Hi All,
Since there are enough gassers power plants out there now of all different configurations my question is this. Is a Hanson Pro modified 260PUH as smooth as a 231 PUH (whether the 231 be stock or Hanson modified). Obviously the Hanson 260 has more power, but does it come at a price (more vibration)? Im just trying to decide if there is really ANY disadvantage in going for a Hanson 260 vs. a 231 in terms of vibration since I cant think of any other cons associated with going for a 260. Is the fuel consumption notably different....like it matters :-) compared to glow fuel.

Guess Ill answer my own question

Guess the only significant difference between the two...other than power would be the price. Im assuming no one seems to think vibration in a balanced 260 is significantly different from a stock 231.
IMHO, from reading a lot of posts on RR, the 231 has plenty of power for all types of flying. More power allows the pilot to perhaps be more lazy/sloppy as it is easier to recover or power out of an undesired orientation. More isnt always better, its harder on the equipment......but then again, some people like 500HP cars to go buy groceries with....to each his own. If Ive totally got the wrong perspective on this ....someone set me straight.

Spoke with Mr. Hanson this morning.

If power and smoothness is what you want, get the Pro-260. According to him, the 231 is not as smooth as the Pro.

Now, If you want mad, crazy nuts power....go with his 3-D Max 260

You will like it.

I believe it is worth the money to get something that is tried and true.

Hanson motors are definately nicer

You can always tell a Hanson motor from a stock motor. The stock 231 is balanced better than a G23, but not all 231's are the same. Some are better than others, balance wise.

When you get a hanson motor, it is balanced and it will run smoother and with more power. I have the Hanson Pro 260 now and I'm loving it. I was part of the debug team, and I went through 2 engines R&D before Bruce got it right and running like it should. He modifies them and installs his own piston now, as the stock piston was not lasting.

Anyway, I also fly helis for MIT. The MIT helis have stock 231 motors in them. I can see the tail fins buzzing when I hover with a 231. Some buzz more than others, (I have 4 to compare, seen 3 fly 4th still NIB). When I fly the Hanson motor, the first thing I look for and notice is no buzz in the fins. This is my tell tale sign that the engine is balanced well and smoother than stock.

I also have a Hanson 3D motor, but it is still NIB. I plan on putting that one into the new spectra-G heli. My current gasser I bought back in 1997 and I've logged 1224 flights to date with it, still flies like a champ (was out loving it today), but now that I got the 3D motor I need a "body" for it. Can't leave it on the shelf!!

Definately without question GO with the Hanson modified motor. The PRO is his smooth version, the 3D will vibrate more he says since its higher compression/more power. I got it to try it out, and to blow away any nitro competition some day, but for now I am really enjoying the Pro 26, and the extra power is worth every penny.

As far as fuel consumption, the biggest hit you suffer is changing from a 167a carb to a 643 carb. The next hit is changing from a G231 to a G26. On my 10oz stock tank, I could run a G23 or a G231 with a 167a carb for 30 minutes. Going to the 643 carb cut that time down to about 23 minutes, and, with the G26 I think I'm down to about 20 minutes. Hey its still longer than 15 minutes, and in general I'm always ready to land after 15, all on a 10oz tank using about 8oz per flight.. If you fly the Predator it comes with a 22oz tank and you can get 30 minutes with that on a G26 PRO.

Hope this helps,

-=>Raja.

Hanson it is then

Hi Raja,
Sorry for the late reply. Thanks for the extensive feedback on the Hanson motor. I too will now be a 260 Hanson owner. Where I live its difficult to find the same pre-mix you guys use. I have been able to find Yamalube marine and mobil 1 synthetic pre-mix. Im not sure if the Yamalube is 100% synthetic, I was told it is, but it doesnt specify on the bottle, which is actually in English. Any comments/suggestions between the two choices would be appreciated.


Regards, Johan

Johan,

Do you have Motul up there? They do a large range of synthetic 2 stroke oils.

I am experimenting with some at the moment on my gasser but it is too early for me to recommend it to you.

Sorry no experience with the 2 oils you mentioned.

Regards,

Paul.

Yamalube

Hi Jonan:

If you can find Yamalube R2, that is great oil that I used for 800+ flights and it always took care of my Hanson G23 at the time. Since I got the G26, I also got some Blue Marble per Bruce's recommendation, but he still states to break the motor in with a gallon of non synthetic oil and then go to Blue Marble (fully synthetic).

If you look at the Yamalube r2 bottle, it does say semi-synthetic and I used that straight from the beginning with my Hanson G23 motor. So if you can find that, you can use it no problem. I would put between 4 and 5oz per gallon. Start with 5oz per gallon, go to 4.5 after a couple of gallons.

Be careful you get the right Yamalube oil. Yamalube marine doesn't sound like the same thing I used. If you can post a picture of the bottle you have, I can tell you for sure if its the right one or not.

motul oil

Hi Paul,
I have been unable to find any Motul oil up here. There are thousands of two stroke motorbikes running around but most opt for the cheapest possible oil. Looks like Ill have to find a racing shop of sorts and see what they have.

Yes it is the same here.

I buy my Motul oil directly from the importer as most of the bike shops only stock the semi-synthetic 510.

Good luck with your search!

Regards,

Paul.

mobil one 2t

Don't worry about the motul.. Great oil but so is the mobile one synthetic 2t
Use it by the bucket out here racing in motocross and in my gas baron 'till I got a supply of castrol TTS....For free.
Yamalube ok but not quiet up to it in air cooled motors.designed for water craft.
I'm a Rotax aircraft engine tech out here working on the 2strokes and fours on planes.
Also tried polaris full synthetic gold ..seems fine in the microlights but there water cooled.
Used motul in the UK great but supply sucked.

2t oil

Hi Paul and Rev Man,
Thanks for the input. Thailand is a unique place in that it has everything you could possibly need, you just have to find it. I live a little bit in the middle of nowhere so Its quite a trip for me to go into Bangkok or any of the markets to find oil. But I think the Mobil 1 may not be a bad idea, Ill stop at the next Mobil station in the area and see if they have any. I found some Castrol R2 racingbike oil that is supposed to be 100% synthetic but only in a 100ml bottle, the search continues. Rev Man, good point about being careful about using oil designed for liquid cooled engines vs. air cooled.


Regards, Johan
