ok sounds like a plan! if possible bring also fresh air from the oilcooler to the cold side. helped on my voodoo a lot!

Please show how you directed the air flow from the oil cooler.

Hi Thomas,

where did you source the black ducting that you used?

The Black flexible tube is from a car-part shop. Aluminum with paper covered. The inlet is made of wood.

Thanks Noah.

I have to break away from this one for a bit and do some maintenance to my own fleet, maybe do some flying too.

Back soon
Peter.

Progress, indeed.

Looks great, Peter

And how are you finding the assembly/fit? I suppose on some level a bit tedious and finicky, yeah?

Hey Noah,

The fits are challenging but not impossible, "tedious and finicky" to say the least.

Appreciate the updates, Peter. Still keen on this kit, although now probably unavailable anywhere...

Gear mounts look minimal in their capacity to support the size/weight of this model. Maybe it's just deceiving based on what I can see in the pictures.

Keep up the outstanding work!

Noah

Thanks Noah,

The pictures are deceiving but it won't hurt to lay in some C/F around the gear formers, the drywall screws holding the retract are only temporary.

magnificent work, peter!

did you have to plant 5 lbs of lead in the (empty) tail just to keep it from nosing over on the bench with that massive engine installed?!

kidding of course... but I will be anxious to see how ballast is managed (and what's required in the "end").

best,

noah

She stands up on the gear with no ballast in the tail.
Latest pics.

Finished hinging the wings - a good time for a change and finish the L39.

Nice work. The hinged surfaces look so much better than the new CARF Mustang. The hinges come finished and the gap between the stab and elevator or rudder and vertical fin are terrible. I’m just closing my eyes to it...

Are you making the canopy slide? I’d like to see how you do it if you do.

Yes, the canopy will be functional, the kit came with an air cylinder and slides.
I may substitute the air for a Firgelli / Actuonix actuator.

Superb work as always Peter! I particularly like the CF duct from the radiator inlet that you made. Did you split the duct to get it off the plug and then join the halves?

Yes, to remove the outer skin I make a small slit down the side and pry off while still slightly soft.
There is enough memory in the semi-cured resin by this time it resumes its former shape.

Great thanks for the info Peter. I presume you are going to feed that intake into the cold side of the engine. How are you going to exhaust the hot air from the engine bay? Apologies if you have already explained this in the thread.
