Anyone have the hot racing hex's +5mm extensions? If so how do you capture the hex pin now that it is no longer inside the wheel ?

I got them...there's a little grub screw inside the axles that holds the pins from falling out..

I watched the French dudes video, if I understand right he said get the shock collars from the hyper ss truggy for more suspension freedom, for lack of better words, and to buy what rod ends to increase the travel? thats huge...I'm sure you guys have this all on lock by now, I'm a newb to arrma, not the hobby...he said he got a extra 20mm's thats alot..so I'm assuming the rod ends are strong, and longer? didn't say how to adjust, like bottom them out, make each rod X length, any direction would be helpful....I'm also searching for that chassis extension from Custom Hobbies? and the axels etc...than fit the X-Maxx body on, that looks insane...thanks in advance!

For sure you will want the Hobao spring retainers (Hobao Part #90049 the retainers are part of this set). I made my Big Rock taller, by modding the skid plate to allow for more suspension travel and just unscrewed the rod ends a few mm each. Unfortunately, I don't have a great picture of my rod ends, but if you check out Update 4 of my build log I have some picture that show much more clearance I got with the Hobao spring retainers.

So far I haven't made to many changes, but have had to take the truck almost completely apart and put it back together again. I am still very happy with it, but have had my center diff servo, one lower read suspension arm, and one upper front suspension arm all break. The servo and lower rear suspension arm were both replaced by Arrma under warranty at no cost. I didn't put in a ticket for the front arm because I was already ordering some other parts and wanted to get the replacement quicker. The warranty parts took 2-3 weeks to be delivered. I have only run 6 sets of batteries through this truck and have not been jumping it at all yet. What I have done so far is to add the Arrma wheelie bar, personally I think this one looks better than the T-Bone Racing wheelie bar. Either way a wheelie bar is extremely important on this truck. I have also added the optional dirt guard set and replace the stock springs with the larger optional 75mm springs. While the truck was apart I also modified the front and rear skid plates to allow for more suspension travel. Unfortunately, I don't have a before picture to really show the difference in the stance, but it is pretty obvious that my truck sits higher after installing the longer springs and modifying the skid plates. Here are a couple of picture of the truck and a parts list of what I have added.

Wheelie Bar: AR320255
Dirt Guards: AR330414
75mm Springs: AR330417

QUESTION, DID YOU BREAK THOSE ARMS BEFORE OR AFTER YOU ADDED THE EXTRA SUSPENSION TRAVEL? THANKS

I have only broken 1 A-arm and I broke it in the first 20 minutes of owning my truck. I had been out of the RC hobby for many years and decided to get back into it. I did some research, watch some youTube, and found the Arrma Nero. When I was actually ready to buy something, Arrma had just released the Big Rock and I am I am BIG truck guy. I like my trucks lifted with crazy power so I went for it and bought the Big Rock and a pair of 3S packs not really knowing just how powerful this truck would be. On my first run stock out of the box within 10-20 minutes I cartwheeled it a good 30-40 feet and snapped one of the front lower A arms. Since then I have not actually run the truck that hard, I know it capable of much more, but I am have fun getting back into the hobby so that's all that matters to me. Honestly I have had just as much fun working on this truck as I have had driving it. I know not everyone want to spend time working on their RC's, but for me it's just as much fun building, fixing, and customizing this truck as it is to drive it.

@Tblazin So to answer your question, I broke the A-arm before I lifted my truck, but I also have probably not driven it quite as hard since I lifted it. However, I am not the only one who has lifted their Big Rock and I know for sure that some of the other people who have done similar work have run their trucks much harder than I have run mine.
