How far did you get with that? the motor looks so small on the frame, does it really have enough power? if so, facinating. I'm little more reassured about my project. i'm using 9:72 ratio, hoping this will be enough reduction to give solid acceleration.

So I've finaly made an order for electric parts, motor, esc, batterries. The rear sprocket has already arrived with the chain and i'm waiting on the motor sprocket to come today/tomorrow. I've picked the rear sprocket with 24mm internal diameter, this is just a tad larger than the bearing. it...

I can't make up my mind on whether to go for 6s or 8s setup... 6s is tempting, but worried that it may not be powerful enough

That's actually very reassuring, thanks! What are your thoughts on this: http://www.hobbyking.com/hobbyking/store/__45162__Turnigy_Trackstar_1_5th_Scale_Sensorless_200amp_8s_Opto_Car_ESC_UK_Warehouse_.html I know it's an overkil, but the price is amazing and it is available in UK (faster...

I'm aware about the EM brake. I was a little worried that it may get damaged when for example going downhill and the motor starts generating. There is no freewheel. That kind of scenario is non-existent in aircrafts. If i remember correctly, you do run a freewheel, right?

I've just ordered the motor, batteries and few bits and pieces from hobbyking. went with NTM 260kv motor. The UK warehouse doesn't have any suitable ESC, so that will be part of a separate order. I'm little concerned about using aero ESC in this application because of lack of airflow over the...

BoM so far: Motor - NTM Prop Drive 50-60 270KV / 2400W £23.39 Battery -Turnigy 5000mAh 4S 20C Lipo Pack 2x £21.77 ESC - AeroStar Advance 120A £63.02 UBEC - Turnigy 5A SBEC £3.99 ServoTester - Turnigy Servo Tester £3.95 Rear Sprocket - 72t 6mm Sprocket £3.99 Front Sprocket - 9t 6mm sprocket...

Guess you have one similar to this?: http://www.hobbyking.com/hobbyking/store/__64656__AeroStar_Advance_120A_ESC_Opto.html the price difference is not as much as I first thought. I might go for this, specially since you said the 70A can be burnt. I'd rather pay few quid extra now and not worry...

Wow, the VESC feature list looks impressive! Depending on the cost, I would be most interested in getting one. Failing that, this off-the-shelf esc looks nice: http://www.hobbyking.com/hobbyking/store/__4691__TURNIGY_Sentilon100A_HV_5_12S_BESC_Ver4_.html (not sure what BESC means) none of...

I would also be very interested in buying one. The feature list is incredible.

I was thinking of using Arduino to generate PWM signal. Simply because I can manufacture my own throttle handle and hook it up. If I find an ESC that has telemetry output that could be parsed in Arduino, it would be even better. Oxelo presented an interesting electric scooter where you have no...

Preliminary equipment shortlist: Motor: NTM Prop Drive 50-60 270KV / 2400W Reason: 30V working voltage. this will allow me to have 2 4s packs in parallel. they fit nicely on the scooter underside. Batteries: Turnigy 5000mAh 4S 20C Lipo Pack Reason: perfect size to fit under the scooter body...

great, then I won't bother with the freewheel for the first build. This means that I have sources for all the parts and can start planning the motor mounting bracket. I'll order the 72t rear sprocket today. If it fits well, will get the rest of the equipment.

My main concern with gear ratios is that the motor will not have enough power to accelerate. Does your start from stop? How do you break? It feels that 15-18mph is a good speed. I have found a 72t large sprocket that is much better fit, so I think I'll be going with that, plus there is a...

I am currently looking at 260KV Turnigy Aerodrive motor. It takes 10s to run. Do you have any recommendations on the motor side? I see some turnigy 160kv motors, but the weight is too much! almost 1.3kg! I like Turnigy 6354 primariy because of it's size: it's only 54mm long, it wont stick out...
