Hey guys,I just got a hyper 7 tq sport 2 days ago and I must say im not impressed.Now before you all think im attempting to bash the buggy just let me explain and i also have a couple questions.So the break in process went ok then i took it to the track for the first time today and heres a list a problems that i had in 15 mins at the track.
1)Broken steering knuckle
2)pull start got caught in back tire somehow and got shredded
3)Silicone maifold seal on exhaust got burnt and mended to exhaust(came factory shipped with a loose manifold)
4)Steering servo plastic gears grinded to crumbs
Now before the assumptions start that im new to the sport and dont know how to run a car (let alone control the thing) I have been doing this for 12 years consistently.I have:
Nitro Evader St
Associated RC10GT2
Losi 8ight
T-Maxx
Ive never quite experienced such quick problems.Anyone else had similar problems?Next question.Im going to spend around $300 on hop ups.What hop ups should I start with?Lastly.Believe it or not the fastest car i own is the cheapest (nitro evader st).So question is,why doesnt this Macstar .28 compete with a little CV-XR .18??Whoulda thought that??
First lets start with the speed comparison. You havnt even gotten the engine fully broke in yet and you are comparing apples to oranges. The power to weight ratio of a two wheel drive 10th scale and an .18 engine is not in the ball park and 40 mph is all should expect from an eigth scale 9lb buggy with very low gearing. Most .21's are faster in buggies. Why they put .28's and pull starts in buggys is beyond me. Now the pull start. You have to make sure the pull start fully retracts after starting the car. It can easily get stuck on the body and if you flip it onto its lid and back onto it's wheels,the handle can get drug out far enough to get tangled around the rear end. As for the knuckles in front, they are cast and every once in a while you get a bad one, that is with all brands. Now buggies take the most pounding of rc off road. They need to be properly prepared. RTR need special care. You should never rely on the build process from a little girl from some far away land to build your car like she was going to drive it. Check your servo saver, change the diff grease to fluid, lock tight all your drive cups and forget about the servos that comes with these cars. If your servo saver is loose enough you can get a couple runs from them at best. Upgrade it and it will steer better as well as last much longer.
