Yes I put throttle down and quickly tried it but I was running out of height so made decision to put it does in the long grass, does this mean ive over worked the ESCs?

[Evan D]

Sounds like you hit LVC to me. Did you try reducing your throttle to idle and then reapplying low to mid throttle?

[Yellowred]

Hi Guys, I need a little help, flying the Tiger today and I was throwing it about with big full power loops and reversals and low fast passes, after around 4mins flying across the landing strip, I had NO throttle, I was able to let it gently belly land in the long grass with no damage, back at the pitts the throttle was working and both of the lips had 30% in them! Any help would be appreciated, Have the ESCs shut down on me? what's the best remedy as id like to be sure this doesn't happen again? Many thanks

. I used T connectors,2sets, soldered male to female. I then glued them side to side with a spacer between them ..After glue dried Iran a jumper wire across + to + , - to- and then covered with heat shrink.I used 2, 4s 4600 batteries. This way you run both batteries on both motors.

I'm thinking of using the B-25 system from the prop shafts forward, it looks more robust than the Tigercat system. I pretty sure the weakness in the upgraded system that I had on the Tigercat was they way the props attached to the prop shaft. The 3948KV760 motors gave her a big performance boost using the stock ESC's but I'd bet one of the props failed in mid air. She's back in the air running the stock motors/props
but man it performed better with the 760's.

A single 5000 6s will fit easy… the prop blades look the same and I think Aros said that a few weeks back. BUT... the prop hubs and the prop adapters on the motors are very different. The Tigercat blades have two screws holding each blade to the hub back (so does the B-25). Then there are three screws to attach the hubs together and then the props slide over the smooth prop adapter shaft and the center screw holds it on. But on the B-25 first you put the prop assembly, the hub back, three blades and the metal reinforcement onto the threaded prop adapter and then put the cylindrical nut on and screw it down. Then the hub front goes on with a single screw.

Because of this it looks like you can interchange blades but to put the B-25 prop assemblies on the Tigercat you'll need the prop adapters and nut as well as the prop assembly parts. Both have the same square drive. I think you could use the Tigercat prop assembly on the B-25 (not sure why you'd want to as the B-25 has a much better designed hub and retention) but I don't know if you'd wat to put the B-25 props on the smooth prop shaft on the Tcat.

[Grossman56]

That was my first thought. It's tough enough trying to get 4s batteries in her let alone 6s.
The best performance I got out of mine was with a pair of 3948 kv 760's. Sucker hauled! I think it was too hard on the props though, and now with the B25 out, I've been waiting for Aros to answer the question of the B 25 props being a better option. That or the LX B25 props which I have to look into. M buddy OV10 Mr. Charlie Brown mentioned using the LX props, but I'm not sure about the prop shafts.
BTW: I have one of the kv760's in one of my Bearcats with the stock prop and it's virtually unlimited vertical here at 5000 feet.

I need to get in front of the model to see what fits.
I'm just getting out of the hospital and my tcat is at my club.
Funny how your mind works when you're sitting on your a** in the hospital waiting to get better.

I'll need a few more days to recover, then I'll start to work out the details.

Cheers 🥂

[Evan D]

Go for it. Or swap out the motors from the new B-25 and keep the props stock.

[marwady]

Has anyone had success with 6s on this aircraft?

My Flightline P38 files great with a 6s 4000 and downsized MAS 3 blades with stock motors and ESCs.

If I managed to get 6 cells in it and downsized the props, there should be no reason it shouldn't work.

Thoughts??

[Mad Baron]

I made my own parallel adaptors and they work perfectly.

This is what I used to get everything working correctly.

Or if they are Deans connectors, this is what I use. One plug from Amazon, one from MRC.

Thx again

[rekit500]

Link? I just saw the ones with 14 ga wire. Thx

[Spad Driver]

Is this what you are looking for?.
found them on Amazon. Xt-60

[Grossman56]

I posted this on RCG but no replys.
I want to get a cable made to go from 2 4S 4000 xt60 batteries to combine in parallel then out to 2 xt60 4S outputs for a twin F7F Tigercat. I've made one but my soldering skills suck. I could get these but they are 14 ga. And that's a lot of wire..... Who can make these that we trust? I want both bat feeding both motors.

page 66 post # 1310 That's what I did, she still flies off the same plugs. No wires, just two plugs.

Hi Mark, I've seen the FMS version and watched it fly. The difference in size really isn't noticeable, at least to me. I love the scale landing gear on the FMS version but hate the lumpy riveting which is not scale. It was funny because a fellow had received the FMS version for a Christmas present and was nervous to fly his. (this was at a fly in in Riverton, Wy) another member of the club maidened it for him, all the while telling him that since it was a foamy, not to expect too much in the way of aerobatics...I suppressed a comment and watched it fly, looked good. Then I taxied mine out and proceeded to throw it around a bit, just to prove a point
I think really, you can't make a wrong move. Both have their strong points, depending on what you're looking for. It's a tight squeeze getting two 3600 4s batteries in the FL whereas the FMS uses one 6s battery. I like to just watch mine cruise the field now that she's running the stock motors again. Eventually, I'd like to either get another one or reconvert this one back to the KV 760s but I'd like to find a better (improved) method of attaching the props to the shafts, possibly the new B 25 method is convertible, still waiting for Aros to give us some feedback on that. My Buddy Charlie Brown, AKA OV 10 started out with the Flightline, lost it in a garage fire and bought the FMS version to replace it with. If you see him around on the forum, give him a post.

Guys just asking as I’ve always wanted to get the Tigercat but can never make my mind up whether or not to pay double the price for the 1700 fms one, do any of you own one of each and if so what is your honest opinion, is it worth it or not. Noone in any of the local clubs here has either for me to look over them in person. I have the Branco, b25 and p38, love the twin engine planes they sound great. Thanks in advance. Regards Mark.
