Removing Main Wheel

I may have to remove my wheel to fix a tube leak in the next few days. All my manuals are at my hanger, and I was curious tonight on how to remove the wheel. I seem to remember than the rim is bilted…Continue

Where do I jack my plane?

Started this discussion. Last reply by Bob Pustell Jun 3, 2014. 1 Reply

I discovered a flat tire on my 601XL-B this am. I did not build plane, so have never jacked the plane up.  Looks like I can grab near the brake or up high.Anyone with pics or sketch of jack points?Continue

Changing tube on 601XL-B

Posted on June 18, 2014 at 5:44pm 19 Comments

I am having difficulty getting my new tube settled into the 2 Grove Rims. Does anyone have advice or better yet pics on proper methods to change the tube on my main tire?  My valve stem sticks out too far, and rubs on the wheel skirt brace. I wish there was a builders video or You Tube shot on doing…


Charging Issue

Posted on May 5, 2013 at 8:52am 6 Comments

More questions from the rookie.


Still playing with heat issues, but a new opportunity has surfaced. While taxiing to the active, my battery charge indication shoed low voltage, fluctuating into yellow. On run-up, the bar still showed slightly more than 12 volts. It usually reads 13.2 or so. I went back to tie down, and quit for day. Later, the battery would not turn engine. On charger all night.


Does the Jabiru have a voltage regulator that may be bad? If so,…


Oil Baffles

Posted on April 18, 2013 at 1:07pm 0 Comments

I received 2 oil baffles from factory. There was not an illustration, drawing or picture on installation. Does anyone out there have details on proper means to attach the baffles to my Jabariu 3300 on my 601-XL-B? (Part numbers 33-B, and 33-B1)

I did find it ironic that the decals for 601 wing Mod that were included had 2 pages of installion details, yet nothing on baffles. Contacted Jabariu, and they were not helpful, as they said parts were not theirs.

I was just curios.  I replace the 12 row oil cooler with a 24 row cooler, and it dropped my oil temp from 240 to less then 170 on a hot day.  My CHT's run around 290 at 75F and on a 90F day, reach 311 to 315F. I don't like to fly it that hot. It seems I have to do more head torquing and valve adjustments when I fly it hot. ( I only torque to 20ftLbs now ).  What did help on lowering my CHTs was to replace the rubber baffle seals on the lead edge of the fiberglass scoops with wide material.  I used a baffle rivet and trimmed the front edge to fit snug inside the top cowl air inlet openings.  It made the top cowl harder to get off and put on, but made a difference of about 10 degrees.

Actually the picture is in the comment section at the bottom.  There is also a picture of the mounting bracket.  Note that my 601 has the early cowling and the automotive oil cooler.

Look in this blog post for a picture with both the old and new cooler.

Thanks for the info on Deer Valley -however, since you are in the area, I'm not, they had a mid air collision there last week-believe it was in a practice are - out North somewhere - perhaps by a state road. That cooled me off on the area somewhat. As the NTSB results are customarily delayed, was insufficient radio contact of a theoretical importance? Did one A/C have an instructor & student? Are any forthcoming details yet available?

I have been considering retiring in New Mexico or Arizona-have been to Casa Grande for Copperstate-in that you are in the Glendale area, hangar availability per my search so far, no access. 2 yr. waiting list in Coolidge. Any input appreciated. See your photo. Is it safe, via carport-shade 601 photo. A close friend of mine-his 182 was locked, chained, stolen. We believe it was taken to Mexico-has long range tanks, sat outside like your 601. Looking for hangar space in next 6 mos. Advise please. Have 601XLB & another E.A.B.

Hi Don

yes ill take some tomorrow when im down at the airport

I sent you a private message.  But, one option is cooling louvers that get installed into your cowling.  They create a negative pressure area and can dramatically increase airflow inside the cowling to cool CHT and oil temps.  Of course, your baffling and everything must be sealed tightly.  This won't fix the problem if there is an underlying issue with baffling, etc...but we have numbers from a lot of RVs that have been cooled 30-40 degrees on CHT and 15 or so on oil temps.  Also, we have data on some zenith aircraft that are also favorable.  The temp decreases are not as dramatic, as the speeds are less, but they are still very noticeable.

Go to for more info on our cooling louvers and other products!

Hi don
I have a 601hds i found that the duct on the cowl wasnt directly on the oil cooler we reshaped the cowl so the oil cooler has more direct flow and this seems to be helping
