CoG good with 2200 3S ... 

Soloshot TAG meant moving RX to accommodate ... 

Painting base colours (poster paint) is near complete ... then a thin coat of varnish to lock the paint as its water based. Invasion stripes and then she's ready to go.

Wattmeter :

Battery at storage level (I like to see what worst case is) ...

14A, 140W .... 3S 2200

Thrust feels a bit weak !

Will try with full charged 2200 and see what we get.

Full charged 3S 2200

17.2A
202W

Thrust static at 700gr

Flying weight = 870 + 197 (lipo) = 1067gr

= 0.66 to 1 Power to weight .... UGH !!

OK ... 
7x3.5 3 bladers Gemfan : 17A, 700gr thrust .... not enough
8x4.5 3 bladers Gemfan :  42A, 1450gr thrust !! But very short flight time on a 2200 3S
7x4 3 bladers MAS : 25A, 980gr thrust ..... that's better and allows moderate flight time on the 2200 3S

Motors are 2210 1400kv

Really annoyed .... 

I had tested at home various battery combos to try extend flight time. I had arrived at twin 1300 3S setup (trying to stay in my stock !) which was similar weight and COG to my 2200 trial. Giving me an extra 600mAh

Yesterday - I pick her up ... install two batterys .... and take-off. She is not happy ... it just does not feel right. I decide that best is to slide her in on the grass and not go for a wheels down runway job.
So after flying about - trying to get 'feel' of her ... I extend the flypast to give me long run in for the landing ... as I turn her, the too far fwd CoG bites and in she goes.

At the time it didn't dawn on me what I had done wrong ... but later I realised.

I had put two 1800 LiPo's in instead of the 1300's ... the CoG must have been so far forward - no wonder she nosed in and hit the dirt.



She's too badly smashed ... so gear will be salvaged and I will build another later.

I must say - in no way was the design at fault - it was purely my stupidity in putting too heavy batterys in her ... 

Shame as she did look good in the air.

Wow, she was flying so well to! Looked really smooth, especially with the heavy battery's up front. Such a shame seeing her crash at the end. I think the maximum I flew with was a 2200mah 3s.

This is an old thread but I figured posting here would be better than starting a new one.  I ordered the plans from FRCFoamies this past week and I am in the process of converting the plans to gcode for my needle cutter.  So I am looking at availability of the current motors and these are the two that appear to fit the bill for a 2S 2200mAh battery setup with 3 bladed propeller.  I could do a 3S battery but I would prefer to keep it light and scale like in performance. 

If anyone is currently building the Mosquito I would like to hear about your motor, prop and ESC decision.  Kind Regards, Dana Hager

Update:
These are the motors I selected based on the current availability.
