Default Precision Aerobatics 35% Extra 330L Build and review

Hello, I am starting a new thread dedicated to the Build, set-up and flight of the Precision Aerobatics 35% Extra 330l.
I ordered the airplane from Troy Built Models in Florida. The aircraft is expected to arrive next week 24-29 October.
If all goes well I intend on flying this airplane by Thanksgiving.

Please try to keep this thread related to building, set-up and flying this beauty!

They have a beautiful Extra, I love the colors and have been thinking on getting one also. I have a 3W 120 that I want to use and this seems like a good fit. What will you be using? Have you already got your setup planed out? Please post lots of pics when you get it.

Thanks

Kevin

The airplane is very well constructed like the Extreme Flight Yak's (light and strong, all lazer cut with premium wood) and it has many features that are awesome and in my opinion user friendly.

Here is a great idea they have lazer engraving in the wood with their logo (looks cool) and they already have cut a groove on the servo holes for the servo wire (finally somebody thought of this!!!!)

The inside has trays with multiple locations for item placement and velcro to hook and loop your electronics securely!

Way to go PA!!!

The PA Extra is huge, look how it makes my big screen tv look like a 13" monitor
Just kidding, but it is huge!

Kevka,
Better hurry and get one because I know that when this airplane gets out on the local fields and people see them in person there is going to be a waiting list bigger than the one for the EF Yak's. This airplane is definitively underpriced now (in my opinion) and its a specialty plane that has been thought and designed by somebody that knows what is going on!

This airplane is superior in construction and design to any other plane (even the kits).

Those are very impressive numbers (25-27lbs, 2128 area) [8D]

Let us know what the final AUW is.

I am sure you will love it!
You will also be surprised that there is a lot of work done already from the manufacturer to ensure a great building experience.
I recommend you get with Gene and have Him send you an estimate with all the stuff you will need to finish it!
He did that for me and saved me a lot of time and money (by not buying stuff I don't need).

Keep in touch I have just finished hinging the elevators and will proceed to the rudder and wings tomorrow!
will post pics of the elevators later.

Hey everyone.
I am very close to finishing my PA Extra....Hopefully late next week
Setup:
BME110 on stock BME mufflers
4.25" Petes carbon spinner with 28-10 Mezjlik
Carbon Gear from Gene at Troy built (Not sure what it fits but Gene knew what to send me as he always does.)
Graphtech tailwheel
Carbon Wing tube and Stab tube direct from PA (I believe Gene now has these or will soon)
Carbon Control Horn set from PA (These are awesome. You really want to buy these. I think Gene has them or will shortly They are built with the correct height difference for the Inner and Outer Ailerons and the geometry is perfect.)
5955's on Elevators
5945's x 2 on each aileron
5955 x 2 on Rudder
TBM LiPo batteries and MPI switches
35% Chip Hyde Helmet Head (An awesome looking pilot figure that weighs 1 oz ! )

This plane is as nice as everyone claims and it is huge and light. With my setup I will have to move the batteries and the rudder servos as far forward as possible for balance but it will work out fine and the plane will be stupidly light with the BME.

I will post pics when it is ready to fly showing locations of equipment, etc.

If you want to use the BME 110 (I know Shaun thinks this is too much engine for the plane but that is why I have a throttle stick and a 10X radio with a proper throttle curve you will need 3/4" of Spacer. I made mine from 3 layers of 1/4" ply and then bored out the center with a large hole saw. The BME is not meant for standoffs and needs spacers to insure the load is spread over the radial mount.

I moved my Gas tank to above the wing tube to insure it will be on the CG. THe stock location places it completely in front fo the tube and I did not like that. I made a simple saddle mount over the wing tube with a tray and will use the supplied Velcro to secure it. A very easy mod.

Have fun....

Nice set-up there topend. I 've got my eye on this plane and would set it up pretty much the same if I end up getting one.
Please do get some pics for us and let us know how it balances out.

Thanks, Jim

What is your dry weight with bme110 and cf stuff? I bought the plane planing to use more or less your setup (single 5955 for each aileron and rudder) with BME110. However after getting some feedback about the engine (heating issues and lack of proper service..) could not decide about the power yet. Did you have experience with 110?

Topend,

What are you using to power your receiver? are you using a powerbox or running 2 receivers?
Also Do you think it is necessary to have 2 servos for the rudder?

I do have expereince with BME and I have no problem with them. You do have to be careful about proper cowl ducting to keep it cool but other than that they are awesome engines. I have always found Keiths service to be adequate although nothing linke DA. He is pretty much a 1 man show and warranties and repairs can take a few weeks...I always have more than 1 plane to fly so I do not worry about it too much. He stands behind his engines and makes am amazing product. The weight and power are worth it. When you can rip a 28-10 at 6800+ RPM it can't be all bad.

I would not use the single aileron servo. If you are you will at the very least need to make a new servo bay in the center of the wing to accomodate the servo. This plane has huge ailerons and a 106"+ wing span. It is not so much the strength of the 5955 that is in question but the length of the control surface that is being operated by a single servo from either the extreme inboard or outboard location on the wing. It is a built up wing and as such that aileron needs to be supported inboard and outboard to keep it from twisting and to insure proper centering. The servo locations on this wing are only acceptable for dual servo use.

Of course I could be totally wrong

I really like those numbers with the BME,
however since I do not have very much experience with a big plane and or a big gas engine. I decided to go with the DA. I am also not a good engine tuner .

I think it will be an awesome plane anyhow. I really like how many things and details have been though out for you.

What I plan on doing is to have the Gas tank in front of the wing tube and the smoke tank behind the wing tube. Both 32 oz. that way I can take off and do my 3d stuff tail heay with smoke and land nose heavy without smoke.

What you think?

Thanks for the feedback, it is really appreciated... I know your point about the ailerons, I am using singles on my 2.6 comp-arf extra (it is not a built up wing of course). PA recommends using two servos also but Gene -troybuiltmodels- suggests one. . I like to give it a try anyway.

I don't like that idea at all....Since you won't be using Smoke all the time put the smoke tank in the stock tank location in front of the wing and put the fuel tank on the wing tube. That way the plane will always fly consistent when you are not using smoke and you can do what all the big boys do and add a chunk of weight to the tail wheel when needed for extreme 3D when the smoke tank is full. The location in front of the wing tube will not create a bad nose heavy condition as it is so close to the CG but 2+ pounds BEHIND the CG will be an issue.

Ideally they should be side by side. I did not try it but I bet you can get a 32 oz gas tank and a 24oz smoke tank side by side on top of the wing tube if you tried.

You make perfect sense to me. I have a 24oz and will try your idea.

Are any of you going to use the Power Box. I was looking at some and did not know there were so many different ones. The one on Aircraft International is a 40/16 Evolution for $250. Will this be enough for my set up? Does this one have the servo matching for the ail's and rudder. I am using 2 on each side and two on rudder. I don't really think I need one that will drive 24 servos. Do you guys use a choke servo or do it manualy to save weight? What kind if any of a kill switch system do you use on a 35%. On my DA 50 I always just used the choke servo as a kill.

I have been using a SmartFly ( http://www.smart-fly.com/Products/Expander/expander.htm ) Power Expander on my Comp-ARF 2.6 YAK.
I'm not sure how much it is really needed but it certainly can't hurt....If you are using Hitec servos you do not need the matchbox provision of many of the really expensive powerboxes because you can program them directly. For $99 + their BatShare HD interface it is a very good deal.
