The watt meter will tell you 3 key measurements but the one I use for historical motor selection is watts per pound. The greatest thing about e-power is that your weight will not change as your tank ( lipo ) empties.ģ) Buy two inexpensive tools - one is a simply digital luggage scale and two is a watt meter. Its the most proven CG starting methodĢ) learn to use your lipo for key CG movement so you need to be able to move your lipo forward and aft so your not adding dead weight. Sir I suggest the following for you being new to epower and one rule of thumb on CGġ) on CG use google and secure the formula for 25% of Mac. Since I use Jeti telemetry, the data will be shown on the transmitter display. I will still have to check them in practice. these data are only calculated parameters. The drive calculation was done with the Drive Calculation from ecalc.ch. Propller is an APC-E 12x8" 2 blade prop Static Thrust ~2200gr / 77.5oz, ~152W/kg (69W/lb), 13 x 8" would also be fine. the model will be electric, with a Hacker A-40-12S V4 14-Pol (kv610) (198gr.) and 4S1P Hacker Eco-x 3000mAh LiPo Accu. It seems to me that the model will also have a pretty high wing loading and therefore also wants to be flown fast. Is there anyone else who has an AT-6 from VQ Models and it still flies well. This difference can be crucial between flying well and crashing. On the other hand, position 1 could also be correct, because the wing is a trapezoidal wing and the extension of the leading edge meets in position 1.
I'm guessing that the 88mm is measured from position 2. Sorry to dig up this 15 year old thread but I just decided to build the AT-6 from VQ Models and I am a bit unsure from which point I should measure the 88mm that the manufacturer has specified for the cg. The HVs are realy nice.but they are not cheap I like using castle creations phoenix controllers with a UBEC. If so, then I have to go with a HV controller which jumps up in price. The big decision for me is usually wether or not to go over 6s. The AXIs can take alot of juice, the secret is to watch your heat. In my opinion, most manufactures underrate their motors for obvious reasons. Most would tell you that the motor can't handle it.but it does! And it is FAST. My buddy Jay has that motor in a P51 that he flies on 8s. I will use 6s and it should be a nice flyer. I am getting ready to maiden a FW190 that has a e-flite power 60. The F104 is still in the box, I will start it soon, should be a easy build, one to two days max. For some of these big planes, batteries in the 3600-4200mah range are the ticket. Most of my batteries are tanic 3250s and 3650s.

A large 6s, is that.a large 6s, but two 3s can be either paralleled for a large 3s, put in series for a 6s, or simply left as a regular 3s. For batteries, I have 2s, 3s, and 4s batteries, so I can build the pack I need. I had planned to use 6s, but the 7s made it SCREAM.
