For tyres I think you're best off with foams for 1/10th but some rubber tyres were recommended to me when I was running 1/10th but I can't remember what they were, ... @pieman5 do you remember? Was it Sorex? Yeah either Sorex 28R or 32R. I have ran them up to 94mph and a few others have gone over 100 with no issues. Personally these are always my preference if aiming for speeds under 100 as i found they gave more grip over foams once they had some heat in them. For foams you can't really go too far wrong. If you are looking to get to 70 and then stop, id look at running 37 or 40 shore. If eventually wanting to push further you'll want 42 or 45. Im curious as to why you chose a Strada to do this with? An old Xray or Schumacher race chassis would have been more suitable in my opinion, but good luck anyway. I'll keep watch for your progress 👍 Edited January 30, 2021 by pieman5 2 Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted January 30, 2021 Author Share Posted January 30, 2021 @Redback im sticking to 3660 3300kv motor was looking at 3670 but its a large esc so want room for it all, will play with pinion size to get it running best 1 Quote Link to comment Share on other sites More sharing options...

Lone-wolf Posted January 31, 2021 Author Share Posted January 31, 2021 I have mentioned this to the wife and did not get told of lol happy days, and just ordered the Speed flea V1 on the basis i can also use it in my aircraft, so i will find out just how fast my reptile dragon 1200 twin really is 1 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Lone-wolf Posted February 1, 2021 Author Popular Post Share Posted February 1, 2021 Dug out a motor cooling fan and fitted a futaba plug, and soldered up a series connector XT60, as i may pick up a pair of 2s high C 4000mah lipo`s for the final speed runs, at least i feel i am making a start while i wait for the car and parts to arrive, and here is a google image of the car i will be based on 4 Quote Link to comment Share on other sites More sharing options...

For now its a surpass hobby 3660 3300kv, just cheap motor for testing, may upgrade it at a later date, here is a odd thing, 5200mah 2s lipo does not really fit, but the 2650mah 4s fits like a glove Quote Link to comment Share on other sites More sharing options...

There are all sorts of little tricks speed runners do to get ESC's etc to fit in smaller scale vehicles or just ones without a lot of space. What's it look like under the shell, ...any pics? Do the chassis sides reach all the way to the edge of the bodyshell is what I am looking to know?

GMballistic Posted February 4, 2021 Share Posted February 4, 2021 Looking at that @Jack Reacherstraight away I can see you do have space to work with. It's just going to depend on whether you're willing to cut and modify the chassis. I've marked the wasted space that you can use in red. If it was my build firstly I'd cut the side lips off the chassis. Then I'd buy some carbon fibre plate from eBay to use as chassis extenders. On the battery side it will give you more room for larger capacity or simply wider batteries and on the motor/servo side it will give you the extra room to fit a larger ESC. This is an eBay seller I have just recently used and bought two of these carbon fibre 2.5mm thick plates for a build I am working on. UK seller and not a bad price tbh. Link: https://www.ebay.co.uk/itm/Small-3K-Carbon-Fibre-Composite-Sheet-2-5mm-x-200mm-120mm-Twill-Weave-Black/353065393762?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 You might only need one sheet of that for the Strada simply cut in half to do both sides. Just remember proper PPE when cutting if you do go the carbon fibre route. I suggest carbon fibre because it's very light weight and also very strong. You could use aluminium of course but more work involved to cut and heavier. Do you think that's something you would try or are you going to try another way to get the ESC to fit? 2 Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 4, 2021 Author Share Posted February 4, 2021 @GMballistic wow, great reply, but cutting carbon fibre may not be on my pay grade so to speak, limited tools and near zero workshop area, but at this point lets not rule it out, i know what your saying on PPE, lets wait an see what real size the 120 is and not rulling out a different esc/motor set up even if its just 3s, options are open here, also half interested in a 1/8 like a Hoboa GT 1 Quote Link to comment Share on other sites More sharing options...

GMballistic Posted February 4, 2021 Share Posted February 4, 2021 I cut and shape carbon fibre with my Dremel so nothing fancy but get what you mean as it is messy so best not done in the kitchen. Lol. If you do go 1/8th the Hobao GTB is a great place to start as you can buy it as a roller cheaply and the chassis is longer so can take some big can motor set ups. 1/8th scale is my favourite scale for RC tbh especially for speed running. 1 Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted February 4, 2021 Author Share Posted February 4, 2021 Its early days on the Hoboa i need the senton to sell first, shame but it was just wrong car for me, i feel something like the Hoboa would get a lot more use , shame i dont have to budget of Raz Shifren 1 Quote Link to comment Share on other sites More sharing options...

Redback Posted February 5, 2021 Share Posted February 5, 2021 Shoot me for saying this isnt a hobao gt just a hyper 7 with road wheels and shell? Car looks great mate, got a sealed transmission cover, much bigger center brace, whats she weight in at? Looks like theres plenty of room to mount the esc on the top chassis brace, like i did, bit of sponge you get with lipo underneath the esc and a cable tie to hold it down firm. If you make a pan like menntioned above you also get lower cg and more weight over the wheels so technically should get better performance. and can put the esc were the battery would normally live. Is your esc waterproofed / potted. I noted vs a non potted esc thats much lighter, I can have a bigger motor and higher power esc for 1g less weight lol woo power!

Acidsnow Posted February 5, 2021 Share Posted February 5, 2021 Ye could mount the esc on the centre brace Jack, where the radio box is on ma tamiya. Should fit within the roofline. 1 Quote Link to comment Share on other sites More sharing options...
