About a 100 hours per year in the last 5 years (with a low of 70 last year) - fairly sure it was 1QT every 5 hours when I bought it in 2019 so not a huge change.
tomahawk and skipper feel big inside and certainly wider feeling that aa1 (for reference; I'm 6'2 and fat...). the aa1 was more fun/sporty and felt like you're 'wearing' it but had no wiggle room on longish flights. Tomahawk was great and I would have bought one but needed a trifle more...
I fill it just to 6 qts, as anything above that just blows out immediately. spark plugs not fouled. based on your comments, perhaps I should consider an old fashioned 'top overhaul' although I know these days, the benefits of that are disputed by gurus such as Mike Busch..
same engine in my pa28 - oil turns dark after 2 flights, consumes 1QT every 4 hours and has been doing this for last several years (all compression mid 70s) - I thought it's high, mechanic says 'normal'. I just fly and remember to add oil after each long x-country..
I'm old fat and a heavy smoker; pulse O2 down to 90% by 10,000 and 88% at 12,000 - with G5, 96% at 12,000 and 95% at 14,000 (with just me plugged in), with second person (not fat, non smoker, healthy and younger...), just 2% lower at 12,000.
I have a Trio autopilot which does EXACTLY what you want; you can turn on either servo air both. Never thought that would be a useful feature, but it is!
I'm on year 4 of hangar less parking in the warmth of Las Vegas - tank 'lives' on backseat, no problems. (I do have sunshields in all the windows, but the inside temp is still oven like 6 months of the year).
I've done the trip (well, almost - Chicago to Las Vegas NV) - a few times. I always plan 2 options; same as you via ELP and can do it at 8500 or via ABQ at 10500 with the added bonus of stopping of at Alamogordo or other interesting places on the way. I make a final decision on the day; if upper...
PA28 - O360, my number 3 hovers just a hair over 400 on climb out of high DA - but only 380 when I occasionally make it across to 'normal' temp/elevations.Back down to 380 ish in cruise at 10,000 DA
When coming out of LA basin VFR, I go Rosebowl, follow 210 freeway to the I15 interchange, then up I-15 to KAPV for fuel at 7500. Using FF, they will hand you over to Joshua approach for descent to APV.
KAPV runway absolutely fine (I pop in there often for bathroom break, cheapest fuel in the area and a lovely little airport cafe for breakfast). If you're too lazy to taxi to the cheap fuel area, you can phone the fuel company and they'll fuel it for you whilst you enjoy breakfast...
Kidwell's runway is actually well looked after (well, it was when I last landed approx 2 years ago..). I flew in with a PA28 with wheel pants and had no problem; it's mostly hard packed sand with some gravel and was pleasantly flat. Remember to do a rolling take-off though to avoid prop damage.
my 180 does 120kt at 65% happily. Also, yes, you COULD pull the power back in a 235, but would you?.. Personally, my final decision was based on the costs of long term maintenance on the big engine (inc overhaul), vs the relatively cheap O360. The one point against me (honesty at work..) is that...
I was in the same quandary a few years ago. Decided on the 180 for lower (much!) overhaul costs and regular 'feeding'. I'm based in hot Las Vegas, but - If like me - 95%+ of your flights are either solo or plus one, no problem at all at high DA. If you really need a third person with you, go the...
I have the 355 ( a 175 + com ) - easy to use, airways (!), flight plan transfer to/from handheld, no regrets - as per Jesse, mine paired with used KI209, easy hookup to autopilot (Trio). I have a separate old kx155 for ILS so lack of nav wasn't an issue (plus the delta to a Garmin 650 was insane).
