I need some opinions for my next Sport Aerobatic airplane. I am in the US and am thinking of getting a Hanger 9 Tiger 30cc ARF from Tower Hobbies. I want to put a FT-200 on it. 90 inch wingspan and 16-18 lb. Probably a little more with a FT-200. Will the FT-200 have enough power for sport aerobatics? Is there a better ARF choice?

How is muffler pressure factored in?

I agree. As long as Laser engines are high quality, I don't see any reason for them to less expensive than Saito or OS. I'm sure that the 70 and 80 will still sell at a "profitable" price. Those smaller Laser engines are perfect for sport flyers and probably get more flight time than the big ones.

Any news on gasoline engines. That market is really taking off in the US. That would be a way to really increase the company's income. There are also complaints about the web store. Put in a shopping cart system would also help sales. Just trying to help keep the company financially healthy for years to come.

A 50 to 60cc Radial is something that I would be interested in. Looking forward to seeing the prototype test runs.

Radial Questions: 1. What type of intake and exhaust will they have. It would easier to install and tune if it had an intake manifold and a single carb. Exhaust rings are very popular, that's what I like. 2. What size for the first prototype? Will you have a prototype by the end of the year?

lithium-ion battery ?

I think that the type and quality of the oil is as important as the amount. The modern synthetic oils are much better than the oils of 40 years ago. If you ask the local experts about fuel, also ask what type and brand of oil. I really like KL-198, that's all I use.

Today I did more fuel testing with my Saito 56. Because of Jon's recommendation I increased the Oil and decreased the nitro. Old mix was 12/12, new mix is 9% nitro and 15% oil. I could feel the difference in flight (less power). Engine runs well and power is plenty for my 4-star 40 so that will be my standard mix for that engine, and probably all my Saito engines.
-
Thanks, That's the information I was looking for. I will add a add oil and reduce nitro before I go flying.

Today I tried some lower oil fuel in my well used Saito 56. One thing I noticed was more power. My old fuel was 15% nitro and 17% oil. My new mix was 12/12. Next time out I will try less nitro. The Saito 56 has way more power than I need in my old 4-star 40. .

What are the main causes of valve spring failure? If I need to decrease the RPM a little, I can do that.
-
Any comparisons of synthetic oils? I have been using KL-198 this year. Is that OK or is there something better?
-
Was that all synthetic oil?
-
Looking for advice on fuel for a Saito 82b. I have been running on a commercial 4-stroke mix with 15% nitro and 17% all synthetic oil. I would like to try lower oil but not sure how low I should go. For this engine I have tried various nitro mixes (all with 17% oil). Anything below 10% does not run well. My next batch will probably have 12% nitro. How much oil should I use? .

Any news on the FT-310? .
