Prop stall eh, well if it has a name, I can blame it.

Lol, me and my friends have a 'little book of excuses', it covers a variety of situations. In fact, I've never seen something happen that wasn't covered by that book, amazing TBH.

Looks like a MPX 6 pin connector http://www.electricwingman.com/multi...onnectors.aspx

Personally I'd desolder it and use something else, easiest thing would be to change it to whatever your batteries have on, XT60's etc.

Maidened my dog yesterday but it didn't go as well as I had hoped. Got her launched easy enough then one of my aileron servos developed a random twitch. She would fly nice for a bit then mad wing wobble. Got her down for a safe landing, but I need to replace that servo.

Read up on glassing and now got both wbpu and epoxy on the way. Tempting to use the epoxy with glassfibercloth for the front fuselage, front of wings and underneath fuselage. Then maybe wbpu for rest if needed.. Any experience on using both on the same plane? I want a sturdy plane, but I will be careful with adding too much weight.

Last time i did a plane i bought silk in a shop and used some RC lacker bought online. i cut the silk in squares and made a patchwork on the plane. Looked really cool like pieces of metal plates. As long as they overlap i think the strength will not be in danger.. and easier than fitting a large piece of cloth?

What u guys think?

I use TH DMG65 digital metal gear servos. I get them from Twisted Hobbies and have used them with good success on my TH 3D planes.

Hey guys.

I thought I could post about my setup which is a bit different from usual .

I am using this NTM 35-36-1800 motor on my Dog with a cheapo 70A ESC:

http://www.hobbyking.com/hobbyking/s...00Kv_875w.html

with a Turnigy 4S-2200-40C on an APC 7x7sport prop, I get as static results

62,2A for 888 W at 14.3V

The plane flys really beautifully and is pretty fast . I don't know the speed but it feels that it could almost compare with my 1100W Funjet , at least during the first passes with full loaded battery .
Motor comes down perfectly cold but it is still freezing a bit outside

I first flew my dog on a 115g -1100KV motor on 4 cells with a 9x7.5 prop .
I thought it was fast and I liked the awesome vertical pull with a 9 inches prop .

For sure I have lost a lot of that thrust with a 7 inches prop and I now need to launch at full throttle , but man, it is really fast . Not sure but if you wanna stay cheap on the motor , this 1800kV motor could be the best one can find .

There is one guy claiming 140mph on a H-King review with same motor on 4 cells and a 7x8 prop .
I think it's a bit exaggerated and shall be more in the 120mph range !

I don't know what you think but I can't say enough good things about thoses NTM motors .

motor-plane performance


I have my Turn-3025-1500 on board at the moment. This motor is rated for about 69 amps. The 8x8e was running at 98 amps an 1350 watts...so I backed down to 8x6e and still had mid-90 for amps..the plane is over-proped

So today i tried a 7-5e but i didn't measure it...however the plane was a real no performer in the air...no top end or speed available with topped off 4s 2600amp batt...went back to 8x6e for speed...I need a new prop for this motor any one have a good suggestion...8-4e maybe.....
