CRT .5 Revamp - RC-Monster Forums

I had my outrunner .5 sitting for awhile, and I wanted to get it running again, sk I thought an inrunner setup would breathe new life into this lil thing. I got a jato and it came with 4 extra shocks and extra springs, so I took advantage of that. I also had to make a servo hold down out of a piece of the weakest aluminum alloy known to man. It works great though, and the 2-piece mount I got from Chris (thanks!) makes it look a little better. It's kinda like having a fat friend; whenever you're walking around with him it makes you look skinnier and more attractive.

no front bumper gives it the 8th scale buggy look

front shocks with white green springs, running brand new $8 HXT 12kg servo

rear shocks with red green springs

2-piece motor mount - this thing protects things from rubbing against the spur, great design

I'll be running a medusa 50-3300 with this baby, and I'll try the stock tires with this battery and see how it goes.

With the pro version extended chassis and 10th scale tires, it looks almost 10th scale next to the jato

I'm running after run oil in the shocks.(lol) Will this deteriorate the plastic?

very nice....seems like most are going w/the Gladiator tires these days

Looks good. I think some 1/8 buggy tires would look awesome...

Got er running today. I got the 36-50-3300 in the mail and dropped her in after a little dremeling. I "nested" the battery by wrapping it in a rag then ziptieing it to the chassis. It held up good, but probably made the battery heat up.

Temps were 130 on the motor, 135 on the esc, and 120 on the battery. The lipo was a flightpower 30c 3200mah pack. Pack was perfectly balanced at the end of the run, all cells at 3.3v. Runtime was about 6-8 minutes of hard running and the pack was only about 75% charged. Top speed seemed to be upper 30s-low 40s. Geared for 38mph.

I had a lot of cogging though, and bad steering. I need to get new knuckles as I modified the existing ones to fit different wheels, which messed up the steering. cogging. Start power is medium. I think it's probably just my radio acting up. It's a fm 75mhz futaba 3pm that showed 11.4v. I traded a nitro engine from a savage for this radio. Antenna on the car was up and motor wires braided. Check the pics. I'm running a bec at 6v. Should I consider a lipo for a lipo for my tx? I had shorter range then normal. I could take my e-revo a block away and get good signal. I'll change the bec from 6v to 4.8v because the servo may be drawing too much current from the bec to get a good signal... That might fix it.

Shocks were spot on. It seemed too firm on the workbench but it worked out just great on the road. The truck was about 4-5lbs, closer to 4 on my bathroom scale with the 3200mah 3s lipo.

Wheelies on demand too. Punch control on 10%; I could do rolling wheelies. This setup is awesome, no wonder so many people recommend it. Running 30k in the center diff because that's what I had on hand. Works great.

I was going to put the motor in my jato and run that 2lb beast first, but I didn't have the right pinion. If anyone has a 32p 5mm pinion 22-26t pm me. This motor is fast in the .5 I cant imagine how fast the jato will be.

Looks pretty good. You should mount the ESC behind the motor if you can fit it. And try to do something about those RX wires!

I have run the same radio with good success, you need to move the bec away from the rx. Put it behind the motor or somewhere different than where you have it. That should cure the glitching.

Also, move your antenna to the front of the vehicle, like off the front steering brace. I can see it getting lunched by the pinion... Plus getting it away from the motor may help with the glitching as well.

I have some 32p 5mm bore pinions in 20-22-24. Let me know, I will sell em for a good price.

Nice to see my motor going to good use

You should look into the RC-M chassis, mine's got the extended chassis and it looks and handles really nice. The 2.2" tires fit nicer as well, they don't look so packed in.

I don't know about the rcm chassis, I'm content without the best. I'm happy with what I have.

CLEAN WIRING ATTEMP #2

Ian, yes, I know, my rx wirs suck... I think I have the locations of everything good though. Only thing is I'll need to run with the body on with my esc location.

I'll try to make an esc mount that sits it lower then the level of the ground if the car flipped over.

Of course, running with a body means I'll have to find a way to mount the front of the body...

Also I got the battery tray on there. You'll see better pics later. It's a little rough too, Ian, I know.

I've noticed that whenever I try to do a clean build it always turns out to be a total disaster (I did a NICE E-Revo conversion that ended up costing me over $2,000 before I tossed it). The ones that are tossed together and simply work are always the ones that withstand my punishment longer than 10 minutes. Just get it working and bash it, it's not a shelf queen is it?
