RE: 3d flyers in Colorado
Arvada has the nicest runway-- by FAR. It's concrete. It's 750' long and 50' wide. Very nice pitts and frequency control. Excellent TX impound facilities. They got PLENTY of nice wooden "picnic table" style benches and a large (50'X50') canopy for shade. Nice starting tables right near the flightline to keep running engines away from the pitts. No running water and a Port-a-Let for bathroom facilities. No Electricity. Bring your lunch and your own lawnchair. Overall- very safe and a nice runway with good pitts.
Arvada also has a 600' +/- grass runway. VERY FRIENDLY guys. AMA required.
Cherry creek has an approx--400' asphalt runway No tables or setup area and they start and run engines in the pits-- pointed right at ya!! VERY FRIENDLY guys. AMA Required Overall- nice guys and a decent runway.
Chatfield has an approx 600'asphalt runway with a crossing runway 90degrees to the end that's also about 600' long. No tables or benches. Decent covered canopy about 30'X60'. Terrible pitts and frequency control. AMA----""kinda sorta, I guess --if you think ya need it--but we don't care"" Overall--pretty nice runways, but terrible pitts and not real safe.
On the DA 50--they take GALLONS of fuel to break in. And it will get a lot better with time. Most take at least 5 gallons to get nice. 10 gallons is just finally getitng broken in. I'd guess that you should be able to use a 22-10 on it--but I can't say what kind of RPM you'll get with that prop.
My G-62 is on the 5th gallon now. It's just getting smoother and smoother. I may jump to a 23-10 prop eventually. I'm still running 40:1 break-in oil in mine. I might switch to a synthetic Amsoil 50:1 after 5 more gallons.
