T-Rex 700 Gasser whit Helicommand 3D FIRST TEST (almost CRASH !!)

[amiraldz1970]

i find this with futaba

watch?v=R1McWVIL8No

[amiraldz1970]

hello krumrick2

i have the same configuration of that heli, but i have some problems with rudder, i'm using aurora 9, i have 15% gryo gain but still moving,

can you give me some instructions please?

ps: i use the align 780 gyro.

[krumrick2]

@amiraldz1970

Hi, look...I do not recommend the Helicommand integrated gyro, is not good to secure the tail in the gasser 700's ( not even in electric one).

The best gyro I ever tested to this gassers are the Futaba 611with 9256 tail servo, pretty old but really nice gyro.

A few days ago I installed one of this in another Electric 700's with Helicommand Rigid, same problems as yours, the tail is not firm enough.

[amiraldz1970]

@krumrick2

thank you for the answer,

I misspoke, my English a little bad

I wanted to know what the gyro is better for TREX700 gasser, because 780 of ALIGN, I do not like much.

@amiraldz1970

Don't worry...my english is not good to rsrsr.

Now...gasser helicopters have serious problems in tail control ( lot of wag), the best gyros for me are Futaba 611 with Futaba 9256 tail Servo.

@mark675

Hi, take a look at Century Heli USA, they have a really nice conversion for the 700's.

If you need any other info and tips send a personal message with your e-mail.

What kind of fuel do you use, I notice you didn't have much smoke out of the exaust.

[krumrick2]

@lazarra101

hello,

I'm using car fuel with two strokes oil ( for motorbikes), that is the low smoke exaust .

Hi,

I've tried and used all the positions in many helis with Helicommand, from 3A  to Rigid versions, all positions ( rear, left, right, and front) worked well, no differences.

In all this mounting just one time I used the Computer to make changes in the setup.

This 700's is just fine, but later I mounted another one that with the same position (front) and was fantastic, the "Position Mode" worked 100%, more than 5 minutes without leave the point of hover ( just one meter drifting)...

Hello my friend nice fly your trex 700 gasser.... but your helicommand you put in your front of helicopter; its not good my my friend... never put the helicommand in the always in the left side my friend..try my friend

[soverato3]

why is your gas blue ??? my gas for normal 2 stroke gas engines is always yellow

[krumrick2]

@soverato3

The blue color is for the oil in the gas( Castrol Two Strokes Oil for motor bikes), the gas is yellow.

[BCPCX]

Está usando qual gasolina?

[krumrick2]

@BCPCX

Sempre uso a mesma em todos meus gasolina.

Gasolina PODIUM com oleo CASTROL TT na proporção de 25Mls por Litro ( depois do motor amaciado).

[ivanbegfly]

Hi what RPM you have on motor and which pinion you use?

[krumrick2]

@ivanbegfly Hi...I can not say yet what RPM i'm actually reach in the motor, but the pinion and main gear i'm using the 700 nitro stock.

Measured with the Bantam Heli Meter the rotorhead speed fixed in 1600 ( after a few adjust in Throtle and Pitch curves), more than that create a serious vibes can only be noted in the tank ( seeing the gasoline look like a blender), this vibe directly affect the gyro response.

[uncaljeff]

what conversion kit did you use ? it seems hard to find the info online, thanks !

[uncaljeff]

please tell us how was your conversion experence ? i have herd only of heli bug and gasser man who sell the kits, what was it like for you ? beatuiful machine. thank you.

[krumrick2]

@uncaljeff Hi...about your question I only have good things to say about the kit and flying this 700's converted to gasser, this is not my first gasser ( one Miniature Aircraft X-Cell 1005 with many upgrades and one Miniature Aircraft Spectra-G) I will post videos of this helis tonight just to compare.

Back to the 700's gasser is a pleasure to flight even with Helicommand not correctly adjusted yet. I RECOMMEND FOR SURE !!.

[carpclubspain]

Make sure you get an in-tank filter/clunk on there before your carb gets all bunged up. Another foaming tank problem...

[krumrick2]

@carpclubspain Thanks for the tip...I see you have a Spectra, I have one to and I will post a video soon as I buy a new canopy ( the original was modified to put a camera in the nose).

[Flight1142]

Hi @krumrick2. Very nice helicopter. I am beginning to fly a T-Rex 700 nitro equipped with an YS .91 SR but operation is extremely expensive due to high cost of glow in my country. Can you tell me where to find the conversion kit you are using? Thanks.

[krumrick2]

@Flight1142

search the google for: T-Rex 700 gasser conversion by Heli Guy, or the Gasserman gasoline conversion, I can not post links here, this two are similar and use the same engine Zenoah 231 RC
