How many cells on the B50-18S? I ran one on 16 cells in my Midi size F-18 for several months until it split a magnet. I sent a photo to Hacker and they said it should not have happened and told me to send it to Aeromodel. At first Aeromodel said it would be warranted and they would send a new one. After over 2 months and several phone calls another guy told me that 16 cells was too much and it would not be replaced. I told him what Hacker and the first guy said and he finally sent a new one. I've been trying to decide what to do with it now.

Herb,
What is the power output from Jepe fan with this motor/Cell combo? Is this the fan out of you Scooter? To mount the fan in my Scooter I cut two Glass Plates and butted them up againest the rear bulkhead. Then I used threaded inserts in the bulkhead.
The Photo papier glue Jepe suggests is okay in a perfect enviroment but I prefer something more servicable.

Well in the Panther it will be 16 GP 3300 cells to start with. I already have those and they work very well. The Aeronaut Panther seems quite sleek and does not seem to need a lot of power to fly fast.

The JePe fan is less of a load than the Midi, but not by much.

I have run the Hacker B50-18S in the JePe F-16 on 18 CP-1700 cells and lately 16 GP 3300 cells for two years now with no problems. I pull about 800 Watts in this setup (I will give you more accurate numbers later), but I never used a cone so I have plenty of cooling. I also enlarged the front gap between rotor and shroud to about 2mm for cooling. I cool the motor with the fan running at low rpm for about a minute after each flight.

In the Jepe A-4 I have run another Hacker B50-18S on 18 CP-1700 and lately 20 GP 3300 cells, ca 1000 Watts with no problem yet for a year. Again I use no cone, so I have good cooling. The wingloading on the 20 GP cell A-4 is a hefty 48 oz/ft2, a bit on the high side for my taste at least for this plane (low wing, high center of mass).

After about 20-30 seconds these are the measurements I got some time ago for the Hacker B50-18S in the JePe carbon fan:

16 x CP 1700 cells -> 590 Watts 40A

16 x GP 3300 cells -> 790 Watts 44A

18 x CP 1700 cells -> 760 Watts 40A

18 x GP 3300 cells -> 910 Watts 50A

20 x CP 1700 cells -> 940 Watts 44A

20 x GP 3300 cells -> 1100 Watts 56A

The measurements were made over two years so there's some variation in battery state, when the measurement was taken, etc. As usual the GP's hold the voltage much better than the CP's. 20 GP cells is probably over the limit ...

The JePe and Midifan have comparable measured efficiencies, the DS-51 does slightly better esp. the new one.

I am not sure what glue that's supposed to be, I used GE Silicone II from the local hardware store, and once glued in the JePe fan won't come off unless you go in there with a knife and blades to pry, and pull with all your strength ...

Applied rivets to the wings tonite, rather quick affair with approx 1hr spendt. The rivets were like onthe canopy burned in with a thin, hollow metal tube attached to a 25W sodering iron.
Only a very light touch was required to mark the paint.

Guys, the correct term is auxilliary air inlet! On the Panther (same with the Cougar), the speed brakes are made functional and retract into the fuselage creating an aux inlet. Then, they can the be extended for landings and slow flight and the fan is still fed plenty of air. It's a pretty slick setup and is completely hidden.

Martin, what fan are you planning on using in the Panther? Looks like you're going EDF? Very cool!

Yes my Panther will be EDF.
It will be powered by a HW750 fan (I have not decided on motor and cells yet).
Larry manufactured a lighter fiberglass fuselage for me so I think the flight performance will be great.
I will keep you all updated on the progress.

The BlueTailFly scheme is popular alright, and it looks gooood! I hope some more variation will come soon as the Panther have some nice ones besides this.

Didnt get to work on it last nite, will try yo put more time on it this weekend.

Its still cold over here, no snow but ground is rock hard... no good to bellyflop onto.... But once it thaws I'll have my airforce ready to scramble.

Herb, did you have any problem with the decals sticking to the buffed paint? When I painted my Wattage Mig, the stick on decals didn't want to stick to the paint, some of them started falling off or just weren't stuck down really well. Maybe yours are water slide type. I didn't have mine sealed with a clear coat, and I've no idea on long term durability, the little plane died on it's first fligh after the paint job.

Yes indeed ...

Ralle's decals are water-slide, but they won't stick unless the surface is smooth and semi-shiny. Same type as the ones hes sent me for the Rafale.

http://www.modell-lackierung.de/15901/home.html

The procedure I followed is:

0) Clean the gelcoat surfaces thoroughly with isopropyl alcohol.

1) Apply the $3 spray can MM aluminum plate metalizer (2 coats)

2) buff to simulate aluminum panels

3) dust and clean to get rid of any residual aluminum powder

4) Apply two coats of sealer = Future acrylic, from home depot

5) Apply decals to what is now a nice smooth shiny surface

6) One more coat of Future to seal decals (not done yet)

I've learned about Future from reading FSM at Barnes & Nobles while my wife shops for clothes ... Kevin mentioned FSM some time ago as a good sunday reading for better scale finishes ...

The added weight due to the paint job is probably too small to measure on a digital scale - plastic model paints are extremely thin and light. The whole paint job for the Panther cost me about $6 in paints.

The original aluminum finish Panther had a lot of tiny rivets that would take a lot of work to duplicate ... I just used an artist silver pen.

After the flight a guy comes over and says: "you got no blow-in doors!". I say, well there's only so much detailing I can do in an evening...

"You got no rudder either, but we just used those as a foot rest ..."

Anyhow "Skip" had been a Marine test pilot for twenty odd years, initially flying the Panther of a straight-deck carrier in Korea and later flying the F-100 series in Vietnam. Among the 100+ fighter he had test-flown he mentioned a Hunter in the fog over the UK, and captured Egyptian MiG-21's ....

Pilot still alive & well ... The trim was close with 1.5 mm of down trim as per the instructions (the elevator incidence is wrong), it's the first plane that needed no aileron trim at all, not even one click. It's about as fast as my JePe A-4, I'd say about 110 mph top.

Herb, Looks great. Is the Future Acrylic the stuff that you finish a floor with?

Yes ! ... it's a water-based SC Johnson product for vinyl floors. My wife apparently knew about it long before I did ...

It's the first time I tried this Future stuff, all the MM buffing metalizers need a clearcoat to preserve the surface. The Future is very thin and therefore self-leveling.

Ralle used some fantastic automotive paints which are great but are also a completely differerent ball game (priming, weight, toxicity etc).

The Panther looks great Herb. Very realistic. I look forward to seeing it fly.
I'll be out April 17th.

Maiden but no....


Summer came early eh? I guess though by Norwegian standards it never left

Congrats on the maiden Herb, what point of CG did you end up with? I had some down trim aswell on the maiden but after moving hte CG ahead a little the trim was less and pitch moment still good so the 67mm IMO is as far back as I'd go. If using lower power/lower AUW the trim issue might not be any consern.

So where is the video?

Bummer LA Jets or CA for that matter is so far away

Thanks guys. I put the CG at 66mm or so (what Aeronaut recommends), perhaps 1 or 2mm ahead of that - I'm not that good with setting the CG to within two mm's ...

Mine was initially quite sensitive on the elevator, so I reduced the rate a bit further after the first flight. Without the wing sweepback it takes very little elevator movement to get the Panther to pitch up/down. My big 16-cell GP 3300 packs is also seated quite close to the CG, so the moment of intertia about the pitch axis is small.

I use dual rates on the elevator, because with the recommended full throws on the elevator it seems to slow down nicely on landing. Not enough elevator, and you have really looong landing approaches ...

Had two more nice flights yesterday in a pleasant spring breeze ... With reduced rates & some more expo she went quite a bit faster & less touchy on the elevator, verticals, loops & rolls for a good 5 minute flight ... I'm really happy with the way the Panther handles ...

herb you think the intakes are big enough for ROG with retracts?

and is the wing thick enough for them.... sorry to ask if you went over this in the thread.

retracts on this model would be located in the fuse. as the full size is. i wouldn't recommend it though.
i thought about it briefly

Room for retracts is tight, at best. However I've seen one post somewhere of one doing that - no pics or added info IIRC.

Retracts would be cool though and like Gregg I also considered before the kir arrived, thought didnt live long after actually recieving it But its not impossible.

Herb fantastic job! Unclejoe did retracts, added to much weight. I got another kit and planning on adding fixed gear. These are great flying kits. Greg do you still have the scale nose gear from the first kit?

Originally I considered seriously adding SpringAir retracts.

There's a very solid anchoring point at the wing joint, so the installation would be quite solid & reliable. Also the original rear LG was short and stubby, so not much space is needed. Of course up front there's plenty of space for the front LG.

While the LG installation in the twin Rafale is kind of hopeless, it's quite feasible I think in the Panther.

Unfortunately after some research I found only one person in the world that has flown the Panther with retracts, and he told me it turned a sleek good flying edf model into a dog (sic). As a result I did not consider the conversion any further, and must admit I like it very much the way it flies right now ...

Here's btw a picture of a nice scheme that does not require a major complete paintjob for the Aeronaut Panther (which come pre-painted in blue) - but still livens it up quite a bit:
