Will 4 JR DS 8231 (88 oz/in) enough for Kangaroo elevons? I have a JetCat 120 with speed limiter set at 175 mph. I was going to buy 4 new 8411 but I already have these 8231's with my 10X.
Thanks

Those are plenty.

I flew my first roo with 2 JR 4421 and switched to 8411. With 4 servos in the wings you will have no problem. Even with P-120 power.

In the new roo I use two 8411 and two Hitec 5945, just because the were in my hobby-room.....

The 8231 are plastic geared, that would be my only comment. The 8411 are metal geared.

I have used tw0 8411 on my roo and two 5945 on my Hot spot with a P120 with no problems....so far!!

No problem as far as I see. My Roo has 1 each side 4721 servos, the only problem I had was hitting my retract switch while back taxiing @ superman last year. Kent Nogy replaced the gears free for me to keep flying that weekend.
