My design engineer relayed to me the main problem, "bad motor mounts."

It seems that super glue is bad for the motors, premature failure but he assured me that new motors are arriving daily and reengineered motor mounts are in the works. Flight testing to be rescheduled soon.

What's wrong with the right engine? Looks kind of dead... Did that thing ever take off? Looks like you have too much weight for the flies... Anyone know the average air speed of a laden fly?

Found a bunch of wasps building their nest , a new source of supercharged engines for my new found hobby , ha ha ha .

Tryng to find the correct fridge temperature as these little suckers like to sting repeatedlyif provoked .

Should have the fastest home made bug plane from down under.

How can we test the speed ??

Any further advice appreciated.

What type of wasps are you using? Most species would only allow one engine per wing unless you were to trim the wings the "props" would touch and cause a disaster of proportions we can only imagine.

I'm currently raising some special flys by hand. Prototype 1 was eaten by my dog during development. My new engines are currently only in "maggot" stage and are being fed a special secret diet...

Design work is also at stage one for a special "Spruce Goose" version which uses special european matches which are required to support 4 engines on each wing.

Have had experience dealing with the suckers when my son was two years old my wife found a few wasps in the study next to my sons bedroom , she rang me at work i told her to close the door and place towel under door , so wasps could not get out.
Quickly came home by this time over 80 wasps in study, queen wasps ate through the plaster in ceiling and fell through to study her subjects followed her , holly shit over 100 angry european wasps flyng in the study .
Rang emergency pest controll group , they came out and could not believe their eyes at what they saw ove 150 wasps flying around , after doning a sealed space type suit the suckers got gassed , ha ha ha .
The next day i vaccumed the room full of dead wasps counted at least 220 of the bastards , had the insident happened at night time the consequenses could have been disastrous especially with my two year old son these guys sting repeatedly , and go into a freenzy if angered.

Heres a picture of my prototype engine (better known as a European wasp , not a local Australian type which is smaller and far less aggresive, these wasps are a real problem here in oz.)

These wasp can measure 20 mm in length width 7 mm , and can get mean they have been known to kill cats dogs wildlife in generall their sting contains a poison (toxic ) if you dont seek treatment it can attack your nervous system , and block your airways .

So before i get the insect liberalist saying how cruel , do your homework on the death these insects cause to other insects bees in particular and all wildlife in generall.

How many engines do you engineer types suggest i should place on my 1st prototype ?

Hope the super glue works ?

May do a bit of testing before i endanger myself as 3 or 4 of these wasps in an angry state can get rather nasty.

I am not a gambler but i think i will definetely beat the fly prototype engine ? , ha ha ha

A twin engine design should work for starters, but low speed flight wouldn't be a problem so a swept wing design may be appropriate.

Why not use rubber cement instead of super glue? I know you want a higher performance vehicle but the rubber motor mounts will transmit less engine vibration to the rest of the airframe.

If you put the match head at the rear and light it you will have afterburners! That should really get those engines going!

Lock & Load
12-16-2003, 01:37 PM
Guys thanks for the positive feedback , afterburners hmmmm i like that idea , having difficulty with restraining engines as subjects are not very cooperative ouch, so far destroyed about 5 engines tryng to find correct cooling down temperature .

I will be speaking to well known bee keeper for further tips on sedating the engines .

12-16-2003, 02:35 PM
...beekeepers...

along with putting them in the freezer, you could smoke them up something awful (just any kind of smoke will do... it's the CO and CO2 that keep them sedate... bee keepers use wood chips in blowers??) to keep their blood O2 levels, and thus activity levels, down.

hardly... tenths, or hundreths of a gram?? if you want REAL weight savings, use less wood, and cut of the thorax/i/es/ees/izzles of the bugs... but that would result in the rather quick death of your engines (fuel leak), as opposed to the rather slow death (run out of fuel).

am i the only one that feels badly for the insects?? i mean, this is extremely inhumane... i stopped frying ants with heat rays in the summer when i was about 10, 'cause it's freakin' gross (big stag beetles burn like crazy...)

I am concerned that these engines (wasps )get that angry that they will loose part of their leg s and sting the hell out of anyone in the area, maybe i will anchor the whole underbody less vibration .

dunno why you guys are so stuck on flies and wasps when there are much more powerful engines out there like ducks and geese...can you imagine how fast a matchstick could fly with 2 bald eagles glued together? that would be ludicrous speed

Definitely moun the body of the engines to the wings, thos motor mounts won't last long. Being in aviation myself, your original prototype, the wings were slightly to far forward for that engine design. so either go with a swept wing or move the wings farther aft.

Provided the FCF(Functional Test Flight) returns the aircraft to "Bravo" status, might I suggest the helicopter configuration. I figured mounting the engines in the center, facing opposite directions, should get you into at least a HIGE(Hover in ground effect) and if the aircraft material is pretty light, you may get it into HOGE(Hover out of ground effect), thoug I doubt there will be enough torque to sustain for any length of time. Though with this configuration, i'm not sure how you would account for yaw or roll.......

just a thought

i think queen ants would work best in your helicopter config due to their long wingspan although i'd like to return them to nature after the FCF due to their natural importance in preserving ant colonization.

The wasps are turning out to be a pain in the ass to tune and mount on my balsa wood plane, they are a tempermantel lot hard to tune .

Have decided to go for a twin engined variety that hopefully is less tempermental , found near lakes swamps ,these engines can hover and are of a larger capacity.

Yes my next prototype is the DRAGON FLY .HA HA HA

We've got several hundred fruit flies in the fridge at work -- we're done with 'em (high school genetics experiment) so any of you wannabe aircraft engineers with very good eyesight and lots of patience are welcome to 'em. They run on rotten bananas, too.

...the trick with the larger animals (especially the previously suggested eagle and or goose) is putting them in the freezer, never mind sedating them enough to be able to permanently fix them onto a plane...

on top of that, they're significantly smarter than a fly, stronger, and more dangerous... AND visible. who'd wanna get in trouble from the law?? at least no one would complain about a couple dead bugs...

If you just used 2 swallows, or crows, or any other bird with a string and a coconut, I mean a thin plank of wood instead of matchsticks you would have a bomber vs those little fly powered fighter jets. Then rig up a coconut to be released as a bomb! If you tried homing pidgeons you could even get a cross country flight!

When I was going to school, we used to make pets of fly's. We would take a strand of hair, mine was much longer in those days, and not so tightly loop it around the head of the fly.
You take dogs out for a walk. We would take our pet out for a fly.
