Here is an option . I send all rotating assemblies to them before I build. You'll have to disassemble the engine first. They charge a minimal so I would send all of it.

Jeff,

That is a very cool process. No pun intended. If I bought a DLE 222 and sent it to them they would take it apart and use the process on all the components and then ship it back. I realize I would have to supply them with all new gaskets etc. Is this what your saying. It didn't say in the video.

Kelly,

All engines have their problems and after getting a price from a Hong Kong distributor for the DLE 222 NIB of $1298.00 I might just try the one anyway. I have always been a gambler.

Winston,

We will be very close on the final weights of our birds from the way it looks. I think it's 72 lbs now.

It has to be inspected if it's over 55lbs. However the rules have changed a little to make it easier for the 55 to 77.2 pounders to be inspected. My Super Chipmunk will be around 60lbs

Here is a short thread on the subject

It was my understanding that, under the new rules, it would only have to be inspected from 77.2 to 125lbs. The non inspection limit was raised from 55 to 77.2. Is this not correct?

NCIS

I still seem slightly confused. Plus where does a builder find an inspector to watch the airplane fly? I'm in Wisconsin and I fly off an old runway at a farm that the farmer/Owner used to fly his Cessna 172 off of and continues to maintain it for us. How do I find one that will come out there? The runway is 50' wide by about 1000' long. It's smooth and better than any clubs in our area. Were just lucky to have it to fly the big birds at. Most of my friends fly off our club field which is an old dumpy landfill. Pot holes everywhere. It's OK for 3D where you can take off in 20 to 30 feet but not Warbirds with retracts.

Self / builder inspection up to 77.2lbs for a prop plane.

NCIS

Gary,

You mean up to 77.2 lbs all I have to do is inspect everything myself like check linkages, bolts, prop tightness, and etc.? But what about the flying part where it says I need two observers and one has to be official. Does that person need to special be or would our safety officers be enough? They are older than Moby Dick so they may not be able to see much through their caturacs! We have two in our club and they would be able to watch it fly at my other field with the nice runway.

Thanks for your help,

Frankly, I'm not sure about that part. It seems to indicate so, but your not applying for a waiver, up to 77.2lbs, only if it over that. Why would an 'official' inspector be necessary?

Most giant events have already made provisions for this in advance, so I don't see it being an issue for you.

TomCrump

Barry. If you are going to Toledo, you can stop by the AMA booth, and ask your questions there.

I'm sure that they will be more than happy to provide the assistance you require.

NCIS

Thanks Guy's,

I want it to come in below 70 lbs if possible and no higher than 75 lbs.

Barry, You would disassemble the engine and send them the parts, then you re-assemble. unless they changed the minimal is 75.00. thats why I say go ahead and send it all. Jeff

Barry, between 55 and 77.2 pounds, you can do the build and inspect. But, to certify for flight, you need 2 observers. They must be a CD or an LMA inspector. BAsically, it makes it easier as there are a lot more CD's than LMA inspectors.

Jeff

Actually, according to the way I read it, you can serve as your own observer, so long as you are not the pilot as well. You would only need one CD or LMA in that case. Two flights are required for certification.

Gary, that is true, but I just can't see (me) anyway, leaving the maiden to somwonw else......so I need 2 additional

Jeff

ram3500-RCU

My Feedback: (221)

Frankly, I wouldn't do that. I would fly it privately for the maiden and a couple more to check it all out and make any adjustments. Then set up a certification session with your CDs or whoever.

Speaking of Corsairs I can't think of leaving it to anyone but you either Jeff!

I always maiden my own stuff, but not necessarily in front of a crowd.

NCIS

OK lets speak my language. I would like to know what a CD and LMA are to start with. I haven't got a clue because I have never had a plane inspected or had to have observers either for that matter. I have just built them and flown them but all were under 55lbs. Help me out because I don't understand the abreviations.

Thanks Guy's for the replies,

CD = Contest Director
LMA = Large Model Aircraft

Large models need to be inspected to be given a waiver for coverage under AMA rules.

I have been busy working on how I wanted to set up the flap servos and came up with this solution. I am using 1.5" aluminum servo arms on the servos and because of their thickness a Z-Bend won't work so I will use 4-40 pushrod keepers with the bottom leg cut off and use it to keep the pushrod from sliding out of the arm. I will flatten one side a bit with a file and then when it's ready for final assembly use locktite on the 4-40 hex head machine screw that holds the rod in place. This is commonly done on smaller planes for the pushrod to slide into and when it's adjusted correctly the screw is just tightened. It wouldn't have a chance doing that on this size plane especially for the flaps so it is just being used like a wheel collar. I included a picture of what I'm talking about. I am just testing the flaps with Futaba s3151 servos with 54 oz. in. of torque but the final servo being used will be 330 oz. in. of torque or more. I have to save up and buy them when I can. But this shows me they are operating smoothly without just torque doing it.

Hey Barry, On something as large as you got there. I would look into using carbon fiber rods. AbellRC has some neat 4-40 carbon rod ends that would work great. Then you can use ball connectors for a slop free set up.

Here the link

Don't skimp on something this big
Later,

I would not use EZ connectors on any surface of a model of this size.
