Darin's Top Speed 2 FE Conversion...

[ice329]

Humm your setup is a bit differnt then mine. Will give what I got a shot today then try the way your is.

I asked on one of these threads about the weight of the TS2 verses the VS1 I came accross the listed weight of the TS2, and it is quite a bit lighter at 2.125 lb verses 4 pounds of the new VS1

Length: 30 in (762mm)
Width: 11.5 in (292mm)
Height w/o engine: 5.75 in (146mm)
Weight (hull only): 34 oz (2.125 lb (964g)

That's the RTR weight for the VS1... You are comparing it to the "hull only" weight for the TS-2...

The TS-2 RTR is going to be about 10oz heavier than the VS1... But I wouldn't let this bother you too much... Weight is NOT always a bad thing... Look at most of the Nitro Tunnel setups out there... They have lead taped to the sponson tips, etc...

re :

All the angle drive needs is an electric motor mount.


You guys might like these for mounts:

I'm taking my time developing the mount configuration. I take seriously Grimracer's comments about avoiding oversteer [spinouts] so I want to get the pivot inside the rear sponson tips as much as possible. Here's some choices :
[ L to R ] : the jack plate pivot mount with the back adjustment ground off [ hate to sacrifice my spare, but..] , the Dubro modified by re-drilling the metal plates to move the pivot block closer to the transom, or the simple mount that came with , IIRC, the TS-2. #1 & #3 would use the angle shims that came with the TS-2 for tilt. I'm also ordering today the Hyperformance mount to see if it's the best choice, gambling $ 21.95 to find out.

I am not worried, I just came accross it and figured I would post it. My boat weighs
5 lbs 12oz RTR that is with the packs in it.

Even if the hyperformance mount stick out too much, since it looks to be solid metal, you can grind a bunch off and drill and tap new holes.

Another idea would be to modify the boats to bring the mounts further in. Then you guys could keep your fancy mounts.

The Hyperformance mount 'll be here tomorrow & then the sorting out begins.

The TS-2 could have the boat shortened to accomodate the longer mounts, but the VS-1 would be way more difficult - I already considered that idea but rejected it ; too much surgery on a wood boat.

I used the Hi-Jack mount straight up on my TS-2 with the REK lower and it handled great... No issues at all... at least not up here in our water... It did act funny down in California at Lake Minden... but I think we sorted that out as needing a different prop for that water...

Different tunnel like different pivot pin locations... The TS-2 was designed to use the OS-Max motor, which has it's own mount assembly... Figure out where THAT pivot is located, and try to get as close to that a possible... Mine would up just like Tony's is, and both handle fine...

I'm betting the VS-1 is designed around using the OS lower as well, so it should have similiar mounting needs...

I wouldn't vary much from how Mike has her designed.... it's a proven race winner and a hell of a boat right out of the box... Just have to adjust the the battery load (extra weight)... but otherwise, leave it alone!

One more thing... I have a couple of the OS mounts at home... I can measure the distance from the plate to the pivot tonight... I'll post the measurement later...

Cool ! - After reading some old posts by Z-man about Randy's first Hooter build & the instructions on the VS-1 I'm now more aware of the importance of this dimension.

Rain didnt stop me today, had to take it out and see what the adjustments did. All I have to say is I am glad I didnt sell this boat. I will still fine tune things before the video but overall the boat is definalty close to being like I like it. Made some artificial waves in the pond by jumping on the corner of the pond boat, then took out the TS2 again. Definatly a fun boat. Thats it for now, I have to take the outboard apart and regrease it, this job I dont care for its a little bit of a PIA.

I would like to see someone put steps on a tunnel.

Only one set at the very back, but I think it should help air these hulls out even more.

[Darin Jordan]

The distance from the base of the mounting plate to the center of the pivot pin on an OS-Max lower unit is 1/2"... 0.5"...

Hope this helps...

Steps in the tunnel would kill the lift... you want the tunnel to be a continous surface with minimal pressure changes. Steps in the sponsons, sure... but the tunnel needs to be a good airfoil, and good airfoils don't have steps...

The TS-2 already has steps on the ridepads, by the way... The FASTEST tunnels out there, however, don't... At least not that I've seen... (Lynx, Villian, WoodStuff, etc...)

Thanks. The Hyperformance mount should get here today; then decision time. Meanwhile I'm going to the lake for some fun !!

Just for the record. I tryed a P741-4 today on the TS2. Although I was able to get it up and running fine, and it does work good it is very touchy and you suck air with any manuver other then gentle turns. Maybe if the motor was lowered but I will say this prop is out for the TS2. If you gun the throtal at a full stop the boat lunges into the air approximatly 6 to 8 feet, needless to say I was messing around, something I never do especially with this thing and I lunged it into the air and flipped it. My water proof box isnt so waterproof...heheh In a panic I flew out and got her. Lipo's got a touch of water but hopefully nothing serious, the rest of everything is fine. Gonna need to see how the water got in and test the lipos...they been sitting under a just warm hair dryer for a few hours...
