Hi Guys,
My Vanquish shipped from Chris yesterday, very exciting. He was good enough to subsidise freight to Australia (current deal he is doing) which was mighty good of him!! I am buying to practice my F3A patterns, flying advanced at present so I need 7-8 mins per flight (would prefer 10 or so)
I've got a motor around the size of the recommended one so I thought I would try this one first before buying an other motor. It is an Hyperion Z3025-10, specs are: 815rpm/v, weight 186gm (~6oz), length is 50mm (excl shaft). I have a CC 45 that I plan to use. So to my questions:
1. I'm not sure how to mount as I haven't seen this part of the build on the thread, can anyone advise or send a couple of pics please? I'm also not sure if my motor is longer or shorter than the Torque model recommended, can anyone advise?
2. Battery 3S or 4S? 4S would get me up to 480 watts, while 3S would produce up 350W, I'm thinking I would need 390 watts for a 1.3kg model to have excellent vertical performance? Do I go with a lighter 3S or the grunt of 4S?
3. Battery capacity? I used a 3700mah 25C pack with this motor previously and it was excellent, would this be too heavy?
Any advice or thoughts appreciated.
All the best, Simon
Hello Simon,
Congradulations on purchase of VERY nice plane, im sure you will enjoy it, first thing you have to do is setup it right. I spend allot of time by picking up right packs , so i try to make your and other people choice easier.
1. I never had such motor, i hope you can put it on nose of vanquish with no problems. One think you have tyo keep in mind, is right CG, since your engine is already 186g and Torque 2814T/820 is 143g so you will have 43g on nose, this can be problem by setting up right CG specialy with noseheawy plane. Anyway here is my vanquish motor mount with motor in place, as you see motormount is made for backmounting:
I made measurments with cowling on top, so it might be wrong by few mm, but you should get main idea. Hole in front of Cowling is ~ 35mm.
2. This depend on what you want from plane, if only pattern and little 3D flying go with 4S this ans ~APC 12x6e prop (This is setup i fly). And if you wan't 3D go with powerfull 3S pack (Flight power EVO 25 should be best option), but for 3D plane must be light and your extra 43g on engine will make big difference. So in your case i would pick 4S pack, with right setup you will get unbelievable vertical performance.
3. Capacity, i use 4S Flight power 2500mah packs that are ~268g. Again because your heavy motor you will have some problems with C.G. But if you planning only pattern flying probably front CG will make not much problems for you. And 3700mah will be to much specialy 4S pack, what is 3700mah weight? Remember Vanquish is small plane, so don't make it to heavy.
With 2500mah packs, i can fly P07 sequence with no problem and when i land plane still have ~20% of pack left (in calm day). Personaly i love most FP Evo 25 2170mah packs, they are just 226g, and with them i never use full power, and vertycals up are faster than verycals down! Also 3D characterystics are much better, but flying time is ~ 6min. So your choice depends on what you expect from plane. Here are example of P07 seq with 4S 2500mah pack:
