Dear Barry The increased fuel flow with altitude is due to the carbs going rich. Despite the mis-information to the contrary, the Bing constant vacuum carbin the 912 does not compensate for altitude.
Dear Graham and Barry Sorry to harp on - the effect is proportional to the squatre root of density altitude for any king of carb without an aneroid. On a cruide (Continental style injection system) i
Dear Miles I have a better way of doing it. Pure machanical with electronic trimming. There is no use in messing about with car based solutions. The only one which will succeed in the long run is one
Hi Duncan No, I have my diesel hat OFF now, believe me. The point I would like to make is that while electronic injection is technically feasible, the cost of providing the required redundancy and co
Dear wiggly-amps technofiles Re EFI for GA: I would assert that the failure rate of the whole system ie black box, looms, power source etc is significantly worse than duel mag systems. The duel mag a
Altitude compensated electronic fuel injection for aircrfat is a great idea provided we can find a way of leaving out the electronics (t least from the safety critical loop) ! What we need is a good
Dear Duncan These figures are most helpful - brings the whole scene into perspective. I think that the 1:500000 sounds about right for a whole system integrated by one manufacturer eg. a Ford engine
Dear Thomas You can see some details one particular solution to altidude compensation with lean burn at: http://www.wilksch.com (if you are not already aware). Let me have any questions and I will ei
This is wonderful news. Graham has been a terrific help with our engine project and the Europa installation. Ever since I discovered Graham I have been asking why "why can't we find some more Graham
My son Sam designed and makes some "lift rods". Winds the ramp up on turnbuckles which is much more civilised that the standard heave-ho knees in the mud etc. If anyone is interested please email Sam
There is an informal agreement but no final decission on who will do the engine installation kit. I will be talking to Europa/Liberty abou this again soon. Most of our orders are for Europas, so we
Dear Ed We have only done the one short flight in Europa G-WWWG Other flying was on a Cub in 1997/98. We still want to clock up more test cell hours before more flying on G-WWWG. Regards.......MARK W
Dear Ed and Rob and Forum Sorry I forgot about the weight! There is a penalty but its not a hugh amount over a rotax 914 which gives similar power/altitude performance. We are looking at Europas with
Dear Rob, Paul etc These are from the Rotax brochure and/or Andy Draper (all in lbs): Rotax per brochure -123.0 Oil cooler hozes and fittings -3.6 Coolant Radiator hoses and fittings -4.4 Cooling duc
Thanks Eric. That brings the delta back to 70 lbs which is what we have been telling customers for some time. However I think I have forgotten that our engine needs a bigger battery to start it so we
Not correct! Starter size depends largely on the size and compression ratio of one cylinder- not how many of them. There are some wonderfully light and powerful starters on the market now. Valeo are
Dear Bob I have managed to source some Aluminium cables for G-WWWG. Let me know if you want some. Should be less that 100 for a pair. ...............MARK WILKSCH
