40 years of fibreglassing and I have only found one epoxy that was totally incompatible, the dreaded Rutapoxy used in the PIK 20s.

The Lancair is made with a pre-preg system so is totally cured and post cured before they leave the mould. Good sanding to prep

the glass is the key. The pre preg has a very slippery mould release system. Don't use acetone on the sanded glass! The 7781

type glass is ok to use in Pre preg form but is hard to wet out by hand. Either of the 275 or LC3600 would be more than enough

as there is no shear to worry about ( even though the rivets are drilled out the "pillars" of adhesive are left). Don't paint the wet

layed up areas dark colours and you should be fine. Good luck with it.

Yes and no!

The aircraft/ helicopter manufacturers specify different numbers but in reality it is the same resin for the bonding process with

fillers added, usually cotton flock "Flox" and fumed silica "Aerosil" mixed in to a shiny toothpast type consistency. The Lancair also

has mechanical fastening of the fuse shell joins to take any shear out of the equation. I recently used some Locktite/ Hysol on a

BK117 repair and paid about $800 for 900 grams! I don't think there resins are necessarily any better than other resins, as they

are really old technology, but they are certified by the manufacturer. The properties of epoxy resin are only optimised if they are post cured.

Hi Bruce,

Are you using the resin to bond the shells together or lay up the tapes?

Hi flyvulcan,

I have three projects that could use your turbine. I'm not that fussed about saving fuel.

Are you going to be able to supply the gas generator without the gearbox as well?

Hi Bruce,

Hi Geoff,

I helped Scott design the Sapphire and a lot of the parts were off my aircraft at the time or were modified to suit Scott's vision. I have also built

several airframes with and without the help of Scott's brother, Dean, for Steven Dumesny. If you send me some photo's of the sus areas

I may be able to help you.

Hi M3cs,

Welcome to the most amazing ride of your life!

Hi Mike,

Why don't you look at a Wedgetail/ Morgan Cougar? www.morganaeroworks.com.au

Hello Paul and all.

My name is Ray Tolhurst and I'm the new maker of the Garry Morgan aircraft kits.

My first landing in a Sierra was a shocker so I can understand the landing issues!

I found the forward visibility from the nose low flying attitude to be a real treat for a low winged aircraft. The flip side was not being able to judge the flair from this attitude.

I hit really hard on the nose wheel and bounded into the air! My worst landing ever! I was sure I had broken something but an inspection afterwards showed no sign of

anything untoward!

I also had not flown for a while and perhaps should have followed on the controls while a more experienced pilot did the circuit and landing.

I am interested in hearing from experienced and newby Morgan Aeroworks builders and flyers on this forum with a view to improving your experiences with these wonderful

aircraft.

I have just repaired a Seawind amphibious aircraft that landed up side down in the water. It is impossible to smash a canopy from the inside and sitting in a seat! I suggest a battery powered angle grinder with a cutting disc. I have installed an escape hatch in two of these aircraft now.
