94grasshopper 0 Posted July 26, 2010 the thing is some times when going in a straight line because its so light if it hits something on the road it can go out of control and spin out and roll Share this post Link to post Share on other sites
glassback 1 Posted July 26, 2010 It's a 'characteristic'! What makes it so much fun is you never know what it will throw at you! I can put my Hornet down on the workbench at the end of the day and when I return in the morning it will be on its roof ! They are that unpredictable !! (not quite but you get the idea!!)

dimblum 1 Posted July 26, 2010 If you are just bashing there is one way you can make the GrassHopper immune to rolling over.. There is a vintage hop-up made by Parma that allowed you to mount a second set of rear wheels (and front wheels if you like) to the existing set of wheels.. This makes the wheelbase incredibly wide - so wide in fact that the Grasshopper cannot rollover even when you take turns at full speed - it will just skid a little.. It should not be too hard to find these adapters on Ebay.. I did this to my runner Grasshopper and tested it out.. I have attached a link to my showroom about the hop-up and a trick to lock the outside wheels (since they normally free-spin and loose traction). Please don't use these if you plan to run your Grasshopper on an RC track for vintage racing.. The track manager would not allow a car to run with such a wide wheelbase. http://www.tamiyaclub.com/showroom_model.a...4&sid=13616 Hope this helps. can any one tell me how i can stop my grasshopper from rolling over when i go round a corner because i have got a 540 motor in it Share this post Link to post Share on other sites
94grasshopper 0 Posted July 26, 2010 ha ha but i was wondering if i could prevent it from happening by some how lowering the car a bit to stop the paint from scratching Share this post Link to post Share on other sites
dimblum 1 Posted July 26, 2010 It would help for sure, but probably not enough to prevent a rollover at full speed. There is another vintage hop-up kit made by BoLink that included parts to lower a GrassHopper or Hornet for street racing.. I didn't see one on Ebay today, but I have seen them in the past.. ha ha but i was wondering if i could prevent it from happening by some how lowering the car a bit to stop the paint from scratching Share this post Link to post Share on other sites
taliesin 260 Posted July 27, 2010 Send TA Mark a PM to see if he has tips. If he can keep a GHopper on the ground under brushless power, he can probably help you out. I believe he filled a spare tire with lead and mounted it on the rear, which you could try. Might provide a little crash protection too...? Share this post Link to post Share on other sites
TA-Mark 195 Posted July 29, 2010 Grasshoppers bounce ALOT with the kit suspension. This doesn't help with the suspension ocsillating on it's pogo sticks as you attempt to take a corner. Fitting some CVA or an oil filled dampers will solve this to some degree. Use a very light spring and damper fluid on the rear and medium weight spring/fluid on the front. The Grasshopper is not a heavy chassis so 1:16 buggy dampers/springs will do the job. Adding some weight to the rear of the chassis/body will help with the rear end bouncing as all of the rear weight is unsprung in the gearbox. I have 200grams of lead weights inside the spare tyre I have fitted to the rear roll cage on mine. The bumpsteer and odd camber angles caused by the single arm front suspension will make keeping it in a straight line a chore. It's a characteristic of the chassis to many, it didn't float my boat, so I fitted a CRP FX-10 double wishbone front suspension to take away the odd camber angles and bumpsteer. The kit Paddla Trak tyres really only work well in the sand. The Buggy Champ/Rough Rider wheels work much better for packed dirt or tarmac use. Hornet tyres are great on grass and really loose dirt. The rest is all driving style. Brake in a straight line before you attempt to turn. Share this post Link to post Share on other sites
