RE: Turbinator-E
I finished mine a couple of days a go. This particular plane is not an easy build. The effort was worth it. I did deviate from the plans a bit.
I am a bit lazy, and so I ordered the short Kit From Laser Design Services. All the parts were very accurate. Shipping was reasonably quick and well packed.
I don't like the idea of the aileron servos on the bottom. I have this issue with electronics and dirt. They were moved to the top. It is something I have done on other planes, and noticed no difference in the way they fly. I happened to have EPF retracts. Installing them was a bit of a trick, but with a little ingenuity and some careful surgery they fit fine. I didn't care for the canopy shown on the plans. After roughing out the fuselage, it seemed that it would look tacky. This fuse has such elegant lines that I elected not to install the canopy shown. I used some trim Ultracote and got creative.
The hatch as shown would not have worked for the setup I use. I prefer to build planes to suit the batteries I have. My current favorite is Zippy 1450 3s 30-40c. These will power everything I fly from a GWS Slow Stick to a Stryker with a WM 400 fan drawing 49 amps. I have paralleled these with great success. With this in mind I set up my Turbinator using two of these batteries in parallel. The fan I mounted is a HET 6904 with a 2W motor. On my test stand this combination provided 42 ounces of thrust at 52 amps and around 490 watts. The hatch has been extended one former further forward. (Starts of F-2)
CG as marked on the plans came out with the plane balancing slightly nose heavy when the landing gear is in the up position. Weight came out at 49 ounces. I haven't had the chance to get a maiden flight on it. It strated raining here a week ago, and as usual it is still raining. I tried to post the pictures of the finished bird, but was unsuccessful. If I do rekit this one, I will have to build another. It is a very elegant plane that was well worth the effort to build.
