Default Airsail Beaver

Thinking fo the Airsail De Havilland Beaver (61" span) for a winter project. Anyone built or flown this. I have a OS .25fx just sitting on the shelf. Would this be just about right for power? Your opinion on this kit appreciated.

do you have a link to this kit? also it seems like at least a 40 size 2 stroke would be in order for a plane this size.[&:]

I'm currently building the Airsail Beaver.

Great kit with excellent hardware and balsa quality.

Having said that, the supplied engine mount is too small for my engine of choice, so got to substitute that.

The ABS Components are very thick so will stand up to punishment, though cutting them to final shape will probably need some Dremel router use.

I'm going to power mine with a Magnum .32 fitted with a Pitts Muffler.

The instructions advise that a 4 stroke fitment is possible, but would need some cutting through the firewall to set the longer 4 stroke engine back further, to allow it to correctly fit inside the short cowl.

Although it cries out for a 4 stroke, I decided the mods were just to bothersome for me and having a .32 2 stroke lying around in the engine drawer........ Well---- it got the nod.

I am going to fit a GWS mini servo in each wing for aileron control rather than the bellcrank
arrangement that the kit manufacturer provides.

All in all, its not a difficult kit by any means. My Flair Harvard (AT6) was harder to build.

I can't comment on the Tomahawk, but if its quality is anything like the Beaver, it should be a nice kit.

I built one and flew it with 2 different engines. First was an OS 48 Surpass. Sounded nice but was way to heavy. The supplied undercart is extremly stiff and anything but the gentleist of landings would rip the legs clean out. Extra reinforcing is needed in this area or a softer undercart. Secound engine was a OS25 FX. Flew a lot better and at the recommended throws, would still have more than enough elevator for landings. Used 2 mini's on ail., mini thr., standard rud and ele. Had bought the kit for my Son to build but the instructions left a lot to be desired. As far as I know this was one of their earlier kits and these minor problems may of been corrected by now. Nice flyer, now sitting in the shed. Not my thing.

Fles the Beaver off grass. The 25 was more than enough power. It is only a gentle flyer like a Cub.

I just got an old Airsail beaver kit.  There are plans but no instruction manual.  Any one know a link to where the instruction manual is posted online?
