Hi Guys, after too long looking at frames and motor sitting on the shelf, I have finally made a start on a helibug conversion. I have pretty much test fitted everything and have chased up all the odds and ends needed to finish, only thing I am not sure about at the moment is whether or not to run a govener, leaning towards using one, which leads me to the next question, I have not picked up a gyro yet, so after looking around I am led to believe that a v-bar or some other FBL units can do the tail the fbl and the govener, is this the case? And can I use a v-bar or another unit for the gyro and govener, but not the fbl side of it till after I get this heli up and flying and eventually put a fbl head and blades on it??
If this is correct what is a good fbl controller that has a govener that is compatable with a gasser??

Currently

I'm using the Demon 3SX with Futaba GV1 governors. The Axon is coming out with a governor though I'm not sure how well it works with gassers. I'm going to test one, can't tell you now good or bad as of yet.

You can fly the Demon with or without flybar, and I would certainly use a governor, the machine will fly alot better with a constant head speed.

some other FBL units can do the tail the fbl and the govener, is this the case?
the CGY750 can do all three,...

but before you go "there", what transmitter are you using? its best to go with a FBL controller that suits you Tx if possible.

I use a CGY750 cause I use a Futaba Tx that can take advantage of the built in features the Tx has to manipulate the CGY750...

honestly, its hard to say which direction you should go... you could use a GV-1, but those are no longer made, yet they can be had cheap. Same goes for used V-bars....
If you plan on going FBL, you might as well get good servos suited to a FBL system now instead of buying standard servos that work ok with a FB head you currently have.

Raja is your go to guy for gassers, few others are as dedicated as he is, Carey Shurley comes a close second who also very active into gassers, but he is bound by manufacturer restrictions as he is sort of a designer/contractor/resale as to what he can say/recommend online... he is most active over on the freaky site with his own section.

showing a preference will only get you into trouble, 90% of everything is crap...

You'll have good luck with the governors in the GY750, GY701, GV1, Skookum, Spartan and Mikado Neo. Others may work fine I KNOW these do

Thanks' for the feedback guy's, I will decide on a controller after a bit more reading. I will chase up a fbl head,looking at this one H70H002XX, unless any one thinks there is better/cheaper around? I will lookaround for some servos to suit fbl.I totaly understand the HS 5645s I run on my 700N just not going to cut it!

I agree, these two fellows have a lot to offer.

To add to your observation, note that in the past, Raja was associated with MinAir USA and I suspect now has an association with MinAir Germany as they have sent him a pre-production kit of their latest gasser offering. He also was/is associated with Hanson engines so he is definitely the go to man if you have any questions about products from either of these two companies.

Carey has experience with many different brands and gasser products over the years, due to his forum on the freaks where he revues many of them. He has also been involved with many different heli designs, including some MinAir ones, so he may have a much better overvue of more products related to our gassers.

Other fellows who have gained a good bit of experience with various gasser helis, engines and electronics are fastflyer20, jharkin and yourself RM3

Hi guy's well I am have gone and picked up the screws to hold the shroud mounting plate to the motor. Now to go thru my collection of screws to find some to hold the shroud on! But progress none the less.I have not ordered servos yet as I need to see if go with a fbl head or not. Ordered a Hatori muffler today, I just cant see my self running a can muffler. I am stuck with the head though, I dont want to startr a flame war ,but have read it might be good to stay away from the Align dfc head, I dont know how much stock to put into that, as I only sport fly anyway. However I have had a look around for a conversion head, but no stock as I think the trex is getting on a bit. Can anyone recomend a fbl head that works?
PS Looking at a Align DS655 for tail and DS615S cyclic?? Are these quick enough and grunty enough for fbl on cyclic, or am I looking for something quicker on cyclic

Those particular Align servos are not up to the task on a gasser. It is not the speed, but rather the durability.

MKS are also a good choice.

I hear very good things about Xpert servos, I may try a set.

We are all a product of our past experience, I had a high failure rate with Futaba. 3 out of 6 BLS 451's died in less than 2 years and a 4 month tail servo failed.

Torq, no longer available, were made by MKS. The tail services would not last long but the cyclic were incredible. I still have 3 cyclic sets years later being flown regularly. It does indicate that brand alone does not tell the whole story.

Futaba bls 451 are no good Tom

I was going to post that earlier but I figured I said what is good skipped over all the bad stuff I have tried in the past years...

Picked up a used E/C GY750 w/gyro today for $150 AU, but no rpm sensor, so will sort out which way to go. Pretty happy, now I will start looking for the servos.

Hi Guy's, One more question, I am after blades for the 700. 26 hanson pro motor, sport fly, the odd roll or flip. For these gassers is something around the 690 mark or up to the 717, 720 mark?

not sure I saw which drive ration you have, but I'm assuming its probably 6.8ish. If so I'd stick with something in the 690 range

I would have opted for larger blades

Would lower your disk loading and improve auto hang times.

710 would be my minimum choice and if you could fit and use 716's even better. Hanson 26 should be able to swing either, I use 716's with my Hanson 26 and 300 motors. Gear ratios not a huge deal, I fly from 6.43 to 7.08 between 5 different models.

Gear ratios not a huge deal
as with any source of power, drive ratios are the difference between high performance and average to poor performance.

if it didn't matter, every helicopter with every power source would just use the same drive ratio to save costs.

The ones I have

I have the 1005 with 6.43 gear ratio
Then I have the Raptor with a 6.77 gear ratio
Also the Whiplash V1 at 6.89 and V2 at 6.88
And finally the Spectra which was stock at 7.15 but I made it 7.08 because I think that's too high / too fast for the motor unnecessarily.

In any case, I can setup all of them to fly well, regardless of all these gear ratios. Some have more and some have less engines, they all lug and pull well, the ones with stronger motors can climb faster.

From my experience, they all lug and fly pretty well after I'm done with the setup on them, can't honestly say this one flies high performance and that one is poor.

I'm not saying it doesn't matter at all, what I'm saying is that its not such a big deal. Once you find the right rpm your model is happy at, the next one might be happier at a little higher rpm or little lower due to the slight difference in gear ratio -- its not like we're going from 5.25 ratio (old helibug conversion) to 7.29 (whiplash GR high option), its more like 6.8 +/- 0.35 give or take.

I recieved an email from the vendor i ordered the blades from, that they did not have the blades I ordered, so I have taken a punt that I can squeeze the 717s on to the align FL head and clear the tail. But have alsl ordered some 770 incase!
