Good to see ya in here Cobra! To be honest they fly VERY similar. The Phenom is obviously better looking but take longer to build than a Whip (still a quick build though). I flew them pretty much back to back and I know Vic said the Phenom was faster but I have different engine combo's in each so that is not a good measure

The Phenom would be capable of higher speeds due to the cowling, and covered up linkages...I will probably end up getting another one to put a FIRE in-

Oakdale put a LOT of thought into making a slick delta...I am emotionally attached to the Whip's but those elevon hinges are scary stiff even on the Whip-X.

I ended up getting another K&B-48 (Ebay- $48 bucks) so it'd be interesting to outfit both with the same engine, prop. fuel, exhaust, etc.

The Whip has the K&B-48 with an Ultrathrust (huge performance gain)

The Phenom has an OS-50SX with a Tower muffler. I did not tach the 2 that particular day but the K&B with the UT is stronger than the SX generally so If Vic swears the Phenom is faster with the less potent engine combo, than that is more evidence...

I really need a digital scale so I can weigh each of them...
