I have a half built Riser that I am going to convert to e-power per conversion article in Feb 2001 S&E Modeler. The article mentioned watching out for heavy tail wood and sticky push rods. You may want to eliminate the overhanging rudder.

Excellent kit! Do a search for "riser 100". There is several builds going on right now in the forums. I have built two of them and still fly my second one. It is over 14 years old now and still flies great.

Here is the one I built about three years ago:

Great plane to convert to e-powered. I had to add about 1/5 ozs to the tail to get the CG right. I found it to fly the best with the CG at the rear most recommended position.

Do reinforce behind the TE, do the mod to the rudder and take a chair when you fly, you will be in the air for a while.

We can debate the rudder for eons,back in the day that the risers were drawn up,with the air foil used it was thought that the balanced rudder had more advantage because the balance area above and in front of the hinge line would help give more rudder effect in turns with elevator in put,and also give a very slight up elevator input to turns.All this aside-build as per plan,even for E power.and enjoy.If you do all sig says to do you still get a fine sailplane.For Me ill keep the counter balance on the rudder and just fly the thing.

CD, Glad to hear you bought a model of wise decision. You will enjoy the build withthe guys here. Its a great bunch to chat and dicuss the build of the Riser. Any questions are usually answered with some details. The only ones that are not talked about are the one that you don't ask. We have fun with the build and with some of us that have been building for awhile learn something new too. So join in and have some fun. Make some new friends.
Here are the threads,

rabid, CV, stargazerww and the rest of the guys that have Riers soon to be flying or flying. Gentlemen, glad to have ya here with the threads. We are planning a one day Riser fly where we all go fly the Riser on the same day. Then post a picture of the day. All are welcome. As soon as we get Bob in the air with his we will put this together.

I have the tail surfaces built on Sig Riser 100 and pushed out the ribs and fuselage parts. Some of the wing ribs are really hard balsa. Considering there is 1000 sq in. of wing should I be worried that some of the wing ribs are a little heavy?

Planning to put Go Pro in the fuselage.

When laying out the ribs for the wing I always weigh each rib and mark that number in pencil on the rib. Then I lay them out distributing the weight evenly across the span of the wing. And I always balance the wing prior to covering. I do this with every Riser and Sailplane I build. Easier to take a little wood off the heavy wing tip than add weight to the light end.
