hi all, mooman007uk from Vancouver Island here.
thought i'd share my latest creation with foff fans here.
full 4130 chromemoly tube chassis, 4 link suspension, home built 4130 solid front and rear axles, oneill bros full mod 57cc zen headed rcmk twin, custom splined driveshafts using hurrax cvd's, honda lawnmower splines, front and rear diffs are redcat rampage centre diff spools and pinions, transmission made from hurrax,fg and himoto gears, modified rampage brakes, vrc propipes, 5b front shocks all round, oddified tonegawa PS050 steering servo. was trying to go with hydraulic steering but the rams suck air when pushed too fast so went with cable steering..
there are way too many pictures to upload now as i've been at this since december full build thread link and photobuck album links are at the end of the post, total close to 300hrs now and build cost of about $3000
edit...i can't resize the photos so the right hand side has been cut off
just before tear down for paint

a few odds and ends to finish and the body work and paint then ready for the one hill that as yet remains unconquered, many attempts with earlier foff ancestors of this one...http://www.youtube.com/user/mooman007uk?feature=mhee (http://www.youtube.com/user/mooman007uk?feature=mhee)
i hope to start it in the next day or 2 ;D
-
That's simply beautiful creation! I waw like :o Can't wait to see the vid where you are running this ;)
-
Destroyer of Worlds!
It only needs panels and custom tires.
-

-

i found, once my steering was finished, that the motor in the oddified tonegawa servo has no power, the motor is bad so hoping Ian Oddie can repair it...for now i can not run it :'(
-
Too bad about the servo, but my god is she looking good! That's the most realistic big scale foff I've ever seen! Good job! 8)
-
how is the progress with the tires?
-
slow :-[ i just have to grind 3 more down, all the paddles are cut out.
i couldn't wait any longer...had to start it and man it sounds sweet...no rear driveshaft in it or i'd have blasted it across the yard without steering ;D

the steering servo will be about another 10 days or so, i'll have the tires done by then
-
Jeeez, that sound good! ;D I want one! :)
-
sounds sweet
that promises some fun for the future.. i almost want to go back to bigscale cars
-
finally got the tires done, used isopropyl to clean all the rubber prior to gluing with CA gold...seem to hold ok
everything else finished

first run 2 weeks ago
http://www.youtube.com/watch?v=AfxnrQmnROU (http://www.youtube.com/watch?v=AfxnrQmnROU)
first run at the hill
http://www.youtube.com/watch?v=25KG_w_5n9o (http://www.youtube.com/watch?v=25KG_w_5n9o)
had some teething problems, snapped both rear axles before even reached the hill the first day, fixed those and then transfers stripped second visit... figured out why it happened and redesigned the rear shaft, transfer gear/brake set up so should be bombproof now, the gear shafts are now braced together so the gears cannot move apart...will find out tomorrow what breaks next...just have to tune the engine as it's still a bit rich before i head out
new set up,

That is an awesome build!
-
sick vehicle! probs for the build
-
This is THE Thing! :o :o
-
i had to further modify the gear shaft to stop the nut unscrewing and the gears coming loose.
i welded a bolt to lengthen the shaft, filed it square. now the nut is not connected to the bearing directly. there is small bearings to ride in the larger brace bearing then a locknut on the back

now it works well and can't come loose again...i tuned the engine and will be going to the hill in the next day or 2...more video will come too, hopefully of "climbmax" completing the course this time
