Good to know, Charlie, thanks! I've got spares in storage somewhere from my old Taft B-25. 'Might also come in handy for the OV-10 I make for you in 2025. :P

HEY HEY NOW, play nice! :)No need to make us wait that long! ;)

Here is another setup. Received the B25 props today. They kinda fit on the P38 shafts but were about an inch or more from the housing. Looked kind of off..I cut the back half inch off the props and they look much better now. Glued some sandpaper to the back of the prop so they would grip the aluminum shaft plate. There was no size or pitch info on the props. They measure 3/4 in longer than stock and look to be a lighter pitch. A- 6 or 4 possibly. Weather permitting I will take it up tomorrow and see how she flies. It does look better with the three blades on it and if anything it looks more realistic with the bigger props. Ground clearance in 1 3/4.

I used the LX B-25 props and their adapter which was a direct bolt on. They don't perform as well as the stock props, I have seen put the complete power system from the FMS Tigercat in mine;)

Presto............. a little search of the thread could have saved you a little grief regarding the use of the LX B-25 props.
Back in Mar 2017 on post#783 I documented the use of these props by incorporating a rock solid prop shaft that didn't require any grinding of the hub or use of sandpaper.
The FMS 1300mm 3D plane motor shaft is your ticket.

Alpha............ the prop mod fly's very well ;)

I'm very interested to see how your mods fly, please keep us posted! These look like they're from the big LX B-25, right?

I have the wings finished but I need to order some more paint since the wings took most of it (a lot of surface to cover). I'll post a pic of the wings tomorrow the paint covered most of the repair! I have some nose art that I am going to send to Callie to see if she can make these up for me.

[Dual Prop Dave]

Started on the paint job on the Tcat today. Got the wings primed this afternoon.

Can't wait to see the final results! :)

Make that magic airbrush sing brother!

OK front nose gear pin. Ordered the spring loaded gear. The center gear does NOT come with a pin. The broken pin I have is a cast metal..thats why it broke. Great design, flared end that keeps it in place instead of the C clip. I took the plastic off one of the old side gear leg, measured it off to the size of the front gear pin, used a die grinder to cut the long slot. To get the flare at the bottom you need an acetylene torch. Tried a propane torch first and it does not get the metal hot enough. Got the metal glowing and popped it with a steel hammer a few times until I got a flared end. Went back to the die grinder and ground off the curve from the flared end until the bottom of the pin is the same diameter but still has the flare at the end so the pin sits flush in the housing. A little of a pain in the ass but the steel quality is far greater than the cast pin that breaks. This pin should last a long time. Hope this helps any of you out there with the broken front pin issue.

Here is the fix with the single prop. Still have to try and make a front pin for the landing gear since they are on backorder for God knows how long

[Mad Baron]

This is how I fixed mine also I called motion rc and sent a picture to Derik.I used a washer from the frame side on a trex 450 and a screw long enough to tighten into the motor shaft

I was thinking of the same fix just have to find a long enough screw to secure the prop

That's exactly where mine failed..the screw ripped right through the hub. I tweaked it a bit pre-flight to make sure they were tight and BOOM. Glad I wasn't way in the air when it happened. The P38 prop shafts work perfect with the two blade prop and the prop nut from the P38 also...I wasted some time and money with the B25 stuff. Good thing is I will have a spare set to make it a 3 blade again I guess...lol Will post pictures tomorrow...

[Mad Baron]

I was thinking today about the prop hubs on my Tcat and I am concerned that the prop hub might fail where the screw that holds the hub to the motor. The reason I am concerned is that I have to remove the props for transport and install them when I get to the flying field and I think that might weaken the plastic hub where the screw contacts the hub.

[prestonowtm]

Prestonowtn-
Can you please provide details/links if possible to the B25 mod for $38?
I am unable to fly my TC due to broken prop hubs that have been out of stock for weeks.
They seem to be a weak point and I would like to avoid this situation in future.
I am assuming you replaced the Props and spinner hubs but what about the motor prop shaft?
I am really discouraged with this situation so any help getting me in the air again is greatly appreciated.

Hey Ken...I wouldn't go spend the money on the mod just yet...I may have wasted mine. Since I couldn't get the hex screws out I swapped out for the motors from a trashed P38 and put the single "speed" props on that I was going to use on the P38. If you can get those pesky hex screws out of the prop shaft the standard P38 shafts work great and they are a stock item....if not... That was the easiest motor swap I have ever done and the single props look great on it. Same size as the 3 bangers but for some reason they look bigger and more scale.
