Honestly WF idkDoes that have the same setup as the X-Maxx? Not familiar with that kit, but www.wforccustoms.com has 1.5 gearsets for the X-Maxx. You might check there.
At first I read…WTF…Honestly WF idk
My bad bro lolAt first I read…WTF…
No sweat tho, we’re good here
or smaller pinion, either way. could do both if you needed to but if top speed is what your after Id start with the tallest gearing possible.By tune down you mean make the spur bigger in tooth size?
Idk what you mean by tallest gearing Grey. This is my first speed build. Not trying to chase or break anyones pb just set my own in the high 80s to low 90sor smaller pinion, either way. could do both if you needed to but if top speed is what your after Id start with the tallest gearing possible.
Thank you grey. Yes its alot to take in but i like going fast so i wanna learn i just dont want to set my truck and or esc on fire? What causes fires like the ones people post on youtube I've asked but no one has ever really answered the question directlyThe smallest spur and the biggest pinion possible would be the tallest gearing possible. If you're not going for maximum possible speed then maybe start with 1:2 gearing and tune from there. Lemme know if you have anymore questions. It can be alot to take in initially
Drawing more amperage than the ESC and/or battery can handle for too long. Gotta keep an eye on those tempsThank you grey.

I'm putting in a max 4 and probably a castle 1650kv motor so hopefully that combo will be minimal on the amps. I'm gonna use better batteries than the hoovo i got like gensacearespammers or cnhlDrawing more amperage than the ESC and/or battery can handle for too long. Gotta keep an eye on those temps
Max4 should be good but the 1650kV is a 1717 series motor which are designed for 1:8 and 1:7 scale rigs. You need to look in to something for 1/5 scale.I'm putting in a max 4 and probably a castle 1650kv motor so hopefully that combo will be minimal on the amps.

Wouldn't a 1440kv motor be slower than the 1650kv motor and also have more torque? Where would a person even look for a tp motor? And couldnt you run a castle 2028 series on 8s? Whys it just have to be 10s?Max4 should be good but the 1650kV is a 1717 series motor which are designed for 1:8 and 1:7 scale rigs. You need to look in to something for 1/5 scale.
My first choice would be a TP Power 5680 1440kV motor on 8S
Second choice would be a Castle 2028 series 1100kV motor on 10S.
Id look at CNHL or Liperior Pro lipos myself. Gens arent as good and more expensive.
This is the TP Power motor.

The 1650kV as mentioned earlier is a 8th/7th scale motor with a 46mm diameter can size.Wouldn't a 1440kv motor be slower than the 1650kv motor and also have more torque?

You absolutely could run the 2028 on 8S but will be slower than the 1440. Even if you ran the 2028 on 10S it still produces about 2000 less max RPM than the 1440kV. On 8S the 1100kV will have about 10,000 RPM less than the 1440kV on 8S.And couldnt you run a castle 2028 series on 8s? Whys it just have to be 10s?
Hey buddy thank you for the tips i really appreciate you my friend. I havent even ran the xrt on stock yet its been too wet and cold where I'm at and i dont want to risk breaking anything yet. I've just been doing small slow upgrades (wing mount, battery trays so i can remove the battery hold downs, replacing the front and rear bulkheads, upgrading the drive train to m2c, and taking notes from people here and on Facebook about what to get so i can outfit the xrt right and hopefully not worry about starting any esc or lipo fires (I'm still not sure why some people on youtube even video their rigs going up in smoke to begin with, and i still dont fully understand what causes a lipo fire but I've heard its from mostly castle escs which I'm not using although speed guys think those are the ultimate go to. As far as gps i have a sky rc gsm 020. And i totally get you on when you said speed comes in small numbers.Hey Nutts. Sounds like fun. XRT is fast out of the box. 50+mph according to the TRX XRT site. What speeds have you gotten out of it so far? What are you using to record speed?
Reading the specs, XRT comes with 20/50 pinion/spur gearing for a ratio of 2.5:1. Option gearing for 60+mph TRX lists as 23/46 for a "higher, taller" ratio of 2:1. Also of note is that the TRX skill level recommendation goes from a Level 5 to a Level 6 when using the 2:1 ratio. That seems to indicate there will be some chassis tuning coming into play at the increased speed.
Knowing that, were it my truck, that is the two baseline ratios I would begin with. Find a good, safe wide spot without obstructions for some runs. Get used to the feel of the truck in speed runs. Then begin the process of incremental changes. Speed comes slowly and in plateaus to do it safely and make it easy on the wallet.
Hope this helps. Good luck. XRT is a massive package. 'AC'
Glad I'm able to help. If you get to the point where you want to go beyond 8S, TPPower is a good place to look for a motor that will be good for it. (They even make custom motors) The 1440kV is limited to 8S although it will produce higher RPMs than the Castle 1100kV on 10S or the Castle 800kV on 12S. If you're not already familiar, you can calculate the max RPM by multiplying the battery voltage by the kV rating. At least with no load on the motor anyway. Lower RPMs doesn't necessarily mean slower though, gearing can make up for some of that and there are theoretical speed calculators online that you can plug in all of your gearing info etc to find out what is theoretically faster. A lower kV motor will be able to handle taller gearing (closer to 1:1) better than a higher kV motor.Grey you are absolutely awesome my friend. Thank you so much for explaining it the way you did it really helped me understand it. And i greatly appreciate that. I do plan on going beyond 8s just not right out of the gate. And now that you explained it to me i am def gonna be getting the tp 1440kv along with the max 4. I prefer the max 4 simply because I like to future proof things for as long as possible if that makes sense. Also someone told me something last night that i did not know and it didnt make sense to me at all but it came from one of the top speed guys i know on Facebook and youtube. He said the motor gearing isnt the only gearing that needs changed, that the differential gears need changed too or something to that effect. I was under the impression that the only gears i needed to adjust were the spur and pinion of the motor gears? I also dont even know what tooth to start out on either as no one has ever given me a straight concise answer. I was told that it depends on the diameter of the wheels i will be using for runs which ill be using gone bananas racing skins and they are between 6.5 and 7 inches in diameter. Thank you for all your help my friend. I'm definitely learning a lot from you
