pm sent to jayslim about cobra tq. Oh and the hybrid gearbox will be fine with a 6.5 i am sure. The driveshaft will be the issue i think

I have found that the shafts hold up pretty well with the power of my 6.5 so far, however I did bend one last night after hitting a curb side on at a good speed ....but Ill put that down to driver error

You're a bloody lead foot Jay.
I've only had mine on the usual 27turn old skool Parma Cyclone yet,I'd rather let things bed in a bit before I go on the hunt for some big power(not driven properly for a good few years either and I'm getting old now). |

you cant just spin the gbox around as it would mean the toe and anti squat would be reverse. I had to modify the pivot blocks on the gbox and make my own motor plate with a external idler gear like the atomic cr2. It wasnt easy.

Tuned RWD Fords used to be my favorite toys. Had tuned Cortinas,an Essy 16 Sport,an Essy Mex,a couple of RS2000's before moving onto Pugs with a 405 SRi,then an Mi16,then a 306 Gti-6 and now a tweaked 306 Hdi D-Turbo Sport. Hey Adey,I thought two of the Cobra's "other" problems were no toe-in and no anti-squat as standard? I run a 1mm shim under mine's suspension hangers to give it some anti-squat. |

they have slight anti squat but not adjustable. The mid conversion was tried at kiddy for a few laps and was pretty good. I just want to build another using my own chassis design.

Had a swift blast with mine today in our Close.
It was on tarmac,so pretty flat and a good surface(didn't get to go to the local bit of dirt last Sunday),but I'm impressed. The thing went well on the factory spur and pinion(80/21)with just a 27turn Cyclone in it. So much quieter on 48dp than with the screaming 32dp of the original Cobra box. Acceleration was pretty good with a reasonable turn of speed too,so I'll be keeping my ear to the ground for a 21 or 19 turn to start with before going for some insane quad to have a bash with.

if your running brushed miggers, i would go with a good 19 turn spec or possibly a 17 turn single. Ideal for the cobra. Its a light car so it should go well. Or just put a good 11 turn in it and enjoy.

Yeah I am still on brushed mate(noo fangled brushless is too much dinero for
Mrs Miggers to authorise purchase of said gear ). The only 19turn I've seen is Ansmann's 19x2 Launcher motor,a shufty on E-Bay doesn't produce much results at all. I can only go down to a 12turn with my old Mtronics ESC,but yep, a 17 or 19 would be good fun judging on how well it goes on the old 27turn Cyclone stock. |

Well,these things really are only a high grip/tarmac car!!!.
I've bought a 17x2 and had a few goes with it down at the locale. Granted,the tyres are pretty shot,but it doesn't like the dirt/very fine gravel surface at all. Even with the slipper backed off it's very difficult to get the power down in a straight line out of a corner. The guy on that Planet Venom site said that once you get the anti-squat sorted you then have to re-drill the rear hinge pin holes to give it more toe-in on the rear because the thing just want's to write it's name in the dirt. Believe me,he isn't kidding at all. It'll turn in well enough and corner on a light throttle setting,but once it's straight and you feed in the power,oh boy,the back end tries to overtake the front. |

rear toe in will help but its more to do with tyres and setup. I have seen this site and i cant agree with some of the methods used (without causing offence). I did see a cobra with drilled rear wishbones to acheve outboard toe in and it looked a good way of doing it. Try redrilling the gearbox to acheve inboard toe in and you will find it hard to keep the wishbones free and it weakens the inner pivot point.

i know that they added washers under the front of the gbox to increase anti squat.

I made up a plastic shim and fitted it to lift the front end of the wishbone mounts. Folks are saying that Proline's Calibers or Holeshots are good on the rears and ribs up front for the dirt/fine gravel gravel surface I'm using. What spring/damper combo would you recommend Adey? |
