I know that if you wish to keep the differential in there, take it out, disassemble it, and grease up the inside some. It'll appreciate it.
As far as my knowledge goes, I think that all the Vanquish cars had differentials. Not a new concept though.

Okay, here's the poop. Yes, it is a differential, and dispite what anyone tells you, it works just fine and there is NO NEED to replace it. Go to the local
R/C car shop and buy some white grease for differentials. Gently snap the differential apart, there is a driven gear on each side and a ring gear in the
middle, just like a real one. turn the diff a few times after you pack it, then open it again and put some more in. Put it all back together, and you will be
amazed at the cornering you can do with that car. All the complaints about these fine cars come from people who didn't pack the diff, or ran them too hard.
But beware! The car is unbelievably delicate. Look out for the mirrors, stacks, windshield, and exhaust. They all break easily, and the cars are no longer produced. On the other hand, lots of us really enjoy the cars, and race very carefully. The larger scale (about 1/28th or so), makes them scary close together on a 4 inch (1/32) track, so run them on 4 1/2 inch 1/24 scale tracks. That's a good looking example you have there, so take care of it. |

Thanks for the advice on the diff. I've been looking at the car all evening trying to see a way to remove the entire rear end from the car. There
aren't any screws that I can see. When I try to lift the entire rear axle assembly out it feels like it's going to break. Maybe this will be my first
shelf queen.

When the car gets a lot of grip, the differential will pull slightly apart, and that's when the differential has problems. Once you pack it in grease, just put three small drops of superglue where the differential halves meet. Most imortantly, let me know when you want to sell this car.

Here is the inside of the diff in question...
This Article Harry did also shows the diff and talks about gluing it back together after greasing.

I haven't had the problem with my Vanquish cras, but so many have said that this minimal gluing is best for them, I give it a lot of credence. And it would
be a shame to let that car catch dust.

Wow, over 5 years ago...where does the time go?
Great Lotus you have there...always liked that car. I agree as well, tune that baby up and run her! "They Didn't Say You Couldn't" - Smokey Yunick

Thanks everyone for all of the help and Harry's article. I got the diff. apart and it was bone dry. I am soooooo happy I didn't put even one lap on
this car before asking you guys and gals for help. I am off to the local RC store to get some grease. I really wanted to run this car and not let it sit on the
shelf. Now I will. Thanks again for the help.

No, you don't NEED to replace the diff but if you run with someone who has, all other things being equal, you will be slower. An open diff is not faster
than a spool.

Its a shame Vanquish is no more on the scene.
They had some wonderfull things ...i miss them

One last thing...
Hey Tang, it depends on the track. The diff is way faster in the tight turns, almost unnatural fast, like a magnet track. On long straights, they are close but the crown gear or contrate is slightly faster. Beware the diff that is a lot slower than a crown conversion! That is a dry diff about to ruin itself. |

What about the usual stuff on these cars, like gluing down the motor or gluing the plastic bushings to the chassis posts? Also, I didn't see any grease on
the pinion/crown gear in the pictures in Harry's article. Should grease be added there as well after the glue dries? Should oil be added where the
differential bushings contact the axle? Finally, do these cars need the wheels and tires trued? More importantly, is there any safe way to accomplish this
without risking the differential?
I'll take my answers off the air. (Just kidding) I got two of these cars awhile back and have not had a chance to play with them. They are beautiful. One the best values going for the time being. (Don't tell anyone, ok?) 50s |

Never had to glue in the motor sir. Light drop of oil on the pinion and crown...usual stuff.
The rear axle housing is held very tightly, so no need to glue them, at least I never saw the need?. No real bushings here to speak of. Just a housing. Yes the tires need some attention. But with the active diff, it can be tricky when sanding. Make sure both tires are making contact with the paper. But really, what we did was replace them with Indygrips. They were much improved over the stock rubber and at that time they were sandable. Funny. When they were released...due to the scale detail issues, most scoffed at them and decided they were useless. I agree they will never win any awards for scale...but neither will 99 percent of my T-Jets or other 1/32 offerings for that matter. The fact is they were FUN to race and they did make them look pretty cool. Accurate? No way...fun? Yes way. It would be great to see these cars re-done and done in a more traditional way. Increased scale accuracy, standard gearing, etc. The differential, although cool...stopped many because changing gear ratios and such was pretty much a non issue.

I agree that most of the Vanquish cars were blasted because they were far closer to 1/28 scale than 1/32.... however this Lotus:
Well.... it was close enough for my liking!

In my opinion, they were more faithful to their 1:1 counterparts than most of the other cars out there. They weren't 1:32, but their proportions seemed to be fantastic. I haven't fooled around too much with these cars, but I generally avoid truing the tires on these. It's high stress on the differential, and I'd rather remove the tires and true them by putting them on another wheel and using a Dremel or something like that. You could actually true them by driving on Ninco track for a while, if you have one available.

After running my new car around a while, I want to change that magnet. Or maybe just do away with it all together. I've never switched magnets in any of my
cars in the past. I just run them the way they are or remove them from the car. Does anyone sell a weaker button type magnet for this car?
SJ Slots, I see you have one also. I hope you didn't pull the car apart to show me that photo of the diff. If you did, thanks. It was very helpful. Joe F. |

I'm not a magnet guy, but how about a piece of cardboard taped over the magnet on the bottom the car? Will that work? I've also read that some people
put cardboard underneath the magnet to raise it up a bit, which also decreases the strength. 50s

In this particular case, there is very little room to raise the magnet as the motor shaft is in the way. I would suggest looking at the Scaley button magnet.
Some of your "Sport" version cars came with a button magnet inside the parts bag to be placed up front. It is thinner and has much less down-force.
So if you have a Sport model, check that bag and see if it came with the extra magnet.
If not, Gene at SCP has these thinner magnets in his online store: SCPM04 Traction Magnets (Neodymium) .375 x.0625 for 50 cents. But you can always check your local or favorite dealer and see what they have. "They Didn't Say You Couldn't" - Smokey Yunick

You can also weaken a ceramic magnet by taking it out, and holding for just a couple of seconds over the flame from a lighter. Heat allows the magnetic
dipoles to randomize a bit more. Be careful, though -- do it too long, and you won't have a magnet any more.
