My Savage rebuild: The LST killer
This is my Savage, named the LST killer because it does just that. I built this truck from the ground up to withstand the most extreme bashing.
Power supply:
Picco 28
Ofna 086 pipe
Ofna short buggy header
Double header retaining springs
Motor Saver air filter
Ofna 125cc fuel tank
Dynamite Max-life clutch shoes
Mugen 1.0mm clutch springs
Mugen clutch nut
Teflon sealed clutch bearings
HPI 17t clutch bell
Ofna clutch shims
Chassis/Suspension:
IRC 4mm thick, 1.25 inch extended LCG TVPs
IRC one piece 6082-T6 engine plate
IRC 6082-T6 center skid plate
Custom 13mm diameter 6061-T6 front chassis brace
HPI 6061-T6 bulkhead plate braces
Savage X easy access transmission case
Savage X radio box
Composite easy access bulkheads (Savage X) (Stronger old style w/steel pins)
6061-T6 bulkhead pin retainers
Savage X skid plates and shock towers
Original 21/25 bumpers and braces
Original 21/25 upper and lower arms
Lunsford 6Al 4V Titanium hinge pins and turnbuckles
316 stainless steel turnbuckle washers
Custom 6.4mm 6061-T6 rear turnbuckle/bulkhead brace
IRC 7075-T6 upper and lower hinge pin braces
HPI composite shocks with 30wt oil
FullforceRC triple rate shock springs
Custom 3.2mm 6061-T6 rear knuckle/carrier braces
HPI Nylon roll bar and engine protector with extensive bracing
Custom 6.4mm 6061-T6 roll cage extending bracket
Ofna linkage setup
Class 12.9 alloy steel fasteners
Drivetrain:
HD 2 speed transmission (Now standard on Savage models)
Hot Bodies steel brake hub
HPI single fibreglass disk brake
IRC UHD front and rear center dogbones.
CEN GST7.7 differentials and pinion gears
IRC UHD outboard dogbones
HPI 17mm buggy style axles and hexes
AvidRC metal shielded bearings in the transmission and inner pinion gear bearings
AvidRC revolution bearings (metal/rubber seal hybrid) on the transmission output/input shafts and everywhere else.
Electronics:
POS HPI AM radio system
Hitec HS5645MG steering servo
Hitec HS525BB throttle servo
Venom 1200mah receiver pack
Hitec switch harness w/charge lead
Wheels/Tires:
Pro-line 13mm offset dish wheels
Pro-line molded foam inserts
Losi Zombie Maxx tires
Right side, showing the best TVPs on the market:
Left side:
The rear end, Showing the IRC dogbones, FFRC triple rate springs, Lunsford turnbuckles and hinge pins, modified bulkheads and IRC 7075-T6 braces + the custom 6061-T6 turnbuckle brace.
The front end.
Clear shot of the Zombie tires.
The Picco 28 and extensively braced X roll cage. The bracing adds an incredible amount of rigidity to the cage while maintaining its impact strength.
Clear view of the custom 6.3mm 6061-T6 roll cage extender.
Bottom of the truck.
The 3.2mm 6061-T6 left rear knuckle brace. This solves the turnbuckle mounting tab breakage issue.
An additional set of holes was drilled in the rear of the TVPs to allow for the mounting of an additional brace to attach the bulkhead plate to the TVPs for more strength. The front also has an additional brace, but the holes were already drilled in the TVPs from the factory.
Another picture of the rear turnbuckle brace. Should prevent the bulkhead tabs from ripping off in a hard crash.
A very bad quality picture of the front 6061-T6 TVP brace. It is mounted at the most stressed point of the chassis and should make failure 100% impossible.
As I do live in northern BC Canada, bashing videos will not be posted until spring when the snow melts.

RE: My Savage rebuild: The LST killer
I think you have a very thoughtful and well executed setup there. I think you have mitigated all of the Savage weaknesses with four exceptions.
1. I think your shocks are the weak link. I think you will still bend a shock shaft or break a shock before an LST does. I think a set of HPI Big Bores would overcome that.
2. LST's come with that FM Synthesized radio, so I see your radio setup as being a liability as a true LST killer. More chance of interference, possibility of crystal popping out of the receiver, etc....
3. Plastic spur gear? I see a lot of motor and a lot of extra weight on that truck. The spur is going to get hot and end up melting/stripping.
4. Finally, I don't see a throttle return spring or failsafe in your mods list, two critical basher items.

RE: My Savage rebuild: The LST killer
1. I do agree that the shocks are the weak link. I have tried a ton of setups without luck. They still hold up fairly well though. Currently looking into larger shafts for the stock bodies. I didn't have good experiences with LST shocks.
2. I also agree that the stock LST system is much better than the HPI TF-3, and yes I am looking at a Futaba 3PM 2.4ghz system, but the stock radio has worked well for years.
3. I have always run plastic spurs and have only had then fail when user error was to blame.
4. I generally run a throttle return spring, and as such there is no need for a failsafe.

Dales suggestions were valid, however they were just suggestions to help you become the "king" of bashing.... take what you want, leave the rest.

RE: My Savage rebuild: The LST killer
Also, I contend your 'showing the best TVPs on the market' statement... I am a BIG fan of Fast Lane Machine TVPs: 4.7mm (.187") thick for extreme abuse. That is about .7mm wider per TVP than Innovative RC TVPs.

RE: My Savage rebuild: The LST killer
ThunderbirdJunkie suggests ditching those triple rate springs for something a little more compliant.
Zero suspension compliance=broken parts. those effers are STIFF as HELL! At least stick with the stock black springs ITBJHO

He never said he had a STOCK Savage.... IIRC, the term was "Intelligently Modified"... which from the looks of it... means... "Mostly Modified".

The Innovative RC TVPs that I have now could probably take at least triple the load before bending, and there are no excessively thin areas that have the potential to crack...

Except for when there is interference... a trucker keys up his CB, or someone else is on your channel... not to mention a TRS only drops the engine to idle. If you're WOT and lose radio signal, it can still hit something at a high rate of speed. Failsafe will apply the brakes...but, hey.. it's your truck.... personally I'd throw in a cheap $30 Venom unit if I were you. My Revo has a TRS, however I also run a Venom failsafe... The LST2 doesn't have a strong TRS, so I've been just using the Venom failsafe on it until I can scrounge up enough $$ to buy one.

I have had 2 sets of FLM TVPs. Although they are thicker they are the WORST designed TVPs I have ever seen. No thought whatsoever as to how stress will effect the chassis. In other words, they just make them look cool and don't put material in the right areas. Case in point:

You do know that they have life time warranty - Just send them back and you will get brand new ones...

RE: My Savage rebuild: The LST killer
hi
some nice mods. i agree that the irc tvp are much stronger than the flm for serious bashing.
one easy mod to strengthen the stock shocks is put a little rubber inside the shock body so the shaft can not fully travel outside when the truck is in the air. that reduces the probability of bending shafts. you loose a little of suspension travel though.
bye

True, but in 4 years I have never encountered any issues, and with a Futaba 3PM 2.4ghz system coming around Christmas, there is no point in adding a failsafe now.
