John,

I agree the Kolb fits our needs better, but your description brought back 

memories of the Vampire when it first came out in the early eighties. I 

always thought it would become a lot more popular than it did, but it will 

never match a Kolb for off airport opps.



Denny

PS: I hope they get their crap together and have some success with the 

Vampire as it is a very interesting a bird that has never seemed to fulfill 

its potential.

What engine did they have on it at Lakeland John?

 year.



 The two place flew once during the week.  Was roughly built and 

 underpowered.  Barely got out of 1500 feet of sod.



 I remember when Sadler introduced the single place many years ago.



 I'll stick to my tried and true Kolb.

I don't know.  I was not interested enough in it to inquire.  The two place 

looked really shabby.

Not John, but I'll answer.  They were running some sort of rotary 

engine...dual rotor.  I never saw them fly it...it looked real heavy 

(and rough as John mentioned) and not much wing.  Was one of those 

examples of a company I'd never write a check to.  If they are so short 

of capital that they can't make a decent looking demo plane, I fear for 

getting what I pay for.  That being said, I've always thought the 

Vampire (single place) was a very interesting design.

An example of what you can accomplish with a pusher prop:



This is "laminar magic" certified record holder with a

single boom, pusher engine.  25 hp, 498 lbs gross (including pilot)

126.7 MPH

Note Steve Wittman wingtips

BB



Not much room for camping gear though John.

I think the Vampire had a Rotomax 2 rotor Wankel in it. 110 or 120 horsepower (at) WOT. It was certainly not an airframe i would have taken to an airport, let alone S-n-F.

It had a Rotomax 2 rotor charge-cooled rotary engine, rated at around 

120 hp. They supposedly had a 1 rotor in the single-seat, but it was 

still on the roof of their trailer when I visited.



The guy I talked to knew very little about the engine, & not much more 

about a/c design (he tried to tell me that the 2-seat with 120 HP was 

good for up to a 1000 hp V8 (not a typo) that would 'blow away anything 

else out there'.



The 1 rotor engine might be worthy of consideration for UL type planes; 

it's around 60 hp & should be almost as light as a 2 stroke with the 

same or slightly better fuel burn. I tried talking to the Rotomax 

people, but the only guy in the tent at the time was their gyro pilot. 

All he knew was that the 2 rotor made plenty of power for the 2 seat 

gyro he flew. The engines are descended from the OMC snowmobile/outboard 

rotaries.
