Though not legal for 424 right now, a composite bolt on V-tail is $75.

Hollow molded tails have been legal for 424 since 1/1/2017.
Check the rules and look at the change history.

Deleted...wrong answer.

Agree on the size and how to get everything to fit. It is a glass fuse that I have so wondering if I can cut the top off for battery access, like the EF1 canopies. Not sure how easy it will be to get an EF1 motor to even fit. But worth the try and see what can be done. There are some nice small high...

Chris,
just 110-120? Thought you were in a quest for speed. I am hoping for 130ish or more.

A to be honest, folks are already in the 110-120 range. When the EF1 times are close to the 424 times on the same course, the speeds are about the same.

Craig, kinda came out of the discussion on RCG about why no electric quickies. This post by Duane. Figured I wouldn't mind having a faster electric anyways. Maybe shoot for something between 424 and 426 speeds. I've got a QM P51 fuse and cores to put together to see what i can do. http://www.rcgroup...

Craig, I am guessing there is no issue with running the EF1 motors on 5S. Most of them list 4S in the specification. I currently have the NTM, E-flite, OS and Rimfire. Reason that I ask, working a little fun project on a EQM15 to try and get speeds up over EF1. The initial intention is to use the EF...

if the 15BL is the same diameter as the EF1 motor, and only 1200 KV, what was the advantage to using it.

Jeff,
can you give some details on the motor? diameter, length, max amps/watts/etc? About all I know is that it is 1200 KV.

Looking to do some experiments as well.

Cheers

Hi Dan, about all I can find is for the Eflite motors. Here are the links. http://www.bocabearings.com/bearing-inventory/19866/bmk050-e-flite-motors-power-25-bl-1250kv http://www.bocabearings.com/bearing-inventory/19867/bmk050c-e-flite-motors-power-25-bl-1250kv http://www.rcbearings.com/products/efl...

So I would guess that 1/4" to 1/2" high, vinyl-cut letters, affixed to the bottom side of the stab meets this requirement? EF1 at least can go in the battery compartment. To me saving the five dollars by registering by 1/19 doesn't even register with me. Holding out, in what little hope there is lef...

Any thoughts then on the XHT 4mm that come on the Turnigy 2700 Nanotechs?
