With the Turnigy 35-48-1100 on 4S 2350's and an APC 9 x 7.5, calculated speed is 105 mph. This is on my Composite V-Raptor that I have done 1:10 with a Nelson 40. RTF weight was 3.75 lbs. I flew this against my Brother in a mock up race against a TT Pro 40 powered (AMA#424) Conspirator and it was about 10-15 mph slower than the glow powered. I have tried the 9 x 9, but the prop cavitated and I was against the limit of what the batteries would give.

The next step in the testing was to go to 4S 3300's and try again. Then I was going to try 5S 2650's with the 9 x 6 and 9 x 7.5. I hope to continue that testing this year. I want to build a specific EP Q-500 with an extended nose to allow for the battery to be removed through the front hatch without removing the wing. Plus it would eliminate the need to have that bulky GP aluminum mount I had to use to get the balance right.

EF-1's are the same speed as AMA#424 quickie 500's. 115-120mph. I would say that times on the short course (2mi 475' x 100') would be in the mid to low 1:20's.
