Official FlightLine RC 1200mm F8F-1 Bearcat Thread

is that control box really necessary? seems like something else to go wrong...after all it was made by the lowest bidder I am sure

[crxmanpat]

All outputs work fine on mine. Elevator and rudder don't go into the box, just plug them straight into the RX. I mounted the box on the upper rear wall, and put my RX right next to it.

I only plugged the gear and flaps into that box and used a separate y harness for the ailerons. Mine had 3 outputs (gear, flaps, ailerons) but the aileron output didn't work. The rudder and elevator go directly to the receiver.

Dan,
The assembly manual on page 7 clearly shows that there are two sides on top(outputs) where you see the FlightLine logo and then opposite of that logo on the end of the case is five(5) connectors(inputs) that you hook leads to from the receiver. Can't understand your confusion :huh:

[Grossman56]

Okay guys, please explain to me what the heck you do with the controller box. Is one side input and the other output? the only two wires coming out are flaps and landing gear, the instructions don't explain anything about this.

flying off grass most of the time il stick with the non scale standard four blade

[Grossman56]

Love that prop F106, that looks very scale!
I'll keep that one in mind when we can find a prop source. Anyone finding them, please post!

Hi dkalwishky, from which point are you measuring your CG? I flew both preproduction and final production models with an Admiral 4s 3600 or 4000 pushed all the way forward for perfect balance during flight.

i measured 85mm right up against the fuselage. Once my gear problem is fixed I'm going to fly it as is and see how she flies.

I just used the stock shaft and removed the key from it with a file. After tightening down the prop nut, it isn't going anywhere, key or not. On the same topic, do you know of another source for these props? I was going to pick up a spare, but they appear to be out of stock everywhere.

Nope...............I've searched all over and nothing. As I said above, Dragon (was the first) and Banana are the only sources for HSD equipment.

[F106DeltaDart]

Hey Delta,
Whose prop shaft were you using?? I know that the HSD one for the Skyraider doesn't have the same bolt pattern for the FMS 580 motor and the FMS prop shaft has a smaller hex @ 9mm versus the HSD hex @ 13mm. I've been in a futile search trying to find an FMS shaft that will work on my HSD Skyraider since none can be had from Dragon or BH at present.
Thanx,

Got in 3 flights on the Bearcat this morning and it flies great! Mine is modded with the FMS 580kv motor, 85A ESC, and the HSD Skyraider prop. The torque from the big prop was manageable without too many issues, and performance is very good. My flights were between 5-7 min depending on throttle usage. Cruise power is around 50%, and the upper 1/3 throttle really kicks it into gear! Climb was unlimited as far as I could tell, it just kept on pulling. The CG was a bit tailheavy for me on my first flight, and I moved it a bit forward until it balanced at the end of the silver exhaust panels. From then on it tracked beautifully. This one is definitely a keeper!

[Grossman56]

Looks like a great plane, can't wait!!
Is anyone contemplating the speed upgrade but keeping the four bladed prop?

[Grossman56]

Good to know Ryan, thanks for the help.
If its somewhere between 85 and 90mm, it will be a matter of finding your own sweet spot.
I'd like to hear some opinions on battery placement from some of the guys as I do it more from memory than anything else.

I got my Bearcat assembled today and ready to fly however I have two problems. The righ retract failed after a couple of cycles, I've sent an e-mail to Motion to get it replaced. The second issue was with the CG, the manual says 85mm however with an Admiral 3600maH shoved all the way forward the plane is still tail heavy.

For you guys flying the preproduction model, what did you use for a CG?

I'm flying with our 4000 all the way forward and she's a jewel as you can tell from the video. My fat fingers get more of a 90mm reading inverted with gear down.

[Grossman56]

Yeah its interesting because I reviewed Ryan's flight video and he says that he had his 3800 all the way forward as well.

Hi dkalwishky, from which point are you measuring your CG? I flew both preproduction and final production models with an Admiral 4s 3600 or 4000 pushed all the way forward for perfect balance during flight. I fly Admiral 3000s many times as well, just pushed all the way forward. The sensitivity creeps up a bit but in inverted flight and in power off inverted dives the model still didn't exhibit a tail heavy behavior.

Please expect a response from our CS Team when they return from the weekend tomorrow. They'll get you sorted out.

Thanks for the continued opportunity to earn your business!

[Grossman56]

Hmm, I'll have to see if Ryan will chime in on this, stand by....

P.S mines due here tomorrow,
