Another Revo Build :) 6s 11XL

[Sammus]

Well, got rest of my stuff finally
Am running a converted revo 3.3 with:

RCM mount
Feigao 11XL
Turnigy Sentilon HV ESC
6s (2 x 3s) 4000mah 20C/25C lipo's
CC BEC
Tekno receiver box and throttle(read: brake) servo mount

and thats about it I think.

So basically I just put it all together :P There was like an extra motor support thing in the motor mount package that I have only just realised (as I'm typing... literally) that it must be for the bigger diameter neu motors. That confused me for a bit, not too long though :) Also I'm not real impressed with the tekno throttle servo mount. Like sure its better than the original (Stiffer...) but it doesnt fit properly, the holes to line up perfectly and as a result I ended up with a slightly warped servo mount - the servo still fit in ok though.

My biggest hiccup was when it was all finally hooked up and I blipped the throttle with the wheels off the ground... I had accidently put the front diff in upside lol and the wheels spun in opposite directions :P funny stuff haha. (I'm used to diffs coming out the bottom for some reason, so when the casing read 'revo top this way' or whatever it still didnt help!)

Please note, before you see the pics, this is an extremely dodgy assembly just to see how it goes because I was meant to be busy working

Dodgiest looking of them all (is the shaft of these motors normally that short?):


Home made battery tray out of 50mm equal angle 3mm aluminium


My temporary dodgy attatchment (something a little more robust coming soon I promise )


With the batteries in:


Overall layout:




Now before anyone comments, the esc has a second less visible zip tie to stop it falling off all together :P

The lipos we're fixed on with a few zip ties for their maiden voyage - something definitely has to be fixed there, I did it a bit tight and bent one of my cells :( And I thought vented packs were a good idea hehe.... nothing serious though, just bent it back and its good as new. Will have to get the gf to sew me up some velcro straps for a more snug yet less stressful ride.


Overall I'm not too upset with the balance off the vehicle, will definately work on it soon though, so far the figures are
FL: 1.117kgs (2.463lbs) | FR: 1.085kg (2.392lbs)
RL: 1.32kg (2.91lbs) | RR: 1.423kg (3.137lbs)

Giving a total weight of 4.95kg = 10.91lbs
with a 44.5:55.5 F:R distribution.

I'm pretty happy with that... a bit worried about the FR and RR being the lightest and heaviest corner respectively... I'll have to do something about that.


Anyway, all that rambling done and gone, the thing absolutely hammers! For some reason I wasn't expecting a lot lol. It was gearing 16/38 and would easily lift up in second if you gave it full (didn't get to wind it out, those wheels are way too unbalanced!)

Smooth as butter on the startup front, I can start as slow as I want with absolutely zero sign of any cogging. That said, its almost a little too smooth, it seems to lack the punch that I'm used to from the electric, almost like it has a built in punch control. Probably a good thing for my poor old drivetrain I guess :)

I didn't get to run it longer than about 5 minutes, and it was on asphalt. The batteries didnt get above ambient a the esc and motor I could detect the slightest bit of warmth in - maybe 2c above ambient at a wild guess..

Can't wait to get it on some dirt... I'll add some photos and videos as I refine the vehicle.. and yes I am in he middle of a home made esc mount, that should be not quite as dodgy as the one it has now :)
