    Parts Wanted .67 nitro engine 1/4” square drive collets

    If you don't mind having a multipiece collet, most of us are running Speedmaster round collets with square inserts. Harry sells these with either round or square inserts. If you want a single piece adapter, best to give Lenny Blake a call.

    Thanksgiving weekend records trial hosted by Huntsville Model Boating Association

    Thanks TK, however Joerg is over 200mph now, but can only do so at an Olympic rowing type facility. I will have to design a new rigger to come close and run at a similar facility or open lake with a GPS.

    Bearing Istallation

    I believe Jim also favored steel bearing carriers for his motors to match the thermal expansion of the case with the bearing more closely. You can run tighter tolerance bearings in cases that have a similar CTE.

    Thanksgiving weekend records trial hosted by Huntsville Model Boating Association

    Adam Grim broke the NAMBA SAW and 2-lap records with his twin gas rigger. Sorry the video is rotated and I was not there for the record runs but I believe the speed was 93mph for the SAW and 17.8s for the 2-lap. Wally Duarte also broke an IMPBA record, but I cannot recall which one and did...

    Thanksgiving weekend records trial hosted by Huntsville Model Boating Association

    If you were not there you guys missed a hell of a records weekend. It was chilly! The temps were below freezing in the morning and air density was as low as -1300' on Saturday morning. That made for some nice conditions to burn some nitro or gas and not so much fun trying to keep lipos...

    How soon to charge race packs?

    100% agreed with what Grim mentioned on transport. I use a metal flip top toolbox lined with foam to electrically insulate from accidental grounding. I highly recommend covering both the positive and negative terminals with tight fitting caps to prevent accidental contact.

    How soon to charge race packs?

    For safety sake you should always charge them right before you use them and in a controlled environment. i.e. charge and stay in the same area, don't walk away and do something else where you cannot keep an eye on them. For best performance: Warm the cells to at minimum 80F before...

    T4PM Won't Display RX Voltage - RESOLVED

    Yes, that is correct. At minimum you should see the receiver voltage. Read through the T4PM manual starting at page 122 and see if your settings align.
