Thanks Dennis, I'll give that a try.
I've experimented around with that screw but no luck, your method may be what I'm missing.
In the meantime, I ordered the new forward fuse and left nacelle, but now they're out of the canopy again. Six of one half dozen of the other I guess. Anyway, I can get to work on her hopefully next weekend, get all the paint work going the installing everything into the new parts. It'll sure be great to have her back again, I've really missed that airplane.

Has anyone heard when the spare parts stock for the Tigerkitty are coming? I went to order a new front fuse, left nacelle and canopy but the only thing they had in stock was the nacelle.
While I'm at it, I have the replacement front strut on mine and for some reason, I can't seem to get it to work. The wheel will not compress, I've tried pulling it apart and adjusting everything I can see that might affect it all to no success. It remains ridged, just like the stock strut. Very Strange....

Did you get the front strut figured out? I had the same issue until I figured it out. Loosen the screw that holds the spring, then compress the strut while tightening the screw back, but not too tight!!! It needs to move up and down.

I got her back together and ready to fly again. I just need to go through everything and do a good run up and power check before flight. I bought a new fuselage, props, and a new left motor. Everything else, I was able to salvage and rebuild.. I then spray painted everything and clear coated it.

[Grossman56]

Well Damn!! It happened again last week. Perfect take off with a nice shallow climbing left turn on crosswind and the left wing dropped suddenly, and I lost a lot of power. I immediately corrected to the right but had no choice but to go left to avoid trees and try to get it back on the runway. As I turned back left, it rolled in! When I got it back on the bench, everything was still connected even though both wings were cracked, and the fuselage nose was pretty crunched. I put the battery back in and all the flight controls worked fine. When I spooled up the motors after removing the props, that's when I discovered the issue. The left motor thew a magnet and obviously took a big duce while climbing out on crosswind!! I happened so quick and dropping fast right toward the trees I didn't have time to think of what was going wrong at the time. Others at the field who were watching also started it looked as though the left motor had an issue.
Ordered a new fuselage, motor, props, hubs, and nose gear door and already got the wings and nacelles back together but will have to respray everything all over again.... Arrrrrgh! :woozy_face:

Man that sucks! Sounds like mine. Something let go, i think it might have been the prop or the motor mount, but she went into self-destruct mode after a nice take off and turn. The result being, well, not very nice. The good thing about it is that I've managed to salvage and repair everything except one nacelle and the forward fuse. (new props of course) so it wasn't as bad as it looked at first. She'll be back in service for the next season.

Well... The battery will work but be marginal in C rating and capacity. Remember that the battery adapter will also consume a little energy. If you decide to do it use short wires at least 12 gauge for the adapter. Do a good full power ground test, not just a quick run up, check for battery sag, hot connectors or hot wires. Keep your first flight very short and check how much you used when you land.

Good luck.

Same answer as in RCG...

Morning Tigercat pilots, has anyone flown using a single 4S 5K 60C pack?

[JustPlaneChris]

I wondered about the separate battery configuration, I'll look into rewiring it. I also was surprised by the really long battery leads. Best practice to avoid ripple current is to extend the motor wires, not the battery wires. But, I guess it works!

Ouch, well I'm sure that hurt your pride! LOL. One other thing I would do while waiting for parts, if you haven't already. is to connect both batteries in Parallel. This way both batteries are feeding both motors at the same time evenly. It comes out of the box where one battery feeds one motor each. Not good for a twin prop airplane. Take a look at the pictures of my Tigercat in #2179 to see what happens when you lose power on a single motor!!

I got mine last week, but knew I'd have to put off the maiden until after Halloween (which is a big event at our house). A friend came over Sunday, and I ran it up for the first time to show him. BOOM! All six prop blades departed the hubs! After the shock wore off, I was like "WTF!". Turns out it was stupidity on the part of my mechanic (me). I didn't catch the step in the instructions where there are two screws per prop blade to hold them in the hub, I thought the locater pins did that duty. 🙄 Of course, those plastic pins all sheared and allowed the blades to depart the hubs. No airframe damage other than some dents on the fuselage (right over the 'danger propeller' sticker, imagine that) and my pride. New blades and hubs are ordered, but probably won't be here in time for a weekend maiden. <sigh>

And here I was thinking that after over 40 years in this hobby I'd done just about every stupid trick there was. Nope, still doing stupid things after all these years! 😬

Today. The double trouble behind is two Kaos’ powered by TC motors.

Got my Tigercat back up into the air this morning. Had to replace the prop hubs as a part inside on each one had cracked material and wouldn't cinch down properly on the motor shaft to fly safely.

Stock build, pretty much. Did add some antenna wiring, but otherwise pretty much as I put it together out of the box a few years ago. Don't fly it much these days, but it is always in the "rotation" with the other planes to go up and do its thing. Really enjoy this plane.

Maiden in the books on my Tigercat. Only needed some up trim. Rolls kind of slow even oh high rates. She's a keeper.

Belly of the plane behind the battery area and under the turtle deck aft of the interconnection board are good for the receiver. I have a satellite in the nose wheel well too.

[I-fly-rc-aircraft]

I assembled my 'Cat yesterday.
I intend to use a 7 channel spektrum rx with a satellite but can't seem to find a good location. Where are you all putting your receiver?

Received my Tigercat this afternoon. What a beauty.

Okay, but to your original question. No, it's not common.
