johninderby Posted May 30, 2015 Author Share Posted May 30, 2015 Haven't had a minute to spare this week. Maybe tomorrow I'll get a few hours to actually get something RC done. Completely re-decorating and renovating a house for sale is unbelievably time consuming. John Quote Link to comment Share on other sites More sharing options...

johninderby Posted June 13, 2015 Author Share Posted June 13, 2015 (edited) Finally got around to doing a bit more to the truck. Had gotten fed up of the project due to problems with the diffs and suspension. Diffs weren't smooth running at all so needed to be rebuilt. Unless they're set up just right they will bind. Shocks are rubbish and take some playing about with to get them right. Springs vary a lot but stretching them a bit allows getting them all even. Changed the motor to a 400rpm one. Top speed is still slow but no longer snail like. Found a better servo as well. Has 2 1/2 times the torque. Same case as the original but with a bigger motor which sticks out of the bottom of the case. Made up a servo voltage reducer lead. Only cost a few quid for the parts but has a proper regulated switching power supply with adjustable output. Fitted the Quicrun 1625 ESC and a FlySky Rx.Everything is just held in place with an elastic band for testing. Quick vid of the crawling test. Actually crawls a lot better than expected. John BTW ignore the little logo in the middle, put there by the free software used to convert the video.

Noj Posted June 14, 2015 Share Posted June 14, 2015 Hurrah, she moves! Speed looks OK for the scale to these eyes...wonder if the grip will improve on natural surfaces over plastic? Quote Link to comment Share on other sites More sharing options...

johninderby Posted June 15, 2015 Author Share Posted June 15, 2015 (edited) Brief test with the full body. Brief because the servo failed Will replace the servo and post a longer vid later. Mountains (OK hills, hillocks?) do look a lot better though. John Edited June 15, 2015 by johninderby Quote Link to comment Share on other sites More sharing options...

johninderby Posted June 16, 2015 Author Share Posted June 16, 2015 The only problem now is with the trail truck and the monster Landy I want to build a proper micro crawling course. Hmmm.... A hollow core interior door would make a lightweight base and with foam "rocks" the whole thing wouldn't be too big or heavy to store out of the way.

johninderby Posted June 16, 2015 Author Share Posted June 16, 2015 How about moving first before recreating High Peak in the spare room All right mister sensible you would have to go and remind me.

RCbutcher Posted June 17, 2015 Share Posted June 17, 2015 More planning time anyway, there's that expanding foam too that would be lightweight and it's a mound in a can just spray the course down and wait to paint. Presuming it's non hazardous lol. Quote Link to comment Share on other sites More sharing options...
Deafty Posted June 17, 2015 Share Posted June 17, 2015 Not only that, it's actually very 'carvable'. We use styrofoam blocks glued to plywood, coupled with spray foam to fill the joins. then you have an excellent medium to sculpt with Just remember to really shove the nozzle inside the joins so that when you cut away material there won't be material missing. Once sculpted, plaster it by either spraying or brushing. Plastic hardcoat spray paint will help for added duarability. Then paint. Though not a crawling sculpt you get the idea from this: Quote Link to comment Share on other sites More sharing options...
johninderby Posted June 17, 2015 Author Share Posted June 17, 2015 (edited) Plenty of good ideas online but I was thinking something along these lines but a bit bigger.http://hotwirefoamfactory.com/customer/gallery/modeling_danc.htmhttp://www.ebay.co.uk/itm/Exterior-Foam-Coat-3-LBS-Hot-Wire-Foam-Factory-for-wood-stone-metal-bone-/311364003818?pt=LH_DefaultDomain_3&hash=item487ebda7ea John Edited June 17, 2015 by johninderby Quote Link to comment Share on other sites More sharing options...
Deafty Posted June 17, 2015 Share Posted June 17, 2015 Same thing mate. It's all actually very easy to do Just take your time sourcing material as cost differences will be huge! Quote Link to comment Share on other sites More sharing options...
johninderby Posted June 17, 2015 Author Share Posted June 17, 2015 (edited) Local salvage place often has big sheets of foam insulation board in good condition really cheap. Bought enough to insulate a 14' by 8' workshop for 30 quid a few years ago. John Edited June 17, 2015 by johninderby 1 Quote Link to comment Share on other sites More sharing options...

johninderby Posted July 20, 2015 Author Share Posted July 20, 2015 Really must get the body painted I know but painting and decorating, not too mention a bit of landscaping, taking precedence in the final push to get the house ready for sale.
