Hello,

My new Impact arrived yesterday. Now it is decision time I have decide to put an electric setup in it but am unsure which one. I can go for the Hacker setup or the plettenberg setup.

I have two concerns:

1. I may not be able to get the hacker setup under 5kg especially if I am adding weight to strenghten up the tail and fin as discussed in other threads.

2. Plettenberg setup may not have as much power as the hacker.


Other factors:

The plettenberg setup is ment to be quiter

There are no gears in the motor




I am undecided as I have seen alot of people goiung with the plettenberg setup with Impacts as it is a lighter setup. I am afraid I will have to lighten up the impact too much to get it under 5kg with the Hacker setup.



I would be interested in hearing any suggestion or comments about this?


Would also like to hear you comments on:

Plettenberg V's Hacker Motor

Schultz Speed controller v's Hacker Master 90

Emcotec Batteries v's Thunder Power.



Also how are you guys charging in these 10s3p 6000mah at the field and at home from the mains.



I know I am asking alot of question but hope you guys can help me make my mind up.

Thanks for your help,

I added about 3 ounces to the tail of mine including a crutch and the rear formers that CompArf recomended, if that helps.

I havent completed assembly and weighed it but its looking like 10.4 lbs with a YS.

My humble suggestion would be to start by weighing the kit components. Mine were MUCH heavier than the figures posted in other threads, almost 300 g total, at 2780g. I've spent a lot of time and $ lightening things up, and then put some back in the form of extra formers, etc., and now at 2460 airframe only. With the Pletti/Schulze and 2 5S2P Duralites, total is looking to be a tick under 4.5 kg. With the new 10S2P TP 4000, it will be 4.2 kg (!), almost too light...

The Hacker setup is ~300g more, so you're up to 4.8kg, then move up to the TP 6000 5S3P twins and you've got very little room to play with. You can swing a bigger prop, though, giving more thrust to compensate. My decision was driven primarily by sound; I don't like the whine of the gearbox. The Schulze controllers are supposed to be more efficient, but I don't know how correct or relevant that is (still learning!).

Hope this helps!
