No drama on the wheel pants, Bruce; you DID add another attachment/securing point above the axles, yes? Also, I put 2.5" wheels in there, as I fly off grass and needed the extra diameter.

Have you checked your engine for inverted running? Every OS Surpass I've seen running inverted needed on-board glow to make it totally reliable at extended low throttle settings. I've been told that its all in the tuning, etc. Perhaps; but I've been running Surpass engines for 15 years now, so I have somewhat of an idea how to tune one.

If all you intend to do is crank up, firewall it for take-off, then never get below half throttle until time to land, then maybe you CAN tune one for reliable inverted running. One of the "experts", who made it plain he thought I didn't know what I was doing, ran his inverted 70 Surpass this way. I challenged him to some extended low throttle applications, to show me the error of my ways. He declined...

Anyway, this could be a problem for you. I installed an MPI on-board electronic system. It wasn't inexpensive, and somewhat of a PITA to install (as any on-board system, in the cramped space available in the Matrix, would be), but so far performs flawlessly, and was a near no-brainer to set-up and install. You have to pay attention when soldering the various hook-ups, etc, and plan your installation with a bit of care. But it is not difficult, just very time-consuming. Its one of those deals that would have been easier to do as you built a kit, instead of adding it to a completed airframe.

Good luck on your maiden flights. Add some more aileron throw on low rate; otherwise, set it up as they describe.
