I had to do a little thinking outside the box on this one. I ended up finding some gas strut rod ends that were a near perfect fit. I just had to find a bushing to fill in the eyelet gap.

I have only busted 3 of the plastic ends but these are a serious piece of steel beef, the ultimate overkill. Th base of the steel end is M6 while the eyelet is M8. So I use a 5x7x8 bushing & a small strip of 3m double-sided tape to fill the gap.

. . . & yeah, those links are HUGE 💪
One word... DAMN 👍🏻👍🏻
 
BTW, if you want to know what's in the link, I found a grade 8.8 carbon steel 120mm M8 bolt, cut down to 110mm. Added a 10x8mm CF tube to clean it up.

It's hard to pass up a good deal . . . so I took a chance with these gearboxes & they're spot on perfect. They are thin on the anodizing unlike the GPM variant. Vitavon finally has their box out too. Plus these beefy 8mm links are serious overkill.

I also found right & left hand helm ends that fit the EXB rear link great, now lets see which one holds up better.

These wing mounts are taking a serious beating too & are wearing in well.

I finally conjured up a way to reinforce the front turnbuckles. They always bend or break at the thread so this should give them a chance at surviving a bash or two.

That is a M6 bolt attaching it to the steering block so it should be all good there too. I was going to try a 6x8mm steel tube but I had the CF tube on hand.
 
The huge 50mm fan fits the ma5 like a glove.


Definite game changers ;)

I'm never gonna get tired of unbending CVDs . . .

 
What are the advantages of swapping out to Mod 1.5 gearing? Asking as a newb because if it’s better, I’d like to try it. And...what did you use as the spur gear? Part number if you have it...

cheers,

This is one of those basic unknowns in the RC world, but being an engineering gearhead . . . Mod 1.5 has larger teeth so it can handle more power, torque, & have a greater energy transfer per rotation - meaning it's more efficient, but these electromagnetics are ULTRA-efficient from the get-go :rolleyes: Simply put, larger teeth are always better - & lets you do crazy stuff like this w/o overloading the motor:

. . . 19t spur, 23t pinion

They are both HR mod 1.5 pinions. As for trying it, this is something I always wanted to do. It won't work with the plastic gearbox since I had to eliminate the motor mount bearing. I also had to mill the bearing hole to fit the base of the 19t pinion. I had to completely cut it out on the M2C mount to fit the 23t pinion.
 
I know the folks here are fairly hard on the brand of upgrades they put on their rigs but I could care less. All I want is for the upgrade to BE an UPGRADE, meaning I want it to FIT & last longer than the stock part. So I'm trying the cheapo Integy stuff & I'm sold so far. I broke the stock rear towers on both V1 K8S & O8S. So I went with GPM & they work great but they are super heavy. I just got an Integy tower in & it's a very high quality billet part compared to GPM's casted stuff. Plus it weighs 70g less than the GPM. I got the rear hubs too. I have the HR hubs but cracked one the CF pieces in half (fixed with superglue). I'll replace the CF mess with aluminum one day if I don't replace it with an Integy hub. But I have to say that I haven't busted a plastic hub yet. The Integy hubs can't fit a 3rd bearing like the HR & Vitavon. I drilled out both tower & hubs to 6mm to fit my links.

I think I found Juggernaut's limit. The Integy stuff fit great & the double rear links took an awesome beating & are STILL STRAIGHT :love: (y) 💪 But the crazy 19/23 gearing proved too much for the batteries. The ESC & motor wasn't breaking a sweat @ 110°F & 138°F respectively when the truck reached LVC. But the batteries hit 146°F, WAY hotter than any battery temp I ever took. Plus the truck seemed to lose a bit of power at full throttle. So I'm going back to 23/23.

I got tired of the pillow ball mess & the teflon tape wore out again so I dumped the plastic junk for some cheap Integy junk. Plus, I got rid of most of the heavy GPM junk. Now all I need are some decent bulkheads out of these guys & M2C to come through on the CVDs. I'm still not touching the Vitavon stuff since my luck with customs has been nonexistent this year.
