1/8TH Scale IMPBA 8s or 10s ?

[Ron Zaker Jr]

What are most guys running,8s or 10s in their 1/8th Scale FE.? THX.

 

[Mike Starrett]

At Evansville this fall the 4 entries were all 8s, 850kv motor, 57mm max prop and we ran 5 laps. These are basically the rules they use out west. We have used the same setups at our races in Madison, In this past year (6 races there).

@ more are being built on 8s one is mine

 

[Duke Mordja]

I Hope to have one for 2023. Another Miss Madison if all works out. Probably be 2024 though.
Ron needs someone to race.

 

[Mike Starrett]

I have talked to Jeff Henderson and Al Archer about this. I think they are interested as well.

OK 8S sounds good thats 2 4S battery, so is there a preferred charger that will do the job charging 2 4S battery?
Just thinking ahead

Phil I have a venom dual charger. I need to upgrade to a quad charger.

iCharger 406 Duo works great. You need an external power supply.

With the recent release of the Castle XL2 being the best affordable almost bulletproof controller we have seen in a long time and 8S capable I would opt for 8S all day long. 2 4S in series you can use all those P batteries you already have.

I am planning on running electric 8th scale for the 2023 races. 8 cell sounds fine to me. Just want to run at all the tracks

 

[Samuel Hagan JR]

Sounds like me and David need to get our butts in gear for next years 1/8th FE scale class.

We’ve been running FE 1/8th Scales here in Texas under the NAMBA rules for the past couple years, and we race six full laps with no problems at all.

 

[jevmax]

8S per NAMBA rules. We easily run the full 6 laps.

Great Duo ACDC Charger for a fair price.

When I show up with a 10s boat, will I be turned away?

 

[K.R.Joye]

Good question Tom i'm in the same boat(no pun intended)

 

[Duke Mordja]

In D4, when clubs define 8S in their race registration, there isn’t any sense registering or showing up with 10S. 10S will not be racing against 8S.

In D4, there will be 8S Racing in 1/8th Scale. If enough interest in 10S 1/8th Scales - (3 or more boats) I think clubs would add a 10S Scale Class.
Love to have a separate scale class for 8S AND one for 10S.

 

[Tom Kelly]

So your telling me that 8s is more than a "Madison Club Rule", it's a District 4 rule as well?

 

[Duke Mordja]

Tom,

For 2023 it is. The racers in D4 building 1/8 Scales (about 7 or 8 boats) wanted to match what D14 is doing - since D4/D14 racers compete at a number of events each year and wanted the D14 and D4 boats "compatible" for a better word.

The scale registration form on the IMPBA website defines what we are looking for in D4 for 2023.

Here is link to IMPBA D4 Scale Registration Form:

D4 2023 SCALE REGISTRATION

I'm real familiar with the rulebook. Here is what the IMPBA website has for Scale FE

In the event that the boats that have a tie are in 5th place, both boats go into the final and the final field of 6 boats is established.
f. At the International Regattas only, due to US1 status, Scale boat racing will revert to US1 standard heat racing rules.
