Status: offline 		I just bought and flew a Slinger from Great Planes...it is awesome. I had trouble with the rx, I think it might be too close to the motor. Does this sound like it makes sense?? Also should I solder capacitors on the motor.

Also does anyone know of an easy brushless upgrade with a link. I am flying 3s Kokam.

Thanks,

Joe

Status: offline 		Awesome setup Greg. Nice review and video.

I can't believe how much I like this plane, I only wish I had bought it earlier and saved myself alot of time and money.

Did you glue the wing sections together? Why didn't you use the wing center keel?

I broke off one of the wing tips due to a crash from interferance. I was thinking of velco ing them on...do you think it would work?

Thanks for the reply, I am getting your recomendation for the Kontronic set up.


Joe

ps. (edited) I already have a Himax 2025 brushless setup with a Jeti 18 amp in another plane and was wondering if you think it would be an ok fit for the wing. It looks like it would fit with a little foam shim and wire tie.

I did glue the wings together and found that the extra keel was not needed.

Velcro will work fine for the tips. Use the Industrial Strength Velcro.

The Himax 2025 should work fine. It won't have as much power as the Kontronik 400 but should still beat out the stock Speed 400 by a longshot.

Good luck!

Status: offline 		Hi Jobu. I am trying to go brushless. I have the Jeti 18 and am having trouble picking a motor. I can't seem to get enough info about what type plane they will handle and how well they handle it. What weight plane did you have the Himax 2025 in?

My plane with a brushless motor and lipo's will weigh about 20-21 oz.


Thanks for any help.

Funny you should ask. I just put it in my Great Planes Slinger wing which I think is around 20-22oz. I had to weight the nose 1oz. It is very fast. I don't know why I switched it because it was fine with the stock motor, but it was just sitting there so...

I have put a 2015 which has about 20% less thrust than 2025 in a plane w/ flight weight of 17oz and it was more than plenty.

I have had good luck with them. The hardened drive shaft is tough...I nosed onto asphault and actually broke the alum spinned but the shaft is still straight.

I am still kinda new to this but I would say the 2025 would push-pull any 20-25oz with ease.
I have that same set up with the Jeti18. Its nice no soldering with gold connectors. The Himax is set up like that as well...plug and play, the are well mated.

Status: offline 		Thanks! I don't understand why, but, my Jeti 18 came with NO connectors! The instruction sheet says they are on the ESC. I think I got shafted!

You may have made up my mind for me.

Thanks again

Status: offline 		The connectors are pre-installed on the motor and a set comes with the Himax motor for the speed control.
I found matching connectors at Bishop Products website. www.b-p-p.com
sometimes you may need to lengthen the leads from the motor to the esc and these are very good connectors.

Status: offline 		Use a Himax 2815 3000 it is the best speed 400 replacement that you can get for the money, the best is the Aveox 27/13/3 it is about $30 more but it is about 8mph faster. I have used these setups in the slinger and the zagi and it is a marked improvement over the stock setup.

The slinger will not last long stock with a brushless setup, the best thing to do is strip off the monokote and use strapping and packing tape it does weigh more but it will withstand the G's

For you working class people that can not or choose not to spend the bucks for lipos go to www.maxamps.com and order the 8 cell pack to use with you brushless setup they are cheapest place to get batteries on planet earth, with the aveox motor and the 8 cell pack you will be able to go 90mph+ in level flight, my flying buddies and I got a wedgie to do aprox 118mph

Status: offline 		Greg, I'm going with your setup on my Slinger, after watching the video, I'm grounding my 1/4 scale Laser project for a while, the plane flies awsome!, I just want to know, is there a subtitute prop for the 5.5X4.5, Hobby Lobby is out untill mid November , what other prop adapter would work with this combo. I'm new to electrics, so this will take some time for me to sort out.

Status: offline 		Hey Joe,
Funny with the receipts...I'm in the same boat, hehe.

I just picked up the Kontronic setup that Greg used too. I am balancing the plane right now.

It is a 3.2 mm dia. shaft on the motor, I picked up one of these...

MJ4702 COLLET PROP ADAPTER 3.2MM from www.hobby-lobby.com

If you cut the stock number and paste in the search box on the site...it should come up; otherwise look under prop adapters.

I am still a newbie but I recommend picking up a few wing tips too, I already broke 2 they're kind of brittle.

I think the prop is a 5"X 4.3 but check the writing on the stock prop to be sure. Any prop that size should work.

Also had problems with servos getting loose. And I seem to need alot of weight in the nose to balance wing.
I think that it is due to the lack of weight of the Kokam 11.1/1500mah batteries.

I had a Himax 2025 in the wing and it was insane, 70-80mph. I can't wait to see it now.

Good luck,

Joe
