Default Picking a glider

so My Bird of time bit the dust. A winch start guy was going to show me how to fly. He launched the BOT with a hard toss and a lot of up angle. Since the Bot had an upthrust issue, It tried to loop stalled and crashed. Totally not his fault. I guess I thought he would automatically throw it straight out.

anyway. I am replacing it.
I want to buy something designed for a motor and with ailerons

I am down to 3 choices in my price range.

https://www.espritmodel.com/champion-28e-arf.aspx
and
http://www.skipmillermodels.com/Lega...m_p/legacy.htm
t

the Skip Miller is I think a renamed gliderman

I believe that the gliderman is basically a bird of time with a motor mount pre built in and both servos in the rear instead of just the one. The only reason I am even considering it is because of the larger wing area and lower wing loading.

I have to say though I loved my bot. I found it to be pretty lethargic and not much fun to fly. It was beautiful.. and of course there was the terrifying part about launching it with the motor wanting to make it loop.. (My fault and it wouldn't be that way this time.)

Anyway. I am most attracted to the. elipsoid evo I like the idea the the horiz stab is removable and that it can easily be shimmed to change Decalage.

My problem

am I going to hate the change in Wing loading after having been used to the BOT.. I will say that their specs for wing loading were as a pure glider and the plane did gain some weight during electrification. so Hell it might have already been around 12 oz/IN

I also need to buy today or tomorrow because I am taking a trip to go fly with my brother and only have a couple of weeks to pull this together.

opinions please ASAP

Sorry to hear about your loss. I had a fellow member take my Carbon Z CUB up this weekend without asking, or doing a preflight check, and stuffed it into the ground. Not a great day.

Anyway, I don't know about all the specs on each, so take my comments with a grain of salt. I think the Skip Miller one looks the best. I like the ones that look a bit different, and that fits the bill. If I'm not mistaken, it's similar to the BOP as well.

Good luck either way. A "real" glider is on my wish list after a DLG, I have a Radian now but want to step up to something nicer.

Those three models really look nice.

I flew a lot of different gliders or sailplanes back in the mid 1980's, up to a pair of Craftaire Viking polyhedral 10 foot wingspan models. After getting tired of pulling my winch parachute out of the trees, five of those sailplanes were electrified. Never went back to winches.

Those electric power systems got the 10 foot models far higher than a winch could ever do. Add to that, the same power system could haul those models up several times.

That was back in the days of Astroflight Geared 40 Cobalt Brush type motors, and an 18 Cell Nicad battery pack. That power system could haul the 112 ounce sailplane up at 45 degrees, and just keep on going. Now days, you can double the watts capability, with 1/2 the total over all weight.

As for modifying those models, I just cut off the nose of the sailplane, and spliced in a front end for electric power. It took a bit of work, but those two Viking models had a number of two hour plus flights on them. And, that was in South East Wisconsin. It was interesting. First, one of those Viking sailplanes was electrified. That model completely out flew the other standard winch launched model, so the second Viking was electrified shortly after. As for weight, it was reasonable, since a lot of lead shot had to be removed from the nose of the sailplane. The addition of the motor and battery pack was only a half pound or so of added weight.

Hi Everyone Thanks for your comments.

I have decided on this.
https://www.espritmodel.com/elipsoid-evo-28e-arf.aspx
I have had a bad year flying and have already destroyed 2 airplanes.

The BOT was a disaster waiting to happen the way the thing tried to loop when you launched it. Still I made a stupid mistake and it is pretty much destroyed. I Believe I could put it together, but it would no longer be the quality I wanted so

Wish me luck on the elipsoid. If I crash this one... I am making myself permanently limited to foam

That is a nice looking Glider and the price seems very reasonable.
No shame in foam, but the wood definitely flies better. I have been flying a Phoenix 2000 for some time on and off. The only thing I liked was the plastic fuselage. Very tough stuff.
So I made a balsa wing for it and did away with the ailerons and flaps and it flies twice as good as it did with the foam wing. It is now 2.3 meters.

He helped me retrieve it, then said, wow...sorry, dunno what happened. Then he left within 10 minutes. Oh, and he has the same one too. If it was reversed, I would have handed over my complete plane, battery included and said, it's yours (assuming it was in good condition).

I've started maidening some planes for a few of the members in my club. I consider it an honor, and treat their planes as if they were mine of course. Even when asked,before I take off I say, are you sure this is what you want? Knock on wood they have all come back fine. If I had the sticks over to someone in my club, it's on me. Unless they do something intentionally, my thought is that I will take the loss of the plane if it crashes for any other reason, and that's because I handed it over. Worse yet, it was only the third flight!

Turns out I need about $80.00 worth of parts, and a few hours of foam repair, paint, and covering (I did not go with the stock color scheme). It would be nice if there is an offer on their part to pay, but you can't make people do the right thing, just hope.

Did you ask him? I would say - hey man - were is my replacement plane? You broke mine, didn't ask for your help, or offer you a flight on my plane!!! "You owe me a plane".

Not cool but you are right - you can't make them do the right thing.

If you don't ask and let him know he owes you a plane - you need to establish that fact (even though you should not have to do that...)

This plane is awesome. I will never miss the BOT

Not the website calls for 68 oz flying weight. Mine weighed 52 oz which makes its loading 9.4 oz/sq ft

it will float but a 10 mile an hour wind only means a little down trim.

It will turn in a very short radius without falling.... Like maybe 26 ft or so.. (this is probably an exaggeration but very tight..


Wow Love it!
