I wanted to post some more pics of the Thunder Tiger Mini-Titan e324 helicopter for anyone who might be interested.   The kit is an Ace R/C Mini-Titan e325 and is the non-SE version. The Mini-Titan SE comes with all the aluminum blingbling you could be interested in.   The 325 is relevant to the length of the blade, but is a 450 size electric helicopter if you go by other peoples standards such as the T-Rex and so on.

You can click here to see more pics of electric, nitro and gasoline powered R/C helicopters I own or have owned (new window) from my helicopter site.

The picture below is of a nitro-methanol powered helicopter I owned, provided as a comparison for the smaller electric one which is the subject of this post, and pictured in the gallery images below it.

The smaller electrics like the Thunder Tiger Mini-Titan and T-Rex 450 are great for a quick quiet flight in a small area where you wouldn’t want to fire up a nitro-methanol or gasoline combustion engine powered model helicopter.   Though they tend to have quite a few benefits, they are not really neighbor friendly, and it’s not really safe to fly them in tight quarters. If you are in an environment that allows nitro-methanol, I’d certainly look deeper into the advantages and disadvantages of both types.

My Mini-Titan e325 runs the stock ACE brushless motor and ACE brushless electronic speed controller included with the kit.  The blades, as seen in the photo, are Align 325 Pros.  They are wooden blades, but perform decently.  The stock kit blades are very heavy and not that great, though you can do your initial setup with them if needed. I’ve recently dumped the Align pro’s and switch to a generic carbon fiber 325mm blade type that I get from heliflightcenter.com for $17 a pair (and I get heli-reward points!)

My ACE Mini-Titan e325 Setup as of This Posting:

Radio: Futaba 9CHP 9-channel computer radio
Receiver: Futaba 149DP 9-channel PCM receiver
Servos: 3 Hitech HS-65MG metal gear for the cyclic and collective pitch on the main rotor
1 Futaba S9257 Digital Tail Rotor Servo
Gyro: Logitech LGT-2100T heading lock gyro (for the tail)
Flight Recorder: Flight Data Recorder from Eagle Tree Avionics
Brushless Motor: Stock ACE Brushless Motor
Brushless Speed Controller: Stock ACE Brushless Electronic Speed Controller

The Eagle Tree Flight Data Recorder records voltage and current used and allows me to graph out power consumption from the motor and servos on my PC so I can see how to better tune or improve the helicopter towards better performance.

The cyclic and collective on the main rotor is controlled using eCCPM (electronic Cyclic, Collective, and Pitch Mixing).  eCCPM allows 3 servos to perform the same function as  4 to 5 servos in a mechanically mixed system, but it requires stronger servos as the load from the head is the same as it would be with 4 to 5 servos. eCCPM is pretty much the standard these days.  My older Nitro Raptor 60 and Nitro Raptor 50 used mCCPM, mechanical mixing.

Please check out the photos below for some pics of the Mini-Titan’s internals, it is a bit dusty, I was hoping Sunday’s flight would help remove some of it, but I may just need to use some canned duster on it. I also have a number of other posts relating to the Thunder Tiger e325. You can find them below under related posts or use the search bar at the top of the screen. Thanks for visiting!
