So, last weekend, mid October 2006 it was off to the field, make or break time as far as I was concerned! The afternoon couldn’t have been better to test fly the Rex, almost no wind, bright and sunny. Probably the last warm day we’ll have this year!

Having done some more reading on RunRyder about throttle values, the first thing I did was alter the throttle curves in Normal and Idle ups as follows.

Normal:

0, 65, 90, 90 and 100

Both Idle ups:

100, 90, 90, 90, 100

I like to fly with the hover point at 75% stick and I found with the previous value of 85% the stick seemed too high. The new settings worked out just great with good head speed, no idea what but I’d estimate 2,600 plus.

Crunch time. I spent the first few minutes of the first battery trimming the Rex in Normal and Idle up then off for a circuit with a perfect result. No glitches just nice, smooth and powerful!

The second battery was used just throwing it around, stationary flips, rolls and piros in all directions. It performs these moves with ease and I felt at home with the heli immediately. I need to adjust the gyro gain a tad as the tail was coming out of line a bit, and I noticed that because the Rex is so responsive you have to be precise with your inputs and it can get small very quickly! Just what I need to improve my flying skills!

So, what’s it taken to get to the point of having a machine that flies the way I want it? Let’s discount the time factor and look at the costs and equipment installed:

I said at the beginning that Micros can cost as much as nitro helis at entry level, and there’s the proof.

Having said that, The Rex is considerably cheaper to repair when things go wrong, and I intend to push this heli as far as I can to advance my flying without putting my Raptor 90 at risk.

I hope you’ve found this section useful and I’ll let you know how I get on with the Rex in the “Progress” pages of the site.
