RE: KINGCAT HELP!!
Interesting, mine has UP elevator with Crow configuration....just slow it down and when it starts to drop a little on final, a little power will keep it nose up until I land.
Have you set it up per the BV instructions (amount of flap/ail/Elev for crow)?

RE: KINGCAT HELP!!
ORIGINAL: jetman-RCU
Anyone with Kingcat experience I need some help to figure out a problem.. I have a fairly new KC and just put the first couple of flights on it.
The first flight required about five clicks of down trim and about four clicks of right trim, after which she flew great. So here's the problem, the landings are difficult to say the least, I get a porposing effect and I have to fight it all the way down. I do have the crow , which is full flaps and up ails and down elevator, I took the elevator out after the first flight.
It seems like I can get it slow enough or fast enough, we clocked it about 70mph on final.
I thought it could be a balancing problem but it fly's great, I have seen many KC's land so easy but not mine,can anyone offer any advice?
Thanks..

2) Practice slow flight ... if you try to land it too fast you will get pilot induced oscillation. You must get it slowed down and land it with a little power.
3) Keep your pattern in close and your approach flat.

RE: KINGCAT HELP!!
The previously offered advice is right on....I might be able to add something though.
If you have a JR10X radio, I would suggest using the "Flight Mode" feature, as it is a great pilot workload reduction tool.
Mine is set up as follows:
When in the landing pattern going upwind, I always extend the gear first, then lower the flaps to the 15 degree position. The flap setting turns on the flight mode, adding a small amount of up elevator compensation. On downwind abeam of myself, I lower the flaps to full, and an additional amount of up elevator compensation is added, and the ailerons jump up adding the "Crow" feature.
(The first time you fly the airplane and activate the flight modes, you have to trim the airplane for each of the configurations).
The trim settings for each configuration is then in memory, and will be reactivated when you select the flap position of your choice.
Afterward, you don't need to re-trim each time you change the flap and crow settings....
Another suggestion, if you haven't already done it, is to weigh each of your outer wing panels on a sensative scale, and note the difference in weight. Affix 1/2 of the weight difference to the lighter wing in the aileron servo pocket. This should allow you to remove any aileron trim at the transmitter.
Practice slow flight with everything down and dirty, until you can't stand it any more, then practice some more. Try flying a few tanks of fuel in just slow flight, and landing pattern practice. Can't hurt ya none.
Hope this helps......
