Hello!

Just ordered new YS 63S engine for my 3D plane. Could you please answer for the following questions:

1) Which is the best prop to 3D my plane (13x4, 13x4W, 14x4W, 15x4W)?

2) Best prop size to brake in my new 63S (Wide or Sport prop)?

3) Best plug is OS F?

4) Is Wildcat HELIMIX 15% nitro (this has 18% oil content) OK for braking in AND flying?

5) Do I need to add some synth oil to bring the oil content to 20%, or just run it with 18% oil content (no adding more oil)?

Thanks for your help.

you did not state the size of your aircraft or type. I prefer 13x4w with so low a pitch it needs the wide width to keep the engine from over reving. this gives a lot of tractor power 13x6 is a good prop too for a little more speed less tractor. You will have less problems with 20 nitro and the engines like to run rich. Run one tank on ground to get engine running reliable and right then finish break in in the air to keep from overheating.

Hi!

My plane is Seagull Harrier 3D (46 sized).

Can´t get 20%-30% nitro for the next few months........dealer wouldn´t like to order 30% nitro cans, as they got so big stocks of 10% and 15% nitro cans (30% nitro cans they sold out quickly).

Thanks.
