Status: offline 		hey everyone

I recently got a dragonfly and am getting quite good with it. The only negative thing is that the stock batteries die with 5 minutes of flying. i have ready li-polys are the way to go. My question is, what exactly i would need to buy to make li-polys work in my dragonfly? I am still quite new to this so any suggestions on what to get, and where to get it would be appreciated.

thanks

The best LiPoly for the Feda/DragonFly/Hummingbird , is currently the E-tec 1200mAh two cell packs. You should be able to fly about 15 to 20 minutes. You will also need a LiPoly charger. The main problem now is going to be finding somewhere that has the battery packs and chargers in stock. Everywhere I check seems to be out of stock. To get the shortest charging times you need a charger that can charge at the capacity of the pack, so for the E-tec 1200mAh, you will want a charger with a 1200mA setting. I don't have any recommendation for the charger, but [url]www.b-p-p.com[/url] seems to have a very good selection of chargers and battery packs, if only they could keep them in stock. For most of the chargers, you will also need a DC wall transformer that will supply about 12 to 15 volts at around 1.5 amps.

Jeff

ps. The LiPoly packs are so light that you will have to move them very far forward to balance the heli.

Status: offline 		with regards to lipos - you can't use the same number of cells as lipos cells are a much higher voltage than Ni-MH cells. 1 ni-mh cell - 1.2v ..... 1 li-po cell = 4v ish.

Trust me, a FP heli needs a 2 cell lipo. I've tried it. Tonnes of performance and 20 minutes flight times.

Status: offline 		i was very surprised to find out how easy my dragonfly was to fly. i fly it in my 2 car garage and can take off and land on small boxes that i scatter around the garage floor. i have taken it outside a couple of times now( in zero wind) with great results. another gripe that i have is the motors burning out so quickly. i have been flying about 2 months and i am on my third main and second tail motors(i have a stockpile of replacements though). i took off the plastic tubing from the main shaft(helihobby mod) and also added the blue swash plate(very expensive) from hellihobby. this thing flys like a dream now, but for ONLY FIVE MINUTES! hopefully lipolys will fix that though.

Status: offline 		I bought my dragonfly from [URL=http://www.rc-expert.com]www.rc-expert.com[/URL] . They have been pretty helpful via email for support, and shipping was fast, even though it comes from Hong Kong. They seem to carry all the dragonfly stock parts.

I've had mine for about a month, and I think I damaged the batteries by overcharging. I left them both plugged in overnight on accident and now the main rotor power has gone down the tubes. It will only lift about 3 inches off the ground and that's when the batts are fresh. Has anyone seen this before, before I order a new set of batteries? Could there be another problem?

Most likely you have damaged your batteries. We sell the batteries for US$ 13.00/piece, so not a big investment you have to do to get your heli up again. Wordwide shipping, like jefs555 said, is US$ 5,00.

Status: offline 		riderclimber,
[URL=http://www.heli-world.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=H&Product_Code=CNE050]Century Heli[/URL] has the batteries for $11.95 and I'm sure [URL=http://www.helihobby.com/html/hummingbird_helicopter.html]Heli-Hoby[/URL] has them too. Both are quite close to you and should be faster than ordering off-shore. 1200 mAh Li-Poly batteries make a great upgrade (20 minutes flying on 1 charge).

An easy test for a cooked battery would be to 1) note how high or well the heli flies when the batteries are fresh off of the charger. Then 2) recharge the batteries, take them off of the charger when done and let them sit for a day or so. Try flying the heli now. Is the performance substantially worse? If so, it sounds like a shorted cell in the pack. You can do the same test using a volt meter (VOM, DVM etc.) if you have that available.

The stock motors have be known to be week points. Many people have found big performance gains by changing to GWS370 or Speed 300's and a 9-tooth pinion. Heli-Hobby should have those...

Status: offline 		For the amount of time I've had the Dragonfly, I'm already feeling the urge for something a little larger/more powerful. Is it worth putting money into the Dragonfly for upgrades or would money be better spent on a different
