I am just curious as to how fast people have had their delta force monos. I have had great luck with mine, currently building a MK2 with neu 2215 power.

76mph on N2 and 80mph on P with the 26" version. Q mono has run close to 90mph according to the GPS.

Holy smokes! Hats off to you Tyler that’s insane. I got my 29 to 77mph the other day and I thought that was pretty crazy, And to go even faster with the 26 is incredible. What size was the Q boat?
DF mkII 39" for the Q-mono.

Very nice
I've only gotten my mini sniper (24") up to 45 on 3s. What setup you running to get over 70?
I've got a 2860 SSS 3000kv motor and 90amp flycolor ESC with 34mm aluminum prop, 3s2p 2200mah turnigy batteries. and .13 flex shaft. I'd love to get more speed.
Nice! I’d love to have your boat, I have been waiting for a mini sniper to go back in stock on OSE. 45 is already pretty good speed for that small boat. My boat is a 29” hull and I am running a leopard 4074 2000kv on 6s spinning a 1716 prop. I would play with different props on your setup to get a little more speed.
I've tried different props, the 34 works without any issues, I've tried up to 40mm and it draws to much amperage, causes lvc to kick in. Think I would need a motor with higher torque to turn a bigger prop. Was thinking of switching to a 2860 leopard 3200kv, not sure that would be much faster though. Higher quality motor might turn a bigger prop though.
Telling us the prop diameter doesn?t really tell us much useful information. We need the pitch and the overall prop design along with the exact battery specs to recommend something which may increase your speed. Actually for a 35x49mm prop, mid-40s isn?t bad at all. Your fuse is the ESC, to go much faster you need to upgrade. But, as you pull more amps the battery may begin to be a limiting factor as well as the motor. Tyler didn?t get those speeds with an economy motor - I was there when he set one if those records (maybe more but can?t remember).I've tried different props, the 34 works without any issues, I've tried up to 40mm and it draws to much amperage, causes lvc to kick in.

CNC 3414 Magnalium 7075 propeller. 1.88" total pitch. Batteries are 2200kv 100c turnigy 3s two in parallel.
I run a Leo 2860 - 2550kv- on 4S 4500mah and a D/T 435/3 DF 23 Sniper. I have built a couple and wish I never sold the red one...

Jay you have a good memory. Yes I was running high end Lehner motors, but it was the ESC that helped make those speeds possible especially with the N2 setup which was around 500A. I was running a 38mm prop for the 76mph N2 record and 40mm prop for the P record. The N2 boat ran 2S2P while the P used the same cells just wired in series to make a 4S1P. The N2 was running pretty high KV, but the P was only running 2500kv. It was the fact that that the hull as perfectly balanced and rode on the last 1/2" of the keel. I have tried to repeat those runs a number of times with no luck.

Yeah I don't have the money for high end stuff, I've got too many irons in the fire with Rc boats and rc cars, I like playing around with budget items and trying to maximize. Once the kids move out in 10 years or so (hopefully) maybe I can actually put some money into this stuff. (Not that I don't already).
Jay! Hope you are doing well, I need to give you a call it’s been a while.
Ray, what is the strut you used on the red mini sniper?
Tyler, that is remarkable 500 amps for that n2 deal!
Although I used a high end system, you could easily run in the low 70's with a DF26 and a TP3650 motor with a Castle X8S. If you don't care about class records run a pair of small 3000mAh 4S packs and connect them in series to get 8S which will reduce your current draw. Shoot for a 7D or 8D wind and run a X440 on .150 cable or .078 wire. If you get the attitude trimmed correctly 70+ is achievable.
Motor and cooler is $120, ESC is $215 + $40 for the cooler, batts are $50 each for a good 70C 3300mAh 4S pack. So just under $500 for the power system. Sounds high, but could be a lot more.

That strut was direct from Delta Force as were the trim tabs and rudder. Unfortunately Samuel Chan said he had no more when I asked a couple years ago... Sad face
I cleaned off the anodization and polished it up. This is a picture of the first RTR DF23 I owned and again wish I kept...
