    H9 Beast Winter Maintenance

    I bought this Beast last winter and flew it last season. The previous owner had it set up for sport flying so I already installed longer servo arms and moved the batteries under the turtle deck. It flies well.

    I wanted to do a couple of small maintenance things this winter. I wanted to clean/rebuild the carb, clean the cans internally, install the new Spektrum 9140T failsafe receiver, RPM and engine temp telemetry and install an IBEC. I already changed the plugs and installed a new ignition in the fall.

    The carb is rebuilt. I used Super Clean to clean the cans internally and a ton of crap came out. I didn't take any photos or make a video but JoeT already has a great video on this process.

    I noticed that one of the cans had a crack at the stinger. I took it to my friends shop and he had one of his guys weld it. They also did a reinforcing weld on the other can in the same area and polished both cans. They look great!

    I will get the engine and exhaust reinstalled and test/tune the engine this weekend. Had enough of the cold...COME ON SPRING!!!!

    Thanks man! I still feel like the plane is a touch nose heavy. I'll fly it this season the way it is and see how it goes but I may consider removing the cans and going with nasty stock mufflers. To be honest, I would have done that already if it wasn't for the Burlington seniors LOL!

    Re: H9 Beast Winter Maintenance

    I run all my batteries on a plate in the turtledeck, light 2200 lipos. With canisters. It works well, I went to tuned pipes and it seemed to work almost too tail heavy from a balance stand point. They are very forgiving for cof I had a dle111 on one with stock mufflers with a pound in the tail, flew wild it was awesome and nasty sounding.... . The more neutral cof is still plenty hot for an old fella like me

    I hear ya Hanes! I'm not complaining...it flies well. Just being really picky here!! I love the way the Beast looks in the air...especially on a sunny day when the colours really pop.

    Ancient Chinese secret....


    Just kidding Ed. The previous owner had it setup for smoke which I think is cool (especially on a biplane) but I ripped that stuff out. He had the batteries around mid-fuse and I made up a plate and put them under the turtle deck. It still wasn't where I wanted it to be so I stuck some weight near and on the tailwheel bracket while at the field one day. Way better now.

    I hate adding lead weight to a plane but not practical to go further back with the batteries. If I went with nasty stock mufflers, I would be able to remove the lead from the tail and it would probably be perfect.
