Here's a video with my Mig on 2S 800mAh. A bit nose heavy perhaps - but I think I'll try to trim the ailerons up a bit more - I really don't think the elevators are effective at all.

Maidened my A10 (finally). Used a hyperion 2S 850mah 25c, all the way forward for the proper cg.

I used the landing gear. I had a little problem with the motors being out of sync. Had to re-set the esc throttle tx 2 times before it worked correctly.

1st flight she needed about 7 clicks of right aileron trim. Using high rates and 25%exp. Fun little flier. I am flying with the bombs, so prolly not as fast as she could be, but still very zippy.

My first landing tore off the radar and front cannon. I'm not even gonna bother to reattach.

I only flew for 3 minutes (new batteries) and came down with 3.93 in each cell left over.

I tried to use smaller batteries but she really needs (at least mine) the weight of the 850's all the way forward.


I also had 2 more flights w/ the F86. 2S 325mah 65c thunderpower. Fun, but I will probably go to 3S soon enough. It always seems on the edge of a stall during turns.

My Mig 29 was going to get flown too, but I broke a control horn during the pre-flight checks. I was glad it happened on the ground. Anyone have an idea where to get some micro-control horns and hardware????

Wave that sounds good hopefully getting mine in a couple weeks. I have several 500 mah batteries so hopefully they balance out. Got some 850 3s batteries, has anyone tried 3s in the A-10?

3s will work w/ the motors, but not the stock esc's. The escs will fry.

The motor really is so cool that it really isn't worth the effort...For grins and giggles I'll break out the hand held IR thermometer and check it...Like all of the cheap IR thermometers it is permanently set for an emissivity setting of 98---Which is what human skin is...If I don't get any reflectivity then I may be able to get a somewhat accurate readying...I'm thinking of coloring the can with a stripe of black from a Sharpie...Since this is one of the cheapo IR thermometers just like almost everyone has (Isn't emissivity adjustable) the readings will be ballpark at best....(+ or minus 10 degrees is HUGE!!!) That's why I don't hold much faith in the readings posted here on RCG as it really takes training with one of these to get accurate readings...

I'll see what I can come up with...

Brian, nice video!

Floats pretty slow even with that 800mah in it. I just ordered a couple 500mah 2s for mine.

Will be interesting to see what more aileron throw will do.
I'm going to also want to play with mine and see what works best. also try full tailerons and for sure thrust vectoring.

Guys, I finally received my hawk kit from HK.
As I don't have the manual, could someone please post the position of the CG?

Many thanks!

hi, does anyone know if this ESC can handle the rpm of motor in the 35mm bae hawk on a 3s?

i bought an 18A esc as i can use it for another project and as its not much bigger and only a few grams heavier i thought it would be fine but it didnt cross my mind if the ESC could handle the crazy RPM of the "9000kv" (cant be right) motor on a 3s or not.

the plush 10A esc's which i read work well are available on ebay in my country so i will just buy one of those if anyone knows that the 18A esc isnt going to work.

yes, the 18A will work easily.

I have not heard of anyone actually having a 9000kv motor yet. Mine all measure around 7000kv.

I kind of like the Art-Tech F-86 more than the Great Planes version. The biggest issue is that it's a porky 140g RTF vs 67g... DOUBLE the weight! Though to compensate to a degree the Art-tech model is somewhat bigger at 45cm wingspan vs 38cm.

Other advantages are having 2x servos for ailerons, 3S battery and removable wing.

Having said that that it could easily shed some weight as you could lose those 8 magnets for the wing, and uses 1.7g servos instead of those beefy 3.6g servos. I bet you could save 10-12g with lighter servos and removing those magnets and not fitting the fuel tanks or wheels.

It looks like a better design than the J-Power model with more space in the canopy area for battery and RX.as well as a neat tube to house the aileron servo wires.

If I didn't already have the J-Power F-86 I'd snaffle up the Art-tech one - assuming I could get it here in Australia without paying squillions on postage! Maybe HobbyKing will stock them?

I think a main advantage of the Art Tech version is the EPO foam (which is why it is heavier). This makes the plane almost indestructible vs. the EPS foam of the HH UM's. It also means it can fly better in windy conditions.

The main reason I like UM's is the "pick up and fly after crash" characteristic. Otherwise I have plenty of other jets already in my stable...

I agree with your ideas for mods...Too bad we can get one as a "Kit Only" with only the fan and motor like the SkyAngel version.....The one thing that I don't like about it is the weight as it weighs about the same as my SA MiG...I won't fly that one in my back yard as the landing speeds are too great...I have the GP Sabre ordered as the lightness/less mass will allow me to enjoy this from my back yard, flying from my back porch/patio!!!......

I wish I have not seen your post. After seeing your post, I did a search on the Great Planes micro jet and I am poisoned! The indoor flying clip looks great!
Now I wished I haven't bought so many Jpower micro EDFs!
