Love it!! Because muggy spares are non existent now, what parts can be swapped over from the lst family

The Muggy uses LST/LST2 parts everywhere. Bulkheads, driveshafts, everything. The only difference (I think) was the center diff & mount, and the chassis.

The steering bellcrank and the corresponding top plate for it are Muggy specific also. The diff cups and spider gears are all LST including the center, but obviously the spur is Muggy/8ight and the front and rear diffs are 4.09:1 ratio instead of the LST's 3.31:1 ratio. Muggy diff gears are getting hard to find as they were discontinued and so were the Sportwerks Mayhem ST gear which were the same ratio. Shocks are have shorter bodies and shafts, shorter towers too, but the rest of the suspension is all LST.

To answer your motor mount and battery tray question from the other thread, RC-Monster has a mount for the Muggy. The 1717 will fit but there won't be much room to spare between the motor and chassis. Since the stock Muggy chassis flexes a lot I'd space the center diff up a little to keep the motor and chassis from contacting each other. RC-Monster has universal trays you drill, they may have a Muggy specific tray though. I've seen lots of Muggys with the Losi 8ight tray on them, I'm not sure of new holes need to be drilled though.

the only problem is that there seems to be only one provider of the motor mount..and that is RCM..postage to australia is more than what the mount is worth, which is just silly
hoping someone out there knows of another mount that may work..maybe some losi mount? i like the losi 8 E conversion mount as it has a angled slot for the motor to slide into. but dont know if it would work on the muggy

The bolt pattern is different. The 8ight uses a wider bolt spacing than the Muggy so it may be possible to drill the Muggy chassis for the 8ight motor/diff mount.

Also I edited my previous post as I forgot to mention the Muggy uses different ratio diffs compared to the LST. These gears are getting harder to find as they have. Een discontinued for awhile now.

With the diff gears being so rare, one could easily use the lst crown and pinion..should work? The diff internals can also be lst

LRP Spec 3 with a JP-2!... That was FUN...

Wrong forum perhaps? We are talking about brushless conversions here

Herrsavage

Oh, are we?...

We are talking brushless but the thread title does include Nitro.

The Muggy uses LST diff cups and spider gears on all the diffs, and they're the same as what's used on the 8ight. Ring and pinion are Muggy specific, spur gear is Muggy/8ight. That said it may be possible to adapt the 8ight-t FRONT ring and pinion to the Muggy, you might want to do this because the 8ight-t is 4.11:1 and it will help with gearing. I have to double check but with a 50t spur (from the 8ight) the smallest pinion you can use is either a 12t or a 14t, any smaller and the motor will hit the center diff outdrive.

The 1717 on 6s with 14/50, LST diffs and Truggy tires will be 50mph with no ballooning. Swap on LST size tires and you'll be at 60mph, again assuming no tire ballooning which there definitely will be at these speeds unless you tape the tires. If 12t can fit you'll be at 42mph with Truggy tires and 51mph with LST tires, again no ballooning factored in.

I'll try to double check tonight how small of a pinion can be used. I actually worked this all out over a year ago because I was also considering a Muggy but was also worried about the ring and pinion availability.

My Muggy wears Trencher's, and is running the stock 46T spur on an 11T (Novak X-Tra Hard) Pinion, 2000kv motor for a FDR of 1.27:1. On 5S, the motor typically comes off around 150-160f if I've been hammering the throttle.

Didn't know the Mug used different diffs. If you ran 9/50 or 9/46, you'd get 1.18/1.28:1 on LST diffs. I've got a 9T Mod1 5mm bore Novak pinion that I know works fine in an E-Muggy, as I ran it on mine before moving up in teeth to the 11T.

So is the rc monster mount the only one that's available for this truck?? Postage is the same price as the mount..what about battery tray and esc plate..do you guys use the 8ight-e one?

The Muggy's 4.09:1 diff ratio is the only reason you can run the 2000kv on 5s with those big tires without a larger spur and you're already using a fairly small pinion. Remember the early days of truggies when they were running 3.31:1 ratio buggy diffs (same as LST) with huge 65t spurs? You can run 9/46 on your Muggy because you have a 40-42mm diameter motor. I just double checked my 1717 with a 50t spur and with a 12t pinion the motor hits the diff outdrive before the gears mesh, I doubt grinding the motor fins away would help. A 13t pinion has a mm or 2 of clearance between the motor and diff outdrive. I don't have a 46t spur check with.

No offense, but you are confusing rollout with final drive ratio (FDR). Rollout is dependent on FDR and tire size. FDR has nothing to do with tire size. Your Muggy has a diff ratio of 4.09:1 and the 11/46 creates a 4.18:1 ratio. Combining the two equals a FDR of 17.1:1. Quoting rollout instead of FDR can be a bit more useful but we don't know what size tires he wants to run and rollout is only a guide for initial setup. Just saying.

Ah, yep. 4074-Canned motor, that'll do it. I forgot the 1717 was so enormous.

No worries, man. I was indeed getting that mixed up. I was thinking rollout, not FDR.
