I had to shorten mine (just made it short enough to clear the elevators at all deflection combinations of the rudder and elevators) and I too used a 3" offset arm with the h9 control horns and straight (not crossed) lines.

I put mine in as far in as it would go. Then just made sure the rudder horns didnt hit the elevator using the end point adjustment.

thanks guys, i think i have it so it doesnt hit the elevator. whats the reasoning for a crossed or uncrossed pull-pull rudder wires?
Im just waiting for a control horn to come in, bought the lhs out of there stock and they didnt have enough. that and my rx and an ignition switch from Emcotec. I am still concerned about my tail being heavy but we will wait and see where it ends up..

No just the yak...and my pride

Lebowski,
The reason you cross the wires is to keep it from contacting the edges of the holes. It just depends on the size of the rudder horn and the width of the fuse where the wire will exit.

thanks guys,all i have left is the ignition switch and battery placement rx came in today.

i did the maiden flight of my yak today, really windy out so it was not easy to fly but did a short flight and i landed it safely. i ended up with 12 oz of lead on the engine box. all my batts are on the engine box as well.

Congrats on the maiden! I got mine on charge for tomorrow, post some pics when you get a chance.

im going to giant scale event tomorrow so will do.

honestly wish i could get my DA 50 runnin right.I sent it into service and they replaced the crankshaft bearings only. they sent it back with the service report saying they test ran it up to something like 6800 rpm. now i got it on the airframe and i cant get it anywhere past 4500 rpm. WTF? need to hire a personal engine tuner,would be great if she cooked and cleaned as well......

Are you sure the ignition isn't plugged in backwards? Where the sensor plugs into the ignition box, it will run if you have it backwards but will not rev past about 4500.

I test my engine in my hard manīs Yak today and I hopes to fly low next week

Is nice to be me the crazy Sweed today
