With airbox temps like those there would have to be a significant power loss. A temp indication for Carb body wouldn't go astray..Nev

Yep I agree

Mine in my savannah used to do the same on a hot day. If CHT/water temps are ok (as well as oil temps) it should be fine. Detonation is the main concern but it is to a lesser extent on water cooled heads. Use as high an octane as you can (98) to help against detonation and monitor engine temps.

Thanks for the info. Yes Water temp around 90 oil temp low may need to blank off oil cooler if not reach 90 in flight. Hoping just heat sink from no forward motion, also my need to check gauge.

The Loctite superglue GEL is better because it fills the spaces under the base and they don't peel off so easily. The nozzle is not hard to use with the Gel.

Thanks used that all good VGs on wing now just waiting for paper work to go thru RAA

Doing engine runs before its first flight i have noticed that the airbox temp gauge creeps up to 39 deg at over 4500 rpm is this normal when the plane is not moving forward or is there another problem. Water temp 85 deg and oil temp 90 deg. My top cowl has an open slot in it, tried blanking off made it worse.

Suggest you post a picture of the hole pattern in your wing, Jon Brown.

 

The ICP vortex generators have 2 locating lugs each, the holes are in a pattern of 4, which gives the paired VG pattern, as on the blue wing pictured above.

If you have patterns of 3 holes, as you previously stated, it sounds like they were intended for a different VG: you may have to get suggestions/advice here on how to proceed.

 

FWIW I have also used Stolspeed VGs, they are robust and do not require locating holes. They are supplied with a simple pattern/jig that sets the spacing and angle.

Hi Guys Dur when i actually went and had a look at the wing instead of relying on my memory. Yes it has 4 holes in the pattern so yes very obvious how they fit. PS thanks for all the great info and Photo.

As suggested earlier, you really are best to contact JG at Stolspeed, who is the authority on all this.

Thanks will do, I looked at there web page and lots of good info, they use there own VGs that are different from what I.C.P. supply and they look more robust.

Next Question, My leading edge has sets of 3 triangle set holes all along the top. Presume these are for the VGs. Savannah send me a set of VGs that have 2 lugs hope same hole spacing as holes in my wing, need to check tomorrow. Does any one have the page in there build manuel that shows the orientation of the VGs. please email to me or send photo even of the VGs on the wing my help. Thanks [email protected]

Hi can some one tell me what the MAC is on a 2005 vg with the new leading edge not to slats thanks trying to figure out C of G

Afaik all aero engines are independent of the battery so it keeps running if the battery dies. If you have steam instruments the ALT, ASI, VSI & some thermocoupled engine instruments will still work so the only problem is communication which is why there are procedures for radio out at controlled aerodromes.

Now next question, were can I find any service bulletins and Ad's for the plane. I would like to make sure it is up to date.

PS I am an ex qantas AME but a long time ago, other owner is retired LAME qantas.

Thanks Peter for the Info. Does your Savannah have the jury struts.

Well then you have 2 of small 3mm alu plates about 50mm x 40mm going in between the leaves in the main strut attachments at the wing and that increases the MTOW to 600kg from 560 kg ???...I thought it was not enough for a 40kg increase but supposedly designed by the Germans for that increase

Thanks Kyle, I'm even more confused now. I think I will just leave it as it is for the time been.

Hi have just purchased a 2005 VG completed but never flown, have just noticed that it does not have the jury struts on the front wing support, was this a mod or have they just left it off. Is it worth while doing the 544kg to 560kg MTOW mod. PS I am new to any forum so don't know how they work sorry if I have done this wrong. Jon
