Tuber built from Hangers & QLO's & DIG

[DANALLY]

I had to use an old TQ3 receiver and radio. I decased the receiver to fit.

The DIG.

Used shocks in droop with no springs. I added the hair ties to act as resistance. My 7 year old thinks she owns it cause she donated them.

I used a sidewinder micro esc set up for brushed motors. I am running a 90t Getbent motor. So sad to hear he isn't doing them now...i hope things work out so he does. The motor is almost perfect. I was just ready to have him make me a 100t.

I am not completely satisfied with the side plates or the last minute hood. It is my first one though and now that I got the welding and bending down i plan on building more. (and one for a stock wheel-base set-up too)

The QLO's have about 75bb's in each front tire and 40 in each rear. Total weight of the rig is just over 1 pound.

Custom steering links.

Just the frame...coat hangers are fun to work with!

As always...a flex shot.

So far I like this one alot. I was just so tired of bodies. Next step is a 4 channel one where i can do a 4 wheel steer and dig...the rig will have to be a little bigger to fit a bigger battery inside the frame. I also plan on trying out a bigger can motor. I love a challenge.

lookin good its f'n huge lol

 

[crawlerknownothing]

that rig is crazy. I really like the tuber look. I like the dig. I wish I knew how to do it, would like to install it in my own rig. Great build. Keep up the good work. "thumbsup"

Whats the wheelbase on this beast? I like it so much I want to do that with mine. Maybe a little smaller. Idk.

 

[forsakenrider]

I want to see the mechanics of the dig unit!

 

[getbent]

Good to see you back DANALLY. The rig looks great! Did you weld or braze the coat hangers together? Also, I would like to see how you did your disengage mechanism on your dig, I have all the parts for one, just havent put it together yet. Does your dig servo whine alot? I stole my dig servo from a micro heli, but it puts out a really high pitched whine all the time, not sure I can handle listening to that evrytime I wheel! Awesome looking rig!"thumbsup"

Coat hangers?? :shock: Right on man, that looks fabulous...

 

[T-buck]

Another Awesome piece of work.

I would love to see video.

Thanks!

I will load some more pictures and a video on Thursday evening or Friday. I welded the tubing with oxygen-map gas and those metal welding rods from home depot as filler. My servo is totally quiet. I hate how expensive those micro servo's are. I paid $25 for one. It works well though.

I will also do a video that might shed some light on the dig unit. It is my first one and the materials I used will most likely change for the next one. It's hard to find a small hinge for the lever part of the dig so I had to make one. It's not very clean...but it works.

It's just under 140mm. I had it at 130mm with the front end pulled in. I liked it better with the longer front links and extra travel.

well now, this rig is fawkin hot!! great job! "thumbsup""thumbsup"

 

[Fungi]

Do you have any images of the process. Before and after brasing and before paint? Would be interesting to see. Nice job!

I will try on the next one to document it. This one was just so unknown on how it would turn out that i took no pictures.

Nice build, how bout that video? How does it climb with the weight balance more towards the back?

It climbs well. It is hard to compare with my other micro's just cause the wheel base is so long. That helps a lot on the balance. The wheel weight in the front is pleanty enough to balance the rig also.

I need to do a video but have a few problems...bad weather, batteries are all dead and the charger blew a fuse which would mean a trip to radio shack. Therefore I took the rig apart to change a few things. I am re-doing the rear tubing to fit a bigger battery, adding an endo hoop on the front, and changing the color.

I am going to do a few quick video's while it is apart to show the dig operation and a little of how i welded the frame. I should have some video's loaded by first the week.

Sounds good, Really intrested in that dig. "thumbsup"

That thing is incredible, Im still tryin to wrap my head around you built that thing,"thumbsup" nice!!!

Dig pic's

Here are some pics of the dig with a new arm that now replaces the plastic hinge system. It is much cleaner and works very well.

This is an extended driveline with a spring to push the brass tube sleeve over the trany output shaft.

You have to drill out the drive line for the brass tube to fit in. Then drill a hole through the brass tube where the existing hole is in the plastic drive line. Confused yet??? The brass tubing is 5/32 x .014 from a local hobby shop. The length of the cut peice of brass is 8mm long.

I hope you can see where the hole is drilled through and a factory driveline screw is installed. This screw contacts the cut in the trany output shaft.

I flipped the trany and the longer output shaft now is the rear drive. I like this for the fact that the brass tube has more material to hold the driveline on.

Cut the output shaft at the hole so that there is a slot / split at the end. If i remember right there was a nub that i sanded off so the brass would travel freely on the output shaft.

This cut out is where the screw inside the brass tube contacts for drive mode.

The servo plate is thin aluminum bent and drilled to bolt onto the same holes that the gear cover uses. The servo is held to it with servo tape.

Here the servo is in normal mode. The arm is not touching anything on the driveline...at least not enough to cause any binding or interference.

When dig is engaged (on channel 3), it pushes on the drive shaft and the drive shaft just floats on the trany output shaft. As you can see it only moves a little bit to disengage.

The big thing is making the drive shaft the right length so it has just enough travel for the dig but not so much that the drive line can fall apart.

I hope this is a good start as a description. I will be doing a video soon and will try to zoom enough to get the operations of the dig. I tried to film it already and it was really blurry.

It's gunna be a while for a video...I tore it apart big time.

I ordered a 130 can 80t motor like the "BIG-BLOCK" build and it may require a few changes to the chassis to fit.

I am finding that once you hit a certain size and weight these little motors can't hack it. Even with the Getbent motor I seem to be underpowered. (no complaints to you Getbent!) When I run the Getbent motor on a rig with stock size tires it rocks...best motor to date that bolts right in.

My main problem is that after a few minutes of run and as the motor warms up I loose the low end power and control. It's almost like the battery is dying and the rig stalls out unless a lot of throttle is used. I added a temporary micro fan and it did help but there is no way i am going to be able to fit it permanently.

I am also making room for a 7.4 lipo 25c, 450mah. I hope it works well.

That is so sick!

P.s. Interested in selling the Getbent motor?
