TFL Hobbies "Popeye" Hydro: P-Sport Hydro

[ron1950]

not sure if this one is small enough maybe doby can jump in here but go to parts and props and cnc and 3 blade and the first one is a 46mm

I try and always use my trusty Graupner 'K" props to try and establish a safe baseline for heat vs run time vs handling.

They are inexpensive and you don't have to really do anything to them but bolt them on and run. Personally if I were running a 2200kv motor on 5S, (40ish thousand rpm unloaded) I would start with a K45. Run for about a minute and bring it in and make sure everything is happy. My best settings on both my p spec and p sport are with the strut set so high that its almost touching the bottom of the hull. It seems to air the boat out nicely. (I modded the strut to allow for extra adjustment).

Right now on my p sport, I'm getting decent speed and temps with a K51....seems to run easier on the electronics than the 3 bladed 50mm CNC prop.

Thx Doby. Just did a Google search and can not see where to purchase the Graupner K 45. Do you have a link to them? Also are they carbon fiber? Jeff

[Doby]

Look under props at OSE...Thats where they come from!

Lol thx Tim. Geez they are only $6. Can't go wrong with that price

[Jlov]

I ordered a K45 and K48 and will give them both a try. I ran the Popeye today will be uploading a video tommo from a on board camera I bought from Hobbyking.

[Jlov]

Well heres the video its a little shaky at times. The camera was only $20 from Hobbyking and guess you get what you pay for.

[Jlov]

Ok guys out of town till Friday. I'll post some vids this weekend. Jeff

[Jlov]

Got a K-45 & K-48 in Mail today from OSE. I'm going to try them tommo and will post some video and hopefully some faster speeds then I was getting with the Y547.

Some really great info and knowledge in 1 place. Great thread.

Sounds like most of you guys are setting up to run in a class with 4S power. I am sport running and would like to run a setup bye you guys before purchasing parts. I have a quote request for a green fiberglass version in with Monica at TFL and am trying to figure out the best motor/battery combination.

Does anyone have experience what is the upper limit on speed with this hull?
I would like to be in the 60-65+mph range. Does this seem possible and moderate level of control ability? I saw Doby's video at 61mph with some wind so I am thinking possible, just want to make sure.
I am thinking on going with 5S2p with a Neu 1515 2050kv or Leopard 2000kv 4082. Starting with a M445 and going up from there. Open to suggestions if this is a bad direction.
How heavy can the batteries be without making the boat too heavy/handle poorly? Was thinking of running (2) 5S 3300mah or 4500mah

I just got done with my 1st FE build which is a mean machine 4S2P Dinogy 6000mah batteries 1515 2200KV , M445 prop, which is GPS at 54mph with some more tuning to go.

I would like a hydro faster than the MM. I have a UL-1 also that I would like the Popeye to replace. I wasted so much time and money messing with that hull to learn the hard way it is not happy over 55 mph. Don't want to make the same mistake with the popeye.

Thanks in advance for your help!
