Progress is going well. I have made up some temporary battery trays (I'm going to make the permanent ones from CF) from 3mm alloy, I'm going to take to them with a drill to reduce some weight this weekend. I have attached a pic with the tray and my fake batteries (my 3 X NEU 2S1C 5000 mAh are in the mail) as you can see it looks like the L/R weights should be close. I will know more when the packs arrive.
I have also attached a pic (far left) of my temporary motor mount system (it hasn't been line bored or machined for weight reduction) it is a simple band clamp setup for testing only, the permanent one which I have nearly finished deigning will be CNC'd and include a integrated 12 fin heatsink and will still be a band type clamp. It will use the original 21 size motor mount bolt holes as well. A friend is going to transfer my hard copy to CAD so if anyone in the industry knows what format I need to give the machining shop please let me know. Still waiting on the motor (NEU 1512 1.5y/s) to become available from Mike's shop so I can order the speed control and motor at the same time. Hopefully they arrive soon so I can get this thing up and running. |
If any one has a NEU 1512 1.5y (smooth can) they want to sell please PM me. I will consider a finned can but would prefer smooth as I would have to machine off the fins to have it fit.
I would also consider other NEU 1512 motors around the 2000KV range. Please help as I'm having extraordinary issues trying to get my hands on one of these motors. I even called NEU directly and they are out of stock and expect there to be a six week delay minimum before they have them back in stock. Cheers Andrew |
Just took delivery of my NEU 1512 2.5/D, MGM 16018, 2 speed pinion adapter (thanks Mike) and a few other bits and pieces. I will post some more pics soon, hopfully have it running in some form by the weekend. :party:

Nice setup. I went racing on the weekend and was surprised at how well my brushless mini-t could keep up against the 1/10th scale tourers. They were flogging me due to my inability to keep it pointed in the right direction but it wasn't that much slower then them when I did keep it on the track. It was great fun though. I'm keen to go road racing again now.

I can't believe it. I just received my MGM 16018 speed control and I'm having trouble programming the basic transmitter setup. I have a Futaba 3PK radio and use a Futaba R203HF HRS receiver.
I have tried all the suggestions I can find and still nothing. I can report that when in HRS mode the motor will continuous beep...beep...beep etc after holding full throttle and the switching on the speed control. I have tried reversing the channel but still get the same response. When I switch to either PPM or PCM mode I get no recognition from the speed control or motor. I have tried reversing the throttle channel in all modes and still nothing. I have even tried to on hold the throttle on just slightly to see if it makes a difference and nothing happens, no beeps, nothing.... :neutral: Maybe I should find a standard (non HRS) receiver and try it. (wish there was a crying smiley) |
Just tried my old JR XR3 radio and it programmed it fine. Might send this one back to MGM and have them install the latest firmware. Another set back urrrgghhh. :cry:

Gave my car a shakedown run today. Very promising results. I will post pics and maybe a vid over the next few days. I should also have some data from the eagle tree data logger for viewing also.

Got a small vid of it's second shakedown run.

man that thing has some spunk.
|
Damn.... Wont be long before that is the standard and the nitros are second class racing.
Nice job. |
Damn!! That thing rips! Nice job on the conversion btw.

Just wanted to say thanks to the guys who have given me advice on this forum, I couldn't be happier with the results and would of ended up wasting a heap of money without you. Next stage is to reduce weight and make things look prettier. :lol:
I will get some more footage and take some pics this week. Here is my setup so far CAR: Serpent 950 MOTOR: NEU 1512 2.5D/S (2000 Kv.) SPEED CONTROL: MGM 16018 BATTERIES: 3 X NEU 5000Mah (6s) GEARING: (1st gear 20t P / 48t S) (2nd gear 23t P / 45tS) BRAKE: Mechanical (standard setup) |
Please do post the pictures. I for one would really like to see them.
|
That's pretty damn quick. Have you gotten to see how it compares to some of those noisy cars?
