and the Trekker tranny/motor. All stock. The ESC is a 10a Chinese one from fleaBay and the Rx is a dehoused Spektrum 3 channel, SR301 or something like that. I've got a dx3e I use with this and with a Losi Micro Rally with an Orange Rx. So it's only left/center/right on the rear steer. I've been meaning to swap the outermost wires on the rear servo and tie them together so it'd be full time steering.

The rear axle has Losi parts to match the front axle. Both servos are cheap Chinese MG servos without a servo saver.
 
I just did one, if you are using low draw servos, this rocks !

Bastens Quadsteer

Works on 2 or 3 channel Rx


HANG UP AND DRIVE !



That's a neat setup. I think it'll be too big for my 1/24 though. I have to wedge a battery into the cab of it right now. I'll try to reconfigure the electronics and see how that works out.
 
I took the Egg out this morning. It fared well but with all the lead shot in the tires was prone to bouncing and roll overs with steep inclination and wheel speed. I'll be revisiting the weight issue soon. If there's no need for wheel speed it just crawls over it like an ant. Lifting a wheel when side hilling led to rollovers, too.

Long time no updates.

I’ve been beating my Fungi Goat off and on for quite some time now. Well finally the motor has gotten sluggish and the heavy tires ain’t helping. I’ve been looking for a replacement motor with a longer can and have yet to find one. I’ve ordered from fleaBay China and they’ve no showed. Got my money but after waiting weeks to months it’s quite disheartening. So I drug out the Barrage tranny tonight and robbed that motor. The holes are backwards so I drilled some new ones. Bolted it up and voila. My quick spin around the house seems quite promising.
