Terry,

Thanks for the suggestion. I am familiar with the EJF Byron conversion but did not choose that method because I already had the E-turbax unit. I was looking for a host plane for the E-Turbax and stumbled across a free partnership project with one of my test pilots so it was a convenient and very low cost find.

The Byron conversion using the Scorpion 4035-630 motor on a 12 LiPo produces about 3600 watts but the E-turbax with the Neu 1527/1.5Y motor on a 12s LiPo produces about 4500 watts. The Neu inrunner motor, at about twice the cost, is much more efficient than the Scorpion outrunner motor.

Skyhawk,

After I read your post, I decided to try the link using MSIE 7 instead of Firefox and it worked fine. They may already be aware of it but I'll let them know their site has issues with the Firefox 3.0.5 browser.

It's good to know that I may be able to buy some parts for the A-4 like a new canopy.

Thanks!
