View Full Version : HL Ion...Thoughts?

12-30-2006, 12:05 AM
Hi Guys,

I'm looking for a nice "warmliner" and am considering the HL Ion (with flaps). I can pick up one locally for a great price and was looking for input
on this glider.

I'm not looking for rocket ship performance (either up or down) just a nice balance between a true TD glider and a hotliner that won't let me relax when I want to :)

Any thoughts, recommendations appreciated.

Welcome to Wattflyer!

I think the HL ION would be a good match for you mentioned you are wanting. I have known several people that have had the ION or the Hoot (Known as the Hoot before HL starting distributing it) and they really like it. One friend had it setup as more of a hotliner and was using a Hacker B50-6S motor with 10 GP3300 cells. Another one has theirs setup light with a Cyclone mini elite motor and I think a 3s2p lipo pack.

Both versions were flapped which helped them easily land. Hope this helps.

Hello Harry, Welcome to Wattflyer! I have never seen an Ion, but will make a few general comments, for what they're worth; The Ion was designed by Rudi Freudenthaler, a World-Class F5B/D competitor, builder and designer from Germany. He also designed the RFM Scorpio F5B, Suprise (series) and other FAI models.
He has a line of highly-regarded folding propellers for FAI here; http://www.shredair.com/props.html
The airfoil, the MH 30, is from Martin Hepperle, another Internationally-recognized expert in the field of model aerodynamics.
http://www.mh-aerotools.de/airfoils/index.htm Click on "Pylon Racing", Scroll to "F5D" for more info on the airfoil. This section is also used on the Sprinter Hotliner http://www.reichard.cz/en/_sprinter.htm (http://www.reichard.cz/en/_sprinter.htm) Which, although it is no longer competitive on a World-Class level, is a very good all-around "Hotliner" entry model.
So the model has good "bloodlines" and, especially with Gliders, that is important. It is, at 2 meters wingspan, somewhat bigger and heavier that the typical "Hotliner". The suggested RTF weight of 55 ounces is about 12-16 ounces heavier that a 2 meter "Powered Glider" that is primarily designed for thermal duration. The wing loading (15 ounces per square foot) is also more like a Hotliner than a TD glider. This only means that the model won't "float" on the lightest lift, but I have no doubt it will thermal reasonably well.
So, it seems like a good compromise between a "Rocket" and a "Floater" and appears to have a very clean and aerodynamic airframe.
Models with this type of capability and construction usually cost upwards of $250-$300 (or much more, for the newest ones!) so if you can get one for less, I'd say it's a good deal!

HI Harry.
I fly an Ion with a very modest Jeti 30-3 phasor motor direct drive,a 12 /6 graupner prop,40 amp esc,4350 mah 3s lipo.I absolutely love this plane,with a little help from some thermals,I can get 40-60 mins easy..Dont have it set up as a hot rod,I have others when I want to go fast..No flaps on this model,but I have it set up with flaperons,These allow for slow speed final..
use allot of finesse when touching them down as these aren't the hardiest of airplanes..
