Multi Motor Micro Build


The contest is now closed for new entries.

I was given permission by the site administration to have a building contest. There will be prizes, and RCG is donating a one year Plus Membership to be given away.

The point of this contest is to get some building activity on this forum. Contest will run from Sept. 1 until December 15, 2013. Winners will be judged by a poll of RCG members.

There will be two categories: Scale and "Anything Goes"

Here are the rules:

1) The model must have a minimum of two motors.

2) Model must be fixed wing. No copters or multi rotor craft.

3) Ready to fly weight under 50 grams.

4) Any brushed or brushless power system is acceptable.

5) Original projects only. No recycling something you have in storage.

6) Builder must open and write a build-log thread. Plans/drawings are to be included in the thread. A proof of flight video must be posted within the thread.

7) Start date by October 15. Any entries must have begun a build log by this date.

(Rules subject to editing if needed)

To enter, post in this thread with a short description of your project. Your name/project will be entered in the second post.

Rules are clear but by which criteria will the winner be chosen?

If it's not going to be a scale contest I think it would be useful to have some sort of goal, like "must be able to lift a payload of a least 33% of AUW", or must have flaps and/or retractible landing gear, nothing outlandish but at least something to push us past the most obvious designs.

I think that the max. weight should be bumped up to 70-80 grams. This would make it easier to put more scale details, like flaps, retracts and bomb drops. It would also allow people to use guts from the parkzone micro mosquito, which weighs about 70 grams.
Just my $0.02

Hi, guys.

My computer's been down for two days. Just reformatted, and it's working great.

Pouncer, there will be a poll to chose the winner, as stated in the first post.

I would prefer a scale contest instead of a payload contest. However, I am open to suggestions. The idea is to get maximum participation.

I have to go out. I'll be back in a couple of hours.

If you want maximum participation, leave the contest with the basic rules first stated.

Scale is great but it would also be great to see original multi-motor designs designs.

I agree - keep it simple. It's enough of a challenge to get participation.

is there any chance of raising the weight limit to 70 grams? 50 grams seems a bit light to me.

there are probably lots of people out there with a busted up parkzone mossie or a flyzone p-38. both of those planes weigh about 70 grams. being able to use the guts from them would bring more people to the contest, and enable more working features, like retracts and bomb drops.

Addictedtoplanes,I got the point the FIRST time.

Who expects anyone to include these features at 50 grams? I don't.

Having a weight limit has a couple of points:
1) Emphasize micro. This is one of the issues with recent posts in this forum. There are often projects that have merit, but are outside of what many consider micro.
2) By having a weight limit, the build becomes more of a balancing act. If the wingspan is over about 500mm the aiframe makes it hard to make the weight. If the winspan drops much below 500mm, the wing area becomes too small to make a nice flying model. IMHO, this makes an interesting dilemma.
