and put wires on the tail section for add strength.
Wasn't to impressed with the flying either. Just my opinion
you can get some info about black horse hear http://www.odieart.co.za/Black Horse.htm
I have had the oportunity to test fly the Sukhoi with OS 46FX and the Cap 232 witha OS 61 FX both with manu. sug. CG from Blackhorse They are not very good. Wing loading very high they both snap to the right at slow flight and have to be flown in rather fast to keep from snapping at touch down also snap in a loop with very little elevator travel. On a Scale From 1 to 10 I'd give em a 3 here is a video of the test flight on the Cap 232
