Schweizer 300CBI, 269C-1 starter solenoid problem

Sun, 09 Feb 2025 17:03:22 +0000

I recently blew out my starter and the solenoid seemed to be welded closed. So we replaced both the starter and the solenoid. I worked once. But when I went to start it up the other day. The solenoid seems to have welded itself in the on position and I had to shut off the battery. Fortunately the engine didn't start so I didn't blow the starter again. But the solenoid is toast again. I think whatever is causing that might be the issue.

I haven't replaced the "varistor". I am not sure what that does but could a bad varistor cause this problem? the button on the collective switch goes in and out per normal. That switch has not been taken apart yet. I will probably order a new varistor and solenoid.

Does anyone know what the problem could be? Has anyone ever had this issue and solved it before?

Does anybody have an electrical schematic covering the starter wiring? I haven't been able to locate one yet.

Any thoughts on this would be appreciated.

Dynali H3 - pilot reports available?

Thu, 30 Sep 2021 11:08:20 +0000

Hi everyone,

I am in the market for an ultralight helicopter and from the technical specifications and price range a Dynali H3 would suit my needs.

Unfortunately my Google searches fail to find real world pilot reports on this ship. Did any of you guys ever fly one? Or would you know where to get independent information?

unwanted control feedback from cyclic/collective input

Sat, 03 Aug 2019 22:26:07 +0000

B206 experiencing control feedback from inputs with either the cyclic or collective. To be clear when an input is made with the cyclic there is a corresponding control surge on the collective and vice versa. Servos have been checked, pump/reservoir, filter/bypass as well. Control mixer and rod ends checked. Anyone with a similar issue please share the remedy.

From: Looking for partnership / investor

Wed, 18 Apr 2007 19:35:56 +0000

Looking for partnership and/or investor in the building of a Cabin.

The Cabin is self stabilising and manoeuvrable horizontally by a set of small Jet engines
that are controlled by a set of intelligent cameras and a picture processing computer.

The transportation and vertical uplift is provided by Helicopter.

See at: www.olive-eng.co.il

The uses and benefits are endless such as:

Rescue by fast arrival and accessibility without landing in disaster areas, burning buildings...
Maintenance of hard to reach utilities such as Electricity lines, off shore Oil Riggs....
Supplies to boats, military operations.

Most of these applications are IMPOSSIBLE without this type of Cabin - (9/11, floods, Earthquakes)

We can be also contacted by email: avi.eder@gmail.com

I must also mention (sorry I didn't before - because I am new at this) that the idea of
"picture processing" and the automatic operation of 16 small jet engines to achieve stability and/or
pin-point placement of the cabin in space, is a verified technology.
This application of that technology is currently under our patent worldwide.

We are looking for the manufacture, verification testing and application of this cabin.

For further information, cost estimation and project schedules pleas contact us as mentioned above.

Also, if you have other ideas about such a project please feel free to comment on this forum.

Hughes 500C

Fri, 06 Apr 2018 18:20:35 +0000

Hey, anyone out there in the Hughes/MD 500 line ever fly with the Tech-Tool "Cabin Comfort" door windows? I need to replace the pilot side and was wondering if they are liked/disliked. I am 6'-4" so have to bend over to see out as it is, was wondering if there is significant distortion. But having a bit more elbow room would be nice. Also how would it look/perform on only one side of the ship, should I replace the right side passenger too?

Economic machine for heli-taxi operation

Sun, 22 Nov 2015 01:06:13 +0000

Hi All,

I am exploring options to decide on machine that can be used for intra-city heli taxi services.

To maintain affordability, following are the flight patterns:

1) 15 mins return hauls

2) 4 trips an hour

3) 6 hrs of operation every day

4) 300 days of operation a year.

This will equate to 1000 hours of flight hours a year.

I am very much interested to know

1) is 1000 hrs of flight time/annum achievable (availability and utilisation)?

2) which will be the best suited helicopter for this application

3) what other implications can such high flight hours have?

Thanks

Pilot Job Opportunities Around the World?

Fri, 13 Apr 2007 16:35:52 +0000

Okay, third time's a charm I hope. (I tried posting this yesterday twice but neither of them showed up.)

I want to be a helicopter pilot. I'm single, have no kids, and am willing (eager, in fact) to travel. To other countries if the opportunity arises. I'd love to fly helicopters in the bush in Africa, Asia and the South Pacific.

How many jobs are available in places like this? I'm willing to go anywhere, so long as there's a job to be done.

Okay, something weird is going on. I was in the Career forum when I wrote this but now it's here, and my posts weren't showing up at all yesterday.

Is there a moderator around please?

AS350B3 Throttle slop/play

Fri, 15 Oct 2010 16:46:43 +0000

B3 Drivers,

We have been getting some play in our throttles, enough play that requires reaching over the left seat to roll the left throttle to get the amber gov and twist grip light to go out when going from idle to flight. Now when we use our throttle to go to idle the ng will go as low as 64%. We have heard it could be a matter of rigging the throttles and or replacing worn parts in the throttles. Has anyone encountered this problem and if so what did it take to remedy the issue? Looks like several possible parts that could be worn enough to cause the slop. If you replaced any of these to resolve the problem which parts were they?

Thanks
