Yeah yeah, I know. You can reverse the motor wires and spin it the other direction. Thing is the real Tigercat does NOT have counter rotating props so your setup is just as wrong as they way it comes.

True.......;)

The Tigercat is using the same power system as the P-38, the props rotate outwards.

Same power plant has little to do with prop rotation. Rotation is basically the pilots choice.
My Tiger turned as fhh indicated......inboard and the Lightning outboard.;)

In general... with counter-rotating prop top blade moves toward center.

This makes you need less thrustline offset to compensate for single-engine-out.

Notable exception is the P-38, which has an interaction of propwash with the tail that makes it need props to turn the opposite direction.

Which direction should the props turn on my Flightline f7f Tigercat?

Nice looking forward to seeing your work

[Mad Baron]

I still have to unbox my Tcat too many things going on right now plus my workbench has my Cessna on it. I'm doing some painting on it.

[rifleman_btx]

Please let us know what the fix was, im curious.

[Tom]

If you have not called yet, ask for Brad. He is really great with this type of issue.

[Jsala10]

Please call us here at Motion RC when it is convenient for you. We'll get you all fixed up. You may need to simply trim the throttle channel down. Spektrum is famous for needing that.

Thanks

Should I try and calibrate one side or motor at a time or plug them both in and then go through that process? I really appreciate all the comments and replies. Been in hobby little over a year and I’m hooked to nitro and electric planes. Warbirds, sport flyers, EDFs lol. Motion RC has been good and my local hs has been great as well. Wish there was a build for each product and then some common q&a vids as well. Especially for the more “complex” birds lol.

SOS . Can’t get my motor(s) to initiate. They’re searching for signal with that single beep...beep...beep but will not connect. I’ve tried to re-bind, etc but with no luck. Any suggestions ?

Maybe, I have a 10 channel Lemon rx in mine that I got off RC Juice, it works perfectly. Give Martin a call and see what he thinks, the guys are great for Customer Service. They'll get you straightened out one way or another.

Strange, it also might be the receiver. Roll the throttle trim right back, that might help. It bound originally, correct?? If not, I know the Spektrum receivers I've used can be difficult to bind unless you roll the trim back. If it does bind, pull the bind plug and disconnect the batteries, reconnect and see what happens.
Also, once everything is good to that point, unplug again and calibrate the ESC's. Advance your throttle all the way forward (Pull your props first), plug one ESC in and listen for the beep, then roll the throttle back, repeat for the other side. If you're running the ESC's in Parallel and the batteries in parallel, then you can do both at the same time using one battery.
Hopefully we can help you get to the bottom of this.

Grossman56, I need to try an alternate Rx I’m thinking. It’s my first go round with the admiral brand Rx and maybe it doesn’t like the dual motors. I’ve tried recalibrating esc, however the one side beeps twice as in normal calibration but once I connect other battery it automatically goes into the single beep, non-connect mode. The motor strip can only go one way and I’ve ch checked polarity at all points. Even swapped motor to sport upgrade version just to see if maybe it’s the motors...perplexed to say the least.

For safety, before you check things, remove both propellers :Cool:. After that begin testing one thing at a time starting with the most simple of things working your way to more complex.

After you bound the receiver to the radio, check the polarity of the ESC’s throttle servo lead going to the receiver. Make sure that’s the correct polarity to match the receivers polarity at the pins. Ensure proper seating of all servo connections at the board and any servo y-harnesses or extensions you may have used (if you used any).

[rifleman_btx]

Check at the multi connector make sure you have the escs in correctly by polarity. If they are and all your other servos and gear work, make sure you have them plugged into the correct port on the multi connector. Only other thing may be a reversed throttle channel in the radio.
