Kyosho Superten GP's and FW-04 - Page 6

Mika n ice choise. I have a TR15 rally, and I love it. I also have a Landmax 2 but that is besides the point. The TR15 is comparitvly small, fast and much better than any ready set. I am still waiting for my 4 stroke fitting kit, but I have one for the Landmax and it is a JOY, so much better off road than the two stroke. However if you do tracks, go for the 2 stroke.

Happy rallying

james

Okay, cool. Thanks Jimmy for your input. It definitely sounds that I need to get one.

Question for SteveP, I was looking an old RC Nitro review about the FW04 and Bob H mentioned about thinking of trying a 2 needle carb. Has he done this yet? I'd like to try this method and see how it works before I go grinding on the engine head.

Thanks!

Mika · #**129** 11-30-2002, 03:27 AM

I also remember reading a similar story from another mag and although the 2-needle carb seemed to help quite a bit, the exact model that fit wasn't told. I'm also interested in this, good question.

StevePond · #**130** 12-03-2002, 05:06 PM

Edit - I double checked, and the FW-04 already comes with the two-needle carb. The four-stroke engine comes with a single needle carb and requires modifications to the manifold to installed a 2-needle carb, but it certainly runs better. If you don't have a four stroke, then you already have a two-needle carb.

Dan H · #**131** 12-05-2002, 03:54 PM

Do you know which 2 needle carb Bob used exactly for his 4 stroke?

Thanks Steve.

Im trying to find the kyosho 19 t steel pinion gear (39666-21L), but Tower hobbies lists it as "discontinued". If any of you could let me know where I could purchase this particular gear I would greatly appreciate it.

thank you in advance!

Mika · #**133** 12-10-2002, 02:05 AM

39666-21L is the "Larger" pinion 21 size? Not 19. Which one you are trying to get? Anyway it seems these are both discontinued at Tower

nolanfarmer · #**134** 12-10-2002, 06:35 AM

You can use a PC Pinion gear, #39724-19. It has the 10 mm fine thread but is only 4 mm thick so you need to have a 1x10 mm washer to shim it out. I assume you will use this on the four stroke along with a 25 tooth gear for second.
This is a steel gear and should last longer than the aluminum ones. It is also more economical.
You could also do a 20 and 26 tooth combination for really tall gearing or smaller tires.

I'm considering an FS26SC for a project, and I wonder if it's possible to use a standard flywheel with it.

I know the Kyosho conversion kit includes a flywheel, but I don't know the reason. Are these very different from standard flywheels?

I was hoping to use an MP-6 flywheel and clutch.

Mika · #**136** 12-12-2002, 03:44 PM

I'm not a specialist when it comes to flywheels and clutches, but I **guess** it's because of the much better torque of the 4-stroke when compared to 2-stroke and therefore requires bigger components to be able to handle that. Moreover, you'll need bigger (taller?) gearing, too.

nolanfarmer · #**137** 12-12-2002, 04:12 PM

I think Kyosho is the only one making flywheels and clutch parts for the FS26 and FS40. The flywheel I recieved with my Supeten II Four with the FS26 and the one I purchased at Tower for the FS 40 are steel, and they work well. The one Tower now sells for the FS26 Is a lightened aluminum one and I don,t recomend it for I have made aluminum ones and they are too light. The engine will not idle and the power is very abrupt.
The plastic clutch shoes that kyosho sells for the threaded two speed bell will also burn up quickly if your clutch slips much.

I am thinking of manufacturing flywheels, shoes, gears and such for the OS four strokes for I can see there may be a growing need.

What do you guys think?

Mika · #**138** 12-12-2002, 04:28 PM

I guess there's a need really, Nolan. I also think the flywheels I use (came with 4-stroke conversion kit) are steel and they work well. I've also been using the special clutch shoe, FZW41, which has lasted very well (no wearing at all). I think it's a must-to-have for every FS owner, but it's VERY expensive

nolanfarmer · #**139** 12-12-2002, 05:57 PM

Is that a Tower part #? A Vespal Clutch Shoe perhaps. I have an ideal material similar to what mip uses and is much cheaper. The four stroke does not need to slip the clutch as much so it lasts forever.

Bandini · #**140** 12-12-2002, 06:36 PM

Thank you guys. So, I should look for a heavy flywheel. The one that came with the conversion is discontinued, I think.

I would have liked to be able to use the MP-6 sports flywheel (IF064), because it fits with the rest of the parts, but it doesn't look very heavy, does it?

As for the clutch, there are 3-piece aluminum shoes (IFW136) for the MP-7.5 that should be durable enough, but then you'd need a different flywheel. The MP-6 3-piece flywheel for OS (IFW051) may be a little heavier than stock, but definitely lighter than steel.

Racy makes 4-stroke conversions for the Tamiya TG series, so Kyosho are not all alone.

It's a Kyosho #number. Tower does not carry it for some reason, but it's a black shoe in colour and the material is something else than vespal. Seems a little bit softer than vespal and plastic ones, but it really isn't. Very long lasting fabriq.

I've got a picture of it, you can see the flywheel, too:

Racy's parts look good. Thanks for the tip (wish I could read the Japanese, too)!

You can. Try this link!

Mika · #**144** 12-13-2002, 06:21 AM

cool!

Bandini · #**145** 12-13-2002, 08:03 AM

What about KC045? These are the clutch shoes I had in mind originally, and at least they have 'heavy duty' in the name. According to Tower; "This can be used on 1/10 scale kits if outside edge of the clutch shoes are sanded down to fit properly".

I've been looking for steel flywheels. Both the .26 and .40 conversion kits now ship with aluminum flywheels, and the only steel ones I can find are those for the Ultima. It seems like almost every Kyosho model uses its own unique flywheel and clutch that won't fit any other model. Very strange...

nolanfarmer · #**146** 12-13-2002, 08:46 AM

I have a set of the KC045 shoes, I will look into it and get back to you.
The clutch shoes Mika pictured above looks like they were made from the same Material I have. I would use those if you can find them.

Bandini · #**147** 12-13-2002, 09:15 AM

KC045 is a direct fit with the setup I was planning. This is not for a Superten, but for a project car.

I was planning to use;

IF064 flywheel mp-6 sports
GT020 pilot shaft 2-speed
KC045 clutch parts h/p
MA011 clutch bell 3-speed

These four parts fit together, but if the flywheel is too light and the clutch shoes too soft for the engine, I'm in a bit of trouble.

I could always get the 39673 vespal clutch shoes instead. The flywheel is worse.

nolanfarmer · #**148** 12-13-2002, 12:25 PM

That looks like a great setup. 3 speeds.......Woohoo!
You may need to add some pins for weight in the shoes, but I think it will work well.
I wonder does the flywheel fit the FS26? It does look light. If you need some machining I may be able to help you.

Finally got some shots of my FW04...

Some pics before I hack it for cooling holes.
