It was funny watching your son jumping out of the way!

The CRT looks good. I'll bet it runs plenty fast when on a track.

I put 3,000 wt oil in the CD and it seems just right. Doesn't diff out and yet doesn't wheelie (kinda wants to, but doesn't).

However, about 15 minutes into playing, the pinion grub screw fell out so I guess I have to use a little more locktite. :)

The motor and ESC were kinda warm for my liking though. But maybe it was because the pinion was too loose and the motor was spinning too fast relatively unloaded. It's GOTTA be something like that because the Jato runs cool as a cucumber and it's geared higher.

Overall, I'm pretty happy with the results and it'll be fun to play with this summer. :)














So brian are you saying you have a screw loose ?:eek: .

Procharged: Like I said, he knows how I drive. :) He's probably still a little gun shy from when I literally knocked him off his feet when I was tooling around with the Hyper 8. That'll teach him for standing... well... pretty much anywhere. :) Yeah, it's plenty fast for the track I plan to race at. I figure ~30-35mph.

rchippie: Like you need me to tell you that? I thought it was obvious. :)

rchippie 04.17.2007 10:07 PM

Brian your truck looks pretty fast. I have a 13t hardended pinion if your interested.

ClodMaxx 04.17.2007 10:18 PM

sweet truck, brian... looks so nimble and quick!

you shouldn't feel bad about your son jumping out of the way - you're sharpening his reflexes! :026:

BrianG 04.17.2007 10:41 PM

rchippie: I might just take you up on that. I want to see how it runs on a track again where the pinion isn't loose first to see if the motor/ESC still gets hot.

Clod: LOL, I'll tell him that- I'm sure he'll appreciate it. :) Besides, It's not like I was anywhere close and when he did jump, it was a tad delayed so he needs his reflexes sharpened. :)

Cool video. Nice drive way for drifting. :027: Have fun with it!!

I thought it was pretty funny how your kid jumped right after the car passed him, lol. You've got to keep him working on those reflexes. :005:

BrianG 04.17.2007 10:55 PM

Yeah, but those rocks hurt! One of the kids was at the other end of the driveway and got hit by a small rock from the Hyper 8. I need to sweep it clean of all rocks I guess, but then turns into a mudpit in the spring. Yuk.

Looks awesome Brian. Mine arrived today. I'm going to shoot Mike an E-Mail to order me my motor right after this post. I also made my own thread. Preliminary measurements show that the motor will fit with the stock brakes (wohoo!).

I'm already loving this little thing. I just need to get some stuff sold to get some funds for this thing. (My 18T, HV4.5 motor, and some other stuff).

BrianG 04.19.2007 10:08 AM

I think you'll be happy with it! I can't drive worth a crap and I think it's a blast! :)

:005: I can't drive either but this truck makes up for a lot of that! It's so forgiving. I was able to get some video at my track that I just uploaded. I'll post a link as soon as Youtube processes it. Then you can all see how poorly I drive:D

Good News For Me
 
I just bought a CRT.5 it should be here thursday. I'm going to run it nitro i will be using a TRX 2.5. My friend orderd two he owns a hobby shop, so i got it at a real good price. I also ordered the ofna starter box for mini's .

gixxer 04.19.2007 05:38 PM

Just ordered mine too. Mine will probably take a little longer then your to get running though because I will be converting it to brushless.

BrianG 04.19.2007 05:41 PM

Boy, it seems like these are going to be popular little trucks! They just came out and there are already three conversions on this forum alone! If we keep this up, Mike will have to have two Monster Bashes; one ofr just CRT.5's, and another for everything else. :)

I ran my CRT around the house a bit more and am not very happy with the ESC and motor temps.

What's weird is that it is geared lower, is lighter, and the tires are smaller than the Jato, but the Jato stays cool despite the fact the Jato goes MUCH faster. CRT Mesh is just right - not too loose and not too tight. Everything spins smooth as silk so it's not the drivetrain. I want to keep this thing in the mid 30's speed-wise, so more voltage is out. I'm already using the MM 4600 motor.

I'm thinking that the motor isn't being loaded enough because the truck is too light and geared low. Things heat up just like if I were to run with the truck off the ground (unloaded). Everything I can think of to increase the motor load makes it run faster. Setting the radio EPA would solve the speed issue, but not the underlying problem.

So, was thinking of trying a Feigao 380c/9 (kv=4386). This would make the motor loaded perfectly I think. Any thoughts?
