750 Rotax 912

Started on the firewall with the installation of the mount and the oil reservoir .

Taa Daa !! We have installation of a Rotax 912ULS on the nose of a STOL 750, I have more pictures of the early part of this install and will include them in my photo album when I have a little time at the hanger.

Installation of the engine is quite simple so far, the muffler was a bear to get in, but they all are… Continue

ARF pictures

I just posted several pictures from a couple of ARF flights. ARF is Animal Rescue Flights, a group that helps get animals from shelters where they'll likely be killed to new shelters or new owners that will take care of them. If you're looking for something to do with your airplane, give them a look.

Attaching the wings

Over the past two weeks I have been getting the wings on the fuselage. That is finally finished, flaps on and wired except for the trim. For any one interested, I suggest that the flaps and ailerons not be drilled until the wings is trimmed and bolted on. It was very hard to get the flaps on past the already riveted ailerons and getting every thing adjusted. The other issue is the flap torque tube. I drilled my bolts on the tube as per the manual and it would be much better to drill the left… Continue

02-21-2009 Today's Adventure


With just over 400 hours on my plane, today it was time for yet another oil change. While I was at it I installed an oil drain valve on my Jabiru 3300 engine. In the future this will allow me to change the oil without removing the bottom cowling.

After the oil change I went for a 130 mile flight. There was an overcast at 3,000 today so this was a low and slow flight over the coastal mountains and out over the… Continue

The hangar Gods.........

After two years and starting off at number 92, the planets have aligned and I just signed the lease on my T-Hangar that I take possesion of on March 1st. This is really good on alot of fronts. I am just getting ready to paint (not in the Hangar), and will begin final assembly which is pretty much impossible in my garage. My wife is finally losing patience with decor de aviation. We have wings in the living room, slat and flaps in the office,instrument panel in the dining room, and her car hasnt… Continue

750 Nose Gear

Not much visable progress in the last few days, All steel parts have primed and painted, then a trip to Zenair for the Rotax FWF package.

The Rotax cowling is one of the prettiest cowlings I have seen. It should look just fantastic on this 750.

I was able to spend a little bit of time and get the main landing gear in place, the rubbers for the… Continue

Aye Captain we got wheels

Today was a late start and I must finish early to catch up on the 290 messages since Sunday, so it is simple tasks for the day, best place to start is the landing gear. Here on the table I have inverted the gear leg and used my axle drilling jig to ensure straight holes.

Perfect holes make this a simple as fast installation, though I went through 3 batteries in the cordless drills to do these 8… Continue

Heating the Cabin

Too bad this site came around when it did...I keep a blog of building activities at As you can see I have been continuing to slowly work on the airplane. There are days when I want to give it to the scrap dealers and other days when it is great to tackle another problem.

The engine is pretty much complete, so now I must return to the problem of a heater box. I think I have the box figured out, but not the distribution in the cabin. Particularly to the back seats.… Continue

Photo window - Flying open ?

Greetings from Scandinavia - I fly a Czhech built bird with curved side windows. I'd like to do some photography and have marked for a little photo window, I have to cut out. Only, I'm not quite sure how the double curved polycarbonate window will react tothis.

Also considered flying ophen. How easy is it to get the door on and off these looong piano hinges - And how is flying open when compared to flying with closed doors?

Hope for reactions on… Continue

Monday Maddness on 750

I suspect large visual progress is now over, time to get the hidden stuff installed like the controls. Some Wiring and fuel lines.

Unexpected was the installation of the windows I would rather have left them off but they are captured under peices that need to be riveted in. They look real nice but I will… Continue

02-14-2009 Today's Adventure

Today I flew 310 miles under cloudy skies, and occasionally in Marginal VFR conditions. It rained lightly off an on with winds gusting up to 18 knots. I was able to dodge the bad stuff. It was a lovely experience with lots of low altitude flying. For the most part I had the skies to myself.

Before I fly in wet conditions I clean the canopy and treat it with Plexus. It helps the water bead up and stream off which improves… Continue

750 Rivet-O-Rama

Well it is Sat Feb 14th and what better way to say I love you dear then to hand her a Vixen file. Yep it is time to de-burr the forward fuselage and my sweetie wanted to spend the day with me. Isn't that romantic, I married my best friend and even after 22 years she is still happy to help in the shop.

We start by removing the forward fuselage again and completely disassembling the whole thing. be-burr every part and chromate mating… Continue

No- Dissasemble Stephanie ( Short Circuit Movie)

Well that was it I ran out of cleco’s, so it is time to return to the rear fuselage and spend the day in disassembly and de-burring and Zinc Chromate. But I always look forward to the riveting, Stepahnie was not around to stop the dissasembly so off I go...( if you don't get it don't worry it was a 1986 movie filmed in Toronto)

I always look forward to riveting but seldom seem to do very much of it. Today was… Continue

Taildragger 801

I am just wondering if anyone has though of building a tailwheel version of the 801

Cleco's sacrifice there young!

"Actually, there is a reason for the apparent death of clecos------- Just as it has been noted that coat hangers left undisturbed in a dark closet will mate and multiply, and their progeny will mate and multiply, etc., clecos are known to be intensely hostile to each other, no matter what their size (breed). What happens is that, when left undisturbed in a dark shop overnight, they attack each other, killing each other off at sometimes hideous rates. Also, being intelligent creatures, they hide… Continue

Perfect day to calibrate airspeed

Today was a perfect day to perform flight tests for airspeed calibration of the STOL CH 750 (for ASTM F-2245-05 compliance):

With Roger flying the STOL CH 750, I tracked his speeds with a handheld radar (just like the police use in speed traps). The unit is actually a "stationary Dopplar radar" with a "conical microwave antenna."

With no… Continue

Lemonade for Sale

Lemonade Anyone!

Today was a bit of a surprise that Jarod has a P.D. Day and Mom is unable to be present? So off to work with Dad, Jarod has one simple rule to contend with, either Keep Jarod Busy or Jarod will keep you busy!! Jarod started the day making a few stabilizer ribs for his own plane but quickly petered out and opted for building a Lemonade stand. He has not learned the fine qualities of Coffee and I will not introduce him to them, he… Continue

The Morning is a loss!!

Today is Wed and as such I have an open hanger morning for the local RAA chapter which entails that I host the morning coffee and doughnuts. With word getting out that I have a new kit in the shop, I have more visitors then usual. SO I do not get to work until noon again today. As you will notice, the table has gone bye bye, I use a table when I am working on flat stock but as soon as assembly starts I use two saw horses adn two 12 ft 2X2metal peices with several 4ft metal peices. This works… Continue

750 Fuselage, making a place to sit

It's official, as you can clearly see, Jon is agog at how everything is cleocing together. The assembly of the seat area necessatated the joining on the forward cabin floor and gear channel to the rear fuselage to firm up a couple of areas where angles are fabricated beneath the seats. While it was together we drilled the holes in the side extrusion to the rear fuselage side. Once the forward side skin and the gear channel was clecoed to the rear… Continue
