RE: 60 Size
you might want to try to get your hands on a Fliton Infinity or Surpass 90. They were really great, and light!!! Still don't understand why Fliton discontinued it....[

Tommy,
Yeah, I've looked at the Tajeiro's before. The 90 size is heavy and the 50 size too small. It's hard to find a true 60 size anymore. seems like it's either 40-50 size or they jump up to 90 size and over 8 lbs. Looking for something around 750 sq inches and 7-7.5 lbs.

I must assume the 90 will be very close to a 140, and that is a great flying airplane.

RE: 60 Size
They report a weight of 3,5 - 3,7 kgs, so that is about 7,5 lbs. However, I am thinking about installing an OS 120AX iso the FX91. Any thoughts on this? With an 120AX or YS-110, you should have adequate power, even if it would get close to 8 lbs.

I would consider a Tojeiro if I thought you could keep it under 7.5 lbs. My point in this thread was to find what's available as true 60 size pattern planes. I have a saito 100 which really can't pull more than 7.5 lbs in the upper classes.

Jeff, I thought the Surpass-90 was no longer available, but here it is again. I flew this plane as a Fliton Infinity with an OS-91FX, but it is actually designed for a 4-stroke. Your Saito FA-100 will be perfect for it!!! The OS with header and pipe is 890 grams, so heavier then your Saito, and with this, the plane was less then 3,5kgs (<7 lbs).
I would absolutely recommend this airplane, just strenghten the wooden engine mount and the landing gear plate before your first flight.

Flew the Inspire 60 last week and it flew like I expected. I set it up for pattern and it was reasonably smooth. Mine was a bit nose heavy even with elevator and rudder servos (JR9411 std not the sa) in the tail, so knife edge flight was not good--extreme pitch to canopy due to the up elevator trim. I've replaced the 4 oz battery pack with a regulated LiPo at half the weight up front, behind the firewall so that corrects the cg.
In addition, they built so much right thrust (around 4 degrees) that the model also had extreme proverse roll couple with top right rudder (rolled to the right) while left knife edge didn't show any roll coupling. Removing half of the right thrust will cure most of that.
Decent vertical down and up lines. Lightning fast roll rate even at low rate, so it's great for 3D. Sluggish in pitch even at 30 degrees of throw due to the fore cg and the larger than necessary hor stabilizer area (stab-elevator area). I reduced that by cutting the elevator down about 30 sq inches.
(I know that elevator area reduction to cure a sluggish pitch command sounds counterintuitive, but its the easiest way to reduce hor stab area which will make the model more pitch responsive, particularly when snapping. Large stabs belong on trainers not on aerobats)
Rudder response and damping are very good. Nothing to change here. BUT, snaps, as I alluded to above, are nonexistent due to the fore cg, the very large stab area and the baloon shaped LE on the wing. I added stall strips to the wing LE at the tips to cure that shortcoming. Not too much, about 9" length of 1/8"x1/2" balsa strip, glued on edge to the LE at the tip.
All simple changes. Overall impression of the model was positive...built decently and very light. Mine came out at 5 pounds but I replaced the stock landing gear by building a set from a balsa and carbon composite. If anyone is interested, I can detail it in a different thread. It's simple. The weight savings is around 50% on the RTF gear set. For example, how does reducing the strut weight from the stock 70 grams to around 15 grams sound? Also chucked the stock push rods and built a new set from 1/8" carbon tube. The whole set of push rods weighed less than 1 stock steel rod, 11 grams vs 13 grams.
