is this going to fit the Wraith?



Ordered some thinking they were all the same?


Cheers

There are threads on those shocks, probably better luck there than in the motor thread.

K Harley cheers

Anyways good news, my rig is on its way

Everything paid for
All other stuff selling to fund this sold

;)

Im trying to decide between Tekin ESC's, RX8 and a RS Pro. Any advice on which one.

The R8 has more power handling ability. It depends on what motor you plan on.

[MaxxPain]

There both close to the same price, so I figured just keep my options open. Might use it in a different vehicle later on.

If you have room and don't mind the little extra pop for the R8. It's perfect if you plan on the Pro4 motor.

I'm still learning about crawling but I can comment with certainty about the Tekin stuff. The RX8 is a very robust ESC but honestly for this application the MambaMax Pro is better suited and much cheaper. Also the Castle permits/has the capability of programing with a pocket sized card(No PC required)
Between the RS/Pro and the RX8, the RSP will efficently run the pro4 3300kv on 3s in a crawler/Wraith application with no problem and the RX8 is serious durability insurance but with that comes excessive weight and footprint. Both have very capable internal BEC's where as the MMP is prone to be a little weak.

Was thinking, I have a Novak 4.5T 550 Ballistic on 2s I want to try. I tried this motor in an E-Maxx with a MMP on 2s and the truck did close to 20mph. Great power. So curious to see what it would be like. But use an RX8.

Suggestion for gearing? I am putting in a Tekin 35T, and using the stock ESC, using only 2S lipos. Only going to use it for trail running, would like to be able to crawl slowly, yet have enough top end for a brisk walking pace. Is that possible with this combo? I have upgraded the servo and put beadlocks on-8oz in the fronts and 4oz in the rears.
Thanks

Try just bumping up to a 84 spur, stock pinion.

That is a ton of weight to be adding. Your drive train and motor aren't going to like it very much. Mine has the electronics moved to the rear battery up front and 3oz per wheel up front. I couldn't be happier with the way it crawls and runs the trails. I have actually been thinking about dropping a little weight. From my experience there is a limit to how much weight you add to much can actually hurt you when trying to climb. As for the motor I run a HH 35t with a 84t spur and right now a 19t pinion on 3s and it is almost as fast as the stock motor and on 2s it is a little more than a fast walk. Hope this helps.

I will be trying out my 18.5 novak brushless in my wraith, im using 32p gears and need to know what size's to start out with, any help? thanks

The stock ratio is 4:1, so start around there or go lower. I run 60/15, and it's a tight fit.

I have yet to assemble the first screw in my Wraith and I'm trying to figure out the gearing, I plan to run a 3100kv Sensored motor on 2s and with the 32P spur and pinion. Heres what I'm looking at, Not sure if this estimated top end speed to much or not enough ??

Differential Ratio: 2.923076923076923

Motor Coil Resistance: 0
Spur/Pinion Ratio: 2.32 : 1
Total Ratio: 17.632 : 1
Tire Circumference (inches): 16.34 inches (414.94 mm)
Rollout: 0.93:1
Total Motor Speed: 22940 RPM
Vehicle Speed: 20.13 mph (32.33 km/h)
Effective KV Value: 3100
KT constant: 0.44 oz-in/A
Motor Torque: Amperage not specified...
Final Torque: Amperage not specified...
Final Power: Amperage not specified...

58/25 is way too high of a gear ratio IMO.

I'm new to crawling so 20mph was "crawling" for me.

What kind of speeds should I be looking for, gonna need some wheel spin and speed for hill climbing ?

Rarely does anyone in crawling relate to things in actual MPH. Plugging things into a calculator like that is a rare practice. A 3100 KV motor is going to be fast so I would gear down. I would go in the 60/15 or 60/12 range to start.

I understand where your coming from, I'm used to 6s and 8s beasts so 20mph seems right in the "ball park" LOL

I want a little speed from this thing because I plan to bash and climb/crawl. I'll heed your advice and start lower with 62/22 BC thats what I have in hand right now.

Thanks H.

You better heed a little more my way because that combo isn't going to fit without modifying the motor plate. You need to drop that pinion way down.

[BONDONUTZ]

Since "you've ben there done that" enlighten me on what is the maximum gearing options are without motor plate mods plz.
