With the FAA's looming guidelines, sub 250g builds will become hot. Love it or hate it, they are something we will probably all need to get good at, so why not a little practice? The goal of this challenge will be to build as light as possible while still maintaining adequate flight time, and look cool while doing it! With that being said, here are the rules:
Sub 250g Challenge rules:
1. It should be made using some foam. Other building materials are allowed, but we are Underground Foamies after all! If you choose to 3D print, it should be of your own design.
2. Weight In- Must be done using flight battery on video -1 point for every 5g over 250g, + 1 point for every 5g under 250g. We are trying to allow for a variety of scales.
3. Flight Time - We start with 4 minutes, and every 15 seconds over 4 minutes, we add a point. So for instance a 10 minute flight time would be +24 points. Plane must remain under powered flight the whole time. No gliding around and trying to catch thermals or slope breezes. You can run your plane to voltage cut and land dead stick if that is your wish, and that would be the only exception.
4. Cool points - Subjectively awarded by the judges, up to 10 points.
5. Signing up and failing to complete the challenge results in your avatar being turned to a rubber chicken for a week, no ifs, ands or bocks about it.
Timeline:
Sign up due by June 1- We don't want someone coming in the last few days and trying to rush into the contest, it isn't fair for the contestants.
Final videos and design due by 15 July for judging.
There will be more than 1 judge, just to keep it objective. If you don't want to compete, volunteer to be a judge! Message the admin or a mod if you want to be a judge.
Prizes-
First place is a $75 Amazon gift card.
Second place is a $50 Amazon gift card.
Third place is a $25 Amazon gift card.
Hope to see some neat planes.

Well, I guess I'm onboard. I'll probably edit this post multiple times to add content, so i don't have multiple posts taking up space. Going to unarchive one of my classic designs for this one, I suppose. Despite the lackluster name, The nano striker has made waves everywhere I've taken it. Weighing in at 11.4g rtf, there's not really much to it. xD It's one of a series of five wings built between 2014-2015. the largest having a 5 foot span, and over an hour of cruise time. Anyfoot. Photos, for now. Other media will pop up as the weather clears again. I haven't had it in the air this year. It will be good to get it out in the open again. EDIT: Righto. for the sake of confirmation, Realtime weigh-in, with scale calibration cycle included. streamable.com/isuo7fEDIT2: First post-un-archival flight of the year.  Just under 5 minutes. I will post another after i can buy a few more new cells. It's so old that it's running at under half capacity. Fun fact, there's zero stabilization onboard. Primarily because I'm against that sort of thing. Also, it didn't exist in 2014. It's also unnecessary due to the inherent stability of the design, even in moderately high winds. streamable.com/3bbhb5 |

I see what you mean by your design has been used for "inspiration" by others. I am not competing, but i built a plane for funsies anyway just to see how it stacks up. This is the prototype (therfore the random hacks and tape everywhere), I'll have plans available when it gets finalized. Will easily be sub 250, have a 1000mah 2s, and should have some good flight time and aerobatics to it, as well as be able to deal with the wind. A plane with this set up and the aerodynamics of a barndoor was able to fly 8-10 minutes on a 300mah 2S. Should take a little over a half sheet of foam board. It is a design I had been mulling about for a while, just never got around to pursuing it until my nanoflerkin ended up being a dud.  2022-05-12_09-36-07 by Burkeomatic, on Flickr |

I will be participating, but will not be a contestant. Good luck with the builds my friends.

I think if I could enter my ZOHD drift I would smoke everyone. If you want inspiration, copy that set up.

That raven looks so cool. I have some 30mm edfs on the way here from  Might be cool to make an EDF bird. After going to the beach, I kind of got to where I would like a pelican or a seagull. I was chasing, (and getting lost by) a Cara Cara yesterday. |

Just have to finish sanding the leading edges and hit the wood parts and motor with some black paint. Should look really nice with a coat of clear on it. Fun little project and I am guessing it will go pretty good too with the 2212 1400kv and the 8x6 prop. I think this scaled up to 200 % would be a fun bird as well. www.amazon.ca/photos/share/dFocJkK389hBzW1ZE9ORtpMHo8PRyTT9bqzv1R2b3QQ |

Build #2 for the challenge almost complete, This is the Telemaster, I take no credit for this design, it is basically the original design by fellow member here OliverW. I built this one already and it was a blast and still commands a spot on one of my racks, this time around I went with a different wing type and added ailerons, and permanently attached the wing instead of it being removable. Still 3 channel , no rudder just ailerons and elevator. It has a 30 inch wingspan and is 26.5 inches long and currently weighs in at 90 grams , in the end I think it will finish up with an AUW closer to 200 than 250. Just about to set the ailerons in place and then call it a night. www.amazon.ca/photos/share/ZX3cTRU0dQ0s8Ma4arCjxA0wHMA17AhHl9OsJqwj2zb |
