20cc Pattern Plane for Practice

    OK. I know this may be heresy, but I have a VVRC 20cc that needs a home. Have everything to build a MOJO 65, but really thinking about a nice practice plane to work on sequences without pulling out my bigger planes. I have a .40 size Utter Chaos that really flies well, but would like a gas version. It is surprising how well these pattern planes handle the wind and fly.

    So.... I have started looking at old pattern plane plans to scratch out something for the 20cc. From you guys that have flown these, what do you recommend? I was looking at the Kaos 90 plans that are 25% scaled up from the 60 Kaos. It is a 73.5" wingspan. Or the Reaction (mid wing) with a 70" wingspan? Am I way off, or in the ball park?

    Any thoughts? Thanks!!

    Page 2 has the reaction. Page 4 has the 90 Kaos.

    If you build the mojo be careful with your wood selection. One guy I fly with has one that is close to 9lbs and another guy built one for his club president that was around 7-1/2lbs. At 9lbs a DLE 20 is really lacking for vertical and get out of trouble power.

    alright, alright!! Mojo it is. Still interesterd in scratching out a pattern plane though.
    Thanks Chris on the heads up on the wood. Will pay close attention. I suppose a build thread would be in order?

    Is that the Primo60? Looks like you had to add a lot of lead to the nose. Will be mindful of that and maybe move the tail servos up a bay...

    image.jpeg Yes that looks like a primo in his picture. Here is my mojo40 (L4 look a like) and I should be picking up a Moass60 at Nash next week.

    Very very nice! The moass is a longer fuse, yes?

    No the Moass stands for More Ass. Basically its a stock mojo 60 with bigger elevator and rudder.
