What is your objective?

If you are flying ALES contests, then you prop up so, at a minimum, you can hit 200 meters in 30 seconds.

If you are just sport flying then a lesser climb is probably better.

If you are flying LMR events, you NEED a faster climb than the stock motor can provide.

For the most part, even at ALES power levels, maybe 130 watts/pouind, the weight of the motor/ESC is comparable to the lead you would put in to balance the plane. The biggest variable is the flight battery. If we keep the weight low then a larger motor or prop will not likely hurt your glide performance to any significant degree.

yep. The twin I fly in my avatar takes a pair of 1300s so I have about 18 1300s of various manufacturers, mostly GensAce. I'm not a big fan of charging at the field so I buy enough batteries so I don't have to. HobbyPartz has been a good source since I get them in less than a week and they have good sales. 25C seems to be $9-10 and free shipping on orders over $50 (I never have trouble doing that)

Oh, I play with those numbers myself, for my ALES glider, my watt meter is never too far, I like to get as much as I can out of my system. Having the newer 45-90C lipos makes life easier also.

For me the best compromise is to stick to the stock power setup. I have zero interest in having a glider that goes up like an F-16 but has to come down for a pitstop after 2 climbs.

I have the Radian, not the Pro. I have upgraded the Prop to meet ALES standards. I use 1500 25C 3 cell packs.

I get about 3.5minutes of full throttle time. That is usually enough to give me about an hour of air time per pack.

What's the increase in amps over stock? I bet not massive.

Ya, this hobby can become a bottomless pit when it comes to money. But a guy has just gotta have stuff to play with and there are worse things that it could be spent on.
Flying the twin requires two packs per flight. 6 rounds of combat means 12 packs. I tend to buy them in 6-packs, 6 GensAce, 6 sky LiPos and 6 nanotechs. The GensAce and Nanotechs are pretty equivalent. I have 3 chargers and do most of my charging at 1C. I also have 20-ish 500mah packs for the indoor stuff. We have a 4 hour session during the winter each week and I just fly them all down and then keep feeding the chargers while I'm in my workshop the following day. I also have several planes that are happy with the 1300mah packs so I don't have to have 14 different capacities to take to the field

I have seen other videos of people shooting down RC planes for fun, and in most cases the pilots are also having fun by flying in an evasive manner. Also, they are usually using a collection of old parts and pink styrofoam to make up something that just flies. It's all good fun.

In this case, the shooters were beginners, and so the pilot's job was to float it in and make it easy to hit. Given that, why would they use a new and relatively expensive 6-servo airplane?
