First of all, thank you for providing this opportunity.

Things I like about the NT1:
1- Easy motor assembling/disassembling, easy gear mesh, durable and true spurs
2- Strong and long life suspension parts
3- Very good team support, almost no unanswered questions or problems
4- Good handling of the car
5- Very successful "plastic" shocks

Things I would like to see on the NT1:
1- A factory team kit which includes all the lightweight upgrades, maybe as 2010 car :)
2- Less play on steering system, between ballcups and pivotballs(not pillow balls). this makes adjusting a little harder.
3- Wire type anti roll bar on front, to make adjusting easier and more precise.
4- Better brake pads and disk.
5- More durable shock towers, especially the rear one.


These are in order by which came first to my mind :)

Thanks

Mustafa

Copied some things from musti72 because on some points i share the same thoughts.

Things I like about the NT1:
1- Easy motor assembling/disassembling, easy gear mesh, durable and true spurs
2- Strong and long life suspension parts
3- Good layout, easy maintenance
4- Good handling of the car
5- Very successful "plastic" shocks

Things I would like to see on the NT1:
1- A factory team kit which includes all the lightweight upgrades
2- Possibility to adjust the wheelbase on the front and rear.
3- Wire type anti roll bar on front, to make adjusting easier and more precise.
4- Better brake pads!! and disk. ( no serious driver uses the stock pads)
5- Better pulleys, they clog up with dirt really easy. Maybe some holes where the teeth sit to let the dirt escape. I tried it and it helps

The one thing i really like to see is a factory kit. I just bought a new NT1 because my current one needs replacing.
But a lot of the parts in the kit become useless when you already have a hopped up car. The following parts won't be used from the original 09 kit:

- Clutch > use high dynamic
- 2 speed and mid axle > hollow versions
- Pivotballs > alu versions
- brake system > teflon pads crossdrilled disk
-screws > titanium

tit. screws are very "luxury" option but I would like to see them as well. There should also be lw spur holders as they affect rotating mass a lot even though weight difference is not much.

Things I like about the NT1:
1- Easy motor assembling/disassembling, easy gear mesh, durable and true spurs
2- plastics are pretty durable, might like to try stiffer arms for high bite tracks
3-
4-
5-

Things I would like to see on the NT1:
1- Al wheel hexes out of the box, seems silly to have to upgrade those.
2- front and rear anti squat adjustment (like electric)
3- 5 x 10 clutch bearings for longer service intervals. or make a more durable 5x8 bearing.
4- the -1, -2 body height adjusters in the kit or for sale without body posts
5- yellow clutch shoe.
6- al pivot balls in the kit like that S team does lol

Hi guys,

Great to ask for feedback. Really like that :)

In general i like the NT1, there's been number of improvements over the years which all helped out (like harder clutch springs, harder 2speed springs, 1degree steering block, new bell tentioner, etc..).

I think the car is pretty complete, but there are some things i'd like to point out:

1. The flex in the chassis is pretty much, the 4mm chassis helps and the alu radio-tray mounts help, but i've been using an optional part long before xray came with it. I think the chasis needs to be stiffer. I also know this is part of the success for xray, as it makes the car very easy. I also noticed some 3mm optional chassis for different cars are actually stronger then the 4mm chassis from xray. I think that's pretty weird :)
In all my time racing, i've never broken a shock mount (the carbon) but i have 2 bend chassis.....

2. I'd like more options.
- length of the front upper arms (keeping the normal rollcenter changes that are possible their)
- length of the lower rear arms
- I really like the way the mugen has it's lower a-arms connected (like an electric car). I think it makes it more easy to get the rear lower arms with less play and make the length change + squat possible.
- less big changes on the rear upper link (rollcenter) The inside changes are pretty big.
- Wheel base changeable. So make it possible to move forward and backwards the lower arms. This would also require more space on the front caster settings.

3. Clutch. The clutch flyweights wear out pretty fast. (the hols loosen). On the normal clutch, its super important to get the bearings right (no play).
I haven't tried the new clutch (high dynamic) but i feel the old one needs some improvements for the normal racer. like the alu clutch bell, wears out too fast (although that is good!). For pro-racers, replacing parts isn't that big of and issue, but for the hobby driver, it sucks :)

4. Pulleys:
- make holes to dirt can be pushed out.
- Also, it seems hard to get the front pulley and exhaust spring good and save. The exhaust spring has little space.

5. I have replaced several front bulkheads because the screws are worn out and i can't fix the radio plate any more. I think this is important for the flex of the chassis, as mounting the radio-tray securely is important.

6. Braking. There can be some improvements made on that part. In the beginning we didn't use the brake pads from xray. Now i have the KM-brake pads and the xceed brake disk. It finally works correctly, but it's also hard to get correct because of the way the brake leaver works.


Well, that's about it :)
Don't get me wrong, i'm very happy with the car right now :)


Oh, and sorry for not pointing out 5 good things and making it 6 improvement points :S

Don't get me wrong, i really like the xray!!

How about metal gears for the pulleys? Right now I have to clean them every time and replace fairly often.

Thanks for the great car.

Hi to all at the Hudy factory,

thank you very much for this great car --- I've a lot of fun with this fine peace of design, engineering and quality!

5 things I like about the car:

-- nice and modern designed box, perfect illustrated instruction manual and large and easy to understand setup book

-- really easy to drive in standard assembly and with standard setup, easy gear meshing

-- all parts are stable and suitable for their function, easy and quick to replace if necessary

-- lightweight design with a low centre of gravity, possibility for custom made tuning

-- spirit of xray team and drivers: you can get help for every question on every race track


5 things I would like propose to change:

-- thicker O-ring in the differential for easier assembly and better tightness

-- more constant production on the shock parts; e.g. the rubber caps have sometimes different thickness and by this the spring behaviour is different; e.g. the small foam parts in the rubber caps have sometimes different height; e.g. the plastic shock bodies have tolerances so the alu cap isn't always easy to screw on; front shocks should be rectangular to the car (now inclined about 10 degrees)

-- further steps for lowering the center of gravity again, ask me for details

-- new break; the actual break with a pin is to simple for this highend car; Perhaps a break with a kind of tweezers to press both pads towards the disk.

-- two pins (appr. 5 cm) screwed longitudinally to the rear carbon bridge to prevent the body from bending when quick refuelling in race situations

Best regards

Hallo guys!

At first I want to tell you that you make really fantastic models.
I drive only XRAY models (M18 PRO, M18T, T2'008, NT1, NT18, NT18T).
Now is 5 years that I start with RC cars driving and 4 years that I discover - XRAY is the best model for me.

What I like on models:
1. very simple and easy to built and easy to understand setup book
2. excelent support for drivers and clubs
3. very durable parts
4. easy to drive (very good handling of the car)
5. easy maintenance

Things I would like to see on the NT1:
1. better brake (more stable)
2. more assesible front anti-roll bar
3. alu wheel hexes out of the box
4. exhaust protectors
5. Air filter (INS-BOX)

I agree with all that is said already, just to add

I would like to see Changed:

1. Better Braking system, some springs between the pads;
2. Better Diff O-ring tired of throwing them when changing oils are necessary.
3. Better Thrust bearing in the stock Clutch, but I have just received the new High Dynamic and it looks like this has been resolved.
4. Alu Hexes with the kit is a must.
5. Less play in the steering
6. Car needs more steering

A few wish list items.
    - 2 piece top deck to make it very simple to change the front belt.
    - Alloy brake pulley. The plastic one strips quite often on our somewhat rough track.
    - Easy change method for the rear belt. ie. somehow reduce the number of screws that need to be removed to change the belt.
    - Alloy rear bulk heads. Needed as when you change the rear belt often, the plastic thread in the rear bulkheads wears out relatively quickly.

Thanks.

Hello Xrax,

what I like:

- Easy motor assembling, no gear mesch every time
- durable plastic parts
- easy handling
- easy maintenance
- the bearings

what I dont like:

- THE FRONT ANTI-ROLL-BAR!!! PLEASE CHANGE IT, it is not easy to set up (tweak), binds the suspension, effecs the downstops in both ways
- side belt make the whole drivetrain have more resistance. Front and Back train as single runs very smoth
- better brake pads
- better brake system
- easier change of roll-center

Thank you!

Stephan

been thinking about this one for a while, and although I have not realy came up with anything earth shaking for changes, a few things do come to mind.

The way that the rear bulkheads are made, can you come up with a 3 peice -bulkhead to change the rear belt quicker, The way that the camber link bar is mounted to the accentric holders for the rear diff, do the same for the 2 speed shaft. 4 screws to lift the 2 speed shaft out would be cool.

Also, go to a different setup for the front mid shaft. Leave the pully out in the open and use 2 bearings between the side belt pully and the front belt pully....but don't make it part of the front left bulk head.

come up with a chassis stiffener for the left side of the car. I find the the car seems to have a "tweak" in it and all you have to do is "pop" the car back by pushing down on the front and rear of the car over an edge of a table. It is a very small amount of movement, but to cure this for my car, I cut a new top deck with smaller mounting holes. The screws are tight going into the top deck and prevents any shifting/movement when tightend down to the top-deck stands.

For the pully's, please mold them with holes on both sides, or come up with a metal side plate with holes to get rid of the dirt that gets built up in them. When running on a less then perfect track, dirt gets packed into them and wears the belt out too quickly.

With the radio box being a useful item to protect the radio gear, a shield to protect the gears would be a useful option when runnning on sandy tracks.

With the roll-bar/handle, I've been using 2 screws to keep the tie-strap for the fuel tank lid in place. Would be nice to have a nice slot to slide a tie-strap through, like what you have done with the rear shock tower.

Any way to lower the engine down? Dropping it down about 2mm where the bottom on the engine is down into the chassis. I know that this would move the mesh location of the gears, but lowering the CG might be helpful.

With the hard front bumper being more weight than the stock one, precut holes in areas to remove weight to make it the same as stock would be nice.

Thanks
James Burrows

one more small thing that I would like to see available as an option. Shims for the axle to take the play out of it. The axle stub seems to move about half a mm back and forth. I've made a few shims of my own, but a package of shims would be much better. If your not sure what I am talking about, push the axle stub in and out on the upright. I know that if you take too much slack out, the bearing will bind up, but if you can take even half of it out, I think it would be smoother overall.

So, xray is working on a new car? If so.. any release info?
It's kind of interesting for the ones who want to drive the EC-B. To prep well, you need a new car and spares, but if a new car is comming, then rebuilding in the winter break has no use...

My NT1 was a nice build. I really like this car.
1) All the parts seem to be marked nicely and had great fit.
2) Motor mount is real nice, setting gear mesh goes fast.
3) Hinge pins fit smoothly without having to use a reamer to make them smooth inside.
4) Factory setup feels nice. Very solid car.
5) Plenty of fine tuning adjustments for track conditions.

Things I think need changing.
1) Needs aluminum hexes in the kit- not as an option
2) Motor mount needs to be changed for Novarossi motors. I hated grinding a brand new motor just so it would clear the screws on the top of the two piece mount. I'm still not over that one yet!
3) Brakes feel weak (fade after a few minutes)
4) O-rings in the diffs seem hard to seal with thicker fluids (front)
5) The allen screws that go into the rear hubs need to be longer, even when I use Loctite they still seem to come loose at the camber link. My friends' did the exact same thing too.
6) The hexes that hold the pivot balls seem hard to thread the first time.

These are some ideas that I see from experience with the off brand cars. This is an awesome car, I will report more as I get time to run it more and get used to the way it handles differently from what I have been used to.

Hi, about the things i like of this model i agree with the other users specially for the motor mount that makes very easy the settings of the engine.

I don't like the "Composite Front Middle Shaft Holder". I think that will be modified moving the internal pulley out of the holder for a faster front belt change!

It always take time to readjust the front aniti roll when the plate is twisted and the front downstop cannot work well without a proper front anti roll. That needs improvement.

I finish to mount my new Xray EC edition. At momment I agree with the option parts included, but:

-It hard to mount the outer nut of the pivot balls. take long time... Maybe with a double thread be more easy to screw it. :?
-turnbuckles, I prefer ones with a hole instead of a square for screw.
-A micro switch for the radio would be wellcome for the closed radio case users.
-Mounting hole for the micro switch in the optional carbon fiber receiver plate :wink:
