Thanks for the replies, is the Savox 0252 a staight swap in with the installed servo saver, I like the idea of this as the Buggy will be used for bashing and its metal geared and has 10.5kg of torque. Mark

Hi, Got a Bullet ST Flux on the way and have ordered a Savox SC0252 Servo for it as I had read the standard servo was a little weak. Is it a straight swap, does the Savox have the same number of teeth as the HPI one or do I need to fit a different part onto the servo? If so are alternatives supplied with the car or will I need to purchase another HPI servo saver, I have looked at the servo saver kit and it appears to have 3 different options for plates to fit on the servo. Also has anyone exchanged the radio for a 2.4 system, I have looked at the systems from Hobbyking, Hobby Partz and Etronics, apparently cheap but well specified, has anyone had any compatibility problems with the esc etc? Thanks Mark

Hi, looking to get a 2.4 radio to replace the standard on in a HPI Bullet. Has anyone done this? What are the results, is it compatible with the esc? I think the Bullet ESC is the 35A Hobbywing one, also does anyone have a link to the instructions for them. Would I be better off getting something like a Spektrum dx3e at 3x the price? Mark

Hi, was wondering what the max size is for the Lipo saddle packs to go in a team associated B44.1, the reedy packs are 69.5x47x25.1 but are expensive when compared to the Zippy flightmax (about 1/4 the price) but the zippy flightmax is 69x46x31, so approx 6mm taller. Hence the question what size pack will the B44.1 take, what are the max dimensions. Thanks Mark

What are the dimensions of the battery tray/box on the HPI Bullet so I can get the max capacity 2s battery in it? Thanks Mark

Jony Nitro, Thanks, I have a Fastener shop nearby so I was planning on visiting them today, but if I have no luck I'll PM you. Thanks again. Does anyone know if a countersunk washer is available to increase the head size of a 3mm countersunk bolt to a 4mm countersunk bolt, so that I can increase the area over which the load is spread when I attach my motor? If so what are they called and where are they available from? Regards Mark

None that seem to fit the motor, i guess the Losi Xcelorin motor may have a larger size thread than the Mamba motor?

Hi, I'm currently building and converting a Losi 8 2.0 EU to Brushless using the Losi conversion kit. The motor i am using is a Mamba Monster, this came with screws to mount it which appear to be M3 in size, the heads are standard allen socket heads. The Losi motor mount is machined to take countersunk head bolts and the holes appear larger than M3, can anyone who has installed this conversion please tell me which screws I need and how long they should be? (ideally i do not want to tap out the motor mounting holes as it will affect the warranty). Also good suppliers of said screws would be helpful. Thanks in advance. Regards Mark

Hi, this is the wiring diagram from Castle Creations web site, slightly different to the method used by CB6FS, this one uses the BEC to power the receiver and servo. I think this will help in my case as I want to up the rx voltage to 6V from the 5V supplied by the esc BEC, as well as having the ability to provide a constant 5A supply for the servo, not sure how many amps the on board BEC can supply from the esc. CB6FS did you solder the wires from the BEC to the servo or get a male-male connector? I had not considered wiring it the way your diagram showed. Regards Mark

Thanks for all the input, I know where i'm going with this now, seems a little disappointing though that the esc which is designed for a 1/8th buggy cannot power the receiver and a suitable single servo through its on board bec though. I have seen it mentioned that capacitors can be used to 'stabilise' the voltage, could the SPM1600 Spektrum Receiver Voltage Capacitor be used on Futaba gear and would it be effective or would I be better off going with a BEC? Regards Mark

Does the CC Bec automatically detect the number of cells the car is running on or does this have to be set using the Castlelink as well as the voltage to the rx? Also does anyone know what the current draw of a Savox 1256 is and what servos are others using for steering? Regards Mark

Vorza,thanks for the photos,really helpful, did not realise the CC BEC was so small, so will lend itself to a simple and neat installation. Where did you get yours from? Also does the Castlelink adaptor that comes with the Mamba Monster fit the BEC so that the voltage can be adjusted? CB6FS thanks for your response, I looked at the castlelink software, but the Mamba Monster setup section does not appear to give you the option of increasing the BEC voltage and the instructions say its set at 5V, which seems a little low for an esc designed for a 1/8 vehicle that will be using high torque servos (and high current), maybe there will be a software/firmware fix, but in the meantime I think I will look at getting a CC BEC. Thanks all and Merry Xmas Mark

Hi, I am in the process of sorting out the electrics for my new Losi 8, I have a Mamba Monster esc with 2200kV motor, Futaba 3PM-MX 2.4GHz radio with R603FS receiver, Savox 1256 steering servo (Digital Coreless Motor). I wired up the electrics today to try them out and ran them using a 3s 2500mah 20C lipo (none of the components were under load and the esc was set to auto detect). I will be using a 4s 4500mah 30C battery in the car when it arrives. I bound the Tx and Rx, then calibrated the esc, the motor worked fine (throttle reversed as per instructions), but when I used the steering servo, the movement was slow and jerky, when it went to return, the red light came on on the Rx indicating it had lost its bind and the motor twitched, it then regained it and returned to the normal position, this was tried several times with the same result (using both PPM and HRS modes), an analogue servo was tried in PPM mode and was found to work normally. The instructions that came with the Radio said the Rx required 6V input, the instructions for the esc says that the output to the Rx is 5v and it does not appear to be changeable through the computer interface. Has anyone else experienced this problem, my solution at the moment is to run a receiver battery pack (6V), hopefully there will be space somewhere under the car body. Other possible solutions would be a separate BEC, does anyone use these, any recommendations on make and model? the final option would be a servo with lower current drain, most likely analogue what type do people use? Alternatively does anyone else have any other suggestions for a solution? Regards Mark

Cheers Garry, in that case. i'm probably better sticking with PPM as I'm not that quick!

Tim, thanks for the quick reply, was struggling to find details of the BEC output for the Mamba Monster, but kind of guessed that it should be OK as Castle Creations are an established company as are Futaba. Still not too sure about HRS yet does anyone on here use it? What are the benefits? Regards Mark
