If looking for 3D in the 60-90 size, have you considered OMP RazorYak or Aeroworks Prox260 profile that was just released? Aeroworks is $50 cheaper than OMP.
Aeroworks planes always come out SO HEAVY that I'm not sure if it's worth it. The Mojo 60 has more wing area and it's rated 1.5lbs lighter....and Mojo's come out on par for weight where as you have to FIGHT to get Aeroworks planes to come out at their advertised weight. Money says that the Mojo 60 will weigh 5.5 while the AW PROX260 will weigh 7-7.5 lbs. In fact, their full-fuse Extra 260 and Yak 54 come out to 7.5lbs.

Also, your Saito 100 will simply NOT fly the Yak90 well. It may be able to handle the Yak60, but with similar performance to the way your Edge flew.

First thanks for the info, second my Siato 100 was purchased used with the extra and has never produced long flights. It had a 15x6 prop, and I will have to check the tank size. In the end though a 6min flight was pushing it. In its last flight the engine died on take off after a nice warm up and was running just fine on the ground. This is on a plane that had been flown a bit with no issue. I may try to bench test the engine, but also want to try gas.

Thanks for pointing out the weight difference and I will have to check how much nose weight is on the plane I have I believe it is a bit, but doubt its enough to double the engine weight.

What size are the new gas engines coming out?
Here is a link to more information on the new little Magnum .52 gas engines. Just file down to the Magnum video interview.
