Been put off the Gripen by the post about it's alleged lack of power. I just want to fly it scale like I am not that interested in tearing up the sky but if it is underpowered I might give it a miss, which is a shame because I have always like this model. I am not going to buy a model then buy a different motor to put in it. I am sure Alpha knows more then most about what motor wlll suit this model and he has been right on all the other Freewing models I own. Just need someone to reassure me this Gripen is worth buying and not a white elephant

The earlier comments about these being underpowered, you could deduce that prior to buying the model. I bought the PNP because a.) I'm a terrible modeler who gets frustrated easily and b.) I wanted to try the new generation 1920kv motor. But buying the ARF and swapping in a new EDF Motion sometimes makes a bit of work because of the short shroud on their fan, plus they don't sell the 5mm adapter separately so you can re-use the stock fan without buying their motor. That's an annoyance, but if you like the plane buy it.
I'm guessing they didn't go 90mm because of the lack of air for the fan.

I’ll be flying it stock. I will say though after getting it out an assembled I was shocked at the size for a 80mm.
m sure with the inlets and Chester hole there is plenty of inlet air available for a 90.
I’ll see how she flies first though on the 80 before I plan any type of changeout.

I have the Gripen in the box, waiting for TV-unit and my painting-skills to improve since it needs a Swedish livery. I have the Tigermeet M2000 and just love the option to power out of bad judgement at low altitude and I would really like the Gripen to be able to do the same and to accelerate in the vertical.
There seem to be a lot of knowledge and experience in this thread, so what do you suggest? Is it even possible? If 8S, any specific combos you think are good? Is 90mm an option or is the inlet or outlet area not large enough? Any ideas are welcome, except turbine, I'm not there yet

They just want more based on their flying demands. I bought the ARF PLUS to put in the FMS unit. I have no idea whether the stock system lacks power or not. I just wanted the most out of the plane that I could justify spending. You need to watch the videos of the stock unit and decide for yourself rather than taking for gospel what a few others have said, not knowing what they demand from their products.
I had a bunch more flights today with the CG at 135mm and like it there.
The landings are just incredibly easy. I have mine set up with a lot of down canard after landing to look like the real ones' use of canards as air brakes.

Originally posted by kallend View PostI'd suggest it's not so much underpowered as overweight.
I mean, the jet flies fine. Similar size and weight as the older Eurofighter but with an 80mm EDF instead of 90mm.
I don't feel like 'weight' is hindering its flight performance or capabilities much, but having such a low T/W ratio does really impair the jet to an extent.
On the other hand, a jet like the high perf. F-18 is perfectly fine in terms of power but is too heavy, and can feel the extra weight negatively affecting the jet in some regards.
My 2 cents. :)

Another video with this setup has just been posted on YT, look for “mwt- Icarus the 2nd”. I don’t want to steal his video, hence no link....

My Mig-21 on 6S with the FMS 2100kv fan will do about 200m climbs before stalling, so for me that'd be a good reference point.
