Stephen,
Dave Donald is at Boonah and they converted one
in the last few years. You don't need the
tailwheel conversion and both Boonah and
Kingaroy's C150s are still nosewheel types.
Performance of the 180HP C150 is impressive. I've
watched a launch behind a 235 Pawnee and the
Kingaroy C150 with ballasted 15m gliders with the
second rolling as soon as the first lifted off.
It isn't at all certain that the 235 Pawnee is
any better under those circumstances than the C150.
The O-360 Lycoming used is essentially 2/3 of the
O-540 in the Pawnee. Only 4 cylinders to fuel and
overhaul instead of 6 for around the same towing perfomance.

I was a bit interested this morning too, so I
did a quick hunt around on the internet. I think
Daves guess is a bit on the low side.
Airframe : going by costs of 150/152 from the
latest aviation trader (about 12 aircraft) costs
range from 30k to 65k but typically fell in the
45-55 range for aircraft with about 6000 hrs on
the airframe. (the $30k one was a real outlier
and would be a bit of a clunker I reckon, the
65k one "only" had 2000 hrs on the airframe, least used by a long way).
So Airframe : average 48K, best 65k
Had a look at Lycomings 2010 price list for
O-360s (there are 140+ types ! not counting IO, AEIO etc)
With exchange, a new O-360 $41k, rebuilt zero
hours $29k. BUT up front they say they are
reluctant to exchange different types, so add
20% to either of these prices for a straight out
purchase (though you should still be able to
sell the old engine locally and recoup something).
Then looked for conversion prices. Found a site
called Aeroprices which quoted a tailwheel kit
as US$2225 and an engine upsize kit as
US$5835-7622. HOWEVER (and this is the
interesting bit) the STC for both these kits was
owned by "Aircraft Conversion Technologies" who
seem to have folded as a business in 1999. The
STC ownership seems to have then passed to "Del
Air" who have little in the way of info on the
web (only reference by third parties). They
could be gone too. Who owns the STC? The upshot
being the prices given must be pre 1999 prices
so a conservative 50% inflation since then (I would bet closer to 100%) gives:
Tailwheel kit $3300 (which seems neither here
nor there in the overall cost of the work)
Engine fit kit $9800
-------------------------
Finally if we were to buy a 150/152 on the
Australian market and upgrade it as above (not
counting labour!) an "average/cheap" conversion
would be about $90k and a "top of the line" job would run to about $120k.
I haven't allowed any cost for labour (and
chasing around after who owns the STC etc). I
expect you would get some change (but not much) out of $10k
After this expenditure you would still have a 30+ year old airframe.

Why would you want a taildragger 150/152 (even
though they exist)? If you get a tricycle
150/152 that nearly every GA pilot trained on,
they are a ready source of tug pilots (when
endorsed). And you don't have all of the issues
of ground handling that goes with a taildragger.
Airframe 20k
Engine 35k
Conversion 15K
= 70k
Pretty rough figures across a couple of years -
the engine may be more or less depending on
condition. Also, most modded 150/152 have a
recurring problem shaking the rivets out of the
tailplane skins/spar, but with proper maintenance this risk is mitigated.

Can anyone supply information on current cost
purchase and conversion of C 152 to taildragger
and 180 hp engine transplant and a LAME who has done it before?

One has to ask the question - why?
If cost is the answer then a 180HP Cessna 150/152 is the best alternative.

Does anybody out there have any information
regarding the launching of gliders by Motor
Falke, or indeed, any other motor glider that
may be used to launch? Iâm not aware of it
in Australia ia but I understand that there may
be some such happening in Europe? I am aware of
Ultra lights acting as tugs but Iâm
speciecifically interested in motor gliders.
