This looks like a proper tough little monster, ive wanted a 2wd for a while now...... got no money ...... must resist !

Update - I was playing around trying to design a new gearbox cover, this i thought why not just drill out the stock one and build up a guard on to of that .... I used wire mesh to bend to the correct shape, then shoe goo over the top to make a unholy cover Fitted the shell as well... Please ignore the fact that it it a team losi on a CEN

UPDATE - extended the shock tower, lightened the battery plate (its all holey now , fitted a plexy glass top to fill the whole space for my huge batteries and replaced all the coarse threaded screws for proper machine screws that wont come loose on vibrations. Next on the list is to print a new CD gearbox cover as the old one does not fit over the clutch bell.

A little more progress on the cen, shocks fitted and 17mm wheel hex's on. I need to finish installing the wing mount and work out how i will fit the batteries. I will be using A123 system cells in a 6S2P config, they are quite big so i will need to redesign a new battery tray. I also need to build/assemble the packs

I will let you know what i think of it, i just need a wing mount now and some shocks

You can fit any shoes and clutch bell to it i think, at the moment it uses the 7075-t tekno alloy ones. I would say that it is quite tunable, a change of spring stiffness will drastically change the slip...i suppose it would be progressive as well (ie slip more at lower rpms) that should make acceleration and braking nicer.

Yep, you can find it here http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXAUAW It is basically a adapter that fits on your motor just like a pinion, however it has some setup options. Electri clutch: You can use it in the same way a nitro does Tekno calls it an "electri clutch", the clutch shoes are held back with light springs and when the rpm's build up enough the centrifugal force spreads the clutch shoes and creates friction with the clutch bell giving you forward motion. Please note that if it is used in this way you will need mechanical brakes...also your motor will run a lot cooler (around 20% cooler) due to the fact that the motor will not be doing the brakes. Trakion drive: The other springs with the straight ends are used for what Tekno calls the "trakion drive", this means that the clutch shoes are pushed into the clutch bell rather than being held back. This gives several advantages, you can use different springs in order to tune how much slip you get because the clutch shoes are in contact with the clutch bell from 0 rpm's you also get instant power. However if you use lighter springs the friction will be less and power will be easier to put down as it will eliminate wheel spin, but i am using stiff springs this should mean that wheelies are available on demand. Using this system will help save your drive train when landing jumps as the clutch should slip before your diffs do This "trakion drive" system will also allow you to use electric motor brakes and will give a progressive feel to them.

Update - my original plan was to use the tekno mount onto a custom servo plate and cut/bore out a hole in the stock motor plate to allow the clutch bell to fit. In a normal center diff mount the clutch bell does not fit if you reverse the center diff, it is about 2mm/3mm short of fitting. However i did not realize until looking at the parts that cen uses 2 aluminum sleeves/bushings over the bearings.... So this means no custom fabrication is needed, the CEN accepts a tekno trakion drive clutch stock. It does clear, anything smaller than a 13t pinion and you would have to shave some off the plastic part. I made a slight error when ordering the chassis plates, it turns out that the GST-E has 4 extra holes in each TVP to hold the center diff. 10 minutes later and a drill soon fixed that... Coming together

Was just messing about and found some wheel hexes, for some reason the pin diameter is 2.5mm ? however i soon sorted that out... Found some pins for them as well, they must have come from my savage days. It may also be worth noting that every thing i make is normally out of a 1 bed flat, my missus must really love me ! (maybe)

Hello all, I have been leeching off these forums for years, i think its time for me to stop being lazy and document something My lastest build is going to be a CEN GST-E with a slight difference, i will be using a tekno trakion drive clutch. This should save the drive line in the event of big hits and protect those already legendary cen diffs The tekno motor mount and trakion drive clutch... I plan to scrap the stock plastic battery tray and servo tray, i will use some nitro engine plate braces (the plastic bit by the motor) and make my own out of CF or alu. Then i will drill a hole pattern for the tekno motor mount in the homebrew plate, the centre diff mount will only hold the centre diff and not the motor. This should eliminate me ripping the end bell off the motor under heavy landings. Will try go truggy style as well, the losi 8ight t body should fit Along with some badlands... Very impressed with the quality of cen parts so far, still waiting on some parts to come through ! Watch this space.

Is that a CEN center diff?
