Ok, resized photo attached, see if= this works.
have to wait until I get b= ack to town for under cowl photo's

Airframe is Australian Ligh= twing SP4000 (only one in existance I think) all others are lighter weight = versions,
empty 650Kg MTOW 1100kg,=C2= =A0 tube frame, non structural glass skin, aluminium wings, glass control s= urfaces, even has some wood for floor, so bits of everything.
210 litres fuel in 4 wing tanks.
2004 Renesis, RD1-c, EC2,EM2. GT electric CS prop.
MGL iefis avionics & Comms.

Not sure= how well this photo will show but air enters under spinner into divergent = duct which turns up into wedge duct at firewall then flows forward through = heat exchangers, oil cooler is out of the 20b Cosmo, air flows over/around = engine to front of cowl and exits in low pressure area with help of cowl fl= aps, might work, might not.
Exhaust was= a bit of a dogs breakfast, couldn't exit underneath due to ducting tak= ing up all the space, cabin fresh air inlet then dictated exhaust exit woul= d be high on cowl, will suck and see how it goes and keep trimming length o= f exhaust until soot builds up on airframe.

I'm skeptical about the 20b Cosmo oil cooler, fin spacing is c= loser than on radiator so I think it must add restriction so air might take= least course of resistance through radiator. option may be to get new oil = cooler with same core as radiator. oil cooler is 1/3rd size of radiator &am= p; they sit side by side across firewall, sharing air from ducting.

I= don't think downstream blockage is the issue. oil cooler air has clear= run along right side of engine,only things in the way is the ignition coil= s & 2 stoke oil tank ( to be removed as going for premixing of oil) wou= ld be more of issue for coolant air as that has the block, intake & exh= aust manifolds to negotiate.
putting th= ermocouples on is on the list to do.

Good to hear of another proje= ct in the making. Be good if Tracy decided to sell drawings for his drive i= f he cant get anyone to take on manufacture, plenty of places here capable = of making them. just 1 off's will always be more expensive. or is Neil = thinking of going into production of his? I got a 20b for next project whic= h will need a drive also, once I find a suitable airframe.

Hi Andrew,=C2=A0

Good to hear that another rotary is '= ;close' (to flying). I noticed the 1st line 'without photo'. Di= d earlier attempts bounce? I think the message size, including attachments,= is around 200KB. Try resizing the image to 150K or smaller. If you need he= lp resizing, let us know. There's a plugin for Win XP that makes it ver= y easy; Win7/8 is a bit more convoluted but not that hard. I for one would = love to see as many pics as you have time to send.=C2=A0

Please help those of us who are memory challenged & let us know = which airframe. Runner length shouldn't be an issue (I hope it isn'= t; that's about the length of mine), since Tracy's Renesis uses int= akes about that long.
