FS*MT*4WD

hello
i recently got a used cen gen, she is in good shape other than dead rotorstart battries and servos are weak and need changing. The engine is good, but have decided to replace it with the new black head corsa 7.7

i was not happy with having to service 10 shocks at a time so decided that some 1/5th scale buggy shocks would work good(i will be using four shocks instead of 10).They cost more than the truck so should do the job fine.
they are made by lauterbacher in germany.
Have some hitecs to drop in for the throttle and steering. am still thinking about doing the dual steering mod.

i am wanting to remove the reverse gear as i dont need it to reverse, can this be done?? i have not opened up the gear box yet as it seems as everything is solid and smooth with no play.

Here is some pictures of the progress this far.











any tips or info that can assist me in this build would be great,

thanks for looking

so some progress, stripped the car and cleaned everything, installed a new steering and throttle servo, much better, still have not removed the reverse gear.
removed the clutch and flywheels for the new engine.
installed a hump pack in for power, used a large o ring to seal the battry box.

the engine i have is the corsa black head, should i seal it up?(does it also have overheating problems?) would rather do that now to avoid problems later..

any info/help would be great..

Take the whole engine apart and seal it up.

YOU SHOULD GET RID OF THE BUMPERS ALSO THEY  ARE HEAVY. THOSE SHOCK ARE A GOOD LOOK. MY BUDDY HAS ONE, WE WENT WITH THE 4 SHOCK RTE. AND HE DOWN TO PROLINE 40 SERIES RIMS/TIRES

thanks for the replies, i think i will take the rear bumper off and leave the front on. thanks for the advice.
Dark fire: when you say take the whole engine apart, you mean the carb and the back plate?
some say that the new stuff from rev line is good and does not need sealing... dont all nitro engines need to be sealed?

I disagree with sealing in all cases and think it should only be done if it needs to be. I've never needed to seal a motor myself including two of the new 7.7's.

thanks for the reply rob, the engine is brand new so i just wanted to be sure. am going to do some work and should be ready to fire up this weekend. will do the break in on the bench as the shocks still need to modded to fit the genesis.

is it just me or does the air filter seem not up to the job?imo mud could easily slip in through the sides where the foam sits in the filter. what does everyone else use?
how can i see which generation CEN i have, i understand the color of the chassis but then there was 3 generations of those red chassis?
thanks for the replies.

Can't help you, I am pretty new to the new model of the 7.7 and just bought it out of interest and am still learning about that truck. I am not too big on the air filter either but wn't be mudding so I am not worried.

thanks for the reply, found some at horizon hobby that are called motor saver, they have a outerwears cover too. I think i will have to get one of those.
done some more work, sorted the play(movement) in the lower arms with some shims.
made a exhaust mount out of some alloy i had lying around, still ruff but does the job.
reduced some more weight by removing the rear bumper and the reverse servo.
am going to remove the reverse gear too.






thanks for the replies and any tips are welcome.
