Hi JB, Our Savannah VG 2010 build has been running with no oil cooler (Jab 2200) since build, no problems with overheating, however, last Thursday, 19 04 2018, 27 degrees and the hottest day for a long time, after a 1 1/2 hour flight the oil temp was up and pressure dropped to 2 bars, normal pressure for our one is around the 3 and a bit bars, at 2400 rpm, I have the oil cooler kit and am thinking of fitting it next service, I looked at your pcs on media, did you sort it ? Thanks Dave.

The pads are still good but I will sand the surfaces to remove the glaze from the rusty discs and see where I go from there with a fluid change, apart from full power check they don't really get a lot of use which is most likely a big part of the problem, we find the Savannah generally stops quick enough with full flaps being they are the whole length of the wing we generally land on first stage then put it on full on touch down that seems to work well for us

Thanks for the info, my savannah does not have a kennel and so lives out in the elements, my discs were very rusty as were the slider rods on the callipers, I am in the process of rectifying these problems hence skimming the discs, parts seem a lot cheaper in your area, for instance I just paid £105 for a new front leg bungee, from our one and only Savannah agent in the UK . Mine is the Jab 2200 power version and a lovely little plane to fly so I will persevere.

I think its because it directs the air flow diagonally across the top surface, since they only appear to work at stall speed it does not seem to do a lot in flight, I took mine off to change the broken ones and flew in between and to be honest I never noticed any significant difference, but since I always touch down at 55/60 MPH that could be the reason

Thanks Nev, I found it eventually in the manual, however it said "Hidrolic Minarar" I reckon that means Hydraulic Mineral !

I have just finished skimming my brake discs on a Savannah VG 2010, I found that the brakes were useless when doing full power check anything over 2000 RPM and off it went, I did not build this aircraft but I do have all the build manuals ect. I find the differential toe brakes less than satisfactory and also discovered it has hydraulic oil in the system not DOT 4 brake fluid. I am wondering if this oil is a bit thick for the fountain pen sized master cylinders and that could be the reason they don't hold ? Has anybody else had this problem ? I trained in a Jabiru with a single lever and a escort clutch master cylinder

I cured my fuel spillage on full tanks by simply making the vent pipes longer to allow a higher arch above the wings, locked them off with plastic ties no more watching the miles drip away under the wings.

I made a mould and made my own using a hot glue gun,my VG has 380 hours but I believe its UV that makes them brittle then when its windy the covers break them off

Thanks for the info you guys, I currently own a VG which has suffered a hard landing before my time and the front leg has been giving me problems with the lower rubber stop hitting the lower leg ring and putting a dent in the bulkhead ! which in turn puts a kink in the shroud around the bungee, I also got fed up with the steering rod clanking on the lower rest when taxiing, My Savannah VG is the jabiru powered version and I fly out of Hornchurch UK , ( G-TTAT) Thanks again guys, very helpful.
