Doing our best to keep it light it has minimal interior, EFIS, Comm, and Xpnder, along with the 159 lb UL260i engine. Empty weight came in at 701.5 lbs, on digital scales, weighed twice. The firewall forward kit is currently available for any of the ULPower engines, 97, 107, 118 and 130hp.…
Well, not really. Jon Croke and I spent the last few days finishing up the Assembly and rigging for the CH750 DVD series. Now I have to get the engine and panel ready to fly. We will be changing over to the UL260i shortly and are verifying our engine mount data based on weighing it with the Corvair. More updates… Continue
For those interested in the UL260i, look for our CH650 at Sun'n Fun. I can discuss the installations for the 601/650 as well as the 750. See you there.

Our ULPower FWF kit is coming together. The cowl will be back any day now. As you can see, the engine hangs out there quite a ways. Much time was spent on determining where the engine should be located to make the CH650 remain in CG with about any possible loading scenario. The engine comes in at 170 lbs. with prop, baffles, and oil. A very light 95hp, and now there is a high compression 260 that burns 100LL and is 105 hp. The empty weight of the 650… Continue
As our deadlines approach, many things are coming together. Installing the fuel tanks is all that remains of component building. The panels is finished and is on its way to being mounted permanently. We have an MGL avionics Enigma EFIS/GPS/engine monitor and their new V-10 comm radio. The V-10 weighs almost nothing and interfaces easily with the Enigma. The Garmin transponder and a Van's (sorry) map box complete the… Continue
Today William Wynne brought by our Corvair engine and we had it bolted up in short order. I am calling the Corvair 750 combination a "Savage 750." The Savage has nearly all the necessary components to complete the installation of the engine. Only a few bits differ from the standard 601/650 Zenvair installation. The Weseman 5th bearing doesn't change the location of the prop flange and we are using a cowl… Continue
Our 750 is now up on it's wheels. It is coming together quickly now. The engine will be back from William Wynne's tomorrow with a Weseman 5th bearing on it and a mount for the 750. Jon is nearly completed with the stabilizer and one wing is about half way there. It will be a busy next couple… Continue
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
With the rear fuselage sides, top, and bottom all riveted together we have moved on to the baggage area. First the flaperon torque tube, bellcranks, and motor assembly were fitted in place. Next was the rear baggage panel followed by the baggage floor and tunnel pieces. Here they are all clocoed in place for drilling to final size. The floor and tunnel pieces will be reinstalled after the forward fuselage is joined to the rear to facilitate the… Continue
Today all the sides of the rear fuselage were united along with the rear baggage closeout. All the predrilled holes lined up perfectly and fit with no waves or wrinkles. Time to drill out all the holes to final size before disassembly for deburring and priming. Jon is a clecoing madman, especially when all the holes line up.
Today, after fnishing a few details on the rear fuselage bottom, Jon began the rear fuselage for the passengers side. The design of the corner extrusion's joggle makes an easy job of fitting the skin. Windows and control openings came cut from the factory. Every time a new box is opened, much time is spent salavating over the parts.
We are also finishing up some details for the UL260i installation for the 601/650. Look for FWF kits for this soon from FwG.

Today we started on the FlywithGus.com STOL 750. Jon Croke of HomebuiltHELP is filming for the 750 DVD series. He is starting with the rear fuselage.
