Harley's Axial Wraith Build - Jimmy's 4x4 Ultra 4 KOH Style

[FRENCHBLUE72]

Hey Fellas! New guy on the rock crawler circuit. I purchased a Wraith and for my son a scx 10....I have in my box o parts two JR8711 servos that I received from who knows where.
JR DS8711 Ultra Torque Servo (JRPS8711)

At the bottom it says for airplane use only. Anyone of you knowlegable folks tell me why these servos are for airplanes only?...Can I use them in th wraith and scx-10??

Also when installing a ubec...do I just plug it in to receiver or do I have to cut a one wire of the three from esc to reciever?

Thanks for help and thanks for a great thread! Very helpful!



I think I found the answer on anther thread.....

The only thing I can think of is the gearset, despite being metal, maybe isn't as durable as surface-specific servos?
That was always my understanding of it. The gearset not being able to withstand the shockloads a land vehicle would see in say the steering system. Aircraft servos see loads that are more steady (or ramp up more slowly) instead of shock loads (like hitting a rock while driving). I'd imagine the gearsets for land based vehicles are wider to better deal with shock loads.

This would be better in the newbie section but welcome to the board... Harley I have a ton of pics in the ttc picture thread of your truck from this weekend... Thanks for showin that you are just like the rest of us when shit breaks you gotta fix it.. Nice job this weekend ...

Im sorry I was being nice and directing you to the forum that would best help you with this question? I dont see how you are contributing to this thread as this question is totally out in left field? This is a build thread last time I checked?

 

[Kaw1000]

Thanks for being nice. It is good to see the thread police are out in force. Do you know the answers to my question...if so...why not answer it instead of telling me where to post it?
Imo this has everything to do about "The Build" A servo question and a bec question is not part of a build? Thanks for taking the time to comment on where to put the questions
but forgetting to answer my questions.

Well last weekends trip was amazing. I had an absolute blast.

I did a recap article that is up on the home page for anyone who wants to hear more about the event as a whole. I also posted over 20 videos of the different classes and events as well as interviews with each TTC Competitor.

Now onto some of the pictures that are starting to roll in from the TTC :twisted:

These shots are from Scale4x4Aliance (Pointman).

Truck Pull - Full pull both times. The last one was a little more eventful :lmao:

 

[Harley]

A couple more from Pointman

Mud Pit - Fried my BEC about 3/4 way through and shut down the system.

Catching some air on the obstacle course! I finished this course with seconds to spare. I was the first one to complete it.

Last couple shots from Pointman.

This was on the frame twister. Finished, just with a slow time :roll:

Dirty girl....

 

[Harley]

These shots came from Frenchblue.

Frame twister I believe.

Awesome shots!

That's a great looking rig. Do you run tubes in those VP axle housings, or are they plenty strong as is?

No need for any extra support in them. The wall thickness on them is very high. I have a picture in this thread somewhere (good luck finding it) that shows one cut open.

Love this pic....might have to print one out for the shop wall.

You ready to build that sled now??

Nice! I have beef tubes in the axles now, but those VP housings are calling my name!

So now that I'm obsessed with TTC but still love the KOH style I think I'm going to move to a new chassis setup.

I want a competitive TTC rig as well as some cool KOH style. The rig that came to mind was Campbell Ent 2012 KOH and TTC rig.

I threw some lines together today at work. Might go with something along these lines.

Do it up Harley. It was cool meeting you and great job in TTC! I am also hooked!

Full tube or frame railed?

I'm leaning towards an SCX base now. I want a narrower skid plate mostly. The Wraith skid is awesome for ease of building but it's just really wide. We shall see. I have to see how busy Jerry is and if he wants to work with tube.
