Hello,

Finally got the Contra fitted to new Amethyst for WC in Muncie.

I have attached some pics, showing the setup used ( Amethyst Mod-YGE 90-Neu f3a-Thunderpower 25C 5000s and 4400s- 22x20back 22x18front )

Had 6 trimming flights Friday. and the power is fantastic, much more vertical performance then similiar setup on Amethyst with Hacker 13xl last year.

I had 4 flights on this model last month with Hacker 13xl before I fitted contra, waste of effort! Completely needed to start from scratch with trimming, throws were dramatically reduced.

Far less rudder needed, less right aileron needed, NO mixes needed ( may need a touch in downline but wasnt calm enough to be sure )

As previous posts show it definetely makes surfaces more sensitive, nothing that cannot be tamed with expo and reduced rates, will just take some stick time to adapt.

Sounds fantastic in my oppinion,more pleasing to my ear then previous contras I have heard, well within sound check barrier.

Had 3 x p09 flights and uses similiar or less current draw then 13xl mono prop.

Weight penalty is negligible, I reckon about 85g net increase from my mono setup, easily absorbed in modern airframes.

Overall a fantastic combination and for sure is a step forward from anything I have previously flown.

PS The first pics show the mounting system Brian Carolan has come up with , the 3 bolts on triangle mount can be openned and the complete unit ( inc. motor ) can come out through front, in about 30 seconds, very wel thought out.
