 I'm afraid I'm not familiar with this particular kit. However if it's 55"+
 I would look at the 70 Surpass as a minimum.. The 48 is a nice engine, I
 used one in a Coverite Jeep. It pushed it along at a nice scale speed....

 Most warbirds had a power to weight ratio of around .2hp /lb (ish). So to 
 get a like performance if you plane is 5-6lbs you need to be looking at 
 1-1.2hp ie the 70 surpass....

  I wouldn't put in a 48, or for that matter a 45 two stroke. You'll be  
  dissapointed with the ( lack of ) performance......


 As an aside I went to afullsize  airshow last summer, turned out to be 
 all WW2 planes.. The opening display was 5 P51ds flying flat out, low level
 along the runway.. Quite some site.. I fell in love with Mustangs and had
 to build one...

 I recently I had a trip to the San Francisco, so I took the oppertunity 
 to visit a model shop or two cos stuff is so much cheaper on your side 
 of the pond.... I went to Sheldon's in San Jose.. What an eye opener, so 
 much stuff.. I was like a kid in a candy store.. Amongst the $500 worth
 of bits I left with was a Pica P51 kit, the 1/6 scale one cos I have a engine
 for it... I've had all the bits out of the box several time, looks like
 really good quality.... Has anyone built/flown one of these?

cheers
