What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[George B]

Put some GM cooling system tabs in and went for a ride. I get a smell of antifreeze when hot and it is most strong by the right tank. Thinking its seeping. Gonna try this and see if it helps.
I also tidied up the catch can. Drilled and tapped a third mounting hole in the top of the can and installed some 45° elbows for the hose barbs. It is already catching stuff.

Oh, and i feed that rc a little nitromethane.
I have a few gallons of 100% stuff on hand...

Been holding my self back with it, i really want to see how my vette handles it.
I just don't know if a wide band o2 sensor can see it correctly... lol

Nice.
I still have all of my rc stuff.
I got into nitro when i was 17.
Pulled it out during the covid crap last year and decided i missed it.

Nitro kinda died within the last 20 years it seems.

But I'm pretty happy with this 1/5th scale gas stuff.

Yeah I did the Nitro thing, don't miss it. Really like the 2 stroke regular gas thing there. Pull starter. Wonder how it would run on this:

I run pure gas, and i use redline two stroke oil at about 20:1
Mix in 3 cap fulls of pure nitromethane.

That's about the max i can get away with so far, beyond that it becomes very hot... lol

Nitro rc is a pita compared to an actual 2 stroke
You can mix the rc car fuel into gasoline, but it's very ******* the rubber parts.
And the oils separate in the gasoline.

Pure nitro has no alcohol, and no oils.

I have been running it in my leaf blower and chainsaw for a few years now.

My leaf blower is amazing.
The chainsaw revs crazy high if you don't watch the throttle... lol
Night and day difference, just a little goes a very long ways!

I recently bought a 1/24 crawler for messing around in the back yard and while camping. That scale so it’s easy to pack in with everything else. I also discovered it rides on the dash pretty well. The charge on the little lipo pack is amazing.

plus it’s a Chevy.

Heck yeah! That thing is sweet. Nothing like what these guys have / had, but still fun. I bought one after you posted it, and its a blast. I had to get something a little faster though too, so also got this one: https://www.horizonhobby.com/product/1-18-yeti-jr.-can-am-maverick-4wd-brushed-rtr/AXI90069.html

I built this truck about 15 years ago. Battery is under the bed, jumpers are ran down low in the wheel tub

Just a thought to save from removing the front clip

I just have to pull the bumper to replace the battery. It’s 4 bolts. Probably won’t need to do it again for many years. I’m telling you, I don’t even have room for it under the bed. I have a 7 gallon air tank, 2 compressors, fuel cell, Airlift manifold, and the frame is only 4” tall on a SFBD. I don’t even have room to run an exhaust pipe past the rear axle, things are tight. It’s fine where it is. Plus I just finished pulling the bed, running all hard lines and wiring for the Airlift 3H system and painting the frame.

Make sure the new tender has a desulfarator mode- Batteryminder tenders have this.

It does, it’s an Optimate.
