OK, not quite, but almost! The Weedhopper is very nearly finished and if its wings were now attached, in theory, and I hope in practice also, it would fly. Today I repaired the EGT gauge connectors that were damaged when MYRO was recovered, connected and cable-tied the remaining cables and connected up the fuel system.<\/p>\n

First, here’s a shot of all of the connections in the battery and voltage regulator area showing how I’ve run the choke cable and the ‘dedoubleur’ that I made.<\/p>\n

Now all of the connections at the engine end showing how I’ve used pipe insulation as a handy sleeve to protect connectors and give a tidy appearance.<\/p>\n

\"null\"<\/a><\/p>\n

Now a shot from the other side of the engine showing how I’ve also bundled up the excess EGT and CHT sensor cabling in a similar pipe insulation sleeve. ‘Losing’ the excess cable was always a big problem on MYRO and this seems to have solved it.<\/p>\n

\"null\"<\/a><\/p>\n

My big disappointment was that I tested both the EGT and CHT sensors using a blowlamp and the only life I found was from one CHT sensor. THe EGT gauge is brand new and came with a note saying that it had been tested, so I don’t know where the problem is in that system as there was no reading from either sensor. Similarly, I don’t know for now why one of the CHT sensors isn’t giving a read-out as I’m pretty sure that both were when MYRO was flying.<\/p>\n

Now the fuel system. This is the new fuel line at the engine end. There’s a main filter where the supply tubes enter the cabin from each tank as I’ll show in a minute, but I’ve also added this secondary in-line filter to be doubly sure. It’ll also give a visual sign that fuel is reaching the engine at start-up.<\/p>\n

\"null\"<\/a><\/p>\n

Here’s the arrangement that I’ve put together in the cabin. I’ve not installed MYRO’s old fuel pump because it’s only used for priming the engine and once the engine has been started just becomes dead weight. Instead I’ve fitted a hand primer bulb similar to what I have in 56NE. For safety, I’ve included a by-pass with a one-way valve so a blocked or damaged primer bulb won’t result in an engine stoppage but which will allow the primer bulb to work normally the rest of the time.<\/p>\n

\"null\"<\/a><\/p>\n

MYRO also had two Mikuni fuel pumps as all UK AX3’s should have but I’ve done away with the lower one at cabin level as X-Airs have a similar distance to pump the fuel up from the tanks to the engine and they only have one up near the engine and the system works fine.<\/p>\n

Here’s where the main filter is located, in the well between the seats, with both tanks feeding into it.<\/p>\n

\"null\"<\/a><\/p>\n

And to end, here’s a final general shot of the rear of the engine showing the work that I did in that area today on the electrical and fuel systems.<\/p>\n

So that only now leaves the new doors to be fabricated and fitted when the aluminium tube that I’ve ordered arrives from ULM Technologie, probably on Wednesday. Tomorrow I’ll busy myself doing small things like sticking on new top door seals and things like that, in readiness for getting ready for final assembly and, fingers crossed, test flying in the near future.<\/p>\n","protected":false},"excerpt":{"rendered":"
