I thought we were talking about a jet here. You won't ever go to a jet meet and see guys yanking around a jet.

Oh yeah, and I have seen guys pull too hard at Red Bull air races and the wing drops violently and its over. Id say fly how you want, but no one can blame the airframe for not being able to take full up elevator at 150mph without dropping a wing and snapping out.

Guess you have never been to pylon races.....

High speed stall at air race. Pilot said he pulled too hard.

The 1680 on 8s is about 85-86 amps in the Bu32 and about 123-24 on 10s and yes you have to go down to 4000mah packs as they weigh the same as the 5000mh 6s packs. On 10s you have to go down to 3600-3700s.

For 8s you can also do the 700-60-1738 or the 1865 at 89 amps and 110 amps, but neither will do 10s. I personally like the longer can of the 700-68 and feel that despite the lower KV it outperforms the 1738 due to the extra mass. Same extra mass also mean more area for cooling and then there is the 9s and 10s options as well with that motor. Pair it with an YEP120 and you've got 8s or 9s or and EDGE HV 160 8s, 9s or 10s.

However, having said all that, I if one wanted to stay strictly at 8s and I'd say go with the 1865 and YEP120 or EDGE 130.

yeah...don't do that. Turn left...pull hard...just not too hard. Does not matter if its a jet or prop or glider or a vespa. It's about wing loading and instant AOA. The really good guys throw around the big jets...snap rolls....20 G turns...they have learned the limits and go right to them. And i you arbitrarily yank full aft stick...you deserve to crash. With some tuning you could pylon turn a Non-bloated H32 just fine. Crow mix works wonders!

Watch original Horizon H32 video 1:02 1:11 1:30...those are some worthy yanks..and not a twitch of the wings.

Fan market is a finiky place...not worth it. market is pretty much flooded. The V32 system with it's rare 6-pole motor...is one of the most efficient fans systems anywhere...yet people don't like the sound. 6 months from now people will want 1-bladed fans that sound like kazoos or something...and high blade count fans will be soooo 2014. Horizon knows their market and where to spend the NPD funds...that is why they are numero uno. Get the V32, put it on 6 or 7s and buy some ear plugs or drop a Wemo Evo 80mm right into that V32...on 6S and done. There are a bunch of other rotors...just need shaft adapter.

...or you can wait..and they will probably announce a new fan soon and prove us all wrong
Efficient as it might be, it is still lagging far behind in terms of performance and sound, that's why so many choose to not use it.

I still think they will announce a new fan soon if for no other reason than to simply refresh and update a 4-5yr old product..

Agreed...sound is not ideal...but at least you can hear it when other planes in the air. Performance is relative...depends on what you are trying to achieve...if you want max power to weight (incuding required batteries) the V32 is unbeatable. If you want top speed at the cost of weight and increased stall speeds...then the V32 is not the ticket. I do hope they come out with a Multi blade fan but more like a 7 or 8 blade with a smooth sound...but little more mid-freq noise...like a Hayoe sound.

I'm not sure the V32's 1400watt setup is unbeatable these days, perhaps it was when it first came out.

A HET 2085KV with JetFan on 6S will weigh the same but perform near 50% better, of course at the cost of greater amps.

--I run a Freewing F-86 with V32 setup and intake ring installed... it has a very nice whoosh sound with just a tad of whine... sounds very nice and get a lot of compliments on the sound...it sounds more realistic than the quiet, stock 12 blade unit.

--V32 is a great setup for 6s or 7s

Yes, it will haul butt..for 3 min.

The V32 seutup is at least 6oz lighter setup just in the fan and motor....!!! Then you can drop to 4Ah battand save another 5 oz .. its like a 11oz diff from HET 700-60/jetfan which is huge....or leave in the 5Ah batt and fly for 5+ min. For 3.5 mi flight...you can use the V32 with a 3000 mAh pack and drop another 3,oz and it would just float.

The point is....people always have to go big....but the person who can be happy with the stock system has some major advantages in handling and flight times....just not top speed. Not that i would go that route because that fan noise is piercing! Give credit to a little 150 gram..28mm motor and simple fan that makes 4.5 lbs thrust installed for only 1400 watts!!! If the sound was just a little more tollerable (but still loud enough to hear) i would be all in.

On 6s? Eflites own numbers are 4.5lbs and 1400watts. What batteries? 2400watts, stock motor and fan?

Totally depends on what fan you run. I have a SM80-45 in my 32 and with the esc behind the motor i need 30gram of lead and a Rx battery up front, and I still have to push my 6S 6000 pack all the way forward to balance the plane. So with my setup a little shift in the cg would be nice.

--V32 setup is a lot quieter running on 7s than running on stock 6s

Maybe, but it still sounds like a dentists drill compared to a Jetfan 80 or a Stumax. And these fans also have a lot more potential for higher power setups as they use 39mm motors.
