|
|
Hey Guys/Gals: I am seriously contemplating building a lightning. I live on a grass runway in FL, so I am concerned about operations off of grass. Does anyone else operate consistently off of grass?
I also wonder about CHT's on the Jabiru. I have a 601 HD which seems to have a cooling problem. I hope I have it fixed, but wonder about the Lightning?
Thanks in advance for your responses.

Hi Lynn,
Good to hear from you again. My experience has been that if you have the inter cylinder baffles and deflectors inside the supplied fiberglass intake ducts positioned properly there is no problem with CHT on the 3300 Jabiru. Most of my experience is with the 3300 (several different aircraft) but I have also flown two airplanes with the 2200 and none of them had CHT problems once you have things set up as I mentioned above. Our chapter's 601XL initially had high readings in the summer months, but fine tuning on the deflectors inside the intake ducts solved that. Another thing to think about is the newer hydraulic lifter 3300s have a higher CHT range than the older solid lifer models, so it is not as critical while you are fine tuning the system.
If you build with one of the Lightning dealers or at Shelbyville they will make sure you get it right. If you build at home, then do yourself a favor and go to one of the engine seminars where that type of stuff is covered.
The Lightnings (and Esquals) operate great out of grass fields, but I would not consider them rough field or certainly not bush planes. Remember you have only 500x5 tires. I have taken mine into all the grass fields in VA that I used to take my Pitts into with no problem. They certainly land slower than the Pitts so the ground run is short. Also, the dealer in Green Landings (gosh I want to say Acres) operates out of a grass field all the time.
One other thought - if your I FLY S MODEL "call sign" refers to a 64 or 65 Bonanza, then you are in for a treat. As nice as the Bonanzas fly, the Lightning is better on much less than half the fuel burn. Since you live in Florida, be sure to make Sun-N-Fun and see the new 2008 Demo. You might even get a ride.
Blue Skies,
Buz
PS: Which airport in Florida?
