    Dave, don't stress yet. Your engine, if it weighs 6.35 oz, is only a third of an ounce more than a PAW 249 (which I think the model was designed for). The amount of tail weight needed to compensate...

    Hi Greg, a scaled-up Stiletto sounds like a really nice idea - maybe about 38-40" span? Alternatively, you could look at Geoff Pentland's Kookaburra designs. I've found his Ki-61 (as kitted by...

    Chris, where is '0.30hp' quoted? I didn't think Dave was going to make any performance claims for it, and I'm surprised if he's gone for something as low as 0.3. From what we've consistently seen,...

    Maybe the lack of nippyness was simply a function of turning an 11x6 at about 9000 rpm, and a bigger model would've been no slower? I found an 11x6 or 12x6 on a PAW 35 would power a 48 oz, 540 sq.in...

    Hi Ehsan, I'm sure the model will fly very well. At 44" what you've got would go well with about a .25. For a .36 I'd go even bigger - maybe 52" or 54" span.

    Bear in mind that you don't have a lot of width to work with (assuming it's not a profile) compared with the length of the tank. Might get a bit ugly, say in the latter part of the square 8, with the...

    If the 11x5 doesn't work out (I never tried one with a PAW), they go fine with an 11x7 or 12x6. Oh, and you've got to ignore all the people who are going to ask if it isn't too nose-heavy - I reckon...

    Just to give you an idea, this is the 'Ee-zee 1' I've built with my son. It's no oil painting, but I'd say it ticks the 'somewhat rugged' box. The tank is 1 1/3 oz, and the engine is mounted as far...

    Hi Dave, going back to what you said earlier, it sounds as if this model might have a fair chance of being pranged a bit - in which case it really needs to be good and strong. If you go with a...

    My fuel costs me about $17 a litre. About as much as it costs to drive my car 130 km, or for a couple of decent hamburgers, or for about a third of a carton of beer. Guess what gives the most...

    Ray, I assume the article's just on the site because Christian Traders currently have the MVVS dealership for Australia - I wouldn't expect it to end up as a replacement for MEN.

    Flying CL, I'd regard a 7x4 as too small for something like an Enya 15. Most glow 15s, I'd be looking at something like an 8x4. The Enya 15s, though, are quite torquey compared with their...
