BL-Revo,

How many mounting screws does the non-ultimate RCPD tray use? I have the RCPD Ultimate for my E8ight, but it is pretty heavy. I'd like to find something lighter, so I tried the RCM tray, but it only covers 2 of the motor mount screws, which I do not think is enough.

Thanks,

do you mean the battery tray? it uses the 4 engine mount screws that's it :)

does anyone know where to buy an adaptor so i can balance charge my 2 2s lipos at the same time? i have a series adaptor for the deans plugs but don't know where/how to make the balance plug?

thanks richard

Hobbycity.com has some adapters that'll allow you to do that. Pretty sure you have to be careful how you hook them up but they should work. I just use 2 balancers

i had a look on the website but i can't find any adaptors that do 2 2s's just 2 3s's????

Interesting...I could've sworn they had a good assortment of them last I checked. I looked again and all I could find was the 2x3 one.

i missed the best deal on ebay last night a Neu 2050KV motor went for $99.99
anyway i am still on the lookout for one of these balance lead converters as i have looked all over the hobbycity website and came up with nothing

right i have had enough with the temperature of the motor
it is getting too hot for me and the runtimes aren't up to much either
if i was to go for the 2650kv MMM combo would i see quite a big increase in runtime?
also is it ok to run the mamba monster combo on 4s 4000mah 25C lipos like these:
http://cgi.ebay.co.uk/RC-Helicopter-...1%7C240%3A1318
or would i need a battery that could deliver more Amps?
if i was to keep my mamba max and just buy a motor would the temperature of the esc go down because i have gone from a 9xl motor to a more efficient motor?
will 4s be plenty on a 2000kv motor or would i just need to gear it up a bit?

thanks richard

I've never seen that brand of lipo before so I wouldn't trust it. I have a NeuEnergy 5s 3900 mah pack that is good enough to handle the current that the 2650 draws. A 3900 mah 4s pack is 95 USD so i would go with that. I can easily drain my 4s 4100mAh 30c pack in 12 minutes. I basically found that the 2650 is a very versatile motor on 4s (stays fairly cool w/ various gearing) gets a little warm in a tight space on 5s and runs cool and in a wide open space on 5s and is rediculously fast!

i was having a bit of a think and surely the motor should be run cooler in the buggy than my old revo? i used to have the revo geared on 40/16 and the motor was quite hot to the touch but no where near what it is in the buggy
the buggy geared with the stock spur and 16t pinion means the motor gets very hot. i was wondering if there was any binding but all the wheels seem to run smoothly and it free wheels for a long time on road?

what would be the signs for binding ?

[SpEEdyBL]

Take the motor out and spin the drivetrain. It should continue spinning for several seconds. Buggies can handle more power than MT's just because they are easier to drive fast. It takes about power to push me 7 mph on a scooter than it does to push my 8ight 35 mph, so gearing down is certainly easier on a motor than reducing the same amount of weight ratio wise.

what would a 3300kv motor be like? and is a 1509 too small in the 2700kv version?

Are these motors for your 8B? A 3300kv on 4S would not be difficult to drive in any race application, use a lot of mah, and run hot. If you are using a 1512 sized motor most are using the 2050 on 4S. A few have tried the 1509 in a buggy, but no one is saying it is the best option. If you do go with a 1509 I'd go really low kv (1450) and 6S. This should keep the heat down in a 1509.

i think i am going to get a 2200kv 1515 motor for now since i will be mainly bashing

That will be plenty of power for bashing. My buddy runs that combo in is Losi 8T on 4S and it is very powerfull. It seems to have more punch than my 8B (MMM, Medusa 60x2000, 4S), but my buggy gets better traction and thus jumps a bit farther at the track. That motor in a buggy should be able to be geared pretty tall without heat issues. I'm guessing 45-50mph.
