RE: Kyosho Focke Wulf 50 size ARF Build Thread
Im going to stay with a 2 blade prop. But thanks for the info what do you guys think of the motor i put a link to. I was going to use this along with a 60A high volt castle ESC i already have and a 18.5 volt system. I dont want to peel the wings off kind of performace but do want enough for basic warbird manuvers with a tad of extra power in case i get into trouble. The motor is a rimfire .46 or 42-60-800. Thanks

RE: Kyosho Focke Wulf 50 size ARF Build Thread
I loved my Kyosho FW-190. Notice, I said loved....past tense[>:]. I flew this bird about 12 times and liked it more each flight. Here are my thoughts:
Yeah:
1. Flys almost like a trainer, very gentle takeoffs using flaps.
2. Looks amazing in the sky the the retracts up and strafing the runway at about 10' off the ground, get's lots of ooohs from the hangar crowd.
3. Looks amazing on the ground as well!
4. I trimmed for full speed and held a little elevator for slow flight, so I didn't have any climbing issues on throttle up.
5. Three position split flaps work perfect, a bit of rise when you first put them down, but if you have a computer radio you can mix in down elevator to compensate. Floats in nice and easy on landings.
Nahs:
1. the plastic mechanical retract housing suck, I could not get the set screw to hold the landing gear rod. Ended up having to re-drill/tap to larger size screw.
2. Please whatever you do get rid or don't use the aluminum tube for the control rods. I locktited my set screw in but lost my elevator on my last flight, I did a stall turn mid field and came straight down without any elevator control to pull out. The rod, screw and alum tube were not together and the servo worked perfect. I'm guessing you have about 1/2 a thread holding the screw into the control rod.[>:]
3. Has a tendency to nose over on landing, get on the elevator as soon as the main wheels touch down, or do a 3 point landing.
I'd buy another one if I cound find one.

A little tip on the aluminum control rods. After assembling put some shrink tubing over the ends and put some medium CA into the shrink tube then shrink it with your heat gun. The push rods will hold together for ever with no failure. On the retracts; there is two threaded sides to the brass bushings on the retract. Only one side comes with a grub screw. You can remove the gear leg and file an additional flat 180 degrees opposite the other flat then install an additional 3mm grub screw. A little blue loctite will hold forever too. I have all my original retracts in all my Kyosho's without replacing one unit. All my planes have hundreds of flights.

The retracts are fine for this series of birds. However, the weak part that causes the nose overs is actually the 4mm struts bending backwards on touch down or rolling on grass or rough surface. After changing them to [link=http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=5573&Product_Name=Shock_absorbing_landing_gear._4mm_(1p c)]shock absorbing landing gear[/link] the cure was found! no more nose overs (for the past 6 months)

I have been watching this thread for a while now-Question is for electric retracts witch degree retracts to use 85 or 90 degree or does someone make 74 degree ones? I have been looking at the E-Flight electric gear.
