I took the plunge! Never thought I would, but here we go. I picked up a older MA X-cell 99 SE, built around the YS-91 ach, 4 stroker.

I've had my fair share of 2 stroker motors in Rc surface machines, but never a 4 stroke. I guess my question is what kind of feild equipment should I be looking for here? Starter, fuel, small batterie charger, tools,,. Pretty sure it cannot be this easy,, or is it?

All of the nitro tools are the same as RC nitro surface machines.

You will need:
1) Starter and battery (cordless is the better way to go since it s all in one).

2) Glow plug igniter (or onboard remote glow igniter).

3) Battery load tester (since you are not putting in a fresh battery between flights, and you need to test between flights)

4) Fuel (Read the manual to see what mix you should run, it is diffrent typicaly for 4 strokes)

5) Fuel Pump (hand or electric work fine electric requires a 12 v battery)

6) Quick Fill Fuel cap (one that fits on gallon of fuel, that has the fill hose that is part of it like this DUB8077 http://www.largescalerc.com/dub807-...capfitting.aspx

7) Two or three extra glow plugs

8) Glow Plug wrench

9) Simple green and a rag (for yummy slime)

Oh Yeah
I use 4 strokes on my planks they start and run the same as a 2 stroke. 4 strokes just have cooler glow plugs. There other design diffrences but that isnt really that important at this stage.

I saw the post of the heli you bought, it looks very cool.

Most 4 strokes need a longer glow plug starter due to the valve cover.
On board glow would be ideal.

Heli fuel may be best as it has more oil than most plank fuels, something a heli needs since they run hotter.

Heli starter wand on a standard plank starter

If you ran car engines, then you know the rest of the story.

It would be cool to see video of it flying.

Yup, seems as though I will get more air time vs. My electric helis for sure. Thanks for the lists.

dont forget 4 stoke engins are good on fuel so you will probably get more time than 2 stokers

Tuning is a little different with 4 strokes. They do not like to be lean and will shut down in flight if they are even a little lean. The airplane rule of thumb is to use a tach, lean to max rpm attainable and then richen for a 200 rpm drop. A helicopter will be a little different to tune obviously so I don't know how you will achieve that. 4 stroke do love heli fuel, especially the additional oil. I use to run my 4 strokes on 15% syn/castor blend (because I liked the smell) but now I run them on heli fuel. They really rip on 30%. You don't have to be a needle happy either, once it's running good leave the needle alone unless you love doing forced autos. If the temps drop by a good amount you can richen by a click or two.

Maintenance item: You have periodically check the valve gaps, they lose noticeable power if the gap ends up wrong.
