Also, use the long ones on the rear, they will give more down travel.

I think the new kits have solved the dogbone popping out by using shorter arms.

I just picked up a new OFNA truggy starter box for the TR yesterday and when I tried to set it up for the TR I noticed that the flywheel will not make contact with the starters wheel as the engine sits to high.My TR is the RTR version and it has a couple of shims between the motor and the actual mount for backplate to chassis clearance.What would be a better solution between grinding down my chassis so the backplate will sit down into the cut so I could remove the shims or buy a different backplate to remove the pullstarter to lower the engine?Will the LRP Spec 3 truggy backplate fit the SH .28?

I always chamfer the sides of the flywheel slot on the chassis to help give a little more room for missalignment if starter wheel. Just putting a 45 Deg. angle on the left and right sideof the slot it will make a big differance.

I think you will need to remove the pullstart and install a different backplate, possibly new motor mounts, this has been discussed here before.

Fuzz- I'm pretty sure you will have to get a backplate for the engine in order for the starter box to work. I have the RTR version, and I got the sportwerks backplate, and it fit perfectly on the SH engine. on amain hobbies, search for backplate, and the first one--I believe--is the right one. It should cost $11.99. With the backplate, you will be able to lower the engine off the spacers, and have the flywheel be able to touch the wheel. Unless you want to do some serious dremeling to the chassis, this is the easiest fix.

I have a TR Arena FRE and I am using Kyosho universals. I am considering purchasing a BCE chassis. My question is, can I still use the Kyosho universals or do I have to go back to using the stock dog bones? Thanks.

Default installing a backplate CEN SH .28

I am installing a back plate on a Cen SH .28 to elliminate the pull start. There is not enough clearance, so I am going to have to dremel the crankshaft. It seems to be imposible to slide the connecting rod off of the crank (I have removed the sleeve). I don't think I should have to remove the piston? Has anyone had this problem and could you please offer some advice?

Thank you

If you can hear a 'grinding' noise when you cycle the piston after putting the sportwerks backplate on, it is most likely to be the 'nub' at the back of the crankshaft hitting the groove or channel on the backplate (i had this happen on two of the backplates). The nub was used previously to 'grab' the slot on the old backplate when using a pull or rotostart system.

Solution is to either
a) slightly dremel the channel on the backplate where it is grabbing (you will see the point this is as the channel will be scratched). Be patient and do small amounts at at time then check clearance by refitting backplate.
b) remove the crankshaft and dremel the nub.

Option a) is easier though a little more time consuming. Whichever one you choose, make sure you flush the dremeled area with a little fuel before each refitting to remove any metal particles.

on the centre front you can continue to use the Kyosho universal (that's the rear one from the MP777 buggy) if you use a .8mm shim between the universal and the diff housing. You can also use the CEN buggy rear universal.

if you have been using the 138mm ST-RR universal on the centre rear unfortunately it's just too long. i had them as well so tried to make it work with my BCE chassis by dremeling 1mm off the shaft of an old hot bodies pinion gear i had (the one you will need for the small gear conversion) and it kinda worked but in the end I have gone back to the dogbone on the rear for now and the CEN buggy rear univesal on the front.

the good news tho is that CEN will have their new lightened 7075T6 ali universals available to us plebs in a couple of weeks for around USD$35 and i have been assured that they will fit the BCE chassis conversion

b) remove the crankshaft and dremel the nub.

Thanks, that is exactly what I am attempting to do, but I can not get the crank out. It seams impossible to disconect the rod from the "nub." Can this be done without disconecting the actual piston from the rod?

Thank you

First remove the piston sleeve .
Then with the piston/rod at the top of the stoke it should slide off the crank.

That is exactly what I have done, it just seams like the "nub" is too long? Anything else I can try? I thought it would just slide off?

You could get the sportwerks backplate for the SH engine. It's the backplate that I bought, and it's only $11.99 at amain. It already has "dips" on the corners, so no dremeling is required. It fits perfectly, and I didn't mod anything.
