It will become a dart, a brick, and beleive me, it can bite you.
Look...you can do what you want with modifications, but this was not just some random cheap components thrown in the plane....we are not freakin' Banana Hobbies, who will sell you any junk they can.(that thing is a park flyer at best, people are going to freak when they actually get them, but BH does not have any anyway), but the most effective system for this plane, will still keeping within design parameters. The retracts work great, the handling is great, the structrual strenght is great...add another battery, add more weight, and everything changes. A second battery, for example, is over 25% gross overweight for this airplane.. With foamie EDF models, light weight is the key.
Just sounds like a saleman pitch to me for his stock setup. Do not worry yourself about posting his comments as you did nothing wrong, just reported back what you were told. I do disagree with what he says, my video prooves how well it does fly on my setup at 700 watts with two 3S2200 lipos. Oh well.

Sweet. Mine is going to be a long project. It's getting a full lighting system, retacts and a pair of your wicked 4000 on 4s. I may as well go ballistic as what I really intend for this airframe is to blast up to altitude, do a circuit or two along with a couple of fast flybys and come in for a hot landing. If I get 3-4 minutes of flight time that will be just fine. If I want longer flights, I can pull one of the other dozen jets and play to my heart's content. This one is going to look the part, make a bit of noise and haul buttski during a few short flybys. This is for foamy EDF shock factor, nothing more.

I have a few things I am going to check. I may have a bad lipo which is what I am suspecting. But I plan on checking the battery connections on my Y harness as well. I do not think it would be a rotor issue as I run the lipos on a Y harness, so the motors see the two lipos as one big battery, not two seperate batteries as I do not feed each fan seperately. So the imbalance has to come between the lipos and the ESC connection.

You got it Don. The afterburner lights and strobes will really make this bird complete. Maybe not 100% scale, but the end result should be "wow".

The same thing happened on my twin 75mm F-22. I ended up having a faulty solder joint in one of the connectors that was intermittant. Sometimes it made contact, other times it would cut out. It took a bit to trace it as it never seemed to act up while I was searching.

Thought were running each seperate,, oh well... guess I am striking out good today.......
Joe.. keep us informed, sounds good. I want one but I have bought so many lately that my budget is getting overspent.
I am still playing with my griphen form starmax with dons 4800 motor. Love the sound of that baby .. I took off the wheels and hand launch.Also extended the rudder about 1 inch. Going to try some knife edges.
I love the way this plane can just hover to the ground. Freaks people out.

Easytiger(Curtis) was banned a long time ago from this forum(RCG) for his penchant for arguing. I know he was at Wattflyer forum but I do not know if had changed his modus operandi.

Would a twin sf fan setup on 4s1p be lighter, 3300mah battery from say a f-16 set up?
Better yet witch fan is better?

Twin SF on 4S should be better than what I have, I am at 700 watts, the setup you mention will be 950 or so.

I really happen to like the SF/Wattage fans with the 6 blade impeller clipped to 3 blades.

For the price they are a good little fan. $13 get you a pair of them. I think they are a great bang for the buck.
