I don't know about the FF specifically, but most 5 and 6 inch tail
booms are .058" wall thickness, I think.

The Fireflys use 6061-T6 Aluminum. The tube used to be 0.049" which is a
non standard size. They are now 0.052" wall thickness, which is a
standard size made by Alcoa.

Hi Guys,
Have been a member of this list for a couple of years. Really am
thankful for all the info available and I guess it is time to ask for
some feedback on this subject.
I am flying a Twinstar MKII with a Rotax 532. I have put 340 hrs of
great flying on this engine with no problems. I am now looking at a 300
TBO as that is what is recommended. I fly on the West Coast of Vancouver
British Columbia, Canada. Most of my flying is in the mountains or over
water. I will fly 27 miles across the strait of Georgia to Vancouver
Island. or over 6000ft passes to get somewhere.
Always in the back of my mind is when is this little 2 stroke going to
quite. Most of my fellow pilots here have gone over to the 4 stroke
Rotax and can't say enough about it. I can't go up
as I am already over the recomended power for this aircraft. I yearn for
the peace of mind that a 4 stroke delivers so I have been looking for
something better for a couple of years now.
The HKS700E seems to be the answer, my only reservation regarding this
engine is the air cooled system. Any feedback would be appreciated
Regards
Harry

John,
Thank you for the info. It looks like a FireStar could be easily be moved
into the ultra light vehicle 103.7 category by getting rid of 21 pounds.
This could be done by smaller wheels, less paint and a lighter engine.
Using AC 103-7 Appendix 1, 2, 3 & 4, a 33 hp Mini III Simonini engine would
push it 63 mph. Changing to this engine would put the FireStar under the
weight limit.
Calculations for a gross weight of 550 pounds gives a stall speed of 27.5
mph. If one assumes a converted (re-engined) FireStar weighs 248 pounds
dry, with five gallons of fuel and flown by a standard FAA 170 pound pilot,
the wing loading would be 3.2 pounds per square foot. This would give a
stall speed of 25 mph with out flaperons.
One major advantage to converting is the extra load carrying capacity of
fifty pounds over a FireFly.

Herb,
There is no housing for an oil thermostat on the HKS that I know of - an oil thermostat
can be plumbed externally. Tuning the airflow through the radiator to
maintain an acceptable range of temperature is simple, and seems to work well
for most people.

Mike, would you scan and post the HKS report? I couldn't get your email address
to work.
Harry, look here: http://forums.matronics.com/viewtopic.php?t=13013. So far, I haven't had any cooling issues with my HKS.

| Subject: | HKS engine install |
Herb, Harry, Dave et al, Here are the addresses of the HKS Installation and
Operation Manuals.
Installation manual
http://www.hpower-ltd.com/pdf%20files/IManual_Eng.pdf
Operation manual
http://www.hpower-ltd.com/pdf%20files/OManual_Eng.pdf
In the current version of the installation manual there is no mention of an
oil thermostat. Unlike the Oddysey install, the second inlet to the oil tank
is not plugged, but is used for a line coming directly from the engine. What
you get is one line coming from the engine going directly to the oil tank
and another going to the oil cooler and then to the tank. The oil temp
sensor is at the bottom of the tank along with the line returning oil to the
engine. When I talked to Dana at Flightstar he advised doing the same thing
Dave has done, just cover a portion of the oil cooler to bring the temps up.
Harry, I'm unsure of how to answer your question about cooling, but perhaps
this will help a little.
The Rotax 912 has air cooled cylinders and water cooled heads. The HKS has
air cooled cylinders and oil cooled heads. In truth all "air cooled" engines
get roughly 30% or their cooling from their oil, the HKS just goes one step
further and circulates the oil through passages in the heads just as Rotax
does the same with water (water and ethylene glycol mix) The principle
difference between the two engines oiling systems is that the Rotax is a wet
sump engine and the HKS is a dry sump i.e. Rotax pressure feeds oil to the
engine after which it drains into the sump where it is picked up by the oil
pump and the circulation begins again. The HKS has a second scavenging pump
that picks up the oil from the sump and sends it to the oil tank, hence
"dry" sump.
