Any Progress as of late?

I'm a little curious as to how well those diffs are going to hold up.

I am still waiting on the brake components (linkage, and pad parts) to finish that up. I had the parts for the yusa on road project show up, so I put my attention towards finishing that. I still need to make the motor mount for the tmaxx and the battery tray, but a sunday should take care of that. Work has also been kicking my butt as we are very busy, and it is raining. After looking at the diffs I am confident that they will hold up with no issues. The cas design is better than the emaxx in that if it tries to spread apart, the pinion to ring gear mesh will not alter. The case is split horizontally, not vertically like the emaxx cases.

Ok, got a chance today to do some more work on the ol' tmaxx. I made a chassis plate to mount the rcm revo motor mount to. Used a piece of t6 6061 and drilled and tapped it. It mounts to the chassis with screws from underneath and the revo mount bolts to it from the top. It seems very sturdy so I am sure it will be ok. I also picked up a 3.3 tmaxx radio box. It mount in the stock location and just misses the brake pads, I guess the chassis is not symetrical and flipping it over made some difference. The radio box looks big enough to get my receiver and the cc bec in, which should tidy up the chassis alot.

This looks GREAT Linc!

Is that a 6XL?

lincpimp · 01.20.2008, 08:28 PM

Nope, it is a 20xl! I found it on ebay and paid 50 bucks, brand new. 834 kv, so it should run about 30k rpm on 10s lipo. I also got my Great Planes 60HV esc and prog card in. It looks well made and even comes with a deans connector already soldered on! The card gives some decent options, like timing and freq, plus cutoff voltage and motor reverse, which is handy caus e I like to hard wire and it can be a pain if you have to desolder two wires and swap them to ge the truck going the right way. I have given up on connectors for mtor to esc wiring, they just seem to cause alot of problems!

The 5mm connectors are pretty beefy. I've never had any issues with them.

That's a great looking setup. Very impressive on the motor. Are you planning on adding some cooling to it?

I want a 20XL also... I couldn't find them on ebay... you lucky guy...

lincpimp · 01.20.2008, 11:42 PM

I have only ever seen this one 20xl motor for sale.

I would personally like to see any of the xl motors above the 14xl. They look like a great alternative to the higher end motors. I have had great success with the lower kv l can motors on 5s and higher. I can only imagine how well the lower kv xl motors will work. It seems like their design and constuction shortcomings are amplified less by higher voltage. I am guessing they work better with less current running through them.

Sike, I will use a rc monster heatsink/clamp on the motor, I have a feeling that will do enough.

lincpimp · 01.21.2008, 01:01 AM

Oh, and about those connectors. I have decided to just hard wire my motors. I have plenty of motors and speed controllers so I just hardwire them up and they work better, or at least they do not develop problems later on. Had too many issues with the 4mm connectors, and the 5.5mm connectors are too big, and look funny, just my asthetic side talking there!

bumpy, hows this project coming along man?

lincpimp · 03.03.2008, 04:43 PM

Very slowly, I finished up the hyper7 buggy. I also had to move the rc repair station to my upstairs rc lair!

So I should be able to finish up everything quicker now that I have more room and do not have to clean it up every night!

I intend to get the hv tmaxx wired up and test it soon, and then make the battery trays and esc mount.

Plus I just got the brake linkage and lever last week, damn lhs taking their time!

its a year later, what became of this?

Pulled the diffs out and had them in a BPP torpedo for a while, recently decided that the topedo chassis and his brother would make a better platform for the 6x6 Maxx so I am in the process of swapping the front and rear assemblies onto a 3905 chassis with the better tranny and a center diff.

So basically the diff, bulks, and arms will be reused. I still have the tmaxx chassis w/custom extension and the spare torpedo braces hanging around. Maybe I will do something with them?

Also stole the motor mount to go on the 4-tec. And the radio box is somewhere else too...

I guess I aborted it. The GP esc was used in the hv savage for a while, but I plan to sell it off and maybe get another Lutach hv esc.

r/c life begins as soon as the first two parts are mated together. I'm normally not controversial, but I'm pro r/c, and I have to say something about this.

an aborted project is an r/c that never got a chance to bash.

i need to go to my quiet spot and journal...........

lol, R/C abortion? What's the next topic of controversial discussion; R/C politics, R/C euthanasia?
