Videos with Hanson 3d-Max 26cc motors???
Hi guys
Just wondering if anyone has, or knows of, any vids of any gasser heli, being flown with the Hanson 26cc 3d-Max motor??
All Ive seen is Preds in the for sale section with them fitted.

Also, does anyone have any experience with the Hanson tuned pipe and header?
Excessive yes, need it no, want it.....
Im a heli hussy lol.

Any info much appreciated guys.
I know someone on here has what Im looking for.
Cheers
For the love of the hobby

Hi Juha
How would you compare the power with a standard Zenoah?
I just want to know what to expect when I get mine flying.

well...
there isnt any reall 'standard' for power. Some like myself say with 710 blades at 11 degrees the motor pulls xyz rpm. most 3d gas guys are 10-11.5 degrees collective top and bottom.

-results may very.

Some people say that there is a lot more vibration with the 26cc engine, something to do with being a single cylinder and a thinner piston wall and yhay they have to sacrifice some of the power because of it. I have not used the 26cc only the 23cc in both a predator and currently in a benzin Acrobat, The benzin is so smooth you can understand why they use them for camera ships

G26
Was talking to the Dr. last night and I checked my pitch and looks like I'm pullling 11 to 11.5 degrees with my Hanson 3D before it starts to lug down hard with SAB 710's. Try doing that with a stock G231 and you will find it will choke alot sooner. I haven't checked max rpms lately but if I remember right you will get 100 extra rpms with a 26 over a 231. In other words, if I'm pulling 1780 rpms at 11 degrees with a 26, the 231 will only maintain 1680 rpms at that same pitch. You gotta drop the pitch to unload a 231 as it doesn't have the same grunt power as the 26. Probably will be equal to 1 degree less of pitch is a good power comparison (for the 231 to spin the rotors at the same speed as a 26).

agree with Raja.
Also a before snap shot of tick tocks on the v2 century pipe and an after on the tuned is obvious. The v2 if I could have shown a video would have been really struggling for power...maybe 1550 rpm on head with good collective managemant using Hanson latest and lightest 26.

I did some tick tocks last night on the tuned and while it does have the power to do it.. it isnt like a Aurora on the g3 sim with un-natural amount of power. It can do climbing tick tocks, but not a lot extra in climbing ability. The weight of the gasser is really a hinder here.

There is more 'vibrations' on the 26. When I first messed with the tuned pipe I found what other gasser veterans speak of the harmonics. Hanson's factory pipe is set for the motor at near 13k according to hanson and I found out what happens when you run near that both good and bad.

Its not vibration for say, but a sine wave..The key is keep rpm low as possible. Too me using a lower rpm with the tuned pipe set for the lower rpm is working having the best of both worlds. Do not dead head the pipe by screwing it all of the way in said Hanson and another guy I spoke with. Most have done this in the past and it transfers the vibrations to the motor and frame more. Many have had the header break. I have not....'yet'.

I used high temp clear silicone from a hardware store as per Hanson and have had no problems coming loose.

Used clean stainless bolts after alchohol and high temp rtv for into the motor.

The pipe makes the bird tail heavy, but on my 1005 I used a large fremco 3800 battery with a vario gas tank. This puts cg near perfect. Otherwise tail heavy rolls look Fugly.

Raja I may try numbers at 11.5, 11, 10.5 collective for max rpm.
