That’s awesome. I have actually flown a machine with just an airspeed indicator and slip string. That’s it. It was unnerving and I flew rather high without an altimeter.I can install a short rod in the top of the pod for a string. The right instrument has a slip indicator at the bottom too.

It will for sure but it will still funk out from time to time. Are you using a separate AHRS sensor mounted remotely feeding this Infinity or is it built in version? If you are using SP-7 remotely mounted and if you mounted it in a good location that may work much better. The iEFIS with built-in sensor has no chanceI hope that the three rubber mounts that the pod is on would help with those vibrations. Ill install a string.
My first solo forays on a Bensen were with ASI, ALT, and string, not quite as limited, pretty basic, but enough.That’s awesome. I have actually flown a machine with just an airspeed indicator and slip string. That’s it. It was unnerving and I flew rather high without an altimeter.
I am just wondering, if the Chipmunk had had a small slip string taped to the windshield, when reduced to just airspeed on the instruments, would one would have been able to remain in control with just those two?
The battery looks really large to me. What AH rating? Looks like A lithium.I am installing two MGL Avionics Blaze instruments in a pod. I will also have an engine rpm and a rotor rpm gauge that will be powered by the Rotax 12V system. I would like to have a very small 12V battery backup (preferably in the pod) that can last 30 minutes or so If the Rotax power drops. It would also be nice to have to power the instruments with the engine off for adjustments. This battery will need to be able to remain connected to the 12V bus when the engine is running and not get over charged.
The two Blaze instruments will pull 95mA @12v minimum. I don't know how much the engine tach or rotor rpm gauges will pull.
Good point about prop blast, hadn't considered that.I think you would need a mag compass as well for it to work, anyway.
I certainly understand avoiding the head motion.Good point about prop blast, hadn't considered that.
We did have a large P type down between the legs, but by the time we had blanked most instruments were in actual cloud, the last thing we wanted to do was to be glancing down at a 'whiskey' compass which reacted slowly,...and was subject to compass errors.
When I was in Saudi we had a Saudia 737 take off from Madina just before they closed for the night. They then had a total electrical failure and requested a return. The tower advised them to instead remain heading West VFR till they hit the coast, a very short distance, then turn South fly the short distance down towards Jeddah then see the city lights and land there.For accidental IMC, I have heard it suggested that the compass sensitivity on a south heading, and known reverse error response to heading change, could help one hold a course while descending out of cloud. Never tried it for real.
