    This is what i do when i cant run my boat......

    Well its been cold lately and I decided im not going for a swim should I flip my boat and for some reason my recovery doesnt do the job. I kinds been slacking on it anyway but after last weekend its almost done. Just waiting on a couple more parts. Anyway, I have to have something to keep me occupied and I have a couple rc buggies. I've gotten on this kick of trying to see how fast I can make something go that totally wasn't designed to do it. I picked probably the worst vehicle for going fast but it looks the coolest by far. Its an axial exo terra buggy. I sank more money than I care to think about in this thing. Ridiculous. I took it out today and did some speed runs with it. Beat my goal too. I was shooting for 70mph. Heres some pics.

    Sand mode!

                  Well I never had any axles break. Im still using dog bones. The cv shafts do break and I learned this beforehand so I never bought them. I have stripped the diff gear, spur gear and spider gears tho. Everything has been upgraded to hardened steel parts and some billet suspension pieces where needed. Heres the 72.9mph run

                          Thx! This coming weekend im going for 80mph. I have to change the spur because I've run out of pinion options. I have a 25t pinion in it right now. It still has gobs of torque down low so I know I can go up some more. The problem is the next size is a 32t. I didn't want to jump up that much. I have a 52t spur in it right now, im changing it to a 46t or 48t, can't remember which one I have. Getting old I guess. Lol. Heres a knock around video to shop you the torque it has.

                          The above videos are with a binding rear diif that I was unaware of. It scrubbed off about 5mph of speed from normal and the motor ran hotter along with shortening my run time. I failed to away the diff cup correctly. You live and learn. Lol

                              Nice stretch of road you got.
                              I like it running on 3s!
                              Did you get the RTR?
                              I have one of those Hobbywing 1/10 BL motor ( sensorless) , when they just started selling at Xheli, it was like $70 for the ESC and motor. Great motor.

                                  Actually that stretch of road is short. I have to be careful because sometimes I cant stop it before the curve and it'll go flying. Lol. It is the rtr version. Almost everything has been upgraded or replaced besides the chassis and cage. I have a reedy 550 sl motor. They are about $55 new shipped. Seems to be an awesome little motor. I took it apart and put ceramic bearing in it and it looked pretty well built. Temps stay under 160 even when bashing with a 25t pinion. I heard the hobby wing motors were pretty stout but I ended up buying a 4600kv tenshock 411hd the other day. I haven't tried it out yet. Its a sensored motor and I was told they go pretty good. On a side note, on 2s I gps it at 53.9mph yesterday. Pretty stout on 2s. Lol

                                      I thought I saw HobbyWing motor, my bad. So which motor was used in the video? You get the Reedy at Towerhobbies? I like sensored motors too, I got two of the early Novaks and put one in a Traxxas Stampede and another in an Associated RC10 TC3 RTR. it rips!
                                      I was eyeing this Exo Buggy but spent the money on another boat, lol...
                                      What is the stock pinion gear tooth count?

                                              Im not sure what pinion. I think its a 14 or 15t. I had the reedy motor in it. I haven't even run the tenshock yet. Heres the motor I have in it

                                                  Heres something I did last weekend. I converted a nitro 1/8 buggy to electric. I made the motor mount, battery tray and electronics tray. Pretty easy actually. This thing flat out rips. It has so much torque on tap that the acceleration is instant. I have a 1512 2650kv motor in it with a mamba monster 2 esc. Sound familiar? I stole them out of one of my boats lol. Guess im gonna have to buy extras now because this buggy is too fun.

                                                  Mount I made. Notice I didn't want to be limited on pinion size lol








                                                  Heres the buggy getting some air

                                                          Looks good, I might have further questions to ask , have a 1/8 buggy sitting on the shelf for the last 7 or 8 years, been thinking doing a conversion.
                                                          Anyway, at work and I have not had the time to go over everything you wrote. Thanks tho!
