Nice Virusss
Could you give us some more details on:
the motor mount
clutch you are using
brake setup, mech, or are you using the motor to break
total weight of the car

virusss 08.29.2009 06:50 PM

Motor mount is made by Serum :) Super nice work
I use the brake stock system (mechanical), with the motor brake the esc make too hot, stop a 11 kg of car is difficult for esc.
i don't use a clutch the pinion is connected directly to the motor shaft

Very interesting browsing your eagletree file. I made a quick sum up graph while zooming into 1 minute of your run (mostly speed runs):

Virusss, do you know your overall gearing? Which pinion size do you run? Judging from rpm and voltage level i suppose you run a Neu 2215 2.5Y (600kv), is this correct?

With 5000mAh and a more constant / agressive power use (especially when running higher output batteries) i would expect runtimes to drop below 10 minutes (more then 500mAh per minute) and an average power of 1KW. You might want to get higher capacity batteries.

Wow Othello, very nice explain my eagle tree file...
yes the neu is 2215 600 kv
the gearing is 17/57 (stock)
my runtime approx 18 minute if i remember correct
i like to try 35c hyperion, and i like to try in offroad

p.s.
i like so much your video with eagletree file in overlay...how did you make?

othello 08.30.2009 05:52 PM

I am using a hyperion G3 3s 2200mAh vz 35C lipo and it performs great in a 1:16 buggy. Built quality seems top. Recharging with 10A (max 5c) takes about 20 minutes. Capacity although is only 2050mAh and not 2200mAh.

I posted some guidelines on how to insert eagletree data into a video about one year ago.

This is my latest video with eagletree inserts featuring my custom 4wd Baja based on 2 1:8 truggy chassis.

very nice guide for video editing :)
next week i try the baja off-road and i make a vid

Hallo boys, i have a problem...
I must protect my 2215 from dust, but I do not know how close the fan that sucks air ...
I had thought of putting a filter but I do not know what
Any ideas??

You might want to try something like this

Stockings/nylons from your girlfriend/mam should do.

And if you want to protect your front bearing from wet cut a round piece of felt, grease it, drill a smal hole trough it and glue/attach it on the front shield right in front of the bearing.

virusss 09.17.2009 05:19 AM

yes othello, i like the collant system :) but in the rear side?

Is it me or does those Bajas move faster then the gas version.

cembom 10.06.2009 02:05 PM

The first one was absolutely silent. But I would like some more details on the second one.

Desert Rc 10.06.2009 04:41 PM

Top speed of his with the same gearing as stock will be a fair bit faster because of the RPMs, but that acceleration is where it's at. The stock tires suck, particularly in grass, but with a gas Baja it's actually somewhat controllable with any significant amount of throttle. That 2215 has plenty of power on tap to do some custom greenskeeping!
