Ken,

Looking good. Can't wait to hear how she flies.

I like the idea of covering one with fibreglass. Being so large she should take the extra weight well.

Dear Ken, I am pretty sure that you will be happy with Formosa-II.

GWS RD Steve Lo had flown so many times of Formosa, but he loves F-II way much more than her little sister.

Hope you will have time to try it and post your comments here ASAP.

My mixing set up is:-

1 Flaperon 100%
2 Flaps 50% on both positive and negative using the Flap Knob
3 Flap elevator mixing is inactive because my switch is broken and I need to buy a new one.
4 Landing/Airbrake 35% down flap and 10% elevator compensation
5 Ailerons 70% ATV 40% Expotential
6 Ailerons Dual rates 100% and 70%
7 Elevators 1005% ATV 40% Expotential
8 Elevators Dual rates 100% and 70%
9 Rudder 100% ATV

So everything is ready for first flight tomorrow morning. Sorry that there are no radio instalation photos but I am just too tired to take them. I will do so tomorrow morning.

The ready to fly weight is 686 gms (24.5 oz)

For a number of reasons, the most significant being the birth of my fourth Great Grandaugher this week and subsequent family celebrations, I have not been able to test fly yet.

But the extra time has allowed me to fit the undercarriage. Most of my flying will be without the wheels but the mounts will fill the big holes in the wing. I epoyied the ply plates into the wing and then placed a 3/4 oz fiberglass patch over them to stengthen the mount. A 2 mm carbon fiber rod is epoxied under the tail to provide a tail skid. I have since added a small length of wire on the tip to prevent wear on tarmack and concrete runways.

Ken,
It looks like the servo arm would be exposed to catching on grass clumps, etc. in belly landings and possibly damage the servo gears. I assume there is nothing included in the kit to help protect against this (e.g. a small plastic bubble or shield of some sort) since it comes with landing gear (I think).

Maybe this is not as big a deal as it looks in the picture. Your opinion?

Also, are the tail feather pushrods designed to both come out the same side of the fuse as shown in the pic with the tail skid, or is this your mod? Looks like they might rub or snag on each other. Again, I may be misinterpreting what the pics show.

If the undercarriage is fitted then it will prevent the servo being damaged. I will be fitting short wire wiskers coming out of the U/C mount. I had thought about this problem but with the things that have happened this week it had slipped my mind so thank you for reminding me.

I've mod'ed my Formosa1 with dual aileron servos pretty much like these. I've handlaunched/bellylanded mine over 50 time with no damage to the servos.

How about the tail feather pushrods being on the same side of the fuse?

Ray my problem at the moment is that sunrise is at 6:30 AM and the wind starts at 7:30 AM so I only have a small time in each day in which conditions are ideal for test flying.

When we tested it. It was very windy.
