Henseleit 3DNT - Rocket - 3DMP > Last questions before buying

Hello,

Thank you for all the thoughfull of this caterogy of heli. I enjoyed getting informed through the posts and I fell in love with the 3D NT for the compliments, comments and also for the eccentricity of the product.

I'm a beginner in 3D and I practice with a Caliber 30. Slowly it's gonna be time for me to move to something more powerful, more fun to get new sensations too. I find out a lot about all the interesting brands and I keep being hooked by this strange 3D NT. I intend to buy it within the year to experience the moment of adrenalin that you have.

Before ordering everything, I still have some basic questions:

1) Do I need another starter or a new starter shaft (6Hex mm) than the one used for my Caliber 30?
- Should the starter shaft one way bearing turn apposite to the one of a usual heli (like my C30)? Or is it possible to get an OS91 that starts like the most other motors? What do I need?

2) I heard by a man (a little pissed off in another post) that one must reset the needles all the day long when one uses 0% of nitro despite the appropriate Loetterle carburator. Nobody contradicted him. Is it right? Is the engine so unstable?
- I tried 5% of nitro in my C30 with a OS32 and I had a lot of trouble with the needle setting. It was very boring and I wasted so much fuel to find a new good setting every day until I moved to 10% of nitro. I would prefer no to experience this situation again. Would it be better to take another needle for more nitro, 5% or 10%? What would your experience advise me?

Thank you in advance for your precious piece of advice, warnings,.... that will help to make a purchase without worries.

Sincerely

Alex S.

Hi Alex,

Firstly if you buy the clockwise rotation model then you will have to use a different starter 'wand' than the one you use for the caliber as it has to turn the other way. You can however use the same starter though, just connect it to the battery in opposition.

Secondly I remember reading that post and I'm pretty sure he was from the USA - they don't understand the beauty of not using nitro over there as the fuel is so cheap

. I've been using the OS engine and the 0% nitro for a couple of years now and don't have to touch the needle on my Lotterle carb at all. You do hear of people using the Webra 90 having to play a lot with their settings though.

Having said that you can get Lotterle carb needles to allow the use of nitro in whatever % you want but you wont need it as the thing flies so well on straight fuel.

Cheers
Richard.

Hi Richard,

Thank you very much for the fast reply.

Switching the connection of my starter won't help, because I have a fixe starter shaft with a one-way bearing (the shaft would not turn at all).
If I choose a counter-clockwise rotation (as we have the choice), I still may buy the same OS91 and start it the same way as my OS32 isn't (I think one may start a engine in the way we need without adaptation, isn't it)?

If I can't use the same start and shaft, I will buy another starter, because I don't want to switch the one-way shaft each time I switch between my C30 and 3D NT.

Yes, I was alluding to that indelicate (for the censured opinion) guy.

Thank you very much. If there's something else I should pay attention to, please let me know (like waiting for a coming new version,...).

Alex,

By using a CCW 3DNT, you can keep your starter as it is IF it is powerful enough to start an OS91.
If not I recommend you buy a CW 3DNT as you will need a new starter, plus the low profile start shaft provided by Jan.

With the OS91 FX-HGL (recommended by Jan), you are unlikely to adjust the needles of your lotterle carburator, unless of course from one flight session to the next one, you have 20° of variation of temperature.
0% nitro fuel is a lot cheaper in Europe, and 12% of MicroMotul means for me 2€ per liter of fuel, so 1€ for a 15-17mn of 3D flight. Keep in mind that a 91 engines eats 3-4 times more fuel per flight than your OS32 before thinking to use an expensive fuel.

Download the manual from Jan's website before buying the kit.
Just follow EXACTLY the manual, which includes needle setting, Throttle and pitch curves for a 9ZHP and you are 100% sure that you will build and tune your heli so that it flies exactly as Jan's one is flying.

Last point, buy the fiber canopy, the carbon one looks great but is fragile, and the yellow canopy is easier to visualize when flying.

I am flying to Geneva often, so if you are not too far, mail me and maybe we could meet.

Richard,

Not all of us are nitro morons, although I must admit virtually everyone I speak with thinks I'm nuts when I talk about running my NT on 0% nitro and 12% oil.

When I tell them it's the way to go and that I'm going to buy a Laser 4 stroke from the UK because it runs on 0% nitro they are sure I have lost it. Especially when they find out how much more expensive they are over the other 4 strokes. (The US $ ain't worth much these days.)

I don't know what it is about nitro but I think it must be like drugs - once you use it you're hooked. I like the fact that by using 0% nitro we don't have the issues with bearings going sour and the steel engine parts rusting because of the acid that is formed.

My point is, there is at least one of us over here in the US that thinks the way you guys do in Europe. NO NITRO IS THE WAY TO GO!

Generally I think that's true and it's really not worth the trouble. I have wasted a lot of time (and fuel) with a 91FX and the original carb and finally killed the liner. With the Lötterle, the adjustment is done in one or two flights.

But there is one exception: The C-Spec (OS 60K carb) seems to perform much better with low nitro fuels. At the moment; I am using 5% nitro and 15% oil and it's respondig very smooth to any needle changes. I havn't tried 0% because I think thats not the right way for breaking in a new engine, but I don't expect any trouble.

Hi Alex,
if you need more information for the OS and the NT look at http://www.rc-helicopter.org/forum/
There are many post

The starter I used for my os32 (in my rappy) didn't have the torque to start the os91 engine. The startershaft is also different - so its way easier to have 2 starters. I do recomend a sullivan dynatron as it also tolerates 24v for the cold winters.

My os32 run perfectly on the same fuel - 0% nitro 12% oil
