For Mintor eyes only

[David Harmon]

Eric...there should be a considerable weight savings as well considering
less fuel needs to be carried as well as less weight per oz due to half
the nitro and less oil too than the DZ.
I need to make some decision on a new engine and am primarily concerned
with everything you said but I'll add one more....warrantee and
authorized service. Someone asked the warrantee question a couple of
weeks ago but I never saw an answer.
I just don't want to go back to 83' when the only parts for Rossi were
in someone's garage.

I've been flying a borrowed DZ and man, that puppy does slurp it up!!
They don't call it a 'Dingo' for nothing!! 

Best

 In case you have had enough of this topic just hit CRTL-D

If you have not had enough, here is today's lunch results.

It was warm and muggy today after all of the rain. The Mintor had the
"target" 17 x 13 APC strapped on the front. With three gallons through
the engine it was time to really see what the 1.70 was made of! Engine
was set at 7,900 rpm on the ground using Powermaster 15/16. The Hydeout
was ready for the ride. 

Here's how it flew P-03, or at least a description of a few of the
maneuvers as I saw them unfold.

Sq. loop on corner - Straight and level into the 45 climb at 1/3
throttle. Nice even pull. Increase power around the first corner to 3/4.
Perform 1/2 roll and got on to full power (WOT). Plane continues on at
slightly increased and smooth speed with the real need to back of the
gas over the top corner. Long down line 45's and the engine responds
smoothly on the bottom pullout to level. No gurgle. Upon reflection it
was a big loop before I noticed.

Hour glass - very similar with a lot of grunt on the up 45 line.

All vertical lines were easy with a big punch over the top of maneuvers
such as Humpty-bumps. The down lines were flown very long to look at
speed etc. The idle can be set low and it does not quit. This helped the
down lines and allowed pull-outs that did not bend the wing tubes. The
idle for spin entry was actually too low and a purr had to be added to
both reach the middle and get the nose up.

The big test was the figure-9 with 3 x 1/2 rolls going up. An entry at
1/4 throttle as I pushed followed by a incrementing amount of throttle
as each 1/2 roll was executed ending in full throttle over the top of
the 9. This was a big 9. Too big for good points but just right for free
adrenaline shots!

So how does it (1.70) compare with the OS 1.60. About 200 rpm less on
the ground but 4.0 oz lighter. Vertical behavior very similar between
equal weighted planes.

So how about the DZ. In the same plane it was clear that the DZ had the
edge in the mid range grunt-dept. Vertical snap rolls were equal however
in vertical line recovery.

In the end it comes down to probably five things. Price, Serviceability,
Reliability, weight and price. Depending upon what you need you can
chose the performance of a 2-c or a 4-c the personal taste of sound and
throttle timing.

I would run all three for equal fun, but as far as price goes, (The OS
in this case is an FI), the Mintor has a big edge.

Regards,

Eric.
