Default Test Flight....wow!

I test flew a H9 Taylorcraft today with a Saito 180 for a friend. It was amazing. It is one of the better ARF's I have ever flown. I was doing sustained knife edge passes and sloooooooooowwwww rolls on the very first flight and the motor was still set very rich. I was also suprised how easy it was to land with the very first and second landings being perfect. The plane had zero bad tendencies and was very aerobatic. I can't wait, they want me to fly it again in two days. I'll take some pic's and post them.

Since nobody here is answering your post i thought i would at least make you feel good the report is great i am putting one together now with a YS 140l i think this will be a good combo since the power of the 140 equals the 180 i am excited to hear about your feelings of the plane it sure is a beautiful bird Bruce By the way i am using two servos for elevators hitec 625s in the middlle of fuse on Sullivan black and gold nyrods and i am putting rudder 605 servo in the rear fuse will need some weight up front i know to balance but this set up is easy and quick. Using 615s for ailerons

Hi Bruce. My last post was deleted. I wonder why. Maybe I said something and a shmoderator didn't like it.

I've got some advise from an experience flying it today. Throw away the screws and blind nuts for mounting the motor mount and get some decent ones. The blind nuts that came in the kit were soft and stripped. I must have overtightened them. I also used locktite. The motor came lose and died on me. The blind nuts were all stripped out. I'm going to replace them with 10-24 screws. The prop is balanced and I really don't think I overtightened them that much if at all.

On the third flight, which was the one where the motor came lose, I was flying knife edge and it was able to pull into a hover by feeding in some more rudder. As I was hovering one of the wheels and pants fell off. It turns out a guy at the LHS assembled the landing gear for him. I should have checked it before flying it. I was able to land on one wheel and stopped the plane completely before the other side touched dow. It is a neat flying plane.

Here is a pick of the plane with the motor and cowling off.

Here is the radio layout. Rudder is a 605, elevators have 300's, throttle is a 3003. Heavy duty servo arms all around. Plenty of room.

The pushrods are the Dave Brown fiberglass ones. I am using a Dubro 4-40 threaded end extension and Sullivan clevises. I've seen too many planes go in due to balsa pushrods breaking.

They are heavier, but to me they are worth it. I weighed a 3/8 inch balsa dowel and the DB fiberglass pushrod material (about .3 inches). The fiberglass rod is about 35% heavier. That 35% increase in weight more than makes up for itself in strength and durability. I have researched arrow shafts and the local archery shops only sell them in large quantities and I don't feel like spending that much money at once for pushrods. Maybe there are other shops that sell them seperately. I just don't have the time. The LHS stocks them and I live 3 miles away. They are around $6 for a pair of 36 inch pushrods and the end fittings.
