Hi guys I'm thinking of converting one of my trex heli's to gas.
Can anyone give me advice on this conversion?
I'm a fairly new pilot so I dont stick bang and dont think I'm going to fly like that I've seen lots of videos of the conversion and would like to jump in and do it to my 600n or my 700n
if anyone could help me with used parts I can buy them just dont have a lot of money and I'm not asking for hand outs so please dont think that's what I'm doing.
what one should I convert and what engine should I use?

thanks for all your info

It would probably be just as cheap to just buy a good used gasser then to try and convert one. There are several for sale right now in the classifieds.

Which is worse, ignorance or apathy? I don't know and I don't care!

I have the kit HB7-RC with the G270-RC. When I fly with the canopy the engine temperature reaches 135 degrees celcius. The servos also just above the engine get too hot to. When I fly without the canopy the engine temperature stay at 110 degrees celcius. Did you cut your canopy? You have a similar problem?

here is the video for the first flight...
There is a flaw in the heat .

Indeed, that is the way to go.
Gassers are built very rugged, as many are intended to be used as utility helicopters.

The old Miniature XCells, and all Bergens are great helis.

Converting a glow Trex may look like a fun project, but nor the chassis, or geartrain was design to work with the weight or the vibrations or torque of the gassoline engines. The growing pains associated with the conversions and the off spec nature of parts not designed for that use may cause you a crash in the long run.

Take this advise seriously.

If you are a capable builder ,confident in your abilities,then the heli-bug conversion ,if you have the 600 and 700 already and have plenty of spares seems logical,the frames are replaced with the conversion kit and a 23cc RC motor would be enough for a steady flyer.Setting up any gasser is different though and takes time and patience if you have only had nitro helicopters.Do a bit of research and make your own mind up,spares and cost being a major issue with many gas helicopters in this day and age,just like expensive fuel

Buy a gasser
Absolutely phenomenal. I was out flying mine today to music and doing pirouetting maneuvering all around the sky and I realized I had total control in all the orientations. It takes a long time to get there, but when you do and you suddenly realize it, its a great feeling!

I have a helibug conversion zen 27 R C with all align electronics . It flies grate do not use the carbon fiber boom use all aluminum one cut a 3 inch scrap of old tail boom split it make the slot big enough to slid it inside the heli end of the boom slid it past the alinement slot locktite it or epoxy it in place . If I were doing it over I would get the zen rc 29 . I love my gasser 30 minutes on a tank that worth 40 cents not 5 dollars its big and heavy it gives you time to think .I have had no problems other than soft screws and a tail boom failure witch the sleeve fix . A stock motor will be more reliable . They didn't have the 29 when I did my hb 700 trex but i love it

I *WOULD* be broke if over the past 13 years of heli flying I did all that with nitro!!! A quick calculation yields that I would have spent $38,220 in fuel costs

I had one of his 60 engines back in my pattern days and what a sweet engine it was. Was at a contest in NC, on the starting line, connected the glow power and a breeze blew the prop over, it started right up! lmao. Nice to hear that name again. Brings back good memories.

You're a given, I envy how much you fly. But I know some nitro guys who complain about the cost of nitro, but only fly a few gallons a year anyway.

I am looking at a Helibug kit for one of my T600's.
I ended the year at 38 gallons of nitro through 3 600 size heli's plus many electric flights on a T500.

There are days I just want to cruise around and a gasser seems like a nice addition to the fleet.

You will find that some of the current gassers can do more then just cruise around.

I like to fly 3D and have been doing so with my Predator gasser that uses 710mm blades since 2005 and now with the smaller Radikal that uses 620mm blades all last summer.

Cost per hour of flying for fuel - is about 1/5th of that for a small nitro powered 30!
