Some inspiration for your build. The body shape is a little different
I disagree about the negative attention, you tend to reap what you sow....
If you have achieved 165, then it's not representative of what others have achieved with similar aerodynamic set ups....
"(more can get hot)"
For 8S you'll need a 40mm motor with 1100-1200 kv (more can get hot) PLUS a suitable ESC with acceptable voltage & amp rating (XL2, MGM etc)
For 6S you'll need a 40mm motor with 1500-1700 kv (more...
Nic has set a faster speed which is currently awaiting GWR endorsement...
The Annihilator is a great build & I’m sure most members enjoy seeing the innovation & commitment associated with these types of builds. In my view they should be celebrated
I’m not directing...
Maybe a few items of benefit here; http://traxxas.com/forums/showthread.php?535111-Building-ideas-for-a-fast-Rustler&highlight=ideas+building
I use BluTack with fine bird shot if required for additional weight
I know a little about lift/negative lift in the general sense & while the OP may know this, people new to these concepts or fast RC may not, maybe my comments will help someone?
I'd just try the front & leave the rear off
Unless you're cornering, you'll only need the front sway bar
If you could fuse a wind tunnel with your dyno you'd have all that data & more
As in theoretic speed? Or can you calibrate dynamic resistance to mimic drag?
The photo & link were just to illustrate another design, it was the first one I found in Google
If you're already running an XL-2 with data logging, what will the dyno give you that the esc won't?
Not Necessarily. Weight can come from negative lift through aerodynamics
If you mean sprung/unstrung weight then this has a relationship with aerodynamics but it doesn't work independently of aero
He was making a funny I do believe. I got it
I'll be disappointed if it's harder to bring the XO-1 up to speed than an over powered 1/10 TC or 2WD that I've had in similar circumstances but I take the comment on board
I'm hoping foams will...
With the amount of power the motor/esc combo can produce I expect to trash the driveline before any amazing speeds are achieved & hopefully the all up weight will help keep it on the ground so I can...
The depreciating purchase price has made an XO-1 experiment more achievable. Having the esc & motor at hand makes it approachable
Will purchase & modify a motor mount, custom gears, custom BSR...
Yes, scaling speed is a calculation derived from the scale. Brian has given a lot to the RC community through his estimators
Over the blue wheel nut
Yep, the laws of physics are easily tricked
What you have quoted here applies to acceleration. Can you find the calculation or descriptive quotes for speed?
Would you believe me if I said I took a standard 1:1 car & shaved a bit of weight...
I would normally wait for a response but I have some time to offer some non-pro racer feedback on your tips;
1) wind resistance in often called drag. To reduce drag you can do a few things & yes...
