modifying trigger for childs finger
My 8 year old son races nitro. He can pull the trigger fine but to use the brakes he has to put his finger behind the trigger and push it. I've tried putting fuel line on the trigger but it wasn't enough. I've also tried heating the trigger and bending it. Besides making an insert and gluing it in, does anyone have a good solution, or know of a smaller radio We went to the hobbyshop and tried a few other radios but none were any better, but they didn't have much of a selection. Thanks

how about wrapping some dubro foam rubber around the brake portion and strapping it with tape or zip ties?
it is a rather dense material compared to basic foam

What radio is it? Airtronics can adjust the trigger to the left or right if your finger can't reach all the way around. Look for a similar angle adjustment. They come with the center insert in them and 2 spares so you wouldn't necessarily notice that at the LHC.

To the OP. You sir have described one of the secret tips that pros have been using for decades. You are also doing what you can, tubing,foam,bending etc... all are tried and true. If you can't get the grip comfortable and trigger functional it kills your driving. Surprising how few people consider it.
neospud, he is talking about having the finger touching both sides of the fingertip when driving. The gap that is between the fingernail and the trigger on the brake side is a delay and disconnection between your finger and the radio. With that gap eliminated the delay between your finger and the trigger is elimnated and control is increased.

As i said i can't speak for other radios but the MT-4 and the M12 come with smaller grips and trigger shims.
I also think you can adjust the neutral position of the trigger. If you move it more toward the grip you should be able to reach the brake easier. You'll have to re-calibrate your throttle.

Idid the same 4 a 8 year olds radio.. the LHS by me have nitro fuel line in many sizes from 1/2" down try getting a few pieces on by overlaying also try medical tube..They also make a foam hockey tape that works well also just a few layers thick..Or get a piece of UHMW and put it in oven heat to 325 degrees and mold that to brake side of trigger then trim with Dremel tool (when it turns clear its ready to work Use protective gloves so u dont BURN ur fingers..

On a couple of my radios(dx3r,dx2,and an oddball cen tx) i modified how the trigger assembly mounted in the radio. I angled it so the trigger would be closer to my finger at the end of the throw. All radios have the trigger running straight ,while your finger swings in an arc. I think i made a thread on my dx2 a couple of years ago. Pm me and i can email or text some pics.

i was hunting for a charger one time and went by prc
they have something called sugru.
its a moldable rubber that dries. maybe mold it to your sons trigger and then place his finger in there to form it to shape then let it dry over night?
just a thought. never tried it but just remembered it

there is a video showing how strong it is at the bottom of the page

Hmm, have you thought about getting one of those cheapo remotes from a toy grade car ? they are small and with luck have the neccassary electronic features.

i think the dx3e is one of the smaller radios out. my 4 year old boy doesnt do to bad with it.

Thanks for all of the ideas. I see a few I like and will try them out.
