LOL, Matt, dont even go there, this has been discussed a few times before, and I dont think there is a 'correct' answer/rule. Mainly to do with the T-rex, the newer XLs exceed the 'limits' on here, and really belong in the E-heli forum, but almost everyone stays in this forum.

I believe the original "cut-off" was 400 grammes (saw Toshi state this recently) but with Trexes weghing in at around 700, the point is arguable.

Certainly I am acutely aware that having a 700gm Trex with tip speed over 200kph is a vastly different prospect to having (say) a Blade CP in the same situation... but really they are still micro compared to even the smallest nitro heli..

This is obviously subject to personal opinion, but this is the classification system we've been using on RCgroups.

Micro helis:

These are powered by speed 300/350 class motors and weigh less than 400 grams.
This category includes:

Ikarus Piccolos
MS Composit Hornets
GWS Hummingbird
Century Hummingbirds
E-sky Honeybee
various clones of above
etc.

Mini helis:

These are powered by speed 400-480 class motors and weigh between 400 and 700 grams.
We post these in the micro heli forum because there is no mini heli forum.
Helicopters in this category include:

Shogun/Zap/Zoom 400
Align T-rexes
various clones of above
etc.

Larger helis:

These are powered by Speed 540 class motors or larger and weigh more than 700 grams.
Helicopters in this category include:

Lite Machines Corona
Ikarus Viper 70/90
Ikarus ECO 8/16
Mikado Logo 10/14/20/24
Henseleit 3DMP
Minicopter Joker/Joker 2/Maxi-Joker

When you stand a t-rex next to a 30 sized heli it looks micro no matter what the weight.

A T-Rex 450XL with a 4s setup weighs between 710 and 730g so I guess that makes it a large helicopter.

Darn, Iíve been posting in the wring section.




The Eolo is another helicopter thatís on the borderline between a mini and large helicopter.

The Trex is too popular and is an example of good design, good revisions, and great support from its parent company.

FWIW, I think the above guidelines that iron out differences between a true "micro" and "mini" class are spot-on. That said, I don't think mini's are that substantially different than micro's that they should be broken off into their own category or moved in with the larger electrics. Micro and Mini belong together, as long as we all kind of know they're a little differen than one another, but close cousins, nevertheless.

The T-rex 450XL is basically a slightly larger version of the T-rex which is a micro, so it goes in the micro section to keep all the T-rex stuff in one place.

The Eolo flies on a size 540 class motor and SubC cells, so it's not really a micro.

It's not the size of a mans heli that matters, It's how he uses it.

I still say the Trex should be called a "mini" electric, because its over the 400 gram threshold and uses a different class of motor and larger batt's than the sub-400g crowd. But I don't see an issue combining Micro and Mini Helicopters togehter, perhaps the forum name should be changed to this to be more accurate, esp. since Trex posts are so common here.

I also think the T-Rex should be reclassified as mini and i think there should be a seperate forum section for them.

I actually suggested in the suggestion section that a mini section be set up,but nobody hardly ever visits there so i'm sure it doesn't stand a chance.

I guess i'm just secure in the size of my heli. BTW When rotor blades collide I don't think any one wins. This reminds me of some thing that happened last winter. A real david vs goliath match. A race down a grass runway my 20" Pocket combat wing CD-Rom powered vs sig Cadet Senior .60 powered. Neck and neck at the end of the run I am out in front and get sucked ito the propeller of the cadet. coro and balsa fly and my wing spins into the ground. Was able to tape it back together and fly the same day.

A micro is something you can fly around the kitchen/living room without annoying yoursiblings and parents to much! My BCP is ok in the house, but when my Rex spools up- everyone yells at me!
