You do seem to have tried everything obvious. a fellow over here is chasing high CHT across all cylinders and hasnt fixed it yet. Frustrating - which you already know. But he did tell me the correct ...

I dont use either method because they only read the temperature of the lu ...

Had same happen today with a gel pad. Thought I had squashed some sort of bug on my neck but the oily stuff kept flowing.

It had been a sunny day with the 701 parked up for lunch. This is the 3rd p ...

I built one specifically for my 701 and its done well for 3 years now. In that time its been moved along the airfield once without being disassembled.

If you join the Zenith.aero site there are pho ...

your placement of the OVM is not the same as Z20 or Z21 because you have changed the way S1 (S1 and S2 in your diagram) are wired. I cannot offer a different method as I don't use the OVM but i ...

I don't wish to over-analyze your schematic, however there are some features that need clarity;

The alternator contactor, rel.3 does not disconnect the AC from the regulator.

Minimum steady state cranking amps is 75 for the 912S

This is described in SB-912-042 R1

We did this test on a troublesome 912UL and got 71 amps. Although the SB does not apply to diagnosis of ...

I always felt the "bunny hops" method that permeated the ultralight scene a couple of decades ago was an accident waiting to happen - agree with John Bolding and others do not try this on a ...

Phil,
The plans (and ZAC website) state the range of engines and weights suitable for the current (1100lbs) CH701.

I think that includes a 65hp 582. I did once fly in the original (960lbs) ...

The fact that Jabiru start leaning below around 70% power does not imply they approve of running the engine LOP at any time.

The econony jetting never operates in the LOP zone, even the first versi ...

Those senders brand ELO gave out early, best use the VDO as replacements. The port they are screwed into is looking straight at the oil pump output, which peaks and pulses sharply at times, as reporte ...

In practice, I fitted the bungee across to the RHS fuse and ahead of the crossover to the top elevator cable that comes off the control horn, so this is the lower elevator cable. Reason for this is t ...

Bob,
The mags are statically timed. Unlike the Rotax, they have no low rpm retard. Only adjustment is for magnet gap.

High EGT sugggests you have lean mixture at full throttle. Make sure th ...

The charging system on the Rotax is fairly rough and can put out different noise depending on the state of the battery. You could check that the required 40,000 uF capacitor is present in the wiring i ...

Ross:

Notwithstanding my opinion that the most important thing is to ensure the weight/balance is within design limits for TC 10141E compliance, and a "701" without the slats is NOT, you ...
