1/12 forum
I was looking to do a similar conversion to my sp12m, remove both dampers tubes make up a top plate like yours and use the side shock from a RC12R5, purely from a maintenance point of view
Weight was the only reason i could think of as well why people wouldnt use microshock instead of tubes.
I found a deal on an sp12x by corally. Could someone give a brief description of the pros and cons of this car.
I saw on Stormer hobby site that it use corally wheels. does this mean that you can't use an other brand of wheels?
Thanks

You can't go wrong with some Jaco. The best thing is to ask others racers on your local track, they might get the right setup. Try Dbl Pink front, Grey rear, you may find a chart on the web to get the full range of available shore.
For spur and pinion, Kimbrough, Robinson, PRS get great stuff. I do use robinson for both as that was available at the LHS.
I have tried both single and twin damper plates and have found it easier overall to use the twin dampers. With just the one, you have to use really, really thick stuff in it to get the same effect as the twin setup ( and I mean really thick!). I will get one of the side shocks from the AE car also to try and hopefully that'll be easier. Fibre Lyte in the UK cut out the chassis and parts for me and they have a number of differant types of carbon. I just like the look of the cross weave stuff so that's what I got them to use. Cheers pal, Chris.
Hi Conrad, that's a car that I made up myself and I made two versions of the crossbrace and upper pod plate, one uses twin damper tubes whilst the other setup uses one damper tube.


I have seen twin shocks on 12th cars before but I think due to the weight of them, they are not that popular to use. I have also seen small springs on the end of damper tubes and you are quite correct, turn the ball cups one way or the other and it adds or removes preload from them, so you can indeed set the tweak using this method.
Cheers, Chris.

On the top photo you have the rear body mounts as far back as possible to the rear wheel, this is an idea I have thought of aswell and would of thought that most manufacturers would have adopted by now.
Rear mounts located further back generated more down force to the rear axle, rather than the mounts located inline to the pivot point of the rear pod causing pod sag at speed.

Where do you plan to run it? Asphalt or carpet, indoor or outdoor. My best guess is indoor-carpet but who knows.

Hi mate, I did indeed put the rear bodyposts further back for that very reason. It may not look like it, but the bodypost postition is actually exactly the same for both single, and twin damper setups. I have a couple of other ideas that I am working on, hopefully they'll be sorted sometime soon. Cheers pal.

Wow, you guys are great and full of info. I need some advice! I am going from 1/8th and 1/10th on-road nitro to 1/12th scale carpet indoor. I am looking to purchase a car, brushless motor, etc. Can you give me your opinions on cars +/- as well as brushless systems? Any help and your opinions will be appreciated. A few of my friends are going to be joining me, so I am asking this question for about 4 people. We probably want to get the same car so that we can share parts, etc. THanks Guys!
I know this is a oldschool car but i recently aquired a mint IRS rugrat with a ton of upgrades. I already know even though its old the parts support is still pretty good I was just wondering if anyone had any positives or negatives to say about this car versus newer chassis like the BMI, CRC gen x, or The 12R5. I did a search but alot of the posts are kind of old. Any input, advice, and tips would be greatly appreciated.

We have one local that runs the rugrat and its very fast, just need to get it dialed in to your track.
