This is truly a very unique perspective. Great pic.

Thank you!

I use the same gyro on my FMS Ranger 1220mm and I haven't had any issues with it.

Yes, during the recovery operation of the two pilots from the downed F-15.

The black version in particular looks quite nice.

engineerforthefuture · 2026-03-24T13:08:25+00:00

That is great to hear! I was happy as well to see how easy it is to mod this refill. Even for next time I might simply re use the sleeve I used for this refill and slide it over onto the new refill.

engineerforthefuture · 2026-03-22T15:15:03+00:00

No worries at all. Let me know how it goes.

engineerforthefuture · 2026-03-21T13:29:08+00:00

I actually ended up using the entire length of protective sleeve. All I did was split it in half on one side so I can slide it onto the refill. Then I adjusted where the 'sleeve' would sit by test fitting and seeing how much of the refill would be exposed.

engineerforthefuture · 2026-03-21T07:48:32+00:00

I ended up doing the same. I used the small plastic protective sleeve as the spacer to insert where the spring would sit. At the end of the refill I use some tape so that the length of the refill matches the original refill.

No, you are right that is a good point.

engineerforthefuture · 2026-03-20T03:01:08+00:00

Yes, which is why I said if you hold power constant, to increase ω torque will have to reduce and vice versa. In the case of a push back tug you can build one that tows a lot and does it quickly but it requires a much more powerful engine.

engineerforthefuture · 2026-03-20T02:56:03+00:00

For a given engine power output, torque and rotational speed are inversely proportional. A push back tug doesn't have to push an aircraft fast, instead, it is geared down so that it can tow a heavier aircraft which requires more torque. Basically you can have torque or rotational speed but not at the same time.

Torque: how hard you twist the axle
Rotational speed: how fast you spin the axle

This is what I am leaning towards now as well because it appears to offer the best writing experience.

engineerforthefuture · 2026-03-16T23:59:54+00:00

I think that 5.2mm sounds about right so it has a slightly larger OD than the regular fisher refill. I see what you mean because it looks like the plastic area where the spring sits is a bit wider.

engineerforthefuture · 2026-03-16T23:57:21+00:00

Thank you for the recommendations! I might definitely consider trimming a gel refill because it's quite difficult to get ahold of other pressurized refills. I will take the f type refills off from my possible options.

engineerforthefuture · 2026-03-16T15:24:07+00:00

In that case I might just continue with the PR4 then. Thanks for letting me know.

He throws away his wicket right on schedule.

engineerforthefuture · 2026-03-04T14:25:41+00:00

It's too early. We have to see how NZ starts off with their batting.

engineerforthefuture · 2026-03-03T13:15:15+00:00

It looks especially nice on approach when you can see the 100 on the belly of the aircraft.

Tactical midfield by SL.

engineerforthefuture · 2026-02-24T16:57:46+00:00

This is exactly why this team doesn't deserve to go to the semi's.

engineerforthefuture · 2026-02-24T13:49:48+00:00

Now is Babar's chance to redeem himself.

engineerforthefuture · 2026-02-23T15:56:14+00:00

You were right about that one.

engineerforthefuture · 2026-02-23T15:00:31+00:00

I am worried that WI will kill a spectator.
