RE: HOW IS THIS POSSIBLE
Aren't you missing something, if the engine is hot enough to melt the mani it must have been so lean I imagine your piston is also melted or extremely burnt.

RE: LST2 center diff
[quote]ORIGINAL: Grits A diff only distributes power to whatever is driving. The fron and rear diffs distribute power to the left and right of the car. An open diff will allow all the power to the wheel with the least traction. Thicker oil in the diffs slow down this transfer of power to the wheel with the least traction and therby allow the other wheel to pull. Thia goes for both ends. Since there is no center diff the power from the engine goes front and rear equally. As long as all 4 wheels have traction they all pull. A center diff will allow power to the front and back unequally so if one end has a tendancy to lose traction you put thicker oil in that end to control the loss of traction and thinner in the end that always has traction. The center diff distributes power to the ends of the car and usually has an oil weight that is between the front and rear. The front and rear ends travel different paths through a turn and a center diff allows the ends to stay moer "locked up", so to speak, to provide more traction while the center diff unloads and allows the car to turn. Under braking the front and rear can also provide more control with a center diff, I think. The big plus of a center diff is it allows the car to turn better while still putting a lot of power to the wheels. This is not totally a perfect description but the basics are still there. Hope it helped.

RE: What weight diff oil are you using ?
I took Adams advice on my basher LST, 10k front and rear and it works great for bashing, for racing I am sure you would play around with different weights but for bashing 10k is a good starting point and much better then the stock grease. Quick tip when using fluid always replace the seals, I used 2d's tip and got the 8ight diff seal set which is way cheaper then the lst set and includes enough to do three diffs and includes the o-rings.

When you turn the outside wheel travels further then the insde wheel so the diff allows it to turn faster to keep up with the inside. The thickness of oil in the diff controls how much faster the outer wheel can turn, thinner oil makes the diff more free and thicker oil makes it more locked, thick in the front will makes the truck push into the corner as the front will not want to steer, thick in the back will make the back drift as the back will not want to steer so will try and overtake the front. It has nothing to do with the 4x4 system and does not affect anything other then the way the car turns, although if you locked both diffs the car would have amazing traction as all four wheels would be permanantly engaged but the truck would hardly steer and at speed would probably not turn at all. Locking just the back diff can also make wheelies easier as one wheel cannot loose traction like it will with an open diff, but again steering will be very poor.

RE: test ur knowledge
I will add this about buggy's, they are very, very fast with the right engine and with the right driver extremely fast round a track unless the track is very rough terrain with massive bmx style jumps they should leave most truggy's for dead, the handling and steering on a buggy is unbelievable. I used to have an RB powered xb8 as a basher and it drove so much like it was on rails that I found it no fun for bashing it pretty much drove itself and I have no idea how to set it up I just ran it as it came from the previous owner. But one thing thats seems to have been missed is that 1/8th buggys are without doubt the strongest racing class cars out there, they really do refuse to break, obviously a savage could survive a 40ft jump better but get an mt cartwheeling or rolling and bits fall off. A buggy will roll and flip and cartwheel all day normally land back its wheels and keep going. They can't however plough through long grass or drive across a ploughed field flat out like a truggy so they don't quite qualify as the best basher. Awesome fun though and due to being a bit lighter then a truggy if you can control one in the air properly they will literally fly, I know literally nothing about setting up a buggy nor how to control one in the air but I took my xb8 to a local small tight bmx track and launched it at the triple, I cleared the whole thing and landed some 8ft the other side.

RE: CEN GENESIS TOP END SPEED PROBLEM
What are you playing at putting those tiny wheels on the cen? the cen has some of the biggest wheels going, those are smaller then the stock lst wheels! of course it has killed your top end. The highest speed gear is now probably barely the same ratio as the lowest gear on the original wheels, just put the stock ones back, on can't see what is so hard to figure out?

RE: New Fusion .28 reported to do 80mph!!
I may be way off here but a comparison that immediately comes to mind is full size cars, yes there are some small engined high revving cars (mainly hondas) that go pretty fast, but most take a lifetime to get to their top speeds because they are relying on revs and not hp to get to their top speeds and if you slow down and then re accelerate it will bog down and take ages to pick up because at these high rpms the engine is not making much torque. Now look at bigger capacity, bigger hp sports cars, most will get to their top speeds much easier and because they are geared taller to make use of the power they have a lot of torque near their top speeds. I don't want to start any sort of war here and don't bother to start arguing about how your 1.6 vtec civic is faster then everything on the planet beacse the argument is worthless, fact is the fastest cars around have the most hp. For reference the only reason that manufacturers don't just fit massive 500bhp engines to everything is bacause in a real world car, not a drag car you need to consider, fuel economy, handling and space limitations.....

I always got problems with 'hot-starting' because it ALWAYS vapour locks. Wouldnt recommend it, but if your looking for a cheap deposable engine then get it by all means. I was quite impressed with the power of it for a RTR engine and should do you nicely for a gallon or two... [/quote] Sounds like the mach 15 that they put in some of the xxx-nt rtr's worst engine I have ever owned, bought the car with no compression fitted a new piston and sleeve and its never worked right and now less then a gallon on it loosing compression again.

There is a post floating around where 2dmax correctly states that the high speed gear set is in fact a close ratio gear set and will actually make the truck slower not faster, as said the only way to go faster is 8man pinion and delrin gears.

RE: New Guy with a Losi Monster
[quote]ORIGINAL: tabraha I see what you're saying now I don't know how I didn't notice that! I wonder if the R/C shop that had it on consignment swapped them out and didn't pay any attention (It came with 3 sets of rims/tires). I will say this much, evidently the tires dig well mounted either way b/c I spent 4 hours trying to retrieve the little bugger after I got it stuck in a drained pond I was trying to measure. The tires just dug right in and unfortunately sank it down to the chassis. I am going to try and seal the tires so I'll flip them around on the rims when I attempt to seal them. I'll see if I can get those cameraphone pics up this week of me getting pulled across the mud in a boat to get out to the damned thing to get it back! As far as the handling being really bad, what handling!?!? Yeah it's really that bad! Not hard to roll it at speed to say the least. I'm ready to be done with this project so I can slap the smaller tire/rim package on it and open it up a bit more. [/quote] No need to change the tyre you should be able to swap the wheels from one side to the other, I can believe you have an LST and it doesn't handle well, I can feel your pain brother. Get some stock or smaller tyres on there the handling will blow you away.

RE: M26SS & LRP
Jeez just because the block id the same don't make it the same engine, look at the automotive world, the chevvy v8 blocks and the rover v8 block have been used by many different companies yet some make 200bhp some make 1000bhp. The sleeve design and timing are what makes these things work a slight difference here can make masses of difference. Would I be right in saying that out of the golden lion blocked engines the LRP spec 3 is the most powerfull? would be cool to see a list comparing the different engines as some are harder to find in the UK and others are cheap and easy to find.
