About 95% done with my first turbine build and now need to get the P70 setup. I recall people running jetA, but noticed on the AMAsite that Jet-A requires "written approval"? Does this involve a lot of red tape? Jet-A is easier to come by and I trust the source more so than kerosene, especially for the maiden.I'd like to use it for the first 5 gallons, but didn't want to waste $ on something I couldn't legallyuse at the field. Also, I know there's a worse smell with liquid Jet A, but that's not really a worry for me.

Thanks!</p>

The only "written approval" I've ever required to get Jet A was making sure my check to Gibbs Flying Service was filled out correctly and signed.

Use it when ever you can...it's the cleanest stuff you will find.

Jet A doesn't require any written approval. Its good to use. No approval needed.

wrex, are you bringing your jet to Waco this weekend? If you have all the equip, there will be plenty of ppl on hand to get that last 5% done and it test flown, I'm sure. Ihave a DX5 that Ibought specifically as a training box that Ican bring - no need to sit and watch if you're that close!

*****You have written approval to use Jet-A in your airplane*****

Print this out and you are GTG!

Honestly, I checked with some of the uppity ups at the AMA and the JPO today because I was intrigued with your question.

Uniformly, the answer I got was "Huh...what are you talking about"? Yes, you can use Jet-A when ever you want...no approval needed.

Unfortunately I won't be bringing the A-4 tomorrow, ordered some kevlar fuel tanks and they haven't made it in yet I'll still be there though, probably about lunch time tomorrow. Probably throw the eflite F-86 in the car, need to keep practicing!!!!

Thanks for the help regarding the jet-A. What confused me is that I found it on an official AMAsafety regulations document(Amendedby EC April 25, 2009 - - 090425 Turbine Safety Regs.doc). Particularly rule #7 - " Fuels are limited to Kerosene and/or propane unless approved in writing by the AMA." Here's a link tothe document http://www.modelaircraft.org/files/510-a.pdf

Yeah...well...I think you were reading too much into the reg. Jet-A is considered kero generally. Obviously there are some differences between red kero and Jet-A but in a generic sense...and in this case it is considered the same.

Now, what about diesel? I see some guys talking about running it...and a couple of new manufacturers saying it's OK to run...but is that legal...per this reg? I have never heard of anyone calling diesel kero...but it is in the same family too I think.
