Ahh, the weight and balance! To be honest, I did not weigh the engine prior to installation. I pretty much took Rotec's word on the dry weight of the engine with all accessories to be 232 lbs. After the installation was complete, I put it on scales and did a rough W&B. It was obvious from the start that there would have to be some adjustments made for the Model IV. Not until after completion and paint did I do any serious work. What I wanted was the worse case scenario of a 100 pound pilot who runs out of fuel, and no baggage, to still be in the CG envelope. To do this I had to add a 5 pound lead weight into the tail. So I made a shelf large enough to accomadate two five pound lead ingots that dove tailed together and placed the shelf over the tailwheel attachment. With one installed it was on the forward end of the CG limit at worse case... with the second one installed, it really improved reduction of the stick pressure on round out. Now I can go full fuel, two 170 pound individuals, and 40 pounds of baggage... all still in CG but that takes me a little over 100 pounds over gross. No way to go out of CG forward or aft if loaded below gross weight limits. In retrospect, I would place the battery and any other weighty object of use as far back as possible, keeping in mind accessability for maintenance. Not much room in the Model IV for that, but the later models might be better. I did not want to cut fabric and install an access door on the side after all was done.

By the way, I hope to attend Osh this year. And I have to thank John King for the paint scheme and colors. He is the one that put this on his Model IV that looked so good when I first saw it. I had no idea he was going to paint his new airplane the same way. I certainly hope I did not offend John in any way by utilizing his good taste in choice of color or scheme.

Joe, Thanks for the cowling advice. Since I bought the "firewall aft" from Kitfox, the boot cowl is not part of the kit. I have started from scratch and certainly agree that it adds hours to the project. But hey, it's a fun project. I may even build a mold if the original part comes out pretty heavy. I have considered the cowling ring, but am not going for speed either; my other airplane is a Glasair that I have been flying for 12 years.
Also, if I smell that BBQ, I'll be heading that way. -- Don

Thanks Mike.
One thing about this engine is that you do get alot of lookers, especially the older generation that learned to fly behind one of the round motors. If I ever want company at the airport all I have to do is open the hangar door. Rotec does a very nice job at all the machine work. No such thing as a quick turn at the fuel pumps!

Beautiful Kitfox, Joe!
A well deserved recognition to be KOTM!
You've erased the line between form & function.

Joe--

Just drooling over your plane's photos again and rereading this thread (for the bazillionth time ).

Back to the questions:
  • Is your IV a 1200 or a 1050?
  • Would you care to share the empty weight of this beauty with us?
  • What do you have for hours on her now?
  • Any updates on performance, handling, fuel burn, etc?
  • Did you do any other mods yet?
  • Are you still satisfied with the Rotec?

I can't get enough information about this install!!


(Thanks.)

Hey Av8r!

My Kitfox is a Model IV 1200, and it is a bit on the heavy side. It came out at 825 lbs, but I have the two 13 gallon wing tanks, full sized panel, strobes, nav lights, landing lights with a pulse option, and a few other extra things to make life easier like 8.00 6 tires, thicker walled tubing on the gear for more strength and a full sized rear window. All these things add up in the long run and obviously cut into the useful load. However, it's very docile in the way it handles, stalls out around 33 to 35 MPH straight ahead if you keep the ball centered. Not bad on the top end... full power straight and level indicates 127 MPH and at 75% power around 105 to 110 MPH. All this with a climb pitched prop. The airplane really does not have any bad handleing qualities that we have uncovered up till now. I've got around 23 hours on it presently.

Not planning on other mods at this time. I have just ordered a VDO tachometer as I am still having some issues with the Tiny Tach I have installed. Some folks around here want me to put a speed ring on to add to the nostalgic look, but I still need a Micro Air com w/ built in intercom and Micro Air xponder. Both fit neatly in 2 1/4 inch holes. Then maybe a Garmin GPS or Honeywell AV8r.

I am extremely happy with the Rotec. Looks good, sounds awesome and performs well. The guys in Australia have been great to work with and have gone over and above anything I would expect from an engine manufacturer. Installation was very basic and all info from Rotec was straight forward. Great system diagrams for wiring and plumbing. I would definately chose them again on another project!

I am glad you like the photo's! Check out Rotec's website and look for Joe's Kitfox for more photo's or go to You Tube to see the videos posted. Search for Radial Kitfox and all my other videos are posted by kitfox4c.
