That's a common issue when the motor takes a direct sudden hit on the back of the head. The head wants to go one direction, but the engine block is bolted down in the opposite direction. Only thing left to happen is for the force to split the two at the center point where the strongest part meets the weakest part, and that's usually level with where the engine bolts down to the chassis. This really had nothing to do with the design of the savage. This happens on all nitro engine that take hard lateral hits on the engine head.
The stock Savage TVP chassis aren't that hard to bend, in fact, it's very common. That hit didn't look too bad but the truck is on the heavy side and the mass of it at the particular spot the chassis hit the divider was the perfect storm unfortunately. One of my Savages has the FLM TVP chassis plates and I think a similar hit will also cause the chassis to bend as the FLM chassis TVP aren't super heavy duty, I think the innovativeRC chassis is the best one right now. I have several of those LRP .32 engines, some stock, some modded and the overall quality of those Chinese engines is decent at best. Mine had burrs on the sleeves just like countless others. Unfortunately, our options for big block engines are very limited especially since Novarossi is no more and O.S only cares about making .21 racing engines that are $400+.
I agree, the chassis of the savage is easy to bend, I was looking at the irc, they still have a +6mm in stock. As you say, the choices are limited, Nova, OS but also Picco no longer manufacture .28. The quality of LRPs is not good but at least they still sell for +28 and .32!
The engine didn't snap because the TVP chassis bent. It snapped because the engine took a direct lateral hit to the back of the engine head. This sudden hit forces the engine to move forward when transferring the force. The engine mount tries to resist this forced movement, which creates two movement forces and leads to the crack. The crank bell housing is thin aluminum mixed with thick portion of engine mounts. This creates a weak point and a strong point. When the engine takes a hit from the back and is pushed forward, the weakest link is this area between the engine mount tabs and bell crank. Everything below the mounting tabs are super secure. Everything above them are easy to snap. This is always where the engine cracks with a hit like this or if you land on the back of the head. This is an issue with most nitro engines. The fact that the chassis bent is a good thing for the engine or it would have been damaged even worse. The engine would have been better off if the chassis were made out of noodles.
Wow that seemed like a small hit but that was massive damage. Get yourself some innovative RC chassis and engine plate. They are 4mm thick. They are a bit heavy and not cheap, but I think it's well worth it!
IRc parts are tough, they are worth the price, i might buy a chassis. How long do you think it will take to burn 9 gallons of fuel and sell me your lrp crankcase? 🤔 2 weeks should be enough 😁
@@TastyBRC lol I haven't run mine in a while. I got a nova carb for it but I sanded it down some but it was not quite enough. Not touched it since. I have been trying to drive the TVR rather than rc cars in my spare time before the winter comes. I will look for the crankcase part for you though! If I see it I can buy it for you and send it over.
@@TastyBRC thats why I dont like the 2 piece engine mount on the savage, someone should make a 1 piece aluminum block that joins the two tvp plates and have the engine bolt to that, that would place the stress on the block of aluminum instead of the engine’s crankcase.
Wow, that’s a big bummer.. I’m puzzled how that crash on the curb caused so much damage? Did the bent chassis cause the throttle servo to fully extend causing the full throttle?
Hard to believe that such a small curb caused so much damage... the carb wasn't completely open, at the time I didn't understand why it went full throttle (the servo extended to brake position). It was certainly due to an air intake by the crack of the engine block
@@TastyBRC ah of course I should have thought! That was a big crack so that thing went into extreme lean mode sucking in all that air. The questionable quality of the lrp engines didn’t help either. I have a .32 and it’s one of my least favorites tbh. Just like you showed in the video my sleeve is flat out the worst I have ever seen from any other nitro engine
@@jeremiahrobles4038 It's true that I said it was the worst cuts I've ever seen but I also have a lrp.32, that one is much worse. The LRP quality is a shame but at least they still make .28 and .32's..Be sure that somehow the .28 will run again!!
@@TastyBRC it's not just a pullstart issue. The block at the back hits the chassis. Might just try to install it in my kyosho neo st should fit I would assume
Ouch, looks like the heatsink fins got caught on the divider causing that damage. Im still learning about nitros, what is it about the OS carbs that get them rated so highly? What OS carb would fit an F4.6?
A good carb is a carb that makes your engine easy to tune and holds the tune, cheap aluminum carbs like the lrp's or sh wont hold the tune, they'll make your engine finicky and allows a "smaller tuning window". OS and Nova carbs are just perfect, even a cheap, low quality engine like a Lrp will run great with one of those carbs. As far as i know, they wont fit your HPI block, but HPI (Force) engine's carbs are not bad! Unlike the LRP you wont need to replace it.
I Just brought a lrp .32..never again.lve broke in over 20 plus engines in my time with nitro the engine was the worst to break in and tune...and the crank rusted after a week even with after run oil..none of my other engines have rusted. Sold it as is for half the price..lol
I only run engines under 200$, and the Lrp's are by far the lowest quality engines i own and not the cheapest ones 😅 but now a days there are few choices left when it comes to pullstart big block engines.. so lets not blame lrp, at least they keep selling engines! They should simply lower their prices to be in line with the quality of their products
That"s a nightmare,F***********k!!!Dear Tasty B please tell me exactly which part you need to replace in order that you could have a chance to fix this engine and I will try to help you to find it,even it"s not available on the LRP shop and so one.. I"m nearly ready with the tune of my LRP 28 spec 3 after the slightly mods in order to use it properly with the 16% nitro fuel,it"s funny,if you believe or not,I was thinking about you after i was running it! Unfortunately it was simply allready to dark in order to make a visible video ,I"ve tried this,but the quallity was to crappie ,lol. I will do my best to record the beast and put it here on RU-vid for you :-) Anyway,my condulations for this terrible happening,I"m so sorry about this my dude..
How you doing my friend, sorry for the late reply but your comment doesn't appear in my notifications nor in my channel i can only read it on YT studio! strange! Thanks for your kind words, i appreciate. The part is lrp 38534, i think any lrp.28 crankcase will fit. I just orered the sh28 8p, wich i belive is the same engine, we will see very soon. Hope to see your lrp running soon
@@TastyBRC Hey! I"m making fine and you? That"s really very strange! So the only thing on the engine which must be replaced is only the crankcase? If for any reason the crankcase that you ordered not fit ,let me know,I"m plenty sure that I"m able to find one at least one in used conditions.. Nice regards from Emsland,Germany Miguel /V-one
@@voneboy Im fine thank you, yeah the only damaged part is the crankcase, hopefully i can replace it with the sh crankcase. Time will tell... cant wait to run this engine again and then moddifying it, im pretty sure i can power this thing up very easily.
If the 32 block is the same I got one you can have nothing wrong with it I was on fourth tank had a runaway and flipped upside down full throttle and blew the crank block is fine
DavidRC installed a KE25 carb in a losi lst XXL wich i belive is running an sh based engine, i'm pretty sure it will fit. The .32 carb has a heat insulator and restrictors, should be better but we all know that lrp carbs are not great, the kyosho carb should be a good upgrade
What are odds for that... Well, at least you got to do the best part (running in) 😂 The O.S carbs are the best. They should put them on every engine at the factory and stop designing their own.
Damn... Sorry for ya man. Yeah keep hands away from LRP. Had them ran them broke em... Only one Worth interest is the 21zz.all 32s and 28s meh... Get a dynamite big red 28. Thats a beast
I'm very disappointed with the lrp quality and wait to see the .32, it's much worse!!!!!!!🤮 I really like the Big Red, 6 ports, a screamer! I could buy one🤔
What's up bro! These engines are pretty bad you can see why I haven't fitted mine in the buggy, there is no way it will fit with the standard backplate as its way too big. :(
@@TastyBRC i'm fine thank you.👍 Hope you are fine aswell! 👊... Yeah, the hit was terrible.... On the rear bumper and chassis?..... But still, this kind of damage... Jesus🙃 Well, i've been told that we are both expected to buy a new savage..... 😯
@@kings-racing Hit the rear skid plate, my chassis looks like a sandwich. I was waiting for the kyosho usa-1 but i like the New savage, would you buy that kind of rc?
@@TastyBRC damn. There was a time when i was thinking about a kyosho mad crusher. 3 speed baby🤘... But i didn't buy it. Does the usa 1 have the same chassis as the mad crusher and foxx? Did have a losi LMT, but sold it. Was a eword, Didn't liked it that much. think a nitro Monstertruck is more fun, so yeah..... i would buy that.
What are you talking about? He accidently did a backfip on a curb. Not the engines fault or its performance. Geez can't believe you people blame the engine but when its the drivers fault.
