    Talion Front Driveshaft Vibration

    Hey, I'm speedrunning my Talion EXB 6s. I'm having a really tough time with the front center driveshaft. At high speed, it is vibrating so badly that the diff input bearings keep shattering. I'm running M2C diff input cups (true and balanced), Scorched Titanium driveshafts (no bends etc..) , and...

    TP Power motors. Please explain.

    So I now have a new Limitless V2 that needs a power plant. I started researching TP motors but I now have more questions before I hand over my cash and order it from overseas.

    I received my armma limitless v2 and spray painted it and started making custom carbon fibre parts.

    I am probably going with the 8s Spektrum setup with the 1250kv motor and 160 a Esc they have on their website https://www.arrma-rc.com/de/product/1-7-limitless-v2-speed-bash-roller/ARA7116V2.html but I have no clue at all which transmitter I should go with since they have all parts to complete...

    Radiolink Receiver Options - Speed Run

    Does anyone have experience with other RadioLink Receivers? I'm using the Radiolink RC6GS V3 on my Limitless. I have a new build coming with an Rlaarlo AK-917 and need to add the radio. The current receiver, shipped with the transmitter, is the R7FG. Which is overkill with 7 channels. There...

    Talion Speed Run Tires For Talion EXB

    Hey guys, I'm trying to see how fast I can push my Talion EXB on a stock ESC and Spektrum 2050kv motor. I'm hitting 85mph consistently, without any heat problems on Sweeps Road Crushers. These wheels are nice, but they're insanely heavy. I'm considering 1/5 GRPs, but I've heard they're heavy...
