Nice Video :)

i converted a 950 to brushless using 6s1p fepo packs and a no name 1800kv motor.
because i am a lazy guy i used the conversion kit ... i tried to use the teknorc clutch adapter, but i won't fit :( so i have only 1gear ...

but at the moment i am still working on a battery :whistle:

Got any pics??

I just finished making some modifications to a new body shell. It's now off to be painted. I will post up some new pics when it's done.

Unfortunaly this conersion replaces the 2 gear setup. I think it would be possible to restore the original setup, but then i would have to use a servo to brake ;)

does anyone make a conversion? if so where do i get it?

The motor mount looks like a Speed Pasion and Stormer hobby has them instock for the Serpent 960.This is going to be my next project and need to know if my Neu 1512/1.5/f will fit in a 960 conversion motor mount.Also what is the best battery configuration?:whip:

mabu 01.26.2009 04:52 AM

yes, the motor mount is the speedpassion conversion set.

my configuration will be about 35.000rpm - that would be 5s Lipo or 6s Fepo with the neu.

strodedawg 01.26.2009 09:53 AM

does this motor mount fit anyother chassis in the serpent line? how about the mugens?
thanks

mabu 01.26.2009 10:03 AM

well, it fits in 950 and 960 ... because its developed for serpent, i guess it only fits serpent line - and which chassis i do not know ..may be you get some information at speedpassion.

strodedawg 01.26.2009 11:01 AM

i can get a 950r cheap, that is why i asked sweet! for my 1/8 offroads i try to keep the rpm between 35-37k max. for onroad, since there is no jumps and usually level ground can we up the rpms to around 40k? i would like to run an 8s pack and a 1300 kv motor, what capacity are we looking at 3000? or do i need more?
thanks

mabu 01.26.2009 12:05 PM

i am running a 1515 3d on 6 to 10s Fepo in a 1:8 Xray Buggy and get peaks on maximal 50 amps ( i am using a jazz 55-10-32 ).

so i think you can expect similar ampere here. i did not run my conversion until now because i have to replace the steering arm first :whistle:

The only problem now remained is the motor selection....

:oh:

tested that 19T P / 45T S gives 96deg cel. of motor, ESC is around 45Deg. cel.

Motor is 2350kv with 4S Lipo .... rotor broke ...

Thinking if it help....to use 2100kv motor to lower down motor temperature to around 70deg cel., anyone can give me a hand.....

Countryhick 02.16.2009 04:38 PM

Looks great!!! I think you might want a better quality motor. Maybe try a NEU??
Well done!!

Cheers Andrew

Thanks .. Andrew..

yes exactly ... I really need a serious motor... but in Hong Kong, it is hardly to find....finally yesteraday I got Losi Xcelorin 2100kv for my second trial.

And I will still keep the gear 19T p / 45T s and see how will the temperature of motor be...

May I know your motor spec (kv) and temperature after a continuous run? and how you compare 2gears system vs single gear system in 960 brushless conversion...in terms of motor temperature, acceleration and run time? as I still unsure if it need 2gears system for brushless... to achieve a comparable speed with other Gas Power 960. But seems now just use 2nd gear gives motor too much loading and temperature...( at least with cheap motor, hope Losi 2100kv works better)

I'm using a NEU 1512 2050Kv. (but I run 6s LiPo) I think your motor KV will be a little low to achieve the same speed as a gas 1/8th, unless you can drastically gear up, which will possibly add to your overheating issues.

Because I use a large aluminum motor mount, the chassis of the car dissipates a lot of heat (this is how the gas motors also dissipate their heat) running temps are around 70deg C. (30deg ambient) This reading is after continuous running on the racetrack for 10 Mins. I see you have a CF motor mount and this could partly be some of your problem.

After running the car with a 2 speed, I don't feel that there are really any benefits. If there was a larger ratio change between first and second then there maybe an advantage.

Because I haven't tested with a single speed I can't definitively state if the run time is better or worse. I do however think there wouldn't be much difference.

Keep us posted!! It's great to see these 1/8 onroad cars popping up :yes:

Cheers Andrew

Capricorn RC Serpent 960 EP Conversion update 2
 
From Red RC

A 2 speed with no mechanical brake? I'm assuming its not completed yet.
