Got a vid up... had a few problems with the pinion staying on, but the red loctite is holding it in place now...
My ESC, Lipo and motor temps are 50degrees c and below!!! Great temps... i was thinking about increasing the gearing but i am very happy with it... I will extract more speed by using an 8s for speed runs on the road. Cant decide on what ESC to get...??? http://s878.photobucket.com/albums/a...rent=001-2.flv |
122*F, those are great temps for sure. Looks to have plenty of power and is nice and sharp on the steering, I think you got that setup pretty damn well. As for a future HV esc, I still say wait for the Castle one to come out, shouldnt be too long now- cant beat having proper brakes and reverse..

Thanks a lot neil!
Its running nicely... i may lower it a little bit more so it handles a little better when im not jumping... Going out now to see if it can handle air with the extended chassis... Im in no rush just yet to go 8s but i will want to within the next month or so... So ill be patient and see what escs come out. I dont need reverse or motor brakes as my mechanical brakes are so much better and user friendly. Vids coming this afternoon :) |
i wasnt even thinking of driving the car today as it kept on raining on and off but as it was in the boot of the car and a full set of batteries, why the *censored* not...
Ive only run flat grass to make sure it was all put together before trying something a little more stupid... Short vid of jumping on tall grass, mind the driving, still getting used to it in the air.... I also took it out one more tonight on some gravel and dirt... too dark to get videos, but its 100X better and way more fun on these surfaces. Just need to find more areas which are disused... Will be updated with vids frequently when i can find better bashing spots. Thought i would also mention that temperatures are still cool to very cool... averaging 30-50degrees c... No damage was caused in the most recent videos... But after running this evening, i blew one of my dirt claws on grass whilst the truck was driving on two wheels... So frustrating!!! http://www.youtube.com/watch?v=wXsXbNZXwSI and my first vid of the car running now on youtube... better than photobucket... http://www.youtube.com/watch?v=-MsiR0mF2oc |
Its got TONS of zip! Its flying instantly! The temps sound great, sorry about the ripped tire! I would wait for the castle HV like Neil said.
|
im looking forward to the castle HV... do we know when its going to be around? Is this HV specific for cars? its not like their plane or boat ones?

With Savage flux, bulletproof diff 9/29, 44 spur and 21 pinion, the total ratio is 14.95606 : 1, not 10.37465 : 1 (definitely too high). Specifically: - pinion-to-spur (44/21) = 2.09 - first tranny reduction (44/18) = 2.44 - second tranny reduction (29/32) = 0.91 - total = 14.95606 Bye. |
im not running 44/21 anymore... im running 47/18... top speed is 53mph and after 20mins of hard bashing im getting temps of 100-120max

Using the Top Speed Calculator with 47/18, You get a max speed of 36.85 mph (a bit more if You assume Lipo at max charge of 4.2 volts per cell), not 53mph. Bye. |
awww. but you have probably forgotten to take into account tht i am using the flux high speed idler which essentially locks the tranny in second gear... Instead of using the savage flux tranny use the savage x 2nd gear

The Castle HV controller will be car- specific ( or truck I suppose ), and will have brakes and reverse. If you really arent worried about that, then I'd say pickup one of their current ICE HV controllers, or for a cheaper option their is that hobbyking 200amp monster controller ( and numerous similar boat or plane escs ). The only trouble with alot of those kind of escs is that they wont work with pistol radios without a special adaptor called a 'Pistix'- it converts the throttle signal into something the esc can interpret ( since boats/ planes dont have reverse normally, but a car does, so the signal a pistol radio sends out is different to that of a stick radio ).
|
has anyone seen what the new truck specific esc will look like??? maybe they will have a built in cooling fan??? If so i woldnt mind waiting... Are there any pics of them?
|
here is a quick run on dirt... I was using my dish rims for this and dirt bonz
http://www.youtube.com/watch?v=fh7-wU71z-w after this vid i caught a bit of air, cartwheeled and stripped m y plastic servo horn, i have an alloy one on there now |
I found some more dirt places to run, and the truck is getting run hard...
Blew anotehr tire yesterday! THIS IS SO ANNOYING! first my dirt claws now my dirt bonz... so 2 pairs of tires now useless! Back on stock for the time being... cant decide what new tires to get. Also has anyone got any tips for keeping dirt and dust out of the esc? im worried about rocks etc getting in there! but i dont want to restrict air flow |
