Unionville Dehavilland Beaver - 8' Turbo

Hello Everyone,
I have ~5 years of flying experience, stick built the trainer I learned on, and a profile plane but aside for those I don't have much stick build experience.

The winter if fast approaching, and there is nothing taking up the building table. The problem is I have a Saito 100 that is sitting alone on the shelf with no airplane to keep it warm. So I've decided on the Unionville 8' Turbo Beaver as the next project. http://www.greathobbies.com/producti...rod_id=UVH010T

I have wanted a stable big plane for a more relaxed flying experience, plus I love the look of this airplane. So as an inexperienced builder I have some questions:

1. Is the Saito 100 going to fly this plane well? Its spec'd out for right in the middle of the range, but realistically will the plane hit those?
2. I haven't found very much information on this airplane with respect to build logs or setup tips. So i'm looking for setup tips? Can I use standard servos? Do I have to go high torque for ailerons or rudder?
3. I'm concerned that the manual will leave 'too' much to the imagination. I can build but with little experience there is probably going to be a better way to do it.
4. Although, I am pretty well stuck on this airplane does anyone have a better stick built kit airplane that would fit this engine and has about the same flying characteristics, but better instructions and support?

Thanks!

Mark

Hi mark going buy the specifications listed the 100 should be fine in regard to servos good quality 4-5 Kg servos should be fine for all major surfaces. A buddy of mine uses the rule for a scale model to use half the final weight of the model as the minimum torque however if you fancy getting a little more technical jump on the us large model website for a flying surface calculator this will give you an accurate figure.

The Saito will fly it fine, I've got a OS 91 fs in mine and fly it at less than 1/2 throttle most the time. and I sheeted and glassed mine. If you've never built a kit plane before you might find this kit to be a challenge although I'm not saying it can't be done. The instructions are good but still leave a lot to the builder. I'm not trying to put you off on building this plane. It builds into a very beautiful and enjoyable to fly aircraft.

Thank you both for your reply.

I'm still going to get the kit, and will plan to use a standard servo HS-485HD - 5kg/cm servo with the control surfaces on this plane. I am looking for a challenge and think I'll be able to find answers if they arise.

Herman_Munster - do you have pictures of your finished Turbo Beaver?

Mine is the radial version Beaver, basically the same though except for the cowl

Standard servos are fine, I used modern mini servos to save weight, I believe I have them listed in my build thread - http://www.wattflyer.com/forums/showthread.php?t=52062
and one I follow on RCC: http://www.rccanada.ca/rccforum/showthread.php?t=84030

and one other I've used as reference on RCU: http://www.rcuniverse.com/forum/m_1304564/tm.htm

I've seen it mentioned elsewhere, but those are the ones I have bookmarked - btw, the Canadians are very helpful and many people have built the kit if you ask questions on RCC.

I've read several threads where the kit as been built to plans - and they fly great. A few places are vague, but just ask on the build threads if you have questions!

The unionville kit really impressed me with the balsa quality and the finished product, if you want a little more 'mainstream', I can think of the following:
There is a 20CC trainer off the top of my head:
remember glow produces more power at less weight than gas, so several planes on this page: http://www.amr-rc.com/index.php?path...=AMR&page=kits
there are a few others out there, but I always remember that one.

Is the Saito 100 enough for the MRAero kit? I thought it came in close to 20#s, and usually had more like a 32cc plus gasser in it. It's a pretty amazing and scale kit, but it sure takes things up a notch or so.

The MR Aerodesign kit is a great kit, VERY close to scale and easy to build (mostly interlocking parts)- but it is heavy and requires a 36-45cc gas or equivalent power plant as maxadventure mentioned. Also if you are not in North America the shipping is very expensive. When I was looking for a large Beaver I too checked out the Unionville kit, but for realism it would be hard to beat the MR kit.

Good luck with your choice
