Need help with upgrades on my new Dragonfly

Just purchased a dragonfly from microrcs. It is my first heli and with such a cheap price i think its a good option.

Wondering for the cheapest yet most effective upgrades what should i get besides the whole battery thing(which im going to do)

i came across this post during searching:
http://www.rcgroups.com/forums/showt...ight=Dragonfly

and seems like a custom engine upgrade and looks interesing.

also i read something about a DD tail motor i need a link on where to find that if possible.

thanks guys, ben

upgrades

i too just got my heli too , i got the aerohawk and love it. ive been doing some resaerch and i think most popular and effective upgrades ive been contemplating is 7.4v 1200 lithium batteries and charger. motor upgrade( i ordered that same motor two days ago from same tread). pinion to 8 tooth is suposed to be easier on motor load. trim the blades to get more head speed for more response trim from 3mm at root to 2mm at end of blade. and 2 mm off the end of blade to make it shorter. dd tail rotor is suposed to be tons better from what i hear but im holding off on that one for the moment.

and that should have us busy for a while. but continue flying between upgrades to rate progress and good luck.

From what I've read in this forum, the following are recommended upgrades beside battery & motor:

1) Swashplate with ball mod - $10.00

2) Shaft collar - $8.00

3) Direct drive tail motor - $11.00

Hope this help.

Those three for sure, dont forget heat sinks for both motors, they will pay for themselves in an hour of flying.
Trimming your main blades or using these http://www.rcgroups.com/forums/showt...&pagenumber=11 will help your heli fly better too.

Heatsinks should be available anywhere that sells GWS, and that is almost everywhere. Do not under estimate their value, they are essential.
Yes, I make the blades. I will send you a PM with order info.

Sigh. I paid full price a few days ago. And, mine arrived with one of the ball arms broken off. Haven't tried it in the 'bird yet, but it looks to be a direct replacement from very, very similar molds.

I don't know what's wrong with the US/Canada border with regards to shipping, but in the past month or so I've sent and received several packages from "up there" and the delivery times keep... getting... looongerrrrr...

Ben,

I struggled with my Dragonfly for 4 months. I just couldn't learn to hover it, it reacted sluggishly to cyclic inputs, and even with reduced throws I would always over control and crash.

But then a Dragonfly "expert" over here told me to do two things. Cut the TE of the blades down by 3mm at the root and 2mm at the tips, plus make a head stiffener from Dubro ball links. Doing these two simple and cheap mods transformed the control response of the model and instantly I could hover!! Now, two weeks later I am just able to fly slow circuits around myself. But the bad thing is that I am getting seriously addicted to this heli thing.

Graham.

Can you elaborate for a newbie what exactly to do on these 2 mods:

Cut the TE of the blades down by 3mm at the root and 2mm at the tips, plus make a head stiffener from Dubro ball links.
