BD-5 conversion

Well I've been flying my scratched BD-5 on a sp 400 for awhile now. Then I tired
converting it to one of the new Wemotec 300 fan's. There were claims of 8 oz. of
thrust from a single unit. That never happened but it did fly. But it could never get more
than 20 ft. up.
I was getting tired of looking at it hanging from the ceiling so I did a crazy thing. The
web page will explain it best. http://sneill.com/bd-5-r2/

Thanks Gregg, maybe the bottle nosed dolphin.
Anyway we could just test the BD and the Salamander Tues. I'm still waiting on the
CP 1300's from EAM for the Bullet. We can test that one later in the week.

Thanks Dave, Gregg and I are going to test it Tuesday. Been doing engine tests. It always flew good so we know it flies. Now if I just have enough thrust. Wants to slide across the lawn at full rpm, that's a good sign. AUW, 24 oz. Can't wait myself!

Looks good indeed Steve. You do know there was a real twin BD-5J right? Where did you put the intake when it was a single. Good luck.

Thanks Kevin. I didn't know about the twin. The intakes were just behind the canopy
about where the engines attach to the fuse.
Just found out after running the fans a few times that the rotors were working they're
way loose again. The shaft on a 300 is just not long enough. When I tried the rotor
on a 280 it was perfectly smooth, even more so when balanced. I'll be pushing a little
less thrust but it should still fly ok. As it was with 300's and 8 cells it was pushing it's
own wait across my lawn, a very good sign. I'll report back tomorrow after I run
tests with the 280's.
Steve

Hey Steve,
With the paint job and nose treatment, it reminds me of the WB-57. You could call it the RBD-5J, or WBD-5J. LOL!

Good luck, Mr. Phelps!

Steve,

You're a wild man. I'll bet you didn't think you were building a quasi-scale model, did you?

<font face="courier">Turbine Technologies Inc. did this outrageously good-looking modification to a BD-5 to install two of their TF45 geared fan turbine engines. This is their technology demonstrator. The engines only produce 40 lbs of thrust, not enough to fly, but it sure does look good. They can be reached at turbtech@discover-net.net , but they are not planning to sell their engines to the homebuilt market. The modifications were done entirely in-house. In fact, they did once ask that anyone with an interest in this type of engine for the BD-5 contact them, to gage public interest. Less than a dozen people did so, and nothing was ever done.</font>

Thanks Dan and Daren. Ya it does look like your bird from the nose. Mount some
camera's up there and you got recon.
Trying the 280's today if I can ever find the 2 mm screws for mounting the engines. I
really wish Wemotec would include those.
Hope I have enough thrust. With the 300's I was getting well over 8 oz. Before the
fans started to shake. If only the 300 shafts were longer this wouldn't happen. Can't
wait to get the updated rotors.
I'll check back later when the tests are done.
Dave got the CP 1300's in, so the Bullet will fly later on next week as well.
Thanks again guys, glad you like my Frankenstein monster!
Steve

I actually considered that, if this doesn't work, maybe I will.

Well guys I got the 280's in. Ran a test and was getting 7 oz. (on 8 600 AE's) plus
from the kitchen scale. I'm surprised really, didn't expect it. Vibration is gone due to
the longer shafts on the 280's. Ran the motors on a full battery and ran the whole
pack. No problems found. Felt like it wanted to fly out of my hands. Now Tuesday
we'll find out if she flies.
Steve
