“This page is for the LutzRC clutch and some tips and tuning adjustments to optimize it’s performance for your driving style.
(Also a what to buy guide for your driving style)

First off I recommend starting with a clutch kit. These kits come with:
Flywheel (Pink or Black)
Vented Clutch Bell (13t, 14t, 15t, 16t, or 17t)*Mugen/Kyosho Style, OR (13t, 14t, 15t)*Tekno/Losi Style
Clutch Nut
3pcs Aluminum Clutch Shoe
3pcs Alum. Clutch shoe shim
3pcs Hard Clutch spring (for aluminum shoe)
3pcs Moderate Clutch spring (for aluminum shoe)
3pcs Soft Clutch spring (for aluminum shoe)
2pcs (5×10) Clutch Bearings (These are very good bearings) (5×11 on larger bells 15t and up) (5×10 and 5×13 on Tekno/Losi style)

Complete Clutch Kit

Complete Clutch Kit – E64-BUP2114

Recommended immediate add ons for the Clutch Kit if you don’t already have them are:
Clutch tool (Plastic material) – AP-X000006
OR OPTION Aluminum Clutch tool – AP-X000013
Flywheel Collet – TU-E021022 (Alpha style Collet, If you run a different engine this could be a good pickup to ensure the flywheel seats on properly)

Next is the optional tuning options to further adjust your clutch set-up. 
-3pcs Teflon Material Clutch shoes – MP01-060201
-3pcs 1.0mm Clutch springs – MP02-090201
-3pcs 1.1mm Clutch springs – MP02-090202
**NOTE- These springs only fit the Teflon shoes and not the LutzRC Aluminum shoes. (However they will fit most other brands clutch shoes. You may also use most other brands springs for 3 shoe clutches including lighter thicknesses than I offer like .9mm or .95mm)

Now for deciding on what YOU need and want to get (Using examples):
As many people know I drive my cars hard, and I am hard on the throttle. Personal preference for me is to use a heavier/harder clutch set-up most of the time. I like my clutch to engage hard and late in general. I do have drivers though who run my clutch who consider themselves more “electric style” drivers, and they get on the gas smoothly and like the clutch to engage a bit earlier. So lets break it down:

1/8th Nitro Buggy:
Usually I run a mix on my buggy. I use either 2 aluminum and 1 teflon OR 1 aluminum and 2 teflon. I do this to try to get different engagement points of the shoes so that all the shoes engage at a different time. I find this smooths out the throttle for me and my heavy trigger finger. It also helps keep it from bogging down if i’m on it to hard out of corners. Here are some combinations I like:
2 Aluminum shoes (1 with Moderate spring, 1 with Hard spring) and 1 Teflon shoe with 1.1 spring.
1 Aluminum shoe with Moderate spring and 2 Teflon shoes (1 with 1.0 spring and 1 with 1.1 spring).

Now again, these are a bit heavier than what some people like. If that is you then you can simply adjust one of the springs down one level to get into an earlier engaging clutch.
Also note that Aluminum shoes will ‘grab’ harder on the clutch bell while teflon shoes will provide a bit more slip. So, oftentimes it is good to use teflon shoes on a looser track, where you want some slip in the clutch, so you don’t spin tires so much. Then the opposite would be to use more Aluminum shoes to on a higher traction track to get that good bottom end snap.

Aluminum Shoes

 Notice some neat features on the Aluminum shoes:
-Flat face, thus does not create a groove in the flywheel.
-Hollow pin which the spring rests on to help dissipate heat, and keep spring from damaging shoe.

Now if you feel you are more of an electric racer and prefer the early smooth engagement of electric you would go with all Teflon shoes and all 1.0 springs. Another top driver ran the LutzRC clutch at Nationals (Thornhill) and he describes his driving in that way, and he said the all Teflon and 1.0 springs were perfect for him.

For me at Nationals I went with all Teflon shoes, 2 with 1.1 springs and 1 with 1.0 spring. So even though this track was high traction I chose to go with all teflon shoes because it was rough in and out of corners, and I wanted to have the clutch slip a little bit and not engage so hard in these rough areas.

So a quick Recap so far:
More Teflon shoes (better for more electric feel. More initial slip when the clutch engages, could be beneficial on loose or rough tracks. Also could be good with high powered engines.)
More Aluminum shoes (more aggressive feel, stronger clutch engagement and ‘hit’. Could be good on higher traction or tight tracks with jumps right out of corners.)

Next we move onto Clutchbells. LutzRC offers both Vented and non-vented clutch bells. So which do you really need?:
If you are using all Teflon shoes it is recommended to use a Non-Vented Clutch Bell. This is because if you get dirt in your clutch the Teflon shoes will get a layer of dust on them and cause more slippage which will create more wear on the shoes and poor performance on the track. So use a non-vented bell with all Teflon shoes.
If you are using all aluminum shoes it is beneficial to use a vented clutch bell. This is because it will allow some air flow over the shoes and help to keep them cooler which will give a more consistent and longer lasting performance.
Now if you plan on mixing the shoes I find it doesn’t matter so much which you use. Generally though if i’m using majority aluminum shoes I use vented. If i’m using majority teflon shoes I use non-vented. Overall, the aluminum shoes will help clear the dust from the inside, and thus it won’t negatively affect the teflon shoe to bad.

13T Vented Clutch Bell

13T Vented Clutch Bell

LutzRC offers 13t-18t non-vented clutch bells and 13t-17t vented clutch bells for Mugen/Kyosho style bells. Also 13t-15t Vented and Non Vented for Losi/Tekno style bells.
Please note that the LutzRC 15t, 16t, 17t Vented bells*Mugen/Kyosho style*, use a 5×11 clutch bearing AP-X000014 as these are more durable for the larger sized gears. While all of the Tekno/Losi style bells use a 5×10 outer and 5×13 inner bearing.

Some other things to possibly keep in consideration is wear:
Aluminum clutch shoes are going to wear out the flywheel pins in time. It’s just part of the process and something to keep an eye on after much use.
Teflon shoes probably won’t wear out the flywheel pins much if at all. Thus these are good for those who are looking for more longevity out of their parts.

Now because we don’t offer a Teflon shoe clutch kit you could piece together parts if you know you don’t want Aluminum shoes.  Here is a quick sample of what you would need if you didn’t want to get the clutch kit:
-Flywheel with Clutch Nut (pink or black) E60-BU*2134
-Teflon Shoes- MP01-060201
-1.0 springs – MP02-090201
-1.1 springs – MP02-090202
-Clutch Bell (non-vented) TU-E0210(48-51)
-(5×10) AP-X000011 or (5×11) AP-X000014 clutch bearings
-Clutch tool-plastic material – AP-X000006
-Flywheel Collet – TU-E021022 (again, if you don’t have an Alpha style collet could be good to be sure you get best performance)

Personally I keep it pretty simple in Truggy. I run all aluminum and all Hard springs. I have heard of others liking all Moderate springs, or a mix of Moderate and Hard.

I hope that answers any questions you have regarding the LutzRC/Alpha Plus Clutch system. If you have further questions, please don’t hesitate to contact me though Facebook or at my e-mail: lutzinator408@gmail.com
