I have 4 Panthers at my club field, we all fly at 70mm cg - they fly great, no issues and certainly not at all a handful.

Good luck, keep a little power on for landing and your nose down to avoid the balloon.

The suspense is killing me! I so hope Pavcon had a successful flight - he deserves it.

thank you topher.. That really helped.
Kind of succesful maiden. I balanced it around 68mm

The ballooning was still there.. bUT .. The plane felt tailheavy from the beginning. So i think it might not been balooning might be a case of the cg. The plane was actually flying very stable i made a couple of low slow passes. I was very nervous and those passes boosted up my confidence that i could land it. I didnt try the flaps.. I just came around one more time and came for landing. I decided (actually i was adviced to come a bit hot..) i came in with 1/4 throttle maybe a tad more. as soon as it touched dow i cut the throttle and voila. I borrowd the cg machine from a friend and im going to balance it even more forward. Im just glad that it came down in 1 piece. Actually the landing looked beautiful. Both mains touched first rolled a bit and then the nose touched to taxi it back to the hangar.
Oh and also the takeoff was so scale. I barely touched the elevator. Much different than the first one. Only difference was the stressed pilot.

So Glad you had success - great job, your fingers must have been doing a dance for the whole flight! (one of those times when you hope you can calm down enough to land!)

Keep up the flights, I'm sure you will find the comfort zone.

you can't imagine how my fingers were and how my heart was beating when I was making the final approach for landing.
there was also a strong crosswind that was adding to that. fortunately I corrected the tail around 6 feet from the ground and came in nicely.
now need to shift the lifepos position to shift the cg even more forward.
oh.. I also think that when I droped the gear for landing the cg also shifted even more forward and helped a bit.
I'm gonna balance it at 60mm this time and see what will happen. if it's too nose heavy then no problem. 50% flaps can correct this. and a bit up trim..

Whoo HOO! Congrats on your maiden. Isn't she a great plane. I think you'll be flying her more and more. Soon, you be so used to it, you won't even remember this whole ballooning thing. I rarely even notice it anymore. : )

thank you Dave.. I will move the CG even more forrward and retry, most probably on Saturday
I think that balooning I experienced in mid air it was due to CG because the plane felt tailheavy during the entire flight.
on another update my Cougar arrived today
2nd RClander plane.. and I'm thinking about the Hawk 64mm as the next one..

Pavcon,

I am so pleased to hear about your successful Panther maiden
flight! You sure deserved your success with all the issues you
have experienced in the past. I look forward to seeing a video
of your next flights.

Hey Guys, Watch This.......

I so pissed I ordered a upgrade retract system for one of my Panthers. Really nice but one of the mains failed right out of the box. I'm sure they will make good on it but that just held up the install for about a week or so.

FLY IY, BREAK IT, FIX IT,
Hooooooot! GWR Hand launch Panther just arrived from RC Lander!

oooooo, it is so tidy compared to my crappy blue V1.

It is going to stay in the box until V1 is thoroughly and permanently retired.

speaking of that and my "arty" video that nobody could doppler.......I am fitting my EagleTree to the 1.5kW Panther for a flight tomorrow (subject to weather). I have the pitot tube and altimeter ready, so we can see what speed it does straight and level.

just got to hope the Deans connectors hold up to 109A on the ET unit (which is only rated at 100A). If it blows, it will take the UBEC with it.

EDIT

In fact, what I will do is set up the pitot and altimeter as stand-alone units on a separate small lipo, with out recording the amps/watts/volts. That way I will be safe.....
