Need in-put on the Sig Riser
 

I'm thinking of building the Sig Riser 100 this winter, can anyone give me in-put on construction, and flying of this plane? Should I go to some other glider? Thanks

captjckirk- If it's anything like the Riser 2M, it will be a winner. Last year I built a 2M Riser and it was an excellent kit and an outstanding flyer, and I understand the Riser 100 is ever better. The only thing I could suggest, if it's not on the plans, would be to glass the dihedral and polyhedral joints. I used 4in. nylon and epoxy on the dihedral, 2in. on the outer poly joints. Good luck- Jim

Build it. You'll like it. My Riser 100 is my first built up plane and it was a relatively easy build for me despite the modifications I added which included:

spoilers: you'll need them to get down from boomers. I used wing mounted servos

move battery and servos as far forward as you can: there's plenty of space

add carbon to spars with full thickness webs on main panels and wrap with Kevlar thread: I wanted durability for winch launching and so far, so good

add glass to the fuse from just aft of the TE forward and glass on the main panel sheeting

bolt-on wings

move-able tow hook with ballast box on tow plate

Because I am a new pilot and learning to land on target, I discovered a weak point you may or may not want to reinforce. Seems that my hard landings fracture the fuse just aft of the TE. Part of this may be due to the taped-on landing skeg in addition to bringing it down too hard/fast. Anyway, some reinforcing plywood and/or glass at this point might be worth it.

And, plastic push rods really bend a lot when it gets hot. I'm always trimming to compensate. I'd consider balsa push rods or carbon fiber.

Despite all of this kit bashing, the all up weight is 49 ounces. It flies well, even for a beginner like me. It's a good plane. I'm glad I built it. My flying coach still flies the one he made when he was a teenager.

Thanks guys for your response, I really appreciate it. Looks like I'll be cleaning off the bench and getting a new bottle of CA. Thanks again.

I have one I built last year(Sig Riser 100). It is a good thermaler. The only thing I can compare with is my 2 meter Spirit. Flight is comparable. The Riser is a little slower on the rudder. The Riser is better on duration or thermaling.

My Riser 2m is one of my favorites and the 100 is my next building project. The fuse on the 2m has been recovered three time and the wing once. It has many hours of flight time and numerious hour + flights. I fully expect the 100 to be even more enjoyable. The plans look like it will be a fairly quick build once I get it on the board. I will be using the spoilers.
