For those of you who are interested, the capacities of the three tanks are are : Saddle = 1,680 ml each (total of 3,110 ml) and the Hopper / Smoke = 1,840 ml.

How difficult was it to remove the tanks?

Fairly easy. You first remove the intakes (Held in place by a wooden ring) and then slide them straight back and out. For plumbing, I'll separate the fuse halves so I can safety wire everything (That a total of 4 bolts to separate the fuse halves).

Lots of progress made! After having to wait for parts due to an ordering error, all tank parts came in, were installed and leak tested. I've also installed the turbine and completed the first start. Fuel system was preforming fine and no issues (again, the Merlin is tuned down to around 170N). Balance wise, I believe the setup came out great, with my three batts (LiFe 3s 3800 and 2 lipo 2s 2600's) she didn't need any weight added to balance at the recommended spot. For those of you who are interested, she came in at 33.5 lbs dry (only UAT Full).

Default New BVM F-18 PNP

I ordered one at Georgia Jets last year. I got it at Florida Jets this year. I have the Diamond Back scheme.
After going through the plane I finally got to get some airtime on it this weekend.
Here are the results. Wow!
I have had a couple F-18s prior to this one. The Skymaster and the small Yellow. Neither flew very well. Both had bad characteristics on take off and landing. The BVM does not. It floats off the runway with no attitude change. It handles very well, even at low speeds. It will stall, but I had to go near no power, no flaps, and almost full back stick to get it to break. When it did, it was severe. Two axis spin, recovered well, but took it 150'-200' to recover. Simple rule, don't do that.
That being said, the stall is the ONLY bad thing about the plane. With full flaps, it lands very slow. Full stop inside of 50'.
It handles very nicely at slow and high speeds. Nice sharp turns, good high alpha, very predictable.
BVM was excellent at helping me tune the airplane. They were at Afterburner and really spent some time with me and the plane. Hats off to Rob Lynch and the BVM team for their support!
This F-18 is like no other. It glides well, even in turns. If you lose an engine in the Skymaster F-18, all you have left is a hole. This one is different.
The difference comes from the leading edge being a lot less sharp than the Skymaster and the vertical fins being more vertical.
I got 9 flights in on the plane at Afterburner, and it is my new favorite jet. I have the stock servos and a Jetcat P-180rxi in mine. More than enough blow.
Fantastic airplane.

That's great to hear! I was very impressed at Super Jets South! Three questions, did you detune your P-180rxi any, are you flying at the stock CG and what was your dry and AUW? Thanks

No detuning the 180. The plane handled it fine. I did two laps at full throttle, but no high G maneuvers. I have been playing with the CG. I am still moving it back. Right now I have all 3 batteries in the nose. I did not weight the plane, but I have not added anything. I am running just the saddle tanks for fuel, the hopper/smoke tank was empty. The control throws in the manual are wrong. I used .75 up and down on the ailerons, it was plenty. Much less flap than called for, and a lot less up elevator with flaps than they call for.
Nothing bad to say about the way the plane flys.

I finally got around to getting the AUW so here it its: 43.00 lbs (19.5kg) AUW and 33.5 lbs (15.2kg) dry (only UAT Full). These weights are with all three tanks converted to fuel and full cockpit.

I enjoyed watching it fly, looked really solid. Sure did not seem to fly like it was heavy at all.

Interesting reports. I’ve flown pretty much all the super hornets out there and they all could bite at flare to touch down.

Looks like BV helped Jet Legend iron that out.

How much flap do you need at take off? EVERY hornet, C, E, F, needs (has needed I suppose) tons of flap at take off so they don’t “hop” off the tarmac.

What tank fittings are those you used?

The tank fittings are interairco and the high flow felt clunks are from nexusmodels.co.uk and are the "HI FLOW BRASS & FELT CLUNK TANK FILTER with Viton O Ring - LARGE".

So I took my tanks apart. There was no debris in the tanks, however, the cluck pickups were 1" too short on the saddle tanks. Almost a pint of usable fuel...at least 1 go around .

Great examples of why you should always check key systems on any build other than your own!

Were they not touching the bottom of the tank? They don't need to be at the very back of the tank.

The videos I've seen of the big one looks like BVM has hit another home run. It's on my want list!
