I purchased the conversion kit and full kit that was prepared by SAB for gas powered helicopters. By doing this I saved some money( ah money) and received only the parts needed to build the gasser. I have no plans to convert the model to electric down the road.

Raj,

I actually went to Home Depot yesterday to look for a t fitting for the plumbing. I think they may put away small engine related goods for the winter because I couldn't locate much. I must have gone through every bin in the place looking for a fitting with no luck. I was supposed to be out Xmas shopping. My only concern this week is to get this model in the air

The conversion is a Leviathan Design product designed by Joey Chan in Australia. Smart guy, does things right the first time.

Available for the Goblin 630, 700 Standard, 700 Competition and 770 (each with different drive ratios)

T fitting - will start including in future fuel tank kits, have to get some first

Thx Carey. T fittings are hard to find...

Here's the link to the full kit. I have no affiliation with anyone and IMO this is one of or the best gas model available. Carey has documented every step of the build and is always available to answer questions. If anyone is on the fence you can't go wrong. The model is so nice I'm afraid to put fuel in it

I was waiting to see if there would be a kit...
and wanted see others take the leap
Going to try and save up for 1 this spring I really like the looks and always wanted a decent gasser

Does the canopy affect the motor temps at all?

Yes the canopy helps decrease the temps!

I was very concerned too, but it turned out just the opposite, the heat deflector pushes the heat past the tight fitting canopy, on other gas heli's more heat stays inside the looser fitting canopies.

A word of caution regarding the canopy on the comp 700 version. I had to remove the front frame spacer below the fuel tank. The hex screws stick out only a few millimeters but make it very hard to slide the canopy on. My canopy from SAB is very narrow. Others may not have an issue...

On the original version, the front of the canopy fit OK but was wearing due to the same bolts. I replaced them with button heads. The tank rubber edging now sticks out further creating a nice cushion for the canopy.Tom

I also had the same trouble with the canopy rubbing on the front screws . I found these screws in the Traxxas car line . they help reduce the problem . Traxxas part #TRA4859
With the molding of the canopies , I think some may come a little tighter or a little looser on others .

I was able to maiden the model yesterday. I need to isolate my fbl controller a bit better. The heli twitches occasionally in the air and I am using two layers of 3m tape. I also haven't gone to full throttle since I am slowly breaking in the motor. Also, the fuel clunk sits at the top of the tank and runs lean on slow circuits because fuel isn't sloshing around to submerge the clunk.. I'm not sure how to fix this. I plan on continuing the break in today. Here are a few more pics:

Very nice Andy ! Congrats! Try making your clunk line shorter, or make it longer and do a "U" in the line so the clunk sits down in the bottom of the tank and is always submerged in the gas. Enjoy! She's a fine looking helicopter! "Everything's better inverted"

You will have a great time with this heli . Always fly's rock solid in the air ,and a pleasure to fly .
On your fuel tank issue . Are you using the black fuel pickup line that came with the Zenoah motor ? Or are you using the yellow fuel line in the tank ?
I always use the black fuel pickup line that comes with the motor inside the tank . It is more flexible than the yellow Tigon line .
With the black line , the fuel clunk will dance around the tank to what ever position the heli is in keeping the clunk submerged in fuel .

Good luck with Your Goblin Gasser .

Thx for the suggestions. I resolved my fbl issue by adding one layer of 3m tape, a big metal washer (I don't have a suitable metal plate), followed by two more layers of 3m tape. No more strange twitching. One of the main reasons I wanted a gasser is long flight times but I'm finding that I'm only getting approximately 7 minutes which Imo is terrible. I am not running the motor wide open yet only at 60 percent. I have ran two gallons and plan on opening it up a bit today. I am running the g270rc modded by toxic al. I am curious to see what others are getting for flight times? Also, there is oil leaking from the top bolt that holds the muffler. I did not use any type of sealer when I installed the pipe. Was I supposed to?

Permatex Ultra and no gaskets work for sealing the mufflers.

As you lean out the engine, flight times will go up.

Fuel consumption remains high, flight times depending on tank size...with the same engine and the stock Trex 700 tank (approx 500ml), i am getting 30-35 mins at 12500 engine rpm

Can only fit a smaller tank, average flight times around 12 minutes from what I hear.

designed specifically for a 14oz tank so flight time is dependent on engine size and RPM.

however consistent performance for 12 minutes would be about 4X what you get in its electric configuration......:-)

Hmmm. My engine is the modded 270 and I have the needles set to what's recommended by Zenoah. Sorry I don't have access to my heli at the moment to give you those numbers. I just sport fly and I can only squeeze out at most 7.5 minutes. I was actually trying to find a video of someone getting more minutes than me but couldn't. Damn something is screwy. I do love the model. My knuckles are burned off though. I'm still getting used to a muffler while removing the canopy 😜

Imo this is the best model out there....
