Default Love the XPD-What's next?

Once I get the right battery in my XPD, I think I'm gonna be in love.

I'm already looking for the next step. Haven't looked in quite a while but there looks to be quite a bit of new great stuff out there just recently in the EDF jet line (not interested in pusher props at all).

Hobby-Lobby seems to have some REALLY NICE planes with fans for sub-$500. Are they any good? Any opinions from owners? Are there others? I want fast and I'd prefer hand-launched as opposed to catapult necessary but I will consider all options.

Help a brother out! I'm hot on the hunt and I Want the best w/o having to shuck the bucks for a real turbine just yet.

Thanks,
bob

Bob,

Do you like to build? If so, there are some awsome jet plans that can be downloaded for free from parkjet dot com. These are depron jets which will cost you maybe $20 in material to build. Best thing ever since balsa.

Good luck!

Thanks. Some of those look interesting. I'm gonna take a closer look.

For anyone else that may be interested, it's parkjets dot com. The other domain kicks you to a site loaded with one of those "spyware" search engines.

The Miglet looks superb but I would like to go brushless and to do so I may need a bigger battery, wonder how large a battery can the Miglet take. Hmmm ... it does look really nice.

Aren't velocities shown the air flow velocity out of the fan unit? The chart shows efflux speed for stock motor with 3 cell li-po at 72.48mph, but flat and level speed is 56mph. My question is what aircraft speed would you get with an efflux speed of the calculated maximum in the chart of 217.73?

I bought a fan unit and made myself a foamy jet using fan fold foam. I'm using a Ammo 24-45-3790 motor that gives about a pound of thrust at 221W. The plane weighs 15.5 ounces, and at full throttle feels like it will hold itself up. Can't wait to fly it.
