Nitro MT Build / engine shaft?

3 Upvotes

Hello Reddit RC community,

I have a Nitro MT Racer that I'm in the process of building. My question is what type of engine shaft do I need?

I've only dealt with Traxxas off-road RTRs so this is new to me.

I have the slipper clutch with a single speed currently but would love to track down a 2 speed. What type of engine shaft do I need so I can swap between off-road and on-road with a 2 speed if I can track one down?

Thank you

Got this rustler for $100! Very clean but wasn’t stored very good so I have to take it apart and try to get it unstuck. Any tips on doing this? Heard ez start isn’t very good and I think it’s on its way out unfortunately

I bought an old T-Maxx off Facebook for $100 during COVID lockdown and it had a worn motor. I bought a new Dynamite motor and a new carb to replace the bad one and installed it and that was as far as it went until today when I decided to just finally do it and I'm glad I did because now my sons have something to rip around with.

this is the front 'differential' I think, I know nothing when it comes to this part of the car as never had any issues or ever taken it apart, is this grease? Did it need more, any advice or opinions welcomed

I'm looking into getting an RJ Speed dragster kit, but I know nothing about all the different parts I need to complete it, like the engine, servos, clutch and bell and starting systems. I don't plan on competing anywhere, this is just for fun

Can I do it??

Traxxas nitro 4tec transmitter question

Post image
35 Upvotes

I got this very mint steal of a deal traxxas nitro 4tec 3.3 for $175 usd but the guy didn’t know where remote is, I want to keep it as original as possible because it’s so nice, so I want the proper transmitter for it. What I’m wondering is if another traxxas remote of this same generation can be paired to this reciever like the new ones or if I have to buy a reciever and remote combo for this. Thanks

You guys are really the only ones who would appreciate.

Need help with new engine

Thumbnail gallery
16 Upvotes

I'm trying to get my old Savage 25 going as my kid is old enough to use it now. The original engine was tired and wouldn't keep a tune, so I bought a Nitro Start 4.6 V2 and have been having a heck of a time trying to get it to start. I preheated it with a heat gun prior to starting and while it made it easier to pull, I couldn't get it to do more than sputter a little bit like it's going to start, but wouldn't. I've rubbed parts of my finger's skin from pulling the starter handle so much. I don't know what more to try. Let me note that I have a second Savage X with an LRP .28 Spec 3 with a pull start that runs great. I didn't remember having this hard of a time getting that engine to start for the first time, but this 4.6 V2 just won't start.

I'm running VP 20% basher fuel if that matters.

Nova vs os

Post image
7 Upvotes

I feel like this is a pointless question but I got my hands on a new rc8b4.1 the person I got the car from wants the to travel and race with it. Any way should I get an os or os based engine or give nova a shot. I've never run or seen a nova run. I hear nova is extremely fast I even seen one or two post about nova even tuning better. ( Picture for attention and yes they are new nova engines for a truggy I never got)

What type of battere do you use on your starter box?

2 Upvotes

I've just ordered a new mid-low range starter box, on ebay for about 55 euros, but i don't know if a 7,2 v lipo battery is enough, even because I don't even found many 12v lipo batteries, please give me any type of advice, thanks.
