Max level flight at optimum altitude to achieve 75% power, standard temp and 7.00 x 6 tyres.
Some airplanes will exceed the figure by 2 or 3 mph.
The M6 will get the same speeds and the M5 slightly faster.
The oddball is M5-210TC, a factory type certified model with Lyc TO360, ten built around 1979/80, which can fly high and maintain manifold pressure, thus fly faster. In it's day TAS was 175mph.
Fuel burn in all these engines is between .45 and .48 lbs/hp/hour I think.
Prop efficiency can make a difference.

Based on the numbers Jeremy provide there appears to be a 13 to 25 mph TAS difference between a 180 and a 235.
Based on the average of the numbers others provided that difference is 13 to 35 mph indicated.
Actually, because of all the variables (tire size, props, temps, etc) involved it looks like the TAS and indicated are pretty close to being the same differences.
Wayne, when the weather gets a little better I would like to take you up on that offer. Thanks!

In a perfect world, the rpm, mp, and airspeed indicaters would be accurate however in reality we often have large descrepancies otherwise indicated airspeeds would correlate with TAS but not in linear fashion as TAS is a % of IAS which should be corrected to CAS but how many know their IAS/CAS exactly.

I'm getting 100kts (115mph) for 30-35L/hour (or a 8 gals). That's pretty slow, but keeps me in the air for 9 hours (longest single flight so far 7.1!).
I was hoping to see that I could improve my figures, but it looks as if I'm doing okay!
So, if I can fly to empty in 9 hours, that gives me a range of 900nm - I believe no other Maule type can make that range (but they'll make not too much shorter distance in a much faster time)?
Safe flights all, Sam.
