should I convert my savage
 

I have been looking at the hpi savage flux this past week, and I have been thinking of building one myself. I have a nitro savage and a e-savage already so what I have been trying to decide is should I try to convert my nitro savage to a brushless or just start new and build a whole new brushless 1/8 scale savage. what would you guys do?

I'm thinking about converting my savage to a brushless system since I have a feigao brushless motor just collecting dus on teh floor or desk or wherever it gets moved to next. and since I can't get the engine in it to run anyway, I just thought of doing a 1/8 scale brushless. but I have a question. can I gear the motor to have less torque so that I can keep my three speed tranny in the truck for a little while? until the savage flux comes out. and then i can use the tranny from it in my savage. or lock my other two speed tranny?

Gearing doesn't much effect the torque, use lower voltage if plan to have mercy on your tranny. :wink:

I presume that's an XL Feigao you have there, what is it's kv rate?

If you have a second tranny, then why not locking it - then you have reverse plus motor brake, depends from your ESC ofcourse.

the kv rating of my 8xl is 2084kv I think. what would I have to do to lock the savage two speed? do you have a link with pics of what to do?

Actually, gearing does have quite an effect on torque. If the motor has say 0.3 fl-lbs of torque at the shaft for a given amperage, gearing down 20:1 increases the gearing factor, so it's 6ft-lbs of torque. Reducing the gearing (increasing the ratio) increases torque at the wheels.

Oops.. I was thinking of torque that is effecting the transmission, but thanks for correcting me.

does anybody know what I have to do to lock the two speed tranny in second? any pics of it? thanks. also how big of motor will I need?

There's a good thread about this few pages back, http://www.rc-monster.com/forum/showthread.php?t=13587
Scroll down to 9th post for info.

I thought you were using your 8XL Feigao? It should be allright.

If i use the 8xl that I have could I keep the two speed tranny? or would I have issues with it down the road.

Idler & drive gear look slightly stronger on two speed, so it might even hold up.
I hopefully get rid of the transmisson problems when the Kershaw tranny is ready. :yes:

okay thanks janezki, I will give the two speed tranny a try and let you guys know how it works out. thanks again.

I run a two speed in mine with no problem. But i DO HAVE DIFF problen

okay thanks, I guess it might be wise to wait until the savage flux comes out and then maybe I can use the tranny from it in my build.
