Huh, that's cool!!! Has anyone 3D printed a prop yet?

yeah, but I'm sketchy on that.

i'd do it for static scale stuff, but not sure I trust it spinning 10 grand.

the unthinkable has happened.

Hitec 7950 let me down. Won't center, only turns left and then locks there. Wasn't wet inside and some contact cleaner int he pot made no difference. I'm not even sure if they still use a carbon wipe pot or if it's digital encoder.
off to hitec it goes. Sucks, going to take two weeks probably to get a replacement.

I'd killed Hitec's before, but only in the 1/4 scale gas boats I used to race. That is a extreme/harsh environment for anything; I think the heavy vibes mostly did them in....

I really wasn't even bashing.
out for a walk withthe wife and the local park has paved paths. The city basically built me a massive race course

then it just turned full left and stayed there.
It has led a pretty hard life for the last 3 months though. O ring seals were doing their job though. I think maybe the next one I'll take apart and corrosionx right off the bat, just in case.

edit:
build quality was impressive though. The aluminum case fits tightly on the motr and there was even thermal compound between the two. The only let down was hot glue for wire stability and not proper silastic.

so that's what many hours of 3d printing looks like when you put it together.

and yes, the ball bearings are functional, and the 3d printer printed the races and balls at the same time.

I just weighed it.
4lbs 5 oz with everything but the battery.
it's supposed to weigh 2.5kg all up.

it's not so heavy given that it's a 48" biplane.

well I had this thing fixed for a week and life shit all over my free time.

Finally had it out today.
Gyro is awesome. Definitely changed how it drove. It's set pretty low, but it saved me once when it got super wierd speed wobbles after a bump upset the rear end.
XT90's made a noticeable difference in power. Batteries weren't even fresh off the charger and it will ride 35mph wheelies in tall grass now. ESC and everything was cooler. XT60s were much more a limitation than I thought.
Repaired servo seems fine.
Landed two front flips back to back on the gravel pile. Almost have those dialed too. Front flips are way cooler than backflips.

bent a lunsford tie rod.

I was kind of impressed with myself.

Cool you got the gyro working. Those XT90's look comparatively large. I'm fighting the urge to direct wire the B64, but seems to be what all the racers do. I like the convenience of a plug. Where do the standard Dean's stack up against XT60, XT90, etc...? I haven't checked specs in a while. I use to be a Dean's guy for everything, but thinking seems to have shifted on these?

That is impressive! Enough mass and enough speed combined will do that

I'm not a fan of deans because they're such a pain in the dick to deal with on a daily basis.
XT90's are 90A continuous. They make XT 150s.
Deans never really says a current rating.
You might also want to look at the traxxas stuff. It's slimmer, and I think they're rated to something like 100A continuous.
I guess they can be a pain to solder up if you don't get the wire cut just right.
I like the XT connectors because they're easy to solder and don't come undone.
Just make sure you buy Amass ones. The clones suck and use shit plastic. The Amass ones are nylon and they don't melt when you solder them.

took it out to my in laws today for family cookout.
now another lunsford tie rod is bent...

I'm still amazed that 4mm TI is the weak point.

Broke the shit out of body posts. I'm surprised they've made it this far.


Spring cleanup in my town and someone was tossing this kicker. I snatched it up and put some tape over the hole.
no good for skating, but fine for RCs.



but that means i wasn't waiting for parts. i got a sweet ramp and I need to see what's up. Had some scrap PLA, so an 80w chisel tip and some burnt plastic and it's fixed, enough.
