Tug Posted August 1, 2015 Author Share Posted August 1, 2015 What is that and how did you "make" it? Quote Link to comment Share on other sites More sharing options...
jdbarnes80 Posted August 1, 2015 Share Posted August 1, 2015 It's a lump of aluminium shaped to fit into the empty diff. Directly connects both drive boots and fits into the groves in the plastic bit of the diff to lock it directly to the drive. Its turned, and milled to fit but If you had a bar that fit inside the diff cut to length, hack saw two groves each end for the pins, then put a screw through the plastic part of the diff into the bar to lock it.

jdbarnes80 Posted August 1, 2015 Share Posted August 1, 2015 Yep! Barely run on tarmac anyway, but really its just a back up to keep me running when diffs are being fixed / modified. Sent from my XT1033 using Tapatalk Quote Link to comment Share on other sites More sharing options...

jdbarnes80 Posted August 2, 2015 Share Posted August 2, 2015 Well... 1 pack of fun then 50% slip on one wheel not good when it's a locked diff. Pulled it apart to find the aluminium had been crushed by the force of the pin, which had then pushed and deformed the plastic diff housing causing the slip at one end. My conclusion is that it's the plastic bit of the diff that's causing all the problems! Even with a normal diff. It's just not strong enough to keep everything exactly in place with the force that goes through it.

Tug Posted August 2, 2015 Author Share Posted August 2, 2015 Yeah, the Scorpion really does need a tough diff, it pushes a lot of torque through the drivetrain whilst carrying a fair amount of weight. Quote Link to comment Share on other sites More sharing options...

jdbarnes80 Posted August 10, 2015 Share Posted August 10, 2015 You Smoked the ESC?! Can you send it back and get it replaced? Sent from my XT1033 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tug Posted August 11, 2015 Author Share Posted August 11, 2015 Forget about the servo, they're rot. I binned mine for a 1256. Definitely get the ESC replaced, that shouldn't have vented. Quote Link to comment Share on other sites More sharing options...

jdbarnes80 Posted September 5, 2015 Share Posted September 5, 2015 Finally got my gen diff back from being turned down, have all the bits now need to rebuild, have been off the road far too long. Have some 10k diff oil to use, can't wait to stick it all back and get out again. Yeahhh Sent from my XT1033 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Tug Posted September 5, 2015 Author Share Posted September 5, 2015 F1 quali is as good as the race itself, in my book at least! Diff looks spot on! Spinning nice and freely? The CEN diff is a beaut! Keep us posted! The Scorpion is a great 2wd! Quote Link to comment Share on other sites More sharing options...
Noj Posted September 5, 2015 Share Posted September 5, 2015 Where did you send the diff out to? Nice job made of it Quote Link to comment Share on other sites More sharing options...
jdbarnes80 Posted September 5, 2015 Share Posted September 5, 2015 Lol great 2 wd, yeah a 4wd be a good addition, some day. My dad turned it for me, just had to wait for him to get back from holiday, didn't take long once he got into it. Will let you know how I get on, but after a bunch of consecutive blown diffs I'm holding onto my excitement for a few packs.

RC_Uber_Noob Posted September 25, 2015 Share Posted September 25, 2015 Hi guys just after some help/advice on a scorpion. I have a hpi trophy truggy flux and I'm looking into getting one of these, the write ups seem pretty good and it should be a lot easier to do the servicing on it the that TT. I wondered what the differences are between the standard one and the Baja? Is it just the shell and the tires, or is it more than that? I'll be chucking the standard ones anyway by the sound of it because they aren't so good. I'll be running on some 45c 4s packs, what problems should I expect other than need to strip it down and loctite it all?? thanks. Quote Link to comment Share on other sites More sharing options...

Have you read up on the diff issue? Quote Link to comment Share on other sites More sharing options...
RC_Uber_Noob Posted September 26, 2015 Share Posted September 26, 2015 Yeah need to get a CEN diff is that right? I'm sure there's a guide in here i'll have to have a look for the link. I have had the same problems with my TT, but there's 3 of the buggers in that .That's why I want a 2wd. Does the gearbox cause any issues or just the diff? Is it a good idea to swap to the universal joints as well? I notice damage to the drive cups in my TT on 4s . Quote Link to comment Share on other sites More sharing options...
Tug Posted September 26, 2015 Author Share Posted September 26, 2015 Gearbox is fine, just the diff to sort. The drive-cups are fine, didn't cause me any issues. 1 Quote Link to comment Share on other sites More sharing options...
RC_Uber_Noob Posted September 27, 2015 Share Posted September 27, 2015 Think I've found a CEN diff. it doesn't matter if it's a front rear or centre does it? How much should they be? seem hard to find. And what real differences are there between the different types? Just missed out on a Baja from Germany for 370 .Don't want to order from USA.

pedro Posted November 12, 2015 Share Posted November 12, 2015 Hi guys. I'm new here and although no expert I'm not entirely new to RC.I've been looking at the Scorpion XXL as a possible purchase and reading some of the information in this thread with interest (haven't read it all though yet). Diff problems aside, is there anything else experienced owners would recommend might need attending to soon after purchase?I anticipate pulling it apart and reassembling with Loctite. While it's apart is it worth installing ball-races? Any other weak stock parts that would benefit from an early upgrade? There's a bit of talk about tyres - what's recommended?For info it'll only be a casual basher and I will probably run with the stock motor/esc/3 or 4S lipos for a while.Anyone got any good sources for spares and upgrades, etc that they wish to share?

robwft Posted November 12, 2015 Share Posted November 12, 2015 selling mine as a roller, t'bone front and rear, no shell, extenders on the rear, £100 plus p/p if your interested Quote Link to comment Share on other sites More sharing options...
