Description

Not another Heli launcher! But this one is different, it features an 1:9 gear System for full Power supportet by 608 ball bearings.

External Hardware:

Assembly

Press Bearing

Press a 608 bearing into the hole of the middle housing. This is a tight fit, so you can use a hammer or a vice. The bearing won't slip in all the way and is about 1mm proud

Gear Assembly
Follow this guide step by step, otherwise you won't be able to get the "Counterpart in"
press the bearing into the 30 teeth gear on the 20/30 combination gear. Don't press the other bearing in yet
2. Add the shaft gear into the already pressed bearing
3. Add in the screw and the counterpart from the other side. It should be tight with no wobble. Sand if necessary
Assembled Shaft.
4. Now you can press the other bearing into the other side of the shaft assembly
5. Press the bearing into the 10/30 Gear
6. Put the two gears together like shown
7. Put the whole assembly into the midle box
8. While holding the gears in place, screw in the M3x10mm screw from the other side. This will widen the shaft and hold the Gears in place.
9. To make the gears last longer, you can add some lube

Final Assembly
Screw the remaining parts together and you are done!

Great model!! I didn't have any bearings laying around so I printed some from maker world. https://makerworld.com/en/models/396617?from=search#profileId-297924 Your model worked excellent even with printed bearings. I didn't even have to screw it together initially. stock rotors fly good, would like to see a few Toroidal rotors for this thing, they would really go great. Thanks and keep up the good work!

@SOLIDIZER

we printed bearing for fidget spinners. that how we ended up here lol

@user_338778319

Hi, I just have a question. I printed the same bearings and when I pull the rod out of the launcher it usually gets stuck. I was just wondering if this ever happened to you or if it's just a problem with mine.

@teobabaisko

which model do you print

Really well made robust design! Printed glow in the dark props that made it even more fun in the night. Nighttime pic is taken with long exposure.

Looks nice 👍 Thx 😉

@user_2697987610

glow in the dark is such a great idea

print came out great but doesn't fly that much. I expected that a 'overpowered' thing would fly a lot more

@laisch

Hi, looks like you printed it on an A1Mini? The smaller pull handle which I added to make it printable on smaller build plates does not provide as much power as the long version. Maybe I will try to come up with a "glue together: version of the handle for the A1 users which provides the full stroke length.

@beaver1000

Replying to @laisch :

You might try and design the pull to curve around the build plate. If that works, maybe coil it up like a snake to make it even longer.

@laisch

Replying to @beaver1000 :

This could work, but then it has to be printed in TPU for flexibility.

The holes for press-fitting the threads need more material. The four threads used to attach the lid with the logo are being pushed out (see photos). In one hole, this even prevents the screw from passing through due to the offset. On the other side, the lid is warping. The lower four are not as problematic, although the “puller” moves along a bulge. The single thread in the upper gearbox attachment is also fine. (Printed with Eryone Crystal PETG blue, red and grey) I am currently reprinting this housing part and hope it will be somewhat better with the press-fitting on the next attempt

Okay, a new print and inserts one size smaller already looks better The inserts on the long side still bulge slightly, but if you press them flat while still hot, for example with a blade, that's fine M3 6 x 5 seems a bit too large, M3 5.5 x 4.5 works then Where to get M3 6 x 4.8 is still unclear to me Okay, now I'm still waiting for the set of M3 countersunk screws, as I only have round-head screws so far It will probably continue tomorrow

Brilliant little copter, my relative's children will have lots of fun with these.I have made four, 2 from pla with PETG gears, and two from ASA for the older boys. Well engineered and so easy to assemble.Thank you so much.
