That looked really good Maxman, and it sounds great too. I don't have a Habu (building an eflite F-4 now) but I can see that it doesn't slow down at all! Looks like a great flier. Good thing you have that awesome looong runway!

Nice Maxman! The sound of your jet is awesome. Nice job on the maiden, but it will slow down much more than that for landing..looks like you came in HOT!! Good thing you have a huge place to fly. You'll get the hang of it, the more you fly it!!

Yep to the above Maxman, on your next flight you might try extending your final approach by 150-200 meters, so that you can get the plane stabilized and slowed down for landing. A nice nose-high, power-on (but just a little bit of power) approach works great. Nice runway!

JG makes some great points, a longer, flatter approach is always best to bleed the speed. Some of my best landings in the Habu have resulted in a 100 foot roll out or less. Its very satisfying when I can do that.

JG, did you get the Habu32 you bought on RCG flying yet?

Heck no! Been too busy blasting around in my Sundowner 50, beater foamy 5s Habu, and FJ Ultra. I think this weekend I'll get it going. Just bought a few extra batts off here, and I've got the extra long weekend. Should be some fast fun. Hopefully it'll be windy and no one will show up at the flying field

Maxmann,

I agree wtih your strategy to conquer the Habu first. I have both planes ... the F-4 really looks neat both on the air and on the ground (the Phantom has always been one of my favorite fighters), but it flies like a scale plane. It's not nearly as precise and smooth as the Habu. It's also harder to see in the sky and harder to land nicely (IMHO).

Actually, negative expo on JR will make it more sensitive around neutral. Dial in some positive if you want to soften it up.

I think I got them backwards, I would have to go check on my Futaba to make sure, but thanks for clarifying.

Hey guys seeing as how I'm new to the EDF world and I'd love to pull the trigger on one of these, I have a quick question about altitude. I fly at/or around 5000' and I imagine that there is a significant performance drop compared to sea level flying. To keep performance would I need to upgrade the motor, or is it something I could take care of with batteries (i.e. 7s/8s instead of 6s?). Thanks!

I live at 5300 feet, still works great. Stock will fly it fine at this elevation , but you can add a cell to 7s for greater power and faster takeoff. Lots have run the stock motor on 7s and it lasts just fine. You could add a heatsink to help on 7s

Or you could go jetfan 80 with 2080kv arc motor or het motor , stay on 6s , get better performance and speed.

Hope this helps.

I'm at 4800' and I second what 420Flyboy said. If you are building new, it's an opportunity for an upgraded bird if your budget allows. I would consider 8s, 10s, or even 12s systems. My latest is an 11s system on a Jetfan.

Nice , on the 11s. Thinking of building a 12s one , I can fit 4000mah 6s packs in to make 12s , use jetfan 80 and het 700-68-1400kv , ice120hv and tams struts

I'm thinking this motor on 12s
http://www.highendrc.com/index_eprod...roducts_id=316
650-68-1340kv

Maybe around 100amps and 4500 watts, that should get it going

I like the 700-68-1400kv better on 12s than the 650-68-1340kv on a Jetfan just because it's 39mm rather than 36mm and I think that extra diameter size will help with heat and because it's heavier it will help with balancing the 2 4000s. But on the other hand....lighter is better when going for top end speed.... so the 650 with 3300's would make for short but fast flights!
