How effective are the flaps?

Nice, Saito 72 is a perfect choice. I had a Avistar Elite a few years back. Nice flying airplane, I really liked the flaps. .

Last couple of years I have been trying the new Futaba universal series (300, 301, 400). I like the S-U400 Universal Servo better that the others. Well worth the extra price. I have two sets that have been flying for over a year. These are now my go-to servo. .

6V eneloops for the past 15 years. They last a very long time and are low self-discharge. Use to buy them but lately I have been making packs myself. Get the white ones not the black ones. Old and new Futaba radios. Futaba and Hitec servos.

Any news on the website?

I mix fuel and use 15% high quality synthetic oil and 10% nitro. The key is high quality oil. I never use any Castor oil in my 4-stroke engines. .

After much experimenting this works best for me. Much quicker than a crock pot with excellent results.

APC 12.5x6 is what I like best for sport aerobatics. A 13x6 is good. Best to do some flight testing. I did fly a 12x6 for a while. If you want faster a 12x8 will work. .

I was reading that high PH cleans better. What PH range will turn aluminum gray?

I have an ultrasonic cleaner. Will that do any good? What fluid should I try?

Any way to make this crankcase look like new?

Is there something wrong with this piston or just the way it was manufactured?

I need to make a decision about changing the ring. I have spare rings. It does have fairly good compression. Is it a good idea to replace the ring or should I use the old one until the performance starts to drop off?

I like that idea. I will get a bearing and see how it goes. Another question: this is more about the rear bearing. Stainless steel vs standard bearing steel. Stainless is softer but should not corrode as easily. What were the OEM bearings?

I have a couple of old K&B .61s that I will be rebuilding this winter. I have a question about the front bearing. Should I get a shielded bearing or a sealed bearing.
