ODR Designs

I had a "Lean Green Racing Machine". One of Chris Greengrass's designs. Like a Nova but about twice as big!

That developed into the "Sigma" MkI and MkII that we brought to the ISR in 1986. Wicked models.

Blimey Brits: L-R: Jim Hathaway, Me, Mark Passigham, David Woods, & Chris Greengrass.

Magical times.

Doc.

Still hoping for a pic or two of the Sigma. I have some at my moms house, trying to see if I can get her to dig them out. I can still see the schemes in my head, that was the team to beat!

Red if you do find some, please post them, or send them to me. I dont have any either. I made the fuselage plugs and all the fuselages.:cool:

Cheers,

Kudos to Mark for 3rd place!
I'm surprised Mark made the flights at all with the amounts of beer we were drinking, but he was, and still is a really good flyer. I think Mark flies like he fishes for big carp: Spends a lot of time seeing whats going on, then not too much time hitting the target.

I crapped out in the very first round with literally no wind and a beach landing. Then I had to repair the model so no more flying that day. Second day was better and I eventually caught up a bit and came 13th (out of about 48 as I remember)

Chris had a mid air and lost half a wing, but still landed OK that day - like me pretty much out of the competition but he still got the design prize.

Joe Wurtz won with a model that was clearly outperformed by our Sigmas, but Joe is such a damn good pilot that he would probably have won with a Gentle Lady. Ron Vann was second with the first all-moulded model that I had ever seen (It was gorgeous). Ron has probably won the ISR more times than anyone and certainly had more podium positions.

I sold all my fuselages though - I took 12 so I came away with bulging pockets but no trophy. Sold my model too, come to think of it.

Here’s a link to a 2009 RC Soaring Digest with a story about the Bad Voodoo ODR that starts on page 49.
A year or two later Erik made the Bad Voodoo Pro with a longer nose to get the nose weight forward more and a different planform.
A pic of my Bad Voodoo Pro after some re-done accent covering and a fuse repair. With a little luck it will soon be retired as my back-up.

I know someone who could make really nice glass fuselages, really fast and really cheap.
Perhaps you could get the molds/desgin from Erik for his Voodoo Pro fuselage and see how much it would be to make a run of them.
Wing cores for ODRs are pretty simple. A glass fuse makes the build a lot easier than an EPP fuse, although the EPP fuse is handy when flying Rocky Mtn slopes.

Someone could bundle a set of cores and a fuse for a basic kit, or add in a few pieces of balsa for sheeting and tails with plans for a complete kit.
Of course people could contact Larry or Erik for Cobra or Voodoo kits as well though I'm not sure what the wait might be for them to crank out a kit, especially if Erik would need to build more fuselages.

But with some glass fuses and cores cut an inch longer, people could put together any wing and tail configuration they would like to.

Here are some pics of my Cobra and my new plane which I believe has a Voodoo fuse, so I'll call it Voodoo Child. Plan A and Plan B styles.
Going with top drive servos for the new glider (not installed yet) to reduce potential linkage damage on landings and for easier pre-flight checks.

The new wing should be faster (Orange is well established as being faster than other colors). Covering material is Aloft's flying film which was easy to use and looks nice, which is likely why that color is sold out. But I made the tail surfaces squarish to make the plane look slower.

Pics of the Voodoo Child ready for a test flight. Top drive flaperons. 26oz with ballast tubes installed and extra nose weight for first flight. Hope we get a good turnout and nice winds for the Wings Over Wilson event in KS next May.

I have decided to move forward with this project. I'd love to see some MoM racing locally again, so this might be an inexpensive way to promote it. The fuselage plug is printed, just needs a little bit of minor filling and then paint and polish. I do intend to make kits available.

Sweet = Love the fuselage styling. Sort of X-ray like. Wing fillet looks well thought out, but might be a pain in the butt to layup.

That's a situation where you fill them up with splooge before the cloth goes in lol
 
Sorry for the newb question but how does MoM racing go down? Laps, transponders?
Hey Jake. Pylon Race 101:
  • Course is 2 pylons with the course length dictated by the contest site. At Davenport for example its pretty long.
  • Up to 4 contestants in a race.
  • To begin a race, the racers first fly in a designated space off course, circling until the CD sounds the horn, then all 4 dive for the start line. Positioning at the start can be critical.
  • Each racer has his own designated flagger - or if available an electronic beeper with lights to call the turn passes. Pass the turn and the light goes on.
  • From there is all pure bred unrefined excitement as they race up and down the course for 10 laps.
  • Cut a turn and you have to go back - if you are close you can loop.
  • Its a good idea to have a caller by your side to help you to gauge when to make the turns.
  • The race runs though heats with the race winners going to quarter finals, semis, and the grand final.
Mid air collisions are not uncommon, and yet not as common as you might think. I'm sure if you looked at the model carnage at the end of an F3f comp where the pilots are flying solo, it wouldn't be too different from a 4-up MOM competition. I can tell you which is the most exciting and fun though. Bang for the buck? Nothing beats MOM.

Cheers,

Doc.
