HPI, Losi, Futaba: a Hattrick!
Three brands, three breakages…
I went racing today, touring cars, outdoors at SHMCC. My aim of the day was to play with the set up of the Tamiya TRF415MSXX, I have removed the roll bars, and wanted to try it without.
I stiffened up the springs a little, and it generated a lot more grip than with the rollbars, much more stable. A little too stable, I was struggling to get it to turn in, but some fiddling with springs, droop and roll centres and I think I sorted that.
But, the day was marred by breakages. I seem to have damaged my Losi Xcelorin 17.5 brushless motor, it ‘went soft’ the last time I used it. But first run today and it was great, strong, fast, everything seemed fine. But 2nd, 3rd and 4th runs were ruined. A solder connection came off in run 2. Run 3 I thought it was a sensor lead. Run 4, it confirmed that it was the motor, it would do 5 laps, then come off the track too hot and no longer working. That’s dead then.
I borrowed an identical motor for run 5 (final 1) and that ran fine, so the speedo was okay, thankfully. I borrowed another brand of motor too, a Trinity DUO 17.5, and that was very strong indeed in run 6 (final 2), and had a great race, popped in a 19 lapper, no mistakes and a nice close race with someone using an identical motor.
The final run of the day I did half a lap and it stopped. Closer examination and it looks like the Futaba receiver isn’t working.
And then, I took my HPI E-Savage, and a friend broke the rear differential! It’s supposed to be a weak point, so I’m surprised it’s not broken before now.
Still, I had a good day!

Oh well Simon, you still got away with reverse-connecting your sphere…. a fate that would usually cost someone 200 smackers.
Shh! That’s a secret!
woudln’t worry too much, the Sphere’s are pretty resistant to the dumb connection :p
MRT’s on the other hand go pop instantly
Reminds me, I need to send mine back to get fixed…
