Just a couple of minor issues with the EMS and the coolant temp indication, entirely due to ‘finger trouble’ leading to a “rubbish in = rubbish out” computer scenario! G-CIOF feels very new (she is) and flies just as nicely as big Sister G-MOYR. The Rotax 912 iS is noticeably more powerful at towing RPM and pulls very smoothly throughout the full RPM band. The weather and sodden airfield have held up the flying, but the coming week looks a bit better, so fingers crossed.
G-CIOF’s Permit Application is with LAA Engineering, and we have purchased her smart ‘fireproof’ owners plate – the last real building job is to rivet it in place behind P1’s seat! G-MOYR took well over 500 hours to build, and G-CIOF has used up over 400; the 912 iS installation, although simpler, has taken a lot of finessing to get exactly right. Inspector Mark was pleased with the end result, and we should soon be able to fly our new tug soon, give her a really good shake down, check out all the systems, and get her full Permit to Fly. All being well we would should be towing YGC gliders early in the New Year, and have time to give G-MOYR a rest and some TLC (wash, polish, paint touch up, hangar rash, new rope …….!!).
Watch this space, and the Club web-site for details of conversion training and briefings that will take place over the winter period. The Rotax 912 iS is a little different to its carburetted ‘cousin’ but is a great bit of kit to tow with.
Jim’s meticulous wiring and soldering is nearly complete, and connecting the panel to the engine via the wiring looms is well under way.
Airframe and engine installation is complete, and the retract winch is installed and tested.
Thanks to everyone who has helped with this fascinating project. Our first EuroFox has now launched over 4000 gliders. This is our second build, and the new aircraft has the Rotax 912 iS injected engine. The installation appeared to be very complex owing to its extensive wiring looms and connectors, but as the many connections are made and checked it is coming together really well, and will be very neat and tidy. The engine now has coolant and oil, and no leaks! Once the wiring is complete we will purge the oil system and fuel up so that the injection system can be leak checked and flow rates measured.
We are also very grateful to John Barrott for his help clarifying the 912 iS wiring diagrams, and EuroFox UK who are using our project to finesse the 912 iS kit.
Off to Nitra in a couple of weeks to cover YGC’s second EuroFox. Did some towing with the 912 iS demonstrator in far from ideal conditions at Sutton Bank – G-TTUG is a ‘nose dragger’ with skinny tyres, but her performance and engine handling are slightly better than G-MOYR’s. The injected engine installation is a lot neater, and will save at least some build time. Working towards delivery to Sutton Bank at the end of May/early June.
