IMO you'd be much better off going for hardened steel diff shafts than Ti ones.

 

The only advantage that Ti has in this application is that it's lighter (about 60% of the weight of steel), which won't make much difference as it's such a small amount of the material, unless you're trying to save fractions of a gram!

 

The biggy for this job is that Ti isn't as hard wearing as steel, especially when rubbing against other bits of metal. So, in a diff, where the gears revolve on its surface, it won't do as well.

No worries pal

 

Had to stop myself from launching into a rant about other material properties to bore everyone to sleep with there...

 

That last vid looked great btw

You'd better have a video camera handy! And no more of this "you'll get what you're given!" talk!

Where exactly is this Seven Sisters bash? Big meet or just a local regular meet?

[Toxic Basher]

Local meet but it's not been so regular with the weather we've had

Ill have my gopro ready for the next bash

Tell me about it! I'm fed up with the weather. You get a few sunny days towards the end of the week, so you start planning for a weekends bashing, then it tips it down all over your parade!

Yay for the UK!

[Scott34]

TB, where did you get your esc/ motor combo from mate? i've seen it about with different size motors, from different countries, at different prices. how much should i be expecting to pay? 

 

Scott

[Toxic Basher]

The esc was an eBay USA job. 130 including delivery and import fees etc it's a beauty of an esc, the data loggings good and allows you to check exactly what's happened each run the motor I got from bez I think. It's a Traxxas xo1 motor. Same as the discontinued castle 1717 but more efficient. I paid around

[Scott34]

have you had a chance to run the 'Savage Hi-Bred' yet TB'? is the motor holding up? i mean, no movement from the 2 bolts holding it onto the centre kit.

 

have you invaded your bank account and done anymore work to it?

[Toxic Basher]

Unfortunately bud the weathers been awful and I'm working this weekend but hopefully ill be taking it out Sunday afternoon with the north west bashers

I've just raided the PayPal funds for new bits for my other savvy and the losi xxl monster

i know, whether wise, its been awful, although i got my diff this morning and by time i got it fixed the sun was beaming , and it went for the whole of my 3s and then my 2s without any issues. i'm proud to own a savage again now . 

now...... on to alza racing,lol, i think i may be aloud a few more parcels  . think i'll get it all extended before i buy a new esc/motor

 

hope it goes well for you at the weekend bud. i think i might travel to orton bmx track sometime over the weekend

if you havent already got the xl chassis and brace kit shoot me a pm

[Scott34]

Corb's, thanks for the offer mate , but i'll be getting the 5t chassis. and with the basket i have ready to buy alza racing have a deal on when you reach 'X' amount with free delivery. thanks for the offer tho bud

[Mr. Doktor]

a 5t chassis will make your savage less reliable and less durable

[Toxic Basher]

Okay guys the go pro is charged and lipos ready, ill be taking this along to 3 sisters tomorrow for an intensive bashing

[Toxic Basher]

well the bashing started good but never lasted, an xl axle gave up the ghost before id run my first packs through it, i have spares but stupidly never packed them   anyway ive got a 3 min + vid uploading now should be ready soon,

im a bit confused with the system though, i was running a 25t pinion on 4s the other week and it got quite warm but nothing major, i geared it down to a 20t as i was going for 6s but i only managed 4s before the axle broke, it was quite hot weather wise yesterday but just on 4s with the 20t pinion the esc and motor were hot too touch, i never even had my temp gun  ill be plugging it into the computer later and pretending i know what all the graphs mean 

[Mr. Doktor]

you have a heavy truck and the 1717 is not almighty, that is all. I have the 1520, which is roughly comparable in terms of power( yes I know the 1717 is stronger, but not much stronger than the 1520), and my gearing standard is always 60km/h on 4s. no temp issues whatsoever and still enough speed. Your current gearing is 102 km/h or so, so do not expect low temperatures. I would change gearing from 20/48 to 16/48. Your esc can handle 8s lipo, so dont be afraid to go even lower on the pinion. Spare the big pinions for speed records and bash with lower gearing 

[Toxic Basher]

Thanks mr doktor I'm in the shed now fixing the axle and will be fitting a 16t pinion whilst I'm here

[Mr. Doktor]

I would also try a 15t pinion. If the esc and motor were too hot after just 3 min of bashing maybe even 16/48 is bit high.

[Toxic Basher]

no in all fairness it was around 15 mins but only 3 mins of footage worth lookin at 

 

[Mr. Doktor]

15? That sounds much better. Now it is time to do some proper testing with the new gearing!

[Toxic Basher]

Well the axles not been fixed but I've stuck a 16t on and gave it a dusting off, ill fix the axle through the week before next weeks run

[Corbs10]

looking good mate looks like it runs quiet well
