whiplash Sport 20 help!

[Bill Gibson]

I haven't run my boats in a while, and want to get my whiplash back together for a race, and I have two lil problems:

1- Cant find the prop I had on the boat, seemed like it was a grimracer 3 blade prop, cant remember the size....can anyone jog my memory? I remember the boat ran good with it!

2-I need a small 4.8 volt receiver battery pack/Futaba J connector for the boat...I used a Futaba R4K 250mah NiCad flat pack, but I guess they don't make it anymore..it was a good fit!

Appreciate any suggestions on the battery, as I haven't a clue where to look, I just know there AINT much room in the boat for the battery!

Many Thanks! Bill

I have a 447/3 blade. Seems to be the best one for us.

Hey Bill,

Good to see you getting ready to run again. 250 mah sounds marginal. No substitute for reserve power. Have Fun.

CHEERS !!! Bob

Bill, If it was a Grim Racer prop it was prolly the 40X53/3

RX pack, look into the LiFe RX pack Tower carries a couple of small ones 500MaH thats good-N-small

Take a look at Value Hobbies for Life batteries. Good prices and service.

Do you mean X437/3? I've run the X437/3 on my Sport 20s.

Seems like it would take one really healthy 21 engine to pull a X447/3.

I think Mark is correct on the prop size 40X52/3

 

[chris thornton]

the prop i use for our sp 20 is a m440 with a lynx cut and it runs fairly fast.

[Bill Gibson]

[brad nichols]

If you have a local hobby shop take the boat there and size up your RX pack?

Sam,

I think you are talking about a Sport 40 boat with a X-447/3.

I don't think there is a production motor on the market that will pull

A X-447/3 on a Sport 21 hydro. Can you send me a picture of your

Sport 21 hydro Sam?

Thanks,
