snatch-it

guys,

I have a hobbyking fiberglass 70mm viper jet,
question is, if I was to use it on the slope as a pss model I will be taking out all the unessesary bits and bobs, but, what you do with the air intakes??
do you blank them off or leave them open??

regards

Why take anything out? Just toss it off the cliff and don't turn the motor on. Or are you trying to save weight?

was thinking on saving weight so that it should fly better in lighter winds.
just unsure what to do about the intakes, would it cause drag if they were left open??

Yes they will cause drag. Cover them with clear packing tape.

thanks.
will give it a try. should look and go quite well in the winds we are having at the moment.!!

I cut some foam insets and pushed them in the inlet ducts on my Top Gun Viper jet, but the only PSS flight I had wasn't a raging success, but the lift wasn't that strong and I chickened out rather than risk a long walk.

that's just the thing. could be one of them "I will pick it up on the way down" moments!!!!!!
think it will need a good lift to fly well.

I did this once with a foam propeller jet called an Electrajet from e-flite. Did not work very well. I think the problem was that I got it too light and could not maintain enough speed to generate enough lift on the wing profile.

I ended up putting the motor back in. It still did not slope very well but it was better with the weight back to its normal flying weight. You can see where the speed 400 fit between the tails.

After that I just took any "power" planes that I wanted to fly on the slope and just tossed them off. Either they flew well or they didn't and I always had the motor to recover if things went badly.

I slope a variety of gliders, e-gliders and have sloped a few electric planes too.
