thanks for the reply, I think the hyper st is a much lighter car still than the muggy but will start around 15 or 16 and see how it goes, diff wise i'm still debating locking the centre diff as i have done that on my hyper but will keep those rough figures in mind. As far as taping my tyres goes I think i'll probably destroy what I have since they are already use + glued and then tape any future replacements. Got a couple of weeks to work these things out I think before my mount and receiver box comes from the states.

Hi all, I recently got a Muggy roller and want to do a brushless conversion my diffs are 45/11 with aluminium lst cases and my center diff spur is a 46 tooth, probably gonna run stock wheels or atleast around that size. I have an rcmonster mount on order and already have some electrics from my hyper-E, which are a hobbyking 150A 2-6s esc and a leopard 4282 2000kv motor which pulled like a train in my hyper but obviously that is much lighter, will the 4282 be enough for a muggy or should i try and track down something beefier? looking for decent acceleration as well as good top speeds on 4s and lunacy on 6s. If that motor will do me then where should i start pinion wise? Any other advice welcome Thanks Smithy

I am planning to convert my muggy to brushless and need a mount, I like the look of the RCM mounts bt thought i'd ask here first. let me know thanks, smithy

Seems I am unable to PM you, maybe your inbox is full? What hex's are the bow ties and what is the general condition of the tyres, wheels hex's etc? Thanks Smithy

This was a while ago now, the system has been totally upgraded since then. New specs cpu: i5 3570k motherboard: msi z77a-g45 memory: avexir core blue 8gb 1600MHz gpu: powercolor hd7870 xt tahiti le myst edition storage: hitachi 1tb, western digital caviar black 1tb, sandisk 128gb ssd case: fractal design arc midi r2 psu: thermaltake evo blue 650w cpu cooler: arctic cooling freever xtreme rev 2.0 I'm pretty pleased with it now.

Actually it doesn't quite work out like that. think of it like an electrical circuit. two cells/engines in parallel gives the same voltage/rpm as one but twice the current/torque. essentially the idea is you run twice the horsepower and then add on some ridiculous gearing. also something i think nitroholic missed on the pictures is the engine mounts are already there, and those engines look amazing like that. If it were me though i'd be a bit anal about it, they would have to be exactly the same right down to the rubbers on the throttle slider and certainly the heat sinks. whats the plan for the rear tower? is that just a prototype part to be machined with aluminium later or is it strong enough as is? cant wait to see this done, it should be a real handful and drink fuel

the project isnt about the physics or the mathematics, it's purely about the program. I know the basic formula for calculating how long a battery will last given a constant power draw but in an rc it isnt constant is it? like for example the max current draw is i assume setting off from a stand still and minimum should be at top speed/full rpm. so i mean is there like an accepted average for a percentage of power of a motor used?

as the title says, i know the final value of a thing like this is never going to be 100% accurate because of the way people drive etc. but is there a way to do it using maths and some basic assumptions like average power use and things. I know a lot of people say that run time is 20 - 30 mins with a 5000mah lipo in a 1/8th system but i guess that's based on experience not maths. any calculation i have done has left me with a very very short run time but that was using max motor power which simply isnt the case. the acceleration might be a bit harder to determine but lets just assume that we have 100% grip and no air resistance. the reason i want to do this is that i am writing a small program that can calculate things like run times, acceleration, top speeds etc and store the variables for later modification. it may or may not be useful to anybody in the hobby but ahwell its for a computing project at school. so if anybody knows a way to calculate these figures it would be of great help if you could tell me how to do it, doesnt matter how complicated or easy it is, once i write it into my program it will just be a button anyway. thanks, smithy

bump, any offers?

you would have to include quite a lot of bacon rolls too for that to be a done deal bump
