To Date my highest Tracked and closed 1/8A SD flight is 318ft.
Lowest flight is a 21g single motor 1/8A BT-5 downscale that only got about 8ft. Altitude is not always the deciding factor in building or flying. Sometimes it's the Skill and challenge of building super small.
To be more precise To date there are Micro-Maxx models that can and do fly in every single event in the NAR Pink book (model Rocket Sporting Code) except Egg loft. the current 1/8A Helicopter Duration National Record is 64seconds but many of us have had flights over 2minutes in this event we just haven't been able to return one yet. Same goes for 1/8A flex wing glider I've had multiple over 5 minute timed flights but have yet to chase one down for a return that would secure another national record.
As far is Scale. you would be amazed at the number and size of subjects that can be made and the degree of detail can rival that of standard and Gaint Scale models.
Plastic model conversions of all kinds of Jets, missiles and rockets are being done with precision and plenty of detail.
there are any number of Boost Gliders. Parasite gliders (1 to 3) and Rocket Gliders. there is even a Micro 1/8A RCRG.
Small Fields are Ideal for Micro Flying but don't for one minute be fooled into thinking their is no excitement in building or flying these little marvels. 2- 7 motor clusters can put these small models out of sight in an instant. Staged models "currently" can be breath-taking as our "booster" motor is really just a MMX-II motor the Quest after market removed the ejection charge but left the .857s delay. On heavier combinations that Delay before ignition of the upper stage can give one a little heart failure
There are quite a few Kits out there by several manufacturers if you look, Fliskits has by far the widest and most complete selection of kits, and parts. but there are also kits still available from ASP, Micro Classics and a couple others. Not to mention more the 150 different 1-page Plans for anyone who want to use available over on the MicroMaxRockets Yahoo group file section.
Micro are Almost all I fly anymore....why? How many rockets can you take to the launch field at a time 10 or less? I generally have over 150 different models with me to choose from at a moments notice. I can fly and recover 10 to 20 within a 6 hour launch day depending on the crowd. and best of all. each fight is costing me currently .49 cents. All the excitement many out of sight, almost all recoverable without the spending a ton of money.
I've said for more the 10 years now " Out of sight is out of sight, weather it's at 300, 3,000 or 30,000 feet makes absolutely no difference". Only thing that changes is the amount spent to put our models there
