Yes they can. Check Hitec's website for complete specs. Also check www.servocity.com. You can find full specs on Futaba and Hitec Servos. If interested in the HS 5475HB Digitals...they are on sale for $27.99. If anyone knows of a better price...let us know. I hope to have this bird flying in 2 weeks. Here in the north east time is against us as the weather is starting to change . No more week night flying after work. We used to be able to get a last flight in up until about 830.....now sun is down by 7pm So for those of you that really love to fly and live in year round warm climates...consider yourselves very forunate.
