Jimmy,

I wonder if your foams are too hard for the car?

Alot of the RC18 drivers are using 30-35 shore maximum due to the light weight of the car.
It seems the harder foams work on the Blaze cos the Blaze is alot heavier.

Also I dont like the idea of using different compound foams F to R...being 4 wheel permenant drive surely you would suffer handlijg/grip issues by using different compounds?

Just a thought..hope it helps

Looks good.

Xray also offers a variety of foam tires in different shores for the Truck in the right diameter/offset. I know they aren't easily available where you are. Just a heads up though.

I noticed with the larger skinnier foams of Sedans the additional ground clearance provided too much roll and made the truck less neutral in the air. *

If you need more spring choices, the Rc18T springs can work by replacing the bottom retainer. Mini Quake (forgot the UK name) springs work as well. Both aren't the exact sizes so you might need to have some weird looking preload on the shocks.

Hit me up if you have any more Q's.

*Edit: Also, the larger sedan tires can actually create more breakage as they can glance on pipes easier causing more backlash up the suspension. And since the diameter is further from the axle center, more sideways pressure on the hubs under these conditions.

I just got hold of some rc18 springs - gonna try them tomorrow. to be honest though the car was pretty dialled last week and I won by a couple of laps. So I don't think I need to change it too much for that track.
I'm used to the harder front compound, I see it as cutting spikes on a buggy - so you have less grip up front. but I'm not used to foams so I'm not really sure if it works that way.
I used schumacher mini pins last week when I won the club meeting - I forgot to take my foams.

I'm currently running with 3mm limiters in the shocks and 20g of lead next to the motor

Cool beans. As Im sure you already know, other than diameter changing. Foams (especially thinner side walls) wont absorb as much as the small imperfections of the surface it rides on. So your suspension might have to be slightly softer to compensate versus running rubbers. Foam shores effect this as well with the softer shores allowing a bit more absorption than the stiffer.

Just so you can get an idea of how small they run foams here, I have included a picture showing Zack Barrys three cars from the Nats warmup race. As you can get a better sense of tire diameters between them. This was at a carpet only "off-road" track, so the various surfaces you run on at once for the UK club meets may not apply.

As I'm planning to build a circuit in my garden (carpet/grass/sand), I wanted to know if the Xray M18T (Pro) is reliable and handling well without having to mod it. Other options are the Asso RC18B (what do you like the most: buggy or stadium truck?) and Losi Mini-T Pro (although it is discontinued by Losi ).

Handles very well and is reliable from what I can see - I've raced it 6 times and not broken anything and nothings fallen off etc. I actually put some hopups on it today but I don't think it really needs any hop ups.
Theres not that much you can change in terms of settings - but that's probably not a bad thing.

The one thing I put on it today, which is what all the Xray drivers at the meeting also tried, was a wing mount and a normal 18th scale buggy wing. This made a huge difference to the performance - it flew very well in the air and just felt a lot more planted and balanced and easier to drive.

Thanks for the fast answer, I'll ask some opinions about the Asso RC18B and Mini-T Pro in an other topic, after all this one is about the Xray

Sand, if its fine particles may cause some problems in the long run if you have a tendency to run it and forget it. If you however air hose it off after runs to help keep dust from migrating into the pivot crevices, you can expect a long life from your joints.

On another subject..

I'm afraid to ask about this wing...

I always clean my cars after a day of driving (not with air, but the better/slower way), so it shouldn't be a problem I hope.

I tidied it up a bit last night and made it not quite so stupid looking! If anyone ever doubts the effects of even a small wing - I challenge them to race my car before and after!
Mark Stiles got 3RD in the A with his Xray which I think he was really pleased with. I won the B final and I think Tel got 6th in the B?

I need to find myself a scale looking wing now

Jimmy, the wing that comes with the Kamtec Mako Blaze shell is one of the best looking 'scale' wings I know of. I had one on the back of my RC18T truck body as seen here:



But saying that Dan and Simon Osbourne are making the Phatbodies Bender and Greedy wings for 18th scale cars as well.

how do I get in touch with those latter bad boys? I actually used one of the 'phat' wings at the weekend, but it was a prototype and borrowed so I had to give it back.
I've got an rc10B4 wing on the truck now! haha.

Here is a blueprint to cut out a tower clamp wing attachment. You can use the RC18B's wing mounts with it.
