G'day gang. I'm finally get fairly decent at this heli flying lark and I was thinking about doing some F3C comps next year. I don't have the money for the high end 90s like the Milli 3 or the Xcell 90s and after seeing the fuel a 90 on 30% drinks I doubt I could afford that either. Orginally I was looking at a Raptor 90SE as my budget comp machine, I just wanted to do F3C for fun, not a serious competitor by a long way.

A gasser is looking like a good choice, economical and longer practice flights. The one thing I have not seen discussed is doing F3C with a gasser model, is a gasser ok for F3C?

Also heard the gassers suffer from vibration issues, urban myth?

I was looking at the predator from Century as my Gasser of choice.

I think the vibration myth was started by the nitro guys who didn't want to get beat by a weed eater engine. I have a vario benzin with an unmodified g230rc and it's smooth, and hovers like a rock. The hanson 26 pro is supposed to be really smooth.

Your thinking the same thing i am on doing fai class 1 with a gasser, only problem for me is my vario weighs 7600g "16.6Lbs" and my new predator is coming with a hanson 26, the rules say no more then 6000g "13.22Lbs" and maximum engine displacment of 25cc, so keep that in mind if you buy a gasser for fai.

Never go full retard!

Weight
you should have no problem getting under the 13 and change weight with the Predator Gasser, especially the carbon (which is a 1/4 LB less). Note the 231 engine meets the size restriction. I agree, this make it an excellent choice for your machine, and the fuel costs are negligable.

Fantasic reply thanks. Wasn't aware of the weight or CC limits. I was thinking about the hanson 26 pro in a predator carbon as well... That throws a bit of a spanner in the works, might have to go with the 23cc version but would rather not.

I plan on contacting the governing body that throws down the rules and see if they will change it to 26cc, as most enigne's are either 23cc or 26cc, not sure why they caped it at 25cc.

Honestly
your not putting yourself at a disadvantage with the 231. I realize the "big block fever" has showed up on the gassers as well as glows, but I have been running the 231, and can tell you that it can be geared up and set up to hang with the big'uns. You might notice a difference in hard 3D stuff, but FAI?? Naaaaaa. Don't sweat it. If you decide that the 231 isn't enought, you can send it over to Hanson......he will turn it into a 26 3D Pro version for $200 USD. I'm going to keep that in mind IF I ever wear out my 231 (and the odds of that are darn slim). Maybe after 40 gallons I'll just treat myself.

Dankers, i just noticed your from austraila, the specs i told you about are from the AMA here in the states for class 1, 2, &3, you will have to check your countrys/local rules to see what applies to you. The only class that is world effected is F3C and that is controled by the FAI. I did not check on the specs for the other class's.

Aha, but what about when I'm competing in the world championships?

We use FAI rules too and I have just checked. 6kg and 25cc, why 25cc when engines are 23 and 26?? This should be changed for sure however, does 25cc mean 25.0 cc ? The G26 is actually 25.4cc - I'm sure its 25.0cc dead on as the os91s are 14.95cc and were made when the FAI increased limits on 2 strokes to 15cc.

Might have to go with the 231 however, FAI does indeed need power or a real good pilot.... Wonder if the 231 can get a super charger fitted :-)

It's like AGRAV8 said, for FAI stuff you probably won't notice the differance between 23 and 26, only in hard 3d.

I guess we could sneak the 25.4cc engine in. Not sure how they do tech inspections but if it follows any other compitetion scheme they only do tear downs if you win!

Hi Danker
I switched from a 231 to a Hanson pro 260
mainly due to probs I had with the 231
the Hanson is smooth but as far as power goes its hard to tell
the Cuatro was fairly ballistic with both engines
I have it geared for approx 10,000 rpm but the hanson is supposed to be able to produce 5HP at 17,000 so my guess is with a change in gear ratio I could get nearly unlimited power from this engine
but I have enough and prefer to have a reliable and long lasting engine
dont be put off the 231 is still a lot more powerfull than the older 230
engines and the difference between the 231 and the 26 in my opinion is not great if much at all
if you are interested I have a new 231 engine in a box over here
it was replaced under warranty as the first suffered damage due to the wrong carby being supplied with the engine
in the mean time I bought the Hanson I will let it go for $300
Cheers Michael
