Awaiting the exaust kit for my DA-70 (I will optate for muffler because too complicated install two canister in my Extra that need modify the structure… and after moore advice about the “23 into 1 headers” with problem and loss power that these solution can provide) I continued the construction of the TBModel Extra 330SC 2,3mt (
http://www.tb-model.com). And for a good maximodel I decide to installa also a smoke pump for have fun. Certainly I adds a few pounds but the satisfaction is certainly so...
In my recent test I had the opportunity to try some of the most popular devices for smoke, but for my new Extra I decided to install the new pump Secraft (
http://www.secraft.net), the "Smoke Pump V3 ", the latest of Korean company, already well known around the world for quality Rc accessories ,.
The pump for smoke, made entirely in aluminum, in the version V3 is in lighter (155 grams). Was designed to simplify the processing setup and, thanks to a integrated microprocessor, simply to programming. The characteristics are: power input 6 to 12 volts; 2/3 amp. absorption to 7.4V at maximum capacity; pump capacity adjustable from 50 a1000ml per minute with range 0/100%, dimensions of 75x35x35mm. The Smoke Pump V3 Secraft has installed a series of non-return valve integrated, unique feature in the field of pumps for smoke generator that makes this pump at 100% leak proof and does not allow leakage of unwanted liquid.
The pump, which is CE certified for filtering radio interference and it is always recommended before installation, try it out of the model for a test to make sure everything it’s ok. The pump need a dedicated battery pack (if you have a control unit that provide it it’s a good solutyion). The higher voltage allows best control and efficiency of the pump. The cable marked the on / off the pump will be connect intoa dedicated channel of the Rx. In the Tx is necessary have a two-position switch (on/off) optionally combined with a rotary trim that will allow you to adjust the flow of the liquid in flight; otherwise you will have to act to attempts by decreasing or increasing the stroke of the channel. The pump has an automatic device that delays of 2 seconds from start-up to avoid undesirable run before the Tx is on..
