| Subject: | question HKS & 701 |
Hi,
I'm new to this list. I fly a kolb firestar 2 with a HKS engine, a
great little airplane but I keep
thinking about building a 701. Has anyone used the 60 hp HKS in a 701?
If anyone has done this I would like to contact them, or receive any
info they would be willing
to share.
THANKS

DO NOT ARCHIVE
The original 701 had a 60-HP Rotax two-stroke engine. One flew with 40-HP (don't
recall how far).
Folks demanded more speed, shorter takeoffs, etc.
Now we have three versions of the 912.......80, 100 & 115-HP hanging on recent
701 completions.
The new Zenith CH-750 can handle the O-200 engine, takes off in 12 feet/4 meters,
cruises at 190 knots, lands in 20 feet, uses less than 1 liter of fuel per
day, can be built in less than 10 hours by 200 people.
Next we'll have the Zenith version of the GeeBee Racer with a PT-6 engine, bomb
racks, in-flight refueling probe, tail hook, crew-rest quarters, galley, stand-up
lav, movies and free bailout money to finance the whole project.
If the original video is still on the Zenith website, you can see Chris Heintz
flying the 60 HP version. This is the "old style" main gear, and if there are
still some early photos on same site you will see the "inverted" 2-stroke Rotax.

One thing to keep in mind about smaller engines in the 701 is that the original
plane had only a 950 Lb gross weight and was much lighter. I suspect that the
current SP model (1100LB GWT) would not perform well with only 60 HP.

That prototype 701 with the 50-HP 503 Rotax weighed 430 lb (195 kg) empty.
At that weight the HKS would also have a chance of reasonable performance.
At the more typical minimum of 600 lb (272 kg) real weight these days, it'd
be disappointing......

One 701 has been fitted with the HKS in NZ but the builder told me it was a "waste
of time" and it was not flown with this engine. A Corvair was fitted and then
changed out for a Jabiru 2200 as the Corvair performed brilliantly but couldnt
carry any payload or fuel. This was on a 960 lbs model, I understand.
The protototype CH701 (1986) had a gross wt 880 lbs and flew on a Rotax 503 of
52 hp. Used to be advised as suitable for engines 45 hp to 85 hp and weight 90
to 130 lb.
