H&M lobster rigger set up issues

[Jesse J]

Got this less than a month ago and here is the second run.
Castle 1515 1y, 4s 6200 mah, abc 1916, randy rap turn fin.
Possible causes:
Starboard sponson curves up at transom
Turn fin is not flat
Torque roll
Strut is too low
Or I hit the barrel roll button without knowing.

Too much power. Hull was designed in NiMh days. Maybe higher kv less prop?

A smaller prop? V90 series?
You def want a detounged prop, as the tong helps with accelerations

That hull was always cranky. I remember watching Dennis Whitt try to make one work at the old Houston club’s Hydro Shoutout in 2004. Due to the narrow transom, once the sponsons left the water even a little bit it would roll over. As I recall - it’s been a long time - moving the CG forward biased towards the left to plant the sponsons helped. Putting a flat ride pad on the funky right sponson would help keep it on top of the water too. Oh, and ease into the throttle, even back in round cell days there was plenty if power (and weight) for this hull. Good luck.

Well now that was interesting to watch. What's the KV on the 1515? How long is the Hydro?

[Jesse J]

Thanks all. Lots to tweak here.
My problem is that it has to look like a boat.. so this is probably the only rigger I’ll run..
The boat is 31 in, and motor is 2200kv.

update--> the answer to my first post: torque roll!
see below video of first run stepping down from 1916 prop to a 1716..

That made quite the difference going to the smaller prop.
